Type of Article: Follow-up study
Main Purpose: To record the different types of trauma to permanent incisors and the prognosis
Overview of method of research : 55 patients and 84 injured incisors with incomplete root formation were included in the study. The teeth were followed over a 5 year period. The crown fractures were divided into categories 1. Fracture of enamel 2. Fracture of enamel and dentin 3. Fracture of enamel and dentin with pulp involvement. Any teeth with associated subluxation, luxation, root and/or crown-root fractures were excluded.
Findings: 8 year olds were most commonly injured. 3.6 to 1 boys/girls. 95% were maxillary central incisors. Most common injury was fracture of enamel dentin without pulpal involvement. 51% had a associated soft tissue lesion. 40% of injuries occurred in pts with overjets greater than 3mm.
Key points/Summary : All three teeth with fractured enamel had no pulp complications. Out of 67 teeth with uncomplicated fractures 4 teeth showed pulp necrosis and 1 showed pulp obliteration. Out of 14 teeth with complicated fractures 8 showed pulp necrosis. 34 (40.5%) restored teeth had to be retreated because of a new trauma.
Assessment of article: Good article although I found it somewhat confusing at times.
