fracture pattern of maxillary incisors in children and adolescence: a new morphological classification

ABSTRACT

Traumatic dental injuries are frequent in the maxillary anterior teeth for variety of reasons like falling down in street or school, collision and sports. Many local occlusal factors such as increased overjet and general factors such as increased activity may predispose and modify these traumatic injuries. Many studies have attempted to classify the types of traumatic dental injuries based on the extent of the tooth structure involvement and the severity of the trauma. Central incisors act as one unified segment during traumatic injuries and do fracture always in certain repeated morphological patterns every time they are subjected to impact trauma. One hundred and forty [140] children were examined at their first presentation in the restorative-pe-diatric dentistry department and data was collected from new dental traumatic injuries in order to classify these morphological patterns of trauma and see which of them are happening more than others and their relationship with overjet. Data revealed that there were repeated fracture patterns which can be divided into seven morphological categories and increased overjet was more predisposeing factor
