Pattern of traumatic injuries to maxillary permanent incisors related to age and incisal overjet

ABSTRACT

To determine the pattern of dental trauma to maxillary permanent incisors with relation to age and overjet. A complete history and examination findings of 100 patients, aged between 7 and 17 years, presenting with trauma to permanent anterior teeth were recorded on a specifically designed proforma. Extraoral and intraoral examinations were performed and radiographs were taken when indicated. Andreasen and Andreasen's Classification [1993] was applied for the classification of dental injury, Overjet of the subjects were also recorded and classified accordingly. Hundred patients with one hundred and twenty nine traumatized teeth were observed and recorded. The average age considered was 12 years. It was noted that boys [62%], were more often involved with trauma as compared to girls [38%]. The maxillary central incisors were found to be the most affected teeth [84%], The most common cause of injuries was fall [59%]. Uncomplicated crown fracture cases were more frequently observed [31%]. Compared to patients with normal overjet, trauma was significantly higher in patients with increased overjet [P = 0.001]. Boys suffered more trauma than girls with a ratio of about 1.61. Children with increase overjet were two times more prone to dental trauma with normal overjet
