The purpose of this article is to analyze the attitudes of students towards the theoretical and clinical knowledge and about research as part of the Dentistry Program during their professional training at the Universidad Autónoma Metropolitana-Xochimilco. A questionnaire with Likert items was applied to students in order to know their answers about these topics. An X2 test was applied to analyze the homogeneity of answers. Results indicate that students’ opinions differ on: a) the amount of theoretical content regarding treatment (p < .003), b) some aspects regarding clinical knowledge (p < .006), and c) research options per school year (p < .05). We conclude that it is necessary to study in depth the achievements and limitations of the program proposed by the Universidad Autónoma Metropolitana-Xochimilco.
La caries de la infancia temprana (CIT) se desarrolla poco después del inicio de la erupción de los primeros dientes temporales, evoluciona rápidamente e implica un riesgo mayor de nuevas lesiones y atención de urgencias. Objetivo. Estimar la prevalencia de CIT en preescolares entre 3 y 5 años de edad, al sur de la ciudad de México. Metodología. Estudio transversal y descriptivo, con una muestra por conveniencia de niños que asistían a una escuela de educación preescolar. Se conformó por 136 infantes (82 niñas y 54 niños), previo consentimiento informado de los padres, cuya edad promedio fue de 4.3±0.8 años. El diagnóstico clínico de la CIT lo realizaron dos examinadores calibrados (Kappa 0.89, P<0.001) con criterios de la OMS. El análisis se realizó en el programa SPSS y consistió en medidas de tendencia central, dispersión y X2 (P<0.05). Resultados. La distribución de la población por género y edad no mostró diferencias significativas (P>0.124). La presencia de CIT afectó a 63.4% de niñas y 61.1% de niños sin diferencias (P=0.786). La prevalencia de CIT a los 3 años fue de 40.7%, a los 4 años de 78.9% y a los 5 años de 62% (P=0.007). Los incisivos centrales superiores tuvieron el mayor número de superficies cariadas, seguidos por los primeros molares y los dientes menos afectados fueron los laterales inferiores. La superficie oclusal/incisal fue la de mayor presencia de caries. Conclusiones. La prevalencia de CIT fue alta en esta región de la ciudad y los dientes más afectados fueron los centrales superiores. Early childhood caries (ECC) is developed a little after the beginning of the eruption of the first temporary teeth, it evolves rapidly and implicates a major risk of new lesions and urgent attention. Objective. To estimate the prevalence of ECC in pre-school students between three to five years of age, in the south of Mexico City. Methodology. Transversal and descriptive study, with a convenience sample of pre-school children. It was formed by 136 infants (82 girls and 54 boys), with previous informed consent from the parents, and whose average age was of 4.3±0.8 years. The clinical diagnose of the ECC was performed by two calibrated examiners (Kappa 0.89, P<0.001) following the WHO criteria. The analysis was made using the SPSS program with central trend measurements, dispersion and X2 (P<0.05). Results. The distribution of the population by gender and age did not show any significance differences (P>0.124). The presence of ECC affected 63.4% of the girls and 61.1% of the boys with no differences (P=0.786). The prevalence of ECC at three years of age was of 40.7%, at four of 78.9% and at five of 62% (P=0.007). The central superior incisor teeth had the highest number of surfaces with cavities, followed by the first molars, and the inferior lateral teeth were the least affected. The oclusal/incisal surface was the one that presented more cavities. Conclusions. The prevalence of ECC was high in this region of the city, and the most affected teeth were the central superior ones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
