- OBJECTIVE: To study the association between type of restoration and apical periodontitis (AP) in root filled teeth. MATERIALS AND METHODS: The present study used data from surveys conducted in 1983, 1993 and 2003. In 1983, 130 randomly selected subjects aged 3-80 years in the city of Jönköping, Sweden, were invited for a clinical and radiological examination. The study was repeated in 1993 and 2003. New participants were, thus, recruited with the same sampling criteria and sample size in the same geographical area in 1993 and 2003, respectively. In the present study, only dentate individuals aged 20-70 years with ≥1 root filled tooth were included, yielding a sample of 788 subjects with 2634 root filled teeth. Apical periodontitis on the tooth level was the dependent variable. Periapical status was assessed according to Periapical Index (PAI). Independent variables were root filling quality, recurrent caries, type of restoration, number of teeth with apical periodontitis, age and gender. Root fillings appearing homogenous and ending within 2 mm from radiographic apex were regarded as adequate, otherwise inadequate. All radiographs were re-studied by one observer regarding periapical status and root filling quality. Risk was analyzed by means of a GEE model. RESULTS: Type of restoration, root filling quality, number of teeth with apical periodontitis within the individual and age were found to be predictors of AP in root filled teeth. Presence of recurrent caries and gender were not found to be associated with AP. CONCLUSIONS: According to the present study, root filling quality and type of restoration may be predictive of AP in root filled teeth.

- The aim of this study was to investigate the effects of the Swedish moist powder tobacco product known as "snus" on dental caries and to measure the pH fall in dental plaque. The subjects comprised male and female adults between 26 and 62 years of age (n=102), all habitual snus users for >= 10 years. The control group (n=101) consisted of similar individuals in terms of gender, age and educational level but with no tobacco use for >= 10 years. A clinical and radiographic examination and a questionnaire were completed.The pH fall after a sucrose rinse was estimated in situ in 10 randomly selected subjects per group. The salivary secretion rate was higher in snus users than non-users (2.5 vs 2.2 ml/min, p=0.005). There was no statistically significant difference regarding salivary buffer capacity. No differences were found between the two groups in terms of the plaque index, primary or secondary enamel and dentine caries, DFS and salivary counts of mutans streptococci or lactobacilli. The pH fall was somewhat more pronounced among non-users compared with snus users (NS). Snus users had a lower intake of snacks between meals and a less frequent intake of cookies (p=0.000). Furthermore, snus users had a mean gingival index (+/- SD) for the whole dentition of 20.4 +/- 18.2, while the index for non-users was14.4 +/- 13.9 (p=0.009); the corresponding values for teeth 13-23 were 14.9 +/- 20.6 and 7.7 +/- 11.9 respectively (p=0.003). To conclude, this clinical study revealed no statistically significant differences in caries prevalence between snus users and non-users and only minor differences regarding different cariesassociated factors.

- ObjectivesThis study's aim was to present data on the sociodemographic conditions, knowledge of dental diseases, dental care, and dietary habits among children aged 3, 5, 10, and 15 years in Da Nang, Vietnam.MethodsA cross-sectional epidemiological questionnaire study was conducted in a population of 840 children randomly selected by their year and month of birth (January to July), including 210 individuals in each age group. A self-reported questionnaire was completed by the parents of 3- and 5-year-olds, and a modified questionnaire was given to 10- and 15-year-olds to complete by themselves.ResultsMass media constituted the main source of oral healthcare information. Parents assisted with tooth brushing in 86 percent of 3-year-olds and 71 percent of 5-year-olds. Fluoride toothpaste was used by 44-78 percent of children, with no clear age-related trend. Within the past year, 60 percent of 3- and 5-year-olds, 20 percent of 10-year-olds, and 49 percent of 15-year-olds reported they had not visited a dental professional. Sweets were consumed between principal meals by 70-80 percent of children. Milk with sugar was regularly consumed by 71 percent of 3-year-olds and 91 percent of 5-year-olds.ConclusionsChildren showed frequent sugar consumption and insufficient frequency of brushing their teeth with fluoride toothpaste. Food-based dietary guidelines should play a significant role in nutrition and oral health. It is especially important that oral health prevention programs reach preschool children before they establish unhealthy dietary habits. Parental education about oral health and access to oral healthcare services are also needed to improve children's oral health.
