Dental caries status of young children in a suburban community of Mexico City.

One hundred and thirty-four children, 6 to 7 yr of age from a public school in Tepepan, Mexico were examined for the prevalence and severity of dental caries. Average deft score was 6.08 and defs was 12.15. Average DMFT and DMFS scores were .57 and .99 respectively. It was observed that 66% of primary teeth with carious lesions required one surface restoration and 11% three or more surface restorations. In the permanent dentition 99% of the affected teeth required one surface restoration. A comparison of the results with those of the Mexico City public school children survey (1980) showed that the Tepepan children had a similar caries level in primary teeth and a lower caries level in permanent teeth. Although the Tepepan group showed fewer carious lesions, their caries index and unmet restorative index are still high, especially for primary dentition, so an intensive educational, preventive and restorative program is required.

[Variability and correlations of missing and decayed teeth in Sicillian adolescent grouped by age and sex].

Overall and individual tooth morbidity were assessed in relation to mouth section, age and sex in 1,761 poor Sicilian adolescents aged 14 to 20 yr with decayed teeth or teeth extracted for decay. Statistical assessment of the findings in the upper and lower arch was undertaken in a search for related differences (increases or decreases) in the number of decayed or extracted teeth in each arch. The dependence on differences between one area and another on the variables considered was also examined in terms of their statistical significance. No sex-based difference emerged. The frequency of decay or extraction was usually a function of position. Both the upper and lower right or left 6th teeth (i.e. those in the middle position) were most commonly affected in males and females. Use was thus made of Vianelli's index in determination of the statistical asymmetry of teeth decayed or extracted on either side of the 6th.

Clinical evaluation of dental and periodontal status in a group of oncological patients before chemotherapy.

OBJECTIVE: To evaluate the dental status of 88 cancer patients before chemotherapy. MATERIAL AND METHODS: Eighty-eight patients with cancer in different body locations were studied and compared with a control group. Dental plaque was assessed by means of the Silness and Löe index, dental status with the DMFT index, and periodontal status with the modified CPI index. RESULTS: In the oncological patients the mean Silness and Löe index was 1.28-/+0.11. Patients showed multiple missing teeth (mean number 7.55-/+0.80); the mean number of decayed teeth was 2.10-/+0.36; and the mean number of filled teeth was 2.27-/+0.37. As to periodontal status, the mean modified CPI index was 1.45-/+0.11. In the control group, the mean Silness and Löe index was 0.94-/+0.00. The mean number of decayed teeth was 1.21-/+0.25; the mean number of missing teeth was 4.97-/+0.67; and the mean number of filled teeth was 4.82-/+0.44. The mean modified CPI index was 1.29-/+0.10. CONCLUSIONS: Oncological patients in our study showed more dental plaque versus healthy patients and more decayed and missing teeth. However, patients in the control group showed more filled teeth than cancer patients. Periodontal status as determined by the modified CPI index was similar in both patient groups.

[A survey of dental-periodontal pathology in a sample of blind adult subjects].

The authors, after a short inquiry into the Italian epidemiological reality of blind subjects, explain the results of a study made on a sample of 105 blind adults (average age: 60.3 years) in order to check their oral health conditions. In particular, they have pointed out the DMFT index, the average number of permanent teeth present, the OHI-S index in its two components ID and IC, the CPITN index. The results of this study point is a high DMFT index, mainly owing to teeth extracted for periodontal disease. A high OHI-S index and the prevalence of the codes 2 e 3 of the CPITN index direct the therapeutical choice towards a professional oral hygiene and oral preventive protocols adequate to their sensorial deficiency.

Study of microflora in well-nourished and mal-nourished children in relation to dental caries.

Forty-five children in the age group of 2-12 years comprising 20 well-nourished (W.N.), 20 malnourished (M.N.) (both groups having DMFS of > or = 5) and 5 caries free well nourished children (control group) were studied to find out the oral microflora in these groups S. mutans was present in 55%, 20% and 0% in W.N., M.N., and control groups while S. Salivarius was isolated in 45%, 80% and 40% in the three groups respectively. There was no significant difference in the prevalence of Lactobacillus and C. albicans in the three groups. The correlation between means DMFS and the prevalence of S. mutans in W.N. and M.N. groups was highly significant (P < 0.001). Nutritional status including different grades of malnutrition had no significant bearing on the prevalence of micro-organisms isolated. The caries prevalence was higher in the W.N. group (P) while the gingival index was higher in M.N. group.

Validation of an English version of the Child-OIDP index, an oral health-related quality of life measure for children.

BACKGROUND: To evaluate the psychometric properties of the Child-OIDP for use among children in the UK and report on the prevalence of oral impacts in a sample of schoolchildren in Westminster. METHODS: Children aged 10-11 years in the final year of primary school (year 6) were selected from seven schools where annual screenings are carried out. A total of 228 children participated (99% response rate). A clinical examination was conducted followed by a questionnaire designed to measure oral health-related quality of life in children, namely the Child-OIDP. The psychometric properties of the Child-OIDP were evaluated in terms of face, content and concurrent validity in addition to internal and test-retest reliability. RESULTS: The Child-OIDP revealed excellent validity and good reliability. Weighted Kappa was 0.82. Cronbach's alpha coefficient was 0.58. The index showed significant associations with perceived oral treatment needs and perceived satisfaction with mouth and oral health status (p < 0.001). CONCLUSION: This study has demonstrated that the Child-OIDP is a valid and reliable index to be used among 10-11 year old schoolchildren in the UK.

Collaborative WHO xylitol field studies in Hungary. VII. Two-year caries incidence in 976 institutionalized children.

The aim was to assess caries increment as influenced by partial substitution of sucrose by xylitol (X group) over a 2-year period in comparison with systemic fluoride (F group) and restorative treatment only (C group). The study differed from the 3-year field study of the same series primarily in that existing base-line differences were eliminated because the protocol required that all the new subjects entering the institutions in the 1st year were to be included for a 2-year trial. During this period the number of dropouts was 243 (19.9% of all subjects), the final material consisting of 976 children (6-12 years old). The 2-year DMFS increment was 3.8 in the X group, 4.8 in the F group, and 6.0 in the C group. The corresponding ratio (RS) between caries incidence and the tooth surface population at risk was RSX, 4.5; RSF, 5.5; and RSC, 7.5. The xylitol regimen resulted in a lower increment of caries than measured in the F and C groups (p less than 0.001; convariance analysis, with base-line prevalence, number of permanent teeth, and visible plaque index as covariants.

Oral sugar clearance and other caries-related factors in patients with myotonic dystrophy.

The aim of the investigation was to try to explain why patients with myotonic dystrophy (MD) have a high caries prevalence. Seventeen MD patients, 15 of whom had been examined 8 years earlier, and 17 matched, healthy controls participated. In connection with this follow-up examination, the oral sugar clearance was evaluated after chewing a glucose tablet. A paraffin-stimulated whole saliva sample was collected for determination of secretion rate, buffer capacity, and numbers of mutans streptococci and lactobacilli. Dietary score, plaque index, oral muscular coordination, and self-cleaning ability were also recorded. For all factors, the MD patients showed less favorable mean values than the controls; the differences between the groups were statistically significant, except for the bacterial counts and the salivary buffer capacity. Thus, the high caries prevalence in MD patients may be explained by longer oral sugar clearance time, lower salivary secretion rate, higher intake frequency of sugar-containing products, higher plaque index, and less pronounced oral muscular coordination and self-cleaning ability than in healthy individuals.

Caries prevalence amongst handicapped children of South Canara district, Karnataka.

This epidemiological investigation was carried out among 524 handicapped children in the age group of 3-30 years, attending 8 different non-residential special schools in South Canara district, Karnataka. The examination procedure and criteria were those recommended by W.H.O. in 1997. The total caries prevalence was found to be 71.56%. The mean deft in the primary dentition was found to be 3.06 +/- 3.14. The mean deft and DMFT in the mixed dentition were 3.32 +/- 2.82 and 1.14 +/- 1.08 respectively. The mean DMFT in the permanent dentition was 4.51 +/- 3.17. The prevalence of dental caries was higher in the mentally subnormal and handicapped children. The decayed component constituted the majority of the dental caries index. Lack of conservative approach to the treatment had been confirmed in the study.

Relationship between dental caries experience (DMFS) and dental fluorosis in 12-year-old Puerto Ricans.

OBJECTIVES: Examine the relationship between (1) DMFS and community fluorosis index (CFI) scores, and (2) between individual DMFS and NIDR/Dean Index fluorosis scores. DESIGN: Population-based, cross-sectional study. SETTING: Public and private schools of Puerto Rico. SUBJECTS: 1435, 12-year old students. METHOD: A probabilistic stratified sample was selected from 11 regions of Puerto Rico, according to type of school (public and private), and setting (urban and rural). Children were examined using NIDR criteria for DMFS and fluorosis. Regressions examined the relationship between DMFS means and CFI scores. Individual level DMFS was regressed on NIDR/Dean Index scores to test for linear and deviation from linear trends. RESULTS: (1) There was no statistically significant relationship between regional DMFS and CFI scores, and (2) individual level fluorosis scores when dichotomized as 0-2 as the referent level to level 3-4 demonstrated a statistical significant higher DMFS with the higher fluorosis level. Gender and school setting were statistically significant in all models: females and public school attendance were associated with increased DMFS. CONCLUSION: No ecological relationship between CFI and DMFS scores was found in 12-year-old children in Puerto Rico. Moderate and severe fluorosis were associated with higher DMFS levels relative to lower fluorosis scores, though this finding may be associated with restorations placed for cosmetic reasons. While controlling severe fluorosis is desirable, this will have little impact on overall high caries in Puerto Rican children. These findings suggest caution when interpreting caries experience using the DMFS index in populations with differing fluorosis levels.

The use of an index of material deprivation to identify groups of children at risk to dental caries in County Durham.

An investigation of the potential for an index of material deprivation to indicate groups of young children at risk to dental caries and to assess caries experience in their age group at three levels of deprivation, measured by the Townsend Index, was undertaken in County Durham. Electoral wards were ranked on an index of material deprivation derived from 1991 Census data. Dental caries data for the upper quartile, inter-quartile range and lower quartile of material deprivation in the County were obtained from a dental survey of 6052 five-year-old children in 1991-92. The number of children in each group ranged from 1145 to 3058. Significant differences in dental caries experience between high, middle and low ranges of material deprivation existed. The index of material deprivation can indicate groups of children in the community at high and low risk of dental caries.

[Low caries activity and salivary pH in youngsters dialyzed for chronic renal failure].

Caries experience was studied in 18 young patients dialyzed for chronic renal failure and aged 7 to 17 years. The mean plaque index (Silness and Löe, 1964) was 1.89 +/- 0.15. Beside abundant plaque, these patients presented with poor oral hygiene and a food intake rich in sugars. Despite these unfavourable factors, caries experience was low. Of a total of 18 patients, ten (56%) had a DMF of 0. In addition, 11 subjects presented dental hypoplasias on more than two teeth. In these patients, the pH of whole saliva was determined at the beginning of the dialysis at time T and at the end of the dialysis at time To. The values at time T were always higher than those of time To. The mean pH at time T was 8.58 +/- 0.01 and the mean pH at time To was 8.09 +/- 0.01. These high salivary pH values are related to the low caries experience noted in these patients.

Oral health in non-institutionalized epileptic children with special reference to phenytoin medication.

The periodontal condition and caries experience was studied in non-institutionalized epileptic children (n = 55) who had not been subjected to any additional preventive measures. The children were distributed in a phenytoin (PHT) group with a mean age of 13.2 yr and a control group (mean age 11.8 yr) consisting of children treated with other anticonvulsants. The PHT group had a DF-s mean value of 5.4 in comparison to 7.2 in the control group. Determinations of gingival overgrowth based on the presence of gingival units with increased probing depth (greater than 4 mm) as well as the thickness of the marginal gingiva in buccolingual dimension measured on stone casts were performed. Although the plaque level and degree of gingival inflammation were similar in the two groups, 43% of the children in the PHT group showed one or more gingival units with increased probing depth (greater than 4 mm), but none in the control group. The thickness of the marginal gingiva was significantly (P less than 0.001) higher in the phenytoin-treated children compared to children who had never had phenytoin medication. In the PHT-group gingival overgrowth based on gingival units with increased probing depth was statistically significantly and positively associated with the variables gingivitis (P less than 0.05), visible plaque index (P less than 0.01), age (P less than 0.01) and years on PHT therapy (P less than 0.05).

Decision analysis in restorative dentistry.

Standardization of clinical decisions in restorative dentistry should be based on the tenets of the Hippocratic Oath. Although there is wide variability in preventive and operative treatment decisions, some of these decisions may lead along parallel courses to similar, clinically ethical outcomes. However, what parameters must be considered in judging the relative magnitude of positive and negative outcomes? This paper proposes several decision-making strategies for selecting optimum treatment plans for preventive and restorative situations. The caries-risk level of patients must first be identified in a systematic way and then it must be coupled with treatment options that are consistent with the potential future caries increment. A decision-tree approach and/or the treatment-index concept can then be applied to specific clinical conditions and preventive-restorative options to derive an "expected value" for each possible outcome.
