En este sentido, es de suma importancia la creación de currículos de Cariología basados en la mejores evidencias científicas disponibles, dirigidos a estudiantes de odontología como futuros odontólogos y responsables por la salud oral de las poblaciones. Algunas iniciativas han sido desarrolladas con el fin de conocer la forma de enseñanza de Cariología en diferentes facultades del mundo e incentivar la creación de consensos que logren una educación en esta área mejor estructurada e unificada (27). Sin embargo, y a pesar de que dichas iniciativas han sido desarrolladas también en América Latina, no se conoce con amplitud la forma de enseñanza de Cariologia así como tampoco existen consensos en los currículos en la región. De esta manera, durante el 17º Congreso de la Asociación Latinoamericana de Odontopediatria ALOP en São Paulo, Brasil, fue realizado el primer encuentro de profes...

Data on socio‐demographic characteristics, maternal education and oral hygiene were collected. Dental caries was defined according to the WHO criteria (cavitated lesions) and to the modified WHO criteria (active noncavitated lesions and cavitated ones). The association between community‐based fluoridation methods and dental caries was modelled using logistic (caries prevalence) and Poisson regression (DMFT). Odds ratios (OR), rate ratios (RR), and the 95% confidence intervals (CI) were estimated.ResultsA total of 1528 in Porto Alegre and 1154 in Montevideo were examin...

Las lesiones abarcan desde opacidades delimitadas blanco amarillentas o amarronadas hasta la ruptura del esmalte, siempre afectando a los primeros molares e incisivos permanentes. Por tal motivo se define esta patología con el nombre de "Molar Incisor Hipomineralization", lo que motiva el uso internacional de la sigla MIH. Se trata de una lesión de Hipomineralización del esmalte, de origen sistémico y etiología variada que se desarrolla en el primer año de vida del individuo. Se debe hacer el diagnóstico diferencial con hipoplasias del esmalte, fluorosis y amelogénesis imperfecta Las lesiones tienen un significativo impacto en las necesidades de tratamiento, incluso en poblaciones con baja actividad de caries, dificultan las técnicas adhesivas y requieren procedimientos rehabilitadores de alto costo en el adulto. La prevalencia reportada a nivel internacional varía entre 3 y 23.4%, afectando por igual a ambos sexos. En nuestro país son necesarios estudios para determinar su prevalencia.

In total, 356 adolescents answered a validated questionnaire on sociodemographic characteristics and oral health behavior and were clinically and radiographically examined for caries. The outcome was the benefit arising from radiographs for caries detection at the patient level, defined as the number of surfaces clinically classified as sound but presenting radiolucency. A total of 169 participants (47.5%) benefited from radiographs. One-third of approximal lesions were detected clinically, whereas two-thirds, mostly initial lesions, were detected radiographically only. Adolescents who reported frequent consumption of soft drinks and sugary food, those with D1MFS (noncavitated and cavitated caries experience) ≥12, D5MFS (cavitated caries experience) ≥1, clinically detected approximal lesions, and active caries were significantly more likely to benefit from radiographs (P ≤ .002). Although some indicators showed moderate-to-good sensitivity (consumption of sugary food, caries activity) or specificity (absence of clinically diagnosed approximal lesions), the accuracy of indicators evaluated (isolated or combined) never reached 0.60. The possibility of correctly identifying which adolescents would benefit from radiographs for caries detection purposes was limited in a population with high-caries experience.

A cross-sectional study was conducted with 930 pairs of 1-to-3-year-old children/parents from 10 LAC, as a complementary study of the Research Observatory for Dental Caries of the Latin American Region. The scale ECOHIS, previously tested and valid in ten countries, was applied to parents/caregivers of children to measure OHRQoL. Statistical analysis included descriptive data analysis and one-way analysis of variance (ANOVA-One-Way) were performed to compare age groups with OHRQoL. Bootstrapping procedures (1000 re-samplings; 95%CI Bca) were performed. The mean scores of the ‘Child Impact’ section in the LAC was 4.0(±8.3), in the ‘Family Impact’ section was 2.0(±4.0), and in overall ECOHIS score was 6.0(±12.0). In the ‘Child Impact’ section, Argentina 10.0(+2.4) and Venezuela 17.8(±17.5) demonstrated mean scores higher than the LAC total data. In t...

A population-based, cross-sectional survey was conducted using a representative sample of 1,136 12-year-old schoolchildren attending public and private schools. Parents answered questions on socioeconomic status and general health. Schoolchildren answered questions on dietary and oral hygiene habits. Two calibrated examiners recorded ETW on permanent teeth according to the Basic Erosive Wear Examination (BEWE) score system. Logistic regression models were performed to assess the association between the predictor variables and the prevalence of ETW (overall and severe ETW). Odds ratios (OR) and the respective 95% confidence intervals (CI) were estimated. The prevalence of ETW was 52.9%, being mild erosion (BEWE = 1) in the vast majority of cases (48.5%). Severe erosion (BEWE ≥2) was det...

An observational, cross-sectional and descriptive study was designed, considering children born from 1993-2003 who were seen in the Chairs of Comprehensive Children's Dentistry (Universidad de Buenos Aires) and of Pediatric Dentistry (Universidad de la República) and at five private dental offices between April and December 2010. Two groups were defined: A (Buenos Aires; n=1,090) and B (Montevideo; n=626). The clinical diagnosis was carried out with calibrated examiners (Kappa: 0.94) using the Mathu-Muju and Wright criteria. The prevalence of MIH was found to be 16.1% in A and 12.3% in B (p=0.03), with statistically significant differences between the public and private care sectors in both groups (A p=0.0008; B p=0.0004) and a positive correlation between MIH and year of birth (A p=0.001; B p=0.005).

Data were representative of the country as a whole. Socio-demographic information was collected with a closed questionnaire. Dental caries was assessed by clinical examination using the DMFT index. The final sample consisted of 769 participants. Mean DMFT was 15.20 and 24.12 for the 35-44 and 65-74-year age groups, respectively. Mean number of decayed teeth was 1.70 in adults and 0.66 in elders. Multivariate analyses showed higher prevalence of dental caries associated with age 65-74 years, low socioeconomic status, use of public dental services, presence of gingivitis; for decayed teeth, age 35-44 years, low socioeconomic status, use of public dental services, infrequent tooth brushing, need for oral health care, and presence of root caries showed higher severity. Uruguayan adults and elders from disadvantaged backgro...

Methods Fourteen fluoride toothpastes from four different manufacturers were analyzed. Randomized and blinded analyses were performed in duplicate for each dentifrice at the time of purchase (fresh samples) and after 12 months of storage at room temperature (aged samples). Total fluoride and total soluble fluoride concentrations were measured using a fluoride specific electrode. Results Total fluoride concentrations in all of the products were lower than the F levels specified by the manufacturers. Total soluble fluoride fractions were lower than the total fluoride concentrations in fresh samples of five toothpastes and in aged samples of ten toothpastes (p < 0.05). Three toothpastes had insufficient and unstable total soluble fluoride fractions (< 60%) and five toothpastes had only unstable total soluble fluoride ...
