The purpose of this study was to assess the prevalence of dental caries, tooth loss, and risk factors among adult population of Chile. Furthermore, age, gender, and behavioural specific differences in caries prevalence and tooth loss were examined. A national stratified multistage probabilistic sample design in two-age cohorts was applied to the Chilean population. A sample of 1553 adults, comprising 1088 individuals aged 35–44 and 465 senior individuals aged 65–74, were examined. The DMFT was evaluated following WHO recommendations using diagnostic criteria of caries lesions into dentin. The data were analyzed by univariate and multivariate models using logistic regression analyses. Results showed a mean DMFT of 15.06 in the 35–44-year-old group and of 21.57 in the 65–74 group. Factors related to tooth loss in the 35–44 group through univariate logistic regression were depression (OR 1.9 CI 95% 1.26–2.85), education level <12 years (OR 2.24 CI 95% 1.31–3.73), personal income (OR 1.51 CI 95% 1.04–2.19), and familiar income (OR 2.05 CI 95% 1.34–3.13), and through multivariate logistic regression in the same age group were depression (OR 1.93 CI 95% 1.24–3.0), education level <12 years (OR 1.94 CI 95% 1.2–3.14), and familiar income (OR 1.71 CI 95% 1.09–2.68). Factors related to tooth loss in the 65–74-year-old group through univariate logistic regression were education level <12 years (OR 2.54 CI 95% 1.3–4.96) and personal income (OR 1.66 CI 95% 1.05–2.63), and for multivariate logistic regression in the same age group, it was education level <12 years (OR 2.51 CI 95% 1.21–5.18). In conclusion, adult population in Chile showed a high prevalence of dental caries and tooth loss, as age, education level, personal and familiar incomes, and depression are being the main risk factors.
The aim of this study was to compare milk supplemented with probiotic lactobacilli with standard milk for the increment of caries in preschool children after 10 mo of intervention. The study was a triple-blind, placebo-controlled randomized trial. Participants were children aged 2 and 3 y (n = 261) attending 16 nursery schools in a metropolitan region in Chile. Nursery schools were randomly assigned to 2 parallel groups: children in the intervention group were given 150 mL of milk supplemented with Lactobacillus rhamnosus SP1 (10(7) CFU/mL), while children in the control group were given standard milk. Interventions took place on weekdays for 10 mo. Data were collected through a clinical examination of participants. The primary outcome measure was the increment of caries in preschool children. This was assessed using the International Caries Detection and Assessment System (ICDAS). The dropout rate was 21%. No differences in caries prevalence were detected between the groups at baseline (P = 0.68). After 10 mo of probiotic intake, the caries prevalence was 54.4% in the probiotic group and 65.8% in the control group. The percentage of new individuals who developed cavitated lesions (ICDAS 5-6) in the control group (24.3%) was significantly higher than that in the probiotic group (9.7%). The increment of dental caries showed an odds ratio of 0.35 (P < 0.05) in favor of the probiotic group. At the cavitated lesion level, the increment of new caries lesions within the groups showed 1.13 new lesions per child in the probiotic group compared with 1.75 lesions in the control group (P < 0.05). The probiotic group showed an increment of 0.58 ± 1.17 new lesions compared with 1.08 ± 1.70 new lesions observed in the control group. The difference in caries increment was significant at the cavitated lesion level (P < 0.01). In conclusion, the regular long-term intake of probiotic-supplemented milk may reduce caries development in high-caries preschool children (ClinicalTrials.gov: NCT01648075).
Higher levels of ureolytic (statistically significant) and arginolytic activity (trend) in saliva were associated with lower DMFT/dmft scores in 8 year old children. There was a higher production of ammonia from the arginine deiminase system than the urease enzyme in saliva (p>0.05).
(año 2011), se elaboró una propuesta de currículo inicial, basado en los dominios propuestos por la Unión Europea (Schulte AG y cols). Durante el año 2016, dicha propuesta fue analizada mediante diálogos digitales y grupos de trabajo, con la participación del 96% de las Escuelas de Odontología existentes en el país, que concluyeron en un documento intermedio. Este documento fue analizado, discutido y perfeccionado durante el Taller para el Desarrollo de un Currículo de Competencias Mínimas en Cariología para las Escuelas de Odontología Chilenas (22/Mayo/

ABSTRACT:The objective of the study was to determine the association between caries prevalence and body mass index (BMI) in preschool children in Santiago, Chile. Children aged 2 and 3 years old (n = 342) attending 16 nursery schools in Santiago, Chile were examined to record the status of dental caries using the modified criteria of the International Caries Detection and Assessment System (ICDAS II) (International Caries Detection and Assessment System (ICDAS) Coordinating Committee, 2005). BMI was calculated for each of the subjects and their nutritional state was classified as underweight, normal-weight, overweight and obesity according to the WHO. The caries prevalence (ICDAS 2-6 > 0) of the children was 45.9 % (IC 95 % 40.50 -51.21). Data showed that none of the preschoolers were underweight. 39.1 % were classified as normal-weight (IC 95 % 33.98 -44.38), 34.8 % as overweight ) and 26 % as obese ). Normal-weight children had a prevalence of 51.5 % of ICDAS 2-6 lesions and prevalence of 28.3 % of ICDAS 5-6 lesions. Children with overweight had prevalence of 51.4 % ICDAS 2-6 lesions and of 19.3 % ICDAS 5-6 lesions, and obese children of 39.5 % and 25.8 % respectively. Subjects with normal-weight presented a mean of ICDAS 2-6 caries lesions significantly higher (p < 0.05) than the rest of the children. In conclusion, normal-weight preschool children presented a higher prevalence of caries lesions than those with overweight and obesity. Iso-BMI was found to be associated with lower dental caries and severity. Future studies should address which specific factors related to overweight in children might be protective against dental caries.
