Traumatize anterior teeth, dento-facial anomalies among deaf person in the middle region of Iraq

Abstract

This study was designed to determine the type and prevalence of trumatic dental
injuries, aenterio—posterior molar relation among (519) deaf persons and (532) school
students at 5-16 years of age in the middle region of Iraq. The study showed that the
prevalence of traumatic dental injuries were 6.94% for deaf persons and 5.83% for
schools students. Males showed a higher percentage of traumatized teeth than females in
institutions and school students. Enamel dentine fracture without pulp exposure was the
most predominant type among deaf persons while simple enamel fracture was the most
predominant among schools students. The majority of deaf persons and schools students
demonstrated normal type of occlusion 57.42%, 55.64% respectively. Deaf person
showed significantly with percentage of 4.62% mesial full cusp deviation from normal
.antero·postrior molar relation compared to school students 2.07%
