    Objetivo: Evaluar la frecuencia y distribuci贸n de maloclusi贸n dental y su asociaci贸n con la edad, sexo y escuela de procedencia. Material y M茅todos. Se llev贸 a cabo un estudio epidemiol贸gico de car谩cter descriptivo, transversal y prolectivo, en el cual fueron examinados 399 escolares entre ocho y once a帽os previa autorizaci贸n de sus padres. La calibraci贸n del examinador se realiz贸 para minimizar la variabilidad intra examinador y se observ贸 un coeficiente de kappa de 0,997 para la valoraci贸n del tipo de oclusi贸n de acuerdo a los criterios de Angle, Dewey y Anderson, valor que refleja un alto grado de confiabilidad. Resultados. El 75.7% mostr贸 alg煤n tipo de maloclusi贸n dental, no mostrando asociaci贸n alguna con la edad, el sexo o la escuela de procedencia. La Clase I de acuerdo con Dewey-Anderson los tipos 1 y 2 fueron los m谩s presentes. Conclusi贸n. Se observ贸 la posibilidad de que el nivel educativo sobre la maloclusi贸n dental sea un factor m谩s determinante en comparaci贸n con el poder adquisitivo de las familias de los ni帽os, como factor de riesgo para desarrollar cualquier tipo de maloclusi贸n dental. Objective: This paper focuses on evaluating the frequency and distribution of dental malocclusion and its association with age, sex, and school of origin. Material and Methods: A cross-sectional study was carried out on a sample of 399 schoolchildren between eight and eleven years old, and they were examined with the prior authorization of their parents. The examiner's calibration was performed to minimize intra-examiner variability. A kappa coefficient of 0.997 was observed for the assessment of the type of occlusion according to the criteria of Angle, Dewey and Anderson, which is a value that reflects a high degree of reliability. Results: 75.7% presented some type of dental malocclusion, showing no association with age, sex, or school of origin. Class I according to Dewey-Anderson types 1 and 2 were mostly present. Conclusion: In conclusion, it was observed that the educational level on dental malocclusion is a more decisive factor compared to the purchasing power of children's families. This, however, is considered as a risk factor for the development of some type of dental malocclusion

    Aim: To determine frequency and distribution of temporomandibular disorders (TMD) by age and sex in a group of elderly adults in Mexico City.聽 Material and methods: One hundred and fifty-four older adults in Mexico City were examined in a cross-sectional study. Subjects who had big edentulous gaps (absence of two or more teeth) or those who were fully edentulous, as well as those who refused to participate, were excluded from the study.聽 For the epidemiological survey, diagnostic criteria for Temporomandibular Disorders (DC/TMD), after standardization by a dentist (kappa=0.892), were considered. Results. A 33.1% had some type of TMD, being more common in people between 60 and 69 years old, variable with which it was related (Likelihood Ratio=21.553, p=0.006, X2MH=08.389, p=0.021). A 14.3% reported some type of facial trauma history, behavior that also was statistically significant (X2MH=13.566, p= 0.0001). Disorders that occurred most frequently were: disc displacement with reduction (62.8%) and disc displacement without reduction (9.8%). Conclusions. TMD occurred in one of every three subjects surveyed, showing a relationship with age and trauma history.Objetivo. Determinar la frecuencia y distribuci贸n de los trastornos temporomandibulares (TTM) por edad y sexo en un grupo de adultos mayores de la Ciudad de M茅xico. Material y m茅todos. Estudio de corte transversal. Se examinaron 154 adultos mayores de la Ciudad de M茅xico. Fueron excluidos del estudio a todos aquellos que presentaron brechas ed茅ntulas amplias (ausencia de dos 贸 m谩s dientes) o edentulismo total, as铆 como aquellos que no aceptaron participar en el estudio. Para la encuesta epidemiol贸gica se tomaron en cuenta los Criterios Diagn贸sticos de los Trastornos Temporomandibulares (CD/TTM), previa estandarizaci贸n de una Cirujana Dentista (kappa=0.892). Resultados. El 33.1% present贸 alg煤n tipo de TTM, siendo m谩s frecuente en personas entre 60 y 69 a帽os variable con la cual estuvo relacionada (Raz贸n de verosimilitud=21.553, p=0.006, X2MH=08.389, p=0.021). El 14.3% refiri贸 alg煤n tipo de antecedente traum谩tico facial, comportamiento que tambi茅n result贸 ser estad铆sticamente significativo (X2MH=13.566, p=0.0001). Los trastornos que se presentaron con mayor frecuencia fueron: el desplazamiento del disco con reducci贸n (62.8%) y el desplazamiento del disco sin reducci贸n (9.8%). Conclusiones. Los TTM se presentaron en uno de cada tres adultos mayores examinados, existiendo una relaci贸n con la edad y los antecedentes traum谩ticos
