The relationship of some negative events and psychological factors to periodontal disease in an adult Swedish population 50 to 80 years of age.

BACKGROUND: Clinical observations and epidemiological studies suggest that experiences of negative life events, especially those manifested as depression, may contribute to an increased susceptibility to periodontal disease. OBJECTIVE: In the present study, the prevalence of some negative life events and psychological factors and their relation to periodontal disease were investigated. The sample consisted of individuals 50-80 years of age from an extensive cross-sectional epidemiological study performed in 1993 in the city of Jönköping, Sweden. METHOD: 298 dentate individuals from the Jönköping study were randomly selected. Clinical and radiographic examinations included registration of the number of existing teeth, plaque index, gingival index, pocket depth, and alveolar bone loss. In addition, a questionnaire about socioeconomic status, life events, and psychological and stress-related factors was used. RESULTS: The results revealed that, in addition to the well-documented periodontal disease risk factors such as increased age, oral hygiene status, and smoking, the loss of a spouse (being a widow or widower) and the personality trait of exercising extreme external control were also associated with severe periodontal disease. CONCLUSION: The findings support recent studies suggesting that traumatic life events such as the loss of a spouse may increase the risk for periodontal disease. Above all, the present results indicate that an individual's ability to cope with stressful stimuli (coping behavior), as measured by the beliefs of locus of control of reinforcements may play a role in the progression of periodontal disease.

Factors associated with snuffing habits among ice-hockey-playing boys.

The aim of the present investigation was to study differences in background factors between ice-hockey-playing boys who used snuff, who had tried using snuff, and who had never used snuff. The background factors studied were the socio-economic conditions of the boys' parents; the tobacco habits of the boys' parents, siblings, and friends; the boys' choice of theoretical or practical upper secondary school programme; knowledge of the harmful effects of tobacco as well as participation in a sport other than ice hockey. Data were collected usinG a questionnaire. Of 249 boys in the age group 12-19 years who participated in the study, 13% used snuff, 34% had tried using snuff, and 53% had never used snuff. The factors knowledge of the harmful effects of tobacco and choice of theoretical or practical upper secondary school programme had no significant association with the boys' snuffing habits. This was also true for the parents' tobacco habits unless their habits were analysed separate from each other, where "mother smoked" showed an association with boys who used snuff. The study also showed a significant difference between boys who used snuff and boys who had never used snuff and between boys who had tried using snuff and boys who had never used snuff; boys who used snuff tended to have siblings who used snuff. Of boys who used snuff, 77% reported that their friends' use of snuff had influenced them to start using snuff. A significant difference could also be shown between boys who used snuff, had tried using snuff and never-users depending on whether the boys participated in a sport other than ice hockey. Snuff usage was not as widespread among boys who participated in other sport activities. This was verified by the multivariate logistic regression analysis where "taking part in other sports than ice hockey" was the explanatory variable that showed the strongest association with the dependent variable. An active participation in ice hockey and the environment, in which this sport is practised, would consequently be a strong influencing factor to start using snuff.

Healing following GTR treatment of bone defects distal to mandibular 2nd molars after surgical removal of impacted 3rd molars.

AIM: The purpose of this study was to study the healing, following guided tissue regeneration (GTR) treatment, of bone defects distal to mandibular 2nd molars (M2s) after surgical removal of impacted mesioangularly or horizontally inclined third molars (M3s) in patients > or = 25 years. METHOD: 20 patients with bilateral soft tissue impacted M3s were included in the split-mouth study. The 2 sites to be treated in each patient were randomised before the 1st operation as to which would undergo the test procedure and which would be the control site. After surgical removal of M3 at test sites, a resorbable polylactic acid (PLA) barrier was attached to M2 to cover the post-surgical bone defect. The flap was then replaced and sutured to cover the barrier. Control sites underwent the same procedure, as did the test sites, with the exception that no barrier was placed. The clinical examinations performed were oral hygiene pre- and 12 months postoperatively and probing pocket depth 12 months postoperatively. The alveolar bone level (ABL) at the distal surface of the M2, as determined from radiographs taken at suture removal and 12 months postsurgery, was chosen to be the primary response variable. RESULTS: Most bone defects showed healing up to 10%-20% of the tooth length at both test and control sites. 2 test and 2 control sites showed no improvement in the bone level. The mean values of bone healing registered in mm from the cemento-enamel junction (CEJ) were 2.6 +/- 2.19 SD and 3.0 +/- 2.20 SD for test and control sites, respectively. Different factors affecting the healing result are discussed.

Healing following GTR treatment of intrabony defects distal to mandibular 2nd molars using resorbable and non-resorbable barriers.

AIMS: The objectives of the present, randomised clinical trial were (i) to evaluate the healing of periodontal intrabony defects at the distal aspect of mandibular 2nd molars using a resorbable polylactic acid (PLA) barrier and a non-resorbable polytetrafluoroethylene (e-PTFE) barrier and (ii) to compare the therapeutic effect of the bioresorbable versus the non-resorbable barrier. METHOD: 19 patients with intrabony defects distal to mandibular 2nd molars > or = 4 mm (on radiographs) were included in the study. The defects all remained 5 years after surgical removal of impacted 3rd molars. Following flap elevation and defect debridement, the defects were randomly covered with, either a resorbable PLA or a non-resorbable e-PTFE barrier. Flaps were repositioned and sutured to completely cover the barriers. Treatment was evaluated clinically after 1 year by measurements of probing depth (PD), probing attachment level (PAL), and probing bone level (PBL) and radiographically by measurements of bone levels on computer digitised images of radiographs taken immediately before and 1 year postsurgery. RESULTS: Both treatments resulted in significant PD reduction, PAL gain, and bone fill. The total PD reduction was 5.3 +/- 1.9 mm for the PLA treated sites and 3.7 +/- 1.7 mm for the e-PTFE treated sites (p<0.05). The corresponding values for PAL gain were 4.7 +/- 0.7 mm and 3.6 +/- 1.7 mm (p<0.05) and for PBL gain 5.1 +/- 1.2 and 3.3 +/- 2.0 mm (p<0.05). Radiographic bone fill averaged 3.4 +/- 1.2 for the PLA and 2.0 +/- 1.6 mm for the e-PTFE barriers (p<0.05). Radiographic bone level measurements were significantly smaller than the corresponding clinical measurements, indicating that radiographs tend to underestimate bone fill. CONCLUSIONS: GTR treatment of deep intrabony defects distal to mandibular second molars using resorbable PLA barriers resulted in significant PD reduction, PAL gain and bone fill at least equivalent to the results obtained using non-resorbable e-PTFE barriers.

A prospective longitudinal study on periodontal bone height changes in a Swedish population.

BACKGROUND, AIMS: This investigation was performed to assess longitudinal changes in periodontal bone height in an adult population over a period of 17 years. METHODS: In 1973, a random sample of 1000 individuals aged 3-70 years in the city of Jönköping, Sweden, was examined clinically and radiographically to assess dental status and treatment needs. Out of the 574 dentate individuals 15-60 years, 433 accepted the invitation and were re-examined in 1989-91, 4 were edentulous and the study therefore finally included 429 dentate individuals. The examination included full mouth plaque and gingivitis scores and bone height measurements on full mouth intra-oral radiographs. All age groups except the youngest had very good oral hygiene with 50% or more having plaque and gingivitis scores below 20%. RESULTS: From the age of 20, there was a general pattern of bone height reduction over time corresponding to an annual loss of around 0.1 mm. From the age of 30 years, about 80% of the population had one or more sites with bone loss of 10% or more. Very few individuals, about 5%, exhibited an individual mean bone loss of 2 mm or more. 17% had > or =6 such sites indicating destructive periodontal disease. These individuals and sites could not be identified in advance based only on previous disease experience.

Caries prevalence and distribution in 3-20-year-olds in Jönköping, Sweden, in 1973, 1978, 1983, and 1993.

Four cross-sectional studies were carried out in 1973, 1978, 1983, and 1993 to collect clinical and radiographic epidemiological data on the dental health status of the inhabitants of Jönköping, Sweden. The aim of the present paper was to use these data to analyze trends in the development of caries among children and adolescents between 1973 and 1993. Approximately 500 randomly selected individuals evenly distributed among the age groups 3, 5, 10, 15, and 20 years participated in each study. The main results show that the numbers of caries-free individuals increased in all age groups. In 1993, the mean number of decayed and filled tooth surfaces in the primary (dfs) and the permanent (DFS) dentition in all age groups was less than half of that found in 1973. Most of this decrease took place during the first 5 years, i.e., between 1973 and 1978. Between 1978 and 1983, only minor changes were observed. There was a further reduction of approximately 30%-50% in dfs/DFS between 1983 and 1993 in 3-, 5-, 10-, and 20-year-olds. The frequency distributions of dfs/DFS for 5- and 15-year-olds revealed an increasing skewness over time: in 1993, a large majority of the children and adolescents had a low or moderate caries severity while only a small group had high scores of dfs/DFS.

Caries prevalence and distribution in 20-80-year-olds in Jönköping, Sweden, in 1973, 1983, and 1993.

In 1973, a cross-sectional study on oral health status was performed on 1000 individuals in the age groups 3-70 years in Jönköping, Sweden. In 1983 and 1993, new cross-sectional studies were carried out in the age groups 3-80 years. The aim of the present study was to analyze caries prevalence and distribution in the three investigations 1973, 1983, and 1993 in the age groups 20-80 years. In the younger age groups (20-40 years), a larger proportion of individuals with good oral health was found in 1993 than in 1973 or 1983. A steady increase in the number of teeth in the age groups 40-80 years could be found, which was also reflected in the increasing number of decayed and filled tooth surfaces (DFS) in the same age groups. A marked decrease in proximal DFS in 20-50-year-olds in 1993 compared to 1973 and 1983 was found. However, a rather large and unchanging group of individuals suffering from severe caries was also observed. This situation demands an individualized caries treatment strategy based on risk assessment.

Possible sites for cylinder implants in Swedish individuals aged 20-70 years. A comparative radiological inventory in 1983 and 1993.

UNLABELLED: The aim of this study was to evaluate the number of possible sites for cylinder implants in an epidemiological sample of adult individuals and to compare these results with those from a similar inventory performed 10 years earlier. This study, which comprised individuals 20-70 years old, is part of two larger epidemiological dental studies of individuals from the community of Jönköping, Sweden, performed in 1983 and 1993. Random samples of 579 and 575 individuals respectively were examined and classified according to the Eichner index. The radiographic examination included an orthopantomogram and a full-mouth intra-oral examination. Only existing spaces anterior to the second molars were considered as possible implant sites. Cylinder implants with a diameter of 3.75 mm and a length between 7 and 20 mm were plotted on the radiographs. RESULT: The most striking result from this study was the reduction by almost a half of the total number of possible implant sites between 1983 and 1993. A certain proportion of existing tooth gaps had been treated with conventional fixed prostheses, usually in small tooth gaps, and this tendency had increased between 1983 and 1993. The need for implants in the anterior frontal region was small but constant (less than 1%) in 1983 and 1993. In the future, implants will be a treatment option in young individuals, most likely in cases of trauma and tooth agenesis. Further it may be assumed that implant treatment in edentulous jaws will continue to increase in relative terms, i.e. the percentage of edentulous jaws that have been treated with implants will increase. In absolute terms, however, the frequency of the treatment will decrease because fewer individuals will be edentulous. Instead, the proportion of partially dentate subjects treated with implants will increase.

Knowledge and habits of tobacco among ice-hockey-playing boys. An intervention study.

The aim of this study was to investigate tobacco habits among ice-hockey-playing boys in three clubs in the County of Värmland, Sweden and to analyse whether health information about the harmful effects of tobacco could change the players' tobacco habits. In addition, the issue of whether there is any correlation between knowledge of tobacco and its harmful effects with tobacco habits was studied. Ice-hockey-players from three ice-hockey clubs were represented and one of the clubs acted as a control group. A total of 252 male ice-hockey-players, 12-19 years old participated. A specially designed questionnaire containing 33 questions on background, socioeconomics, behaviour, and knowledge was used. The boys answered the questionnaire on three occasions. The first and second examinations took place on the same occasion with the intervention occurring between the examinations. The third examination was carried out after 3-5 weeks. The study showed that the use of snuff played a more important role among the ice-hockey-players than did smoking and that they had tried using snuff at the age of 12. The baseline investigation showed that there were no significant differences between the clubs in tobacco habits and knowledge of the harmful effects of tobacco. After the health information, the boys' knowledge of tobacco and its harmful effects increased significantly (p<0.001), but regardless, no change in their use of tobacco was found after 3-5 weeks. Knowledge also increased significantly among the boys in the control group (p<0.001), but no change in the use of tobacco was found here either. No significant difference could be demonstrated between the group of boys who used snuff and the non-users with regard to their knowledge of the harmful effects of tobacco.

Fixed prosthodontics in adults in Jönköping, Sweden in 1983 and 1993. An epidemiological study of prevalence and choice of material.

The aim of the study was to assess the prevalence of fixed prostheses, i.e. single crowns and fixed partial dentures, in adults 20-80 years old in two cross-sectional studies carried out in 1983 and 1993 and to analyse whether the choice of material for fixed prostheses had changed during this time period. The material comprised 586 and 593 individuals. A descriptive analysis of number of individuals with fixed prostheses was made concerning the number of crowns and pontics, the distribution in the jaws, and the materials used. The prevalence of individuals with fixed prostheses was shown to increase with age both in 1983 and 1993. In 1993 the number of individuals with fixed prostheses was slightly lower than in 1983 (44 and 48 percent respectively). There was no difference according to gender. The proportion of individuals with fixed prostheses was lower or almost unchanged in the 20-, 30-, 40-, 50-, 60-, and 80-year-olds in 1993 compared to 1983. In the 70-year-olds, however, the proportion of individuals with fixed prostheses was considerably higher in 1993 compared to 1983. Most individuals with fixed prostheses had a small number of crowned teeth, and about half of the individuals had not more than four crowned teeth. Likewise most individuals with pontics had a small number of pontics. The distributions of crowned teeth and pontics in the jaws were similar in 1983 and 1993. Pontics and crowns were more frequent in the upper than in the lower jaw. Crowns made of porcelain or metal ceramic had increased by 1993 in the 30-80 year age groups, and the study thus confirms general clinical experience that porcelain and metal ceramic are more often the materials of choice in fixed prosthodontics in adults today.

Risk of severe periodontal disease in a Swedish adult population. A longitudinal study.

The aim of this study was to identify risk factors for severe periodontal disease progression in a Swedish adult population between the years 1973 and 1988-91. In 1973, a random sample of 474 dentate adults living in Jönköping County was examined clinically and radiographically. A questionnaire on demographic and socio-economic status, general health, and dental care habits was also used. During the years 1988-1991, 361 of the individuals examined in 1973 were re-examined. A total of 506 (6%) teeth or in average 1.4 teeth per subject were lost between the 2 examinations. 4 subjects had become completely edentulous. The mean loss of teeth in the different age groups 20-60 years was 0.2, 0.9, 1.4, 2.3, and 2.6, respectively. The periodontal bone level decreased by age both in 1973 and in 1988 91. The mean annual progression rate was 0.06 mm for all 357 individuals and varied between 0.04 and 0.07 mm per subject in the different age groups. The presence of periodontal disease progression was defined as bone loss of >20% at a proximal site between the 2 examinations. The most prevalent tooth types with bone loss of >20% at proximal sites were the maxillary and mandibular 2nd molars and the 1st maxillary molar, representing a % of 18.0, 12.8, and 13.5, respectively. The degree of association between severe periodontal disease progression and explanatory variables was investigated using logistic regression models. The dependent variable was no progression of periodontal disease or severe periodontal disease progression, i.e., subjects with periodontal bone loss >20% at > or =6 sites. Age was found to be correlated with severe periodontal disease progression by an odds ratio of 1.05 (CI: 1.02-1.07). The frequency of females in the group with severe bone loss was 58% and higher than in the non-progressing group, 50%. Only 9% in the group with no bone loss smoked as compared to 38% in the group of individuals with severe periodontal bone loss. % supragingival plaque, gingival inflammation, and deepened periodontal pockets (> or =4 mm) at baseline were related to severe periodontal disease progression by odds ratios of 1.03 (CI: 1.02-1.05), 1.01 (1.00-1.03), and 1.03 (1.00-1.05), respectively. In the multivariate logistic regression model, age (odds ratio 1.13 (CI: 1.06-1.19)), smoking (odds ratio 20.25 (5.07-80.83)), and % pockets > or =4 mm (odds ratio 1.15 (1.04-1.27)) remained significantly associated with severe disease progression. Furthermore, female gender and differences in income level appeared in the multivariate analysis to be related with severe bone loss, with odds ratios of 3.19 (CI: 1.02-9.97) and 8.46 (CI: 1.97-36.37), respectively.

Oral hygiene and gingivitis in a Swedish adult population 1973, 1983 and 1993.

The periodontal condition of the inhabitants of Jönköping County, Sweden was followed for 20 years by means of 3 cross-sectional investigations performed in 1973, 1983, and 1993. The study comprised individuals in the age groups 20, 30, 40, 50, 60, and 70 years. The number of dentate individuals was 537 in 1973, 550 in 1983, and 552 in 1993. All individuals participating in the studies were examined clinically and radiographically. They also filled out a questionnaire about dental care habits, socio-economic status, and general health. A clear reduction in the plaque score was seen between 1973 and 1983 in all age groups. With one exception, no further significant change in plaque levels was found between 1983 and 1993: the increase in plaque among the 20-year-olds was significant. In 1993 the mean % of surfaces with plaque was between 30% and 40% in all age groups. Gingivitis values corresponded well with the values of dental plaque; the same pattern with a clear reduction in gingivitis score was seen in all age groups between 1973 and 1983, and an increase in the mean frequency of gingival inflammation between 1983 and 1993 was seen in the 20-year age group. 30% of the individuals in this age group had more than 50% gingivitis in 1993 compared with 9% of the individuals in 1983. The 20-year-olds were further analyzed in a linear regression model using gingivitis as a dependent variable against some socio-economic, general health, and dental care variables associated with poor oral hygiene and gingivitis. In 1993, the most important explanatory variable was gender: significantly more males than females had higher gingivitis scores. The second most important explanatory variable was toothbrushing habits. Together they explained 10.9% of the variance. The multivariate analysis did not reveal approximal cleaning habits to be significant, probably due to their strong connection to gender and toothbrushing habits. In the 1983 sample, no significant explanatory variables were found. It was concluded from this data that it is important not only to renew but also to direct preventive guidelines more towards young adults who have no previous extensive experience of oral disease so that they will not be excluded from dental care and their dental health thereby jeopardised. In addition to preventive programmes aimed at the population as a whole, individual programmes based on risk targeting are also necessary to reduce the number of people developing dental disease and to increase the quality of dental care.

Risk of severe periodontal disease in a Swedish adult population. A cross-sectional study.

In this study, potential risk factors for severe periodontal disease were identified in a cross-sectional sample from the county of Jonkoping, Sweden. 547 adults 20-70 years of age were categorised clinically and radiographically by level of periodontal disease experience. These levels were used to divide the sample into groups--individuals without any reduction in periodontal bone level (60%) and those with severe periodontal bone loss (13%)--which were then used in univariate and multivariate logistic regression analyses as dependent variable. Demographic, socio-economic, general health, smoking habits, clinical, and dental care variables were used in the different regression analyses. In the univariate model, age (20-70 years) was found to be correlated with more severe periodontal disease experience (odds ratio: 1.13; 95% CI: 1.10-1.17). The association with periodontal disease was more pronounced for the older age groups (50, 60, and 70 years). A negative financial situation was also related to severe periodontal bone loss when regressed univariately (odds ratio 2.20 [95%: 1.04-4.68]). Moderate-heavy smoking (> or =10 cigarettes/day) appeared to be associated with severe periodontal destruction with an odds ratio of 9.78 (95% CI: 3.62-36.42). Of the clinical variables in the univariate model, higher mean levels of supragingival dental plaque and the presence of subgingival calculus were related to more severe periodontal disease with odds ratios of 1.02 (95%: 1.01-1.03) and 2.96 (95%: 1.50-5.88), respectively. When the same variables were regressed multivariately, age (continuous) (odds ratio 1.17 [95% CI: 1.12-1.22]), moderate-heavy smoking (odds ratio 11.84 [95% CI: 4.19-33.50]), and higher mean levels of plaque (odds ratio 1.02 [95% CI: 1.00-1.03]) remained significant. Light smoking (1-9 cigarettes/day) was not significantly associated with severe periodontal disease in the 2 regression models. The present study demonstrated that smoking, greater age, and higher mean levels of plaque are potential risk factors for severe periodontal disease in this specific population.

Distribution of periodontal disease in a Swedish adult population 1973, 1983 and 1993.

The aim of this study was to compare changes in periodontal status in a Swedish population over a period of 20 years. Cross-sectional studies were carried out in Jönköping County in 1973, 1983, and 1993. Individuals were randomly selected from the following age groups: 20, 30, 40, 50, 60, and 70 years. A total of 600 individuals were examined in 1973, 597 in 1983, and 584 in 1993. The number of dentate individuals was 537 in 1973, 550 in 1983, and 552 in 1993. Based on clinical data and full mouth intra-oral radiographs, all individuals were classified into 5 groups according to the severity of the periodontal disease experience. Individuals were classified as having a healthy periodontium (group 1), gingivitis without signs of alveolar bone loss (group 2), moderate alveolar bone loss not exceeding 1/3 of the normal alveolar bone height (group 3), severe alveolar bone loss ranging between 1/3 and 2/3 of the normal alveolar bone height (group 4), or alveolar bone loss exceeding 2/3 of the normal bone height and angular bony defects and/or furcation defects (group 5). During these 20 years, the number of individuals in groups 1 and 2 increased from 49% in 1973 to 60% in 1993. In addition, there was a decrease in the number of individuals in group 3, the group with moderate periodontal bone loss. Groups 4 and 5 comprised 13% of the population and showed no change in general between 1983 and 1993. The individuals comprising these groups in 1993, however, had more teeth than those who comprised these groups in 1983; on the average, the individuals in disease group 4 had 4 more teeth and those in disease group 5, 2 more teeth per subject. In 1973, these 2 groups were considerably smaller, probably because of wider indications for tooth extractions and fewer possibilities for periodontal care which meant that many of these individuals had become edentulous and were not placed in a group. Individuals in groups 3, 4, and 5 were subdivided according to the number of surfaces (%) with gingivitis and periodontal pockets (> or =4 mm). In 1993, 20%, 42%. and 67% of the individuals in groups 3, 4, and 5 respectively were classified as diseased and in need of periodontal therapy with >20% bleeding sites and >10% sites with periodontal pockets > or =4 mm. In conclusion, an increase in the number of individuals with no marginal bone loss and a decrease in the number of individuals with moderate alveolar bone loss can be seen. The prevalence of individuals in the severe periodontal disease groups (4, 5) was unchanged during the last 10 years; however, the number of teeth per subject increased.

Tooth loss and periodontal bone level in individuals of Jönköping County. A comparison between two adult populations living in the city and in the surrounding area.

Cross-sectional and longitudinal studies were performed in the community (in this paper changed to city) of Jönköping, Sweden, over a period of 20 years to follow changes in oral health and oral health behaviour. To widen our knowledge about dental health and dental care among the adult population, we expanded the study in 1993 to cover the whole county. The specific aim of the present study was to describe tooth loss (excluding third molars) and periodontal bone level in adult residents of Jönköping County and to compare these two parameters in adults living in the city of Jönköping with the same in adults living in the rest of the county. Random samples of individuals 30, 40, 50, 60, and 70 years old were selected. A total of 484 persons from the city and 1219 subjects from the rest of the county were examined. A total of 32 (7%) and 27 (2%) persons were completely edentulous in the examined populations from the city and from the rest of the county, respectively. A majority belonged to the older age groups, 60 and 70 years, with 17% of the subjects in the city being edentulous compared with 13% in the rest of the county. The mean number of missing teeth in subjects in the city versus subjects in the rest of the county was 0.75/0.95, 1.37/1.60, 3.34/2.43, 6.34/7.40, and 9.95/10.26 in 30-, 40-, 50-, 60-, and 70-year-olds, respectively. Of all the different tooth types, the average number of molars per person decreased the most with increasing age from an average of 7.79/7.83 (city/county) to 3.06/3.09 (city/county) for 30- and 70-year-olds, respectively. The proportion of subjects without molars was higher in the older age groups in both the city and the rest of the county with 4.8/10.7% and 15.6/22.0% of the 60- and 70-year-olds, respectively, lacking molars. In both populations, the mean periodontal bone level decreased with age. It was concluded that no important differences in tooth loss and periodontal health could be seen between the two populations. When organising dental care, dental health administrators could apply the findings from the population in the city to the entire county.

Medical status and complications in relation to periodontal disease experience in insulin-dependent diabetics.

The aim of this study was to define a population of diabetics exhibiting an increased risk of developing severe periodontitis by comparing the medical status of 2 groups of diabetics, 1 with no/minor periodontal disease and 1 with severe periodontal disease. The case-control study consisted of 2 parts, a baseline study and a follow-up study. 39 case-control pairs were selected. They were adult, long-duration, insulin-dependent diabetics matched according to sex, age and diabetes duration. One individual in each pair (the CASE) exhibited severe periodontal disease while the other (the CONTROL) exhibited gingivitis or only minor alveolar bone loss. The median age of the cases was 58 years (range 36 to 70 years) and of the controls 59 years (range 37 to 69 years). The median disease duration in cases and controls was 24 years and 25 years, respectively. The median follow-up time was 6 years. The medical variables analysed were weight, insulin dose, systolic and diastolic blood pressure, vibratory threshold, triglycerides, total-cholesterol, HDL-cholesterol, creatinine, HbA1, proteinuria, ECG, retinopathy, stroke, transient ischemic attacks (TIA), angina, myocardial infarct, heart failure, hypertension, intermittent claudication, foot ulcer, death, cause of death, and smoking habit. Biochemical analyses and clinical variables used as a routine in the monitoring of diabetics failed to differentiate between diabetics with severe and minor periodontal disease. In the follow-up study, significantly higher prevalences of proteinuria and cardiovascular complications such as stroke, TIA, angina, myocardial infarct and intermittent claudication were found in the case group. An association between renal disease, cardiovascular complications and severe periodontitis seems to exist. This indicates that a closer cooperation between the diabetologist and the dentist is necessary in monitoring the diabetic patient.

Prevalence of some oral complaints and their relation to oral health variables in an adult Swedish population.

The aim of the study was to determine, in a randomly selected 20- to 70-year-old Swedish population, the prevalence of oral burning sensations and taste disturbances and their possible correlation to salivary factors, the presence of mandibular dysfunction, the prevalence of teeth, restorative procedures, caries and periodontal disease, and smoking habits. Of a total of 533 dentate individuals, 112 reported a total of 139 symptoms. Eleven of the 40 edentulous individuals reported a total of 14 symptoms. Burning sensations were reported by 18 (3.4%) of the dentate and 1 (2.5%) of the edentulous individuals. The symptoms of pricking and burning were significantly correlated to mandibular dysfunction and negatively correlated to the number of teeth. The symptom of bad taste was correlated to the number of amalgam-filled surfaces and to cigarette smoking. No other statistically significant correlation could be found.

Incisal and occlusal tooth wear in children and adolescents in a Swedish population.

The material consisted of 527 randomly selected children and adolescents from the community of Jönköping, Sweden, who in 1983 reached the age of 3, 5, 10, 15, or 20 years. The degree of incisal or occlusal tooth wear was evaluated for each single tooth in accordance with the following criteria: score 0 = no wear or negligible wear of enamel; score 1 = obvious wear of enamel or wear through the enamel to the dentin in single spots; score 2 = wear of the dentin up to one-third of the crown height; and score 3 = wear of the dentin more than one-third of the crown height. In the age groups 3 and 5 years the primary dentition was studied, and in the age groups 10, 15, and 20 years the permanent dentition. In the 3-year-old children 63% and in the 5-year-olds 19% had no or slight incisal or occlusal wear in the primary dentition. In the permanent dentition the corresponding figures for the 10-, 15-, and 20-year-olds were 78%, 51%, and 35%, respectively. The 5-year-olds had the highest percentage of primary teeth with incisal or occlusal wear related to existing teeth in accordance with criteria 1-3 (32.2%), and the 10-year-olds had the lowest score for permanent teeth (2.5%). There were small or no differences in tooth wear between the sexes in these age groups. Eighteen children (17%) among the 5-year-olds had one or more teeth with wear scored 2 in the primary dentition, and one individual had 4 primary teeth scored 3. The corresponding figures for the 3-, 10-, 15-, and 20 year-olds were 2%, 1%, 7% and 6%, respectively. No permanent teeth with wear scored 3 were found in these age groups. The number of teeth with incisal or occlusal wear increased with age both in the primary and in the permanent dentition.
