RESUMO
The purpose of this retrospective study was to analyse traumatic injuries to primary teeth in children attending an emergency dental service in a pediatric hospital in Mexico City.

The most common type of trauma was soft tissue injury, followed by luxation and avulsion. More males presented with traumatic injuries (61.8%) than females (38.2%). In both sexes, maxillary teeth received more traumatic injuries than mandibular teeth. Children 2-3 yrs old presented the highest number of injuries (195) followed by the 4-5 and 6-7 year-olds.

The pediatrician plays a very important role assisting the dental profession for the education of the parents to prevent oral disease and maintain children's oral health. This study shows the results obtained in a survey with 100 pediatricians from different institutions and universities of Mexico, in order to analyze their knowledge on basic dental care.

A total of 500 orthopantomographic X-rays of Mexican children and teenagers of either sex, aged 7-18, were studied in order to ascertain the development and calcification stages of their third molars, as well as the most frequent anomalies related with them. It was observed that the dental bud appears between ages nine and eleven, and that the third molar is absent in 32.4% of the population, with a predominance of females over males. It was also found that 7.4% of molars evidenced malposition during their early stages of development. In view of such findings, the authors consider that a diagnosis of oligodontia and malposition of the third molar, cannot be established before age 13.
