Prevalence and Characteristics of crown fractures in permanent upper incisors from schoolchildren in a southern Brazilian city
Keywords:
Dental trauma, Tooth injuries, Permanent teethAbstract
The main goal of this study is to assess the prevalence of crown fractures in permanent upper incisors of school children using a photographic method. 227 children were photographed. Of the 889 teeth examined, 8.4% of them presented some coronal fracture. Coronal fractures due to dental trauma were most prevalent in permanent upper incisors and more frequent in boys than in girls. Most of the fractures affected only the enamel and did not need restorative procedure.
