Resumen
Objetivo: Evaluar la prevalencia de traumatismos dentales (TDIs) y las demandas de tratamiento entre estudiantes de primaria. Métodos: El estudio se realizó en ocho escuelas del Distrito Federal (Brasil), con 914 alumnos de 11 a 14 años. Un operador calibrado realizó exámenes clínicos registrando edad, género, dientes afectados, causas, lugar y tipo de trauma, además del tratamiento realizado o necesario. La clasificación de O’Brien se utilizó para identificar los TDIs, y los datos fueron analizados cuantitativamente. Resultados: La prevalencia de TDIs fue del 20,24%. El diente más afectado fue el incisivo central superior derecho (37,1%). La mayoría de las lesiones fueron fracturas de esmalte (1,65%) y fracturas de esmalte y dentina sin exposición pulpar (0,31%). La edad promedio al momento del trauma fue de 10,3 (± 2,2) años. Las caídas fueron la principal causa (36,2%), y la mayoría de los accidentes ocurrió en casa (44,3%). El 18,4% de los niños reportó TDIs recurrentes. La prevalencia fue similar entre niños (20,4%) y niñas (20,0%). De los 185 niños afectados, 37 (20%) recibieron tratamiento, mientras que 148 (80%) no fueron tratados. Conclusión: La prevalencia de TDIs en la región evaluada fue alta, y los tratamientos más necesarios y realizados fueron procedimientos adhesivos.
