Risk factors for dental caries in children with cerebral palsy.

This study was conducted to examine the oral condition and the salivary and microbiological parameters associated with dental caries in 62 children with cerebral palsy, who came from households of low socioeconomic status (Study Group). This group had mixed (6 to 11 years old) and permanent (11 to 16 years old) dentition. Dental examinations were performed to measure dental caries, plaque index, salivary levels of mutans streptococci and lactobacilli, salivary flow rate, pH of stimulated saliva, and buffer capacity of saliva. A group of 67 non-handicapped children from similar socioeconomic backgrounds also were examined using these parameters (Control Group). Data were analyzed statistically by non-parametric tests and by correlation. The results showed that children with cerebral palsy who had permanent dentitions had a higher mean decayed, missing and filled surfaces index, as well as a higher plaque index for both sexes. Microbiological examination revealed higher levels of mutans streptococci among Study Group subjects with mixed dentition than in the Control Group. Also, lactobacillus counts were higher in the Study Group, regardless of sex or dentition. With respect to salivary flow rate, pH and buffering capacity, lower mean values were obtained for the Study Group.

The prevalence of root caries in a diabetic population.

The objective of this study was to assess the level of root caries in a population of diabetic adults. Diabetics are of special interest because they are alleged to be periodontally compromised and have atypical patterns of refined carbohydrate ingestion. Diabetic subjects were patients of the Joslin Diabetic Center in Boston and had significantly elevated blood glucose and glycosylated hemoglobin levels over at least a ten-year period. Eligible subjects had to be between the ages of 45 and 65 and have a minimum of ten teeth and three sites with recession. Data were collected on coronal caries, oral hygiene, gingivitis, pocket depth, recession, and root caries and were compared with data from control subjects from a larger non-diabetic study group. There were 88 diabetics and 185 controls with mean ages of 55.7 and 56.3 years, respectively. The groups were found to be similar with respect to the numbers of buccal surface sites with gingival recession and the numbers of carious root lesions. There was a distinct difference, however, with respect to restored root surfaces: 1.76 mean filled surfaces were observed in the controls, as compared with 0.49 in the diabetics. A Katz Root Caries Index (for which lesions are calculated as a percentage of the numbers of exposed root surfaces) was determined to be 15.2 for the controls and 7.1 for the diabetics. A reasonable inference is that these differences are the result of a restricted ingestion of refined carbohydrates by the diabetic group. This was confirmed by a dietary survey of subsamples from the diabetic and non-diabetic groups.

Dental caries and dental registration status in nursery school children in Newry, Northern Ireland.

294 children aged 2-4 yr attending nursery schools in Northern Ireland were examined for dental caries and dental registration status under the capitation system in general dental practice. Their mean age was 3 yr 10 months. Sixty eight per cent were caries free, mean dmft was 1.10 and dt, mt and ft scores were 0.74, 0.28 and 0.09, respectively. With increasing age the prevalence of caries increased, though the very low care index (d/dmft) did improve in the older children. Seventy per cent reported being registered for dental care and their levels of dental caries were significantly higher than those who were not yet enrolled (P < 0.001). For those not enrolled for dental care the main perceived barriers to seeking care related to lack of symptoms (33.6%) and apathy (31.6%) while few reported fear as a barrier (4.5%).

[Combined valuation of the success of therapy of orthodontic anomalies, periodontal diseases and dental caries].

Using the DMF/T, GPM/T and CPITN-index systems, the numerical evaluation method according to Eismann and measuring the occlusal contact areas in static occlusion in 101 orthodontically treated adolescents and young adults the effect of complex preventive and therapeutic programs was studied. The used parameters allow to characterize oral health status. After completing the orthodontical treatment there is a need to continue preventive programmes and therapeutic interventions in adults to reach stable oral health conditions.

Dental enamel defects in celiac patients.

OBJECTIVE: The incidence and distribution of enamel defects among patients with celiac disease were examined. STUDY DESIGN: The oral cavity was explored in 137 patients with celiac disease (mean age 16.2 years; age range 5 to 68 years) and in 52 control patients (mean age 19.8 years; age range 5 to 64 years). Permanent dentition enamel defects were recorded, along with their number and locations. The decayed, missing, and filled teeth index rates were also established, and an investigation was made of the human leukocyte antigens among the patients with celiac disease. The results obtained were analyzed with the chi-squared test, statistical significance being regarded for p < or = 0.05. RESULTS: Enamel defects were observed in 72 (52.5%) of the patients with celiac disease (52 patients had systematic defects) and in 22 (42.3%) of the control patients (9 patients had systematic defects). Systematic defects were significantly more common in the celiac disease group. In the patients with celiac disease, 72.2% were symmetrical, compared with 40.9% of the defects in the control patients. The incisors were the most frequently affected teeth, the extent of involvement being significantly greater in the celiac disease group. In patients with celiac disease, DR7, DR3, and DQ2 were the most commonly observed human leukocyte antigens. The mean decayed, missing, and filled teeth index rates were 4.8 and 6.2 in the celiac disease group and the control group, respectively. CONCLUSIONS: Enamel defects are common among patients with celiac disease. They tend to be bilateral and symmetrical, and they are chronologically distributed. The lesions affect mainly the incisors and the molars. Patients with such characteristics should be evaluated for possible celiac disease.

Oral health status of adult population in Athens, Greece.

An epidemiological study of dental caries, periodontal disease, and oral hygiene status in 736 employed adults aged 19-64 yr, was conducted in Athens, Greece. Dental caries was found to be prevalent, affecting almost the entire population examined. The mean DMFT values varied from 8.99 +/- 5.98 to 17.05 +/- 6.58 in different age groups. No difference was found in the mean DMFT values between sexes. Periodontal disease affected the 92.7% of the examined sample. The PI scores increased with age from 1.08 +/- 0.84 in the age group 19-24 yr to 3.7 +/- 1.84 in the age group 55-64 yr. Women showed lower PI index values than men but this difference was not statistically significant. The mean values of oral hygiene index varied from 1.60 +/- 1.05 to 1.97 +/- 1.42 in different age groups. Women presented better oral hygiene status than men and this difference was statistically significant for the younger age groups. Data concerning the toothbrushing frequency of the examined population are also presented. The results of this baseline study indicate that effective dental care is needed for the improvement of oral health status of the adult population.

Caries and fluorosis prevalence in communities with different concentrations of fluoride in the water.

The need to defluoridate and fluoridate the water supplies in areas with drinking water naturally containing above-optimal (>/=2.5 mg/l) and suboptimal (</=0.3 mg/l) fluoride concentration and caries and fluorosis prevalence of 12-year-old schoolchildren were assessed in Italy. In the low-fluoride area, 48.4% children were caries-free (DMFT = 0) and the DMFT and DMFS were 1.5 and 2.6; in the high-fluoride area, 46.8% had a DMFT = 0 and the values of the indices were 1.4 and 1.6, respectively. Multiple logistic regression analysis showed a significant association in the caries-free status according to parents' employment status (OR = 1.2, 95% CI = 1.1-1.3) and children's sweets consumption, since children who consumed sweets at least once a day had an adjusted odds ratio of 1.8 (95% CI = 1.4-2.3) compared to those with a lower consumption. Multiple linear regression analysis showed that DMFT and DMFS were significantly higher in children with a lower socioeconomic status and in those who consumed sweets at least once a day, with the DMFS significantly associated also with the area of residence. DT and FT scores were higher in the high- and low-fluoride areas, respectively. No evidence of fluorosis was reported in 94.5 and 55.3% of children in the low- and high-fluoride areas, respectively. The Community Fluorosis Index (CFI) for all permanent teeth was significantly higher in the high-fluoride area, 0.8, than the value, 0.1, found in the low-fluoride community. Our results substantiate the difficulties in defining universal guidelines for the fluoridation or defluoridation of drinking water and the need for an epidemiological approach to the decision as to fluoridate and defluoridate the water supply.

Comparison of dietary habits and dental health of subjects with hereditary fructose intolerance and control subjects.

Persons with HFI follow a lifelong, self-imposed, sucrose-restricted diet in which foods containing sucrose are consumed infrequently. Our subjects with HFI had a total sucrose intake that was approximately 5% that of control subjects and had a caries score (DMFS) that was less than 10% that of control subjects. No significant differences were found in the oral hygiene status (plaque or oral hygiene indexes) of the two groups. Foods containing starch, in the absence of sucrose, are not articularly inducive to caries. The daily intake of sucrose of the control group was less than expected. Consumption of sucrose is, therefore, less than estimates calculated by per capita sucrose disappearance. We consider that caries is initiated when the sucrose content of the diet and the frequency of ingestion exceed a low limit.

Outcomes data made easy.

Dx Index is a quick and easy method for quantifying patients' oral health. A number scale from 1 to 10 provides an easy-to-understand assessment of the dental health status of either an individual or a large group. During routine oral examinations, areas such as decayed teeth, pocket depth, inflammation and oral hygiene are numbered by level. Reading the lowest number on a chart pertaining to these categories gives a rapid overall score of dental health.

[Correlation between dental status and dental anxiety].

The relationship between dental status and dental anxiety was analysed in 165 patients. To assess the dental status, D3.4 MFS-index and Bleeding-on-Probing-Index (BOP) were applied. Dental anxiety was assessed using dental anxiety rating, whereas aspects of state and trait anxiety were analysed by the State-Trait-Anxiety Inventory. The hypothesis was: higher levels of dental anxiety lead to avoiding check-ups and necessary treatment, the consequence of which is a deterioration of the dental status. No significant correlation was found between dental anxiety and dental status. A significant difference was found when comparing patients with high or low dental anxiety in respect of the D3.4 MFS-index, whereas a different trend was found on comparing these groups for BOP-index. In addition, a significant correlation was found between dental anxiety and trait anxiety. These results suggest that dental anxiety is a rather non-specific phenomenon, since it is an aspect of proneness to anxiety. In addition, in patients who display considerably high dental anxiety, this may lead to anxiety denial and abnormal behaviour (e.g. avoidance of dental hygiene or care) thus contributing to further deterioration of oral health.

[Prevalence of dental caries among school children: a cross-sectional survey in the city of Barcelona].

The results of a cross-sectional survey performed in the spring of 1990 in a sample of 533 twelve-year old schoolchildren in the city of Barcelona (Spain) are presented. The proportion of children with caries is 49.2%, with a DMFT index of 1.34 (1.09 for boys and 1.50 for girls). 63.4% of permanent decayed teeth were filled, and 2.2% were missing. There is a socioeconomic gradient in dental decay, with more caries among the lower socioeconomic strata, where missing teeth concentrate. The comparison of these results with those of other studies suggests a decline in caries incidence in school age in Spain, and greater use of dental care services.

Needs and implementation of preventive dentistry in China.

Based on a literature review and recent surveys, the needs and implementation of preventive dentistry in China have been estimated. The average DMFT of 12- and 15-yr-old schoolchildren in Beijing were 1.61 and 2.11 respectively. The caries prevalence was higher in the coastal cities in the south. The caries rate was also higher in urban areas than in rural areas. There were some controversies in the results of fluoridation studies with one study reporting as high as 47.2% of the children to be afflicted with enamel fluorosis. The community periodontal disease status and treatment needs index (CPTNI) showed that 93% of the 12-yr-olds had bleeding, 98% had calculus and 15% had shallow pockets, with 100% of the children needing prophylaxis. There was a high prevalence of dental malocclusion with 54% of schoolchildren with dental anomalies, of whom 36% needed treatment. Much emphasis had been placed on oral pathology, oral medicine and maxillofacial surgery in the curriculum of Stomatology in Chinese dental schools.

Validation of the Child Perceptions Questionnaire (CPQ 11-14).

While the use of adult oral-health-related quality-of-life (OHRQoL) measures in supplementing clinical indicators has increased, that for children has lagged behind, because of the difficulties of developing and validating such measures for children. This study examined the construct validity of the Child Perceptions Questionnaire (CPQ(11-14)) in a random sample of 12- and 13-year-old New Zealanders. It was hypothesized that children with more severe malocclusions or greater caries experience would have higher overall (and subscale domain) CPQ(11-14) scores. Children (N = 430) completed the CPQ(11-14) and were examined for malocclusion (Dental Aesthetic Index) and dental caries. There was a distinct gradient in mean CPQ(11-14) scores by malocclusion severity, but there were differences across the four subscales. Children in the worst 25% of the DMFS distribution had higher CPQ(11-14) scores overall and for each of the 4 subscales. The construct validity of the CPQ(11-14) appears to be acceptable.

Oral health disparities between ranks in a military environment: Israel Defense Force as a model.

UNLABELLED: Some studies have demonstrated a relationship between occupational status and position in the workplace to use of dental services and oral health status. Ranks symbolize social status in the military hierarchy, which is different from that accepted in civilian workplace. OBJECTIVE: This study was aimed at analyzing differences between officers and noncommissioned personnel in regard to dental treatment needs and use of dental services. METHODS: One-thousand, one-hundred thirty-nine personnel of the Israel Defense Force were examined, using DMFT (decayed, missing, filled permanent teeth and CPITN (community periodontal index of treatment needs indices to define oral health status. A questionnaire was used to calculate utilization rates. RESULTS: Noncommissioned personnel had on average 50% more unmet caries treatment needs, and 19.1% of them suffered from deep periodontal pockets. No differences were demonstrated in utilization rates CONCLUSIONS: Military rank influences oral treatment needs the way civilian organizational structure does with the exception of utilization rates of dental services.

Clinical evaluation of tunneled molars: a retrospective study.

BACKGROUND: The main concern associated with the tunneling procedure is the development of root caries on the furcation area post-treatment. The objective of this study was to evaluate the periodontal conditions and the prevalence of root caries in tunneled molars. METHODS: The study sample comprised 30 tunneled teeth (mean tunneling age = 3.6 years) in 18 subjects who had received periodontal treatment and were enrolled in a maintenance program that included the application of fluoride to the exposed root surfaces. Plaque index (PI), pocket depth (PD), bleeding on probing (BOP), decayed, missing, filled or sound teeth (DMFT) and demographic characteristics were assessed. Statistical analysis was performed using the Friedman and Mann-Whitney tests and multiple linear regression analyses. RESULTS: Four teeth (13.4%) showed active root caries inside the tunnels. Six (5.4%) of the 109 root surfaces facing the furcation region (inner surfaces) were affected by carious lesions, similar to the amount of root caries observed on the outer tunnel root surfaces, where 10 (5.3%) of the 189 surfaces studied were restored (p > 0.05). The interior of the tunnels had a higher percentage of sites with PD > or =6 mm then the exterior (p > 0.05). However, the plaque indexes and BOP scores were low for both the internal and external surfaces of the tunnels. Regression analysis indicated that the only positive association with the development of caries inside the tunnels was previous root caries experience (beta = -0.671; p = 0.01). CONCLUSION: The results show that tunneling is a suitable technique to treat periodontal furcation lesions in individuals following a regular maintenance program.

[Efficiency of long-term dental treatment].

250 patients in long-term treatment (about 12, 4 years) were examined concerning their oral symptoms (DMF/T, CPITN, GPM, Plaque-index, Sulcus-bleeding-index of Mühlemann and Son), number of teeth, number of extracted teeth and teeth with endodontic treatment during the treatment period. These patients were compared with 250 patients, who were not under regularly treatment. There are clear differences between both groups. It can be concluded that long-term treatment with exact fillung therapy, endodontic and periodontic treatment is able to maintain teeth until a high age of life.

The dental health of 12-year-old children in Dominica: a report of a survey using WHO methods.

As part of the process of assisting in the planning of a primary dental health care system in the Commonwealth of Dominica, we conducted a survey of mostly 12-year-old children. The purpose of the survey was to assess the oral health status and identify the needs for treatment and prevention. Secondary purposes included training Dominican dental auxiliaries and assistants to collect epidemiologic data and to use the findings to compare oral health status by region and previous coverage by the auxiliaries. The sample was obtained from schools throughout the country. Examinations were conducted according to standard WHO methods, using mirrors and explorers. The findings were recorded on prepared forms and the data were processed in Toronto using microcomputers. We found 31% of children to be caries-free and the mean DMFT score to be 2.5 (95% CI 2.2-2.7). Only 8% of lesions had been treated. No differences were observed by region but in areas covered by dental auxiliaries, children had fewer decayed teeth, fewer DMFT and higher F/DMFT ratios. Only 17% scored 0 on the CPITN index and 63% scored 2, meaning they had calculus. Debris was 3.6 times more likely to be found among those with gingival bleeding or calculus compared to those with periodontal health. Single surface restorations made up 82% of the estimated 2.0 caries treatment services required. The survey findings will allow planners to design specific preventive and treatment programs to meet Dominica's needs.

Dental caries prevalence amongst 12-year-old urban children in East Africa.

It is commonly believed that the prevalence of dental caries in developing countries is increasing, though in Kenya and Tanzania there is insufficient information to confirm such trends. In order to test the hypothesis, therefore, 762 children in Dar es Salaam and 802 children in Nairobi aged 12 yr in 1984 were examined for dental caries as part of a baseline study to monitor changes of prevalence with time. Dental caries was recorded by surfaces using the criteria recommended by the WHO and examinations were performed by standardized examiners. The mean DMFT in Dar es Salaam of 0.67 (SD 1.20) was significantly higher than that for Nairobi, 0.51 (SD 1.23). No differences were found in the mean DMFS index. Nairobi children had a greater number of filled teeth and surfaces. Although a greater proportion of children were caries-free in Nairobi than in Dar es Salaam, amongst those with caries, Nairobi children had significantly higher DMFS scores, and a greater proportion with DMFS greater than 4. The possible reasons for such findings are discussed. The mean DMFT and DMFS reported here are amongst the lowest reported in the recent literature from both countries.
