Bilateral cracked permanent first molars in dentinogenesis imperfecta type II: A case report

Abstract

Dentinogenesis imperfecta type II (DI-II) is an inherited mesodermal condition affecting the primary and permanent dentition. There is often cracking and loss of enamel and the subsequent rapid attrition of exposed dentin. This report presents a 14-year-old boy with DI-II, specifically with an unusual case of cracked bilateral maxillary and mandibular first molars. Fractures involved enamel, dentin, and cementum. to chip away from the dentine abnormally fast, leading to rapid wear and attrition of the teeth. The severity of discoloration and enamel fracturing in all DI types is highly variable, even within the same family. If left untreated, it is not uncommon to see the entire DI-affected dentition worn to the gingival 5). However, it is rare for fractures to occur in the enamel, dentin, and cementum. This paper aims to report the diagnosis and treatment of an unusual case of cracked bilateral maxillary and mandibular first molars of a 14-year-old boy with DI-II.
