Root fracture of permanent incisor with type II dentinogenesis imperfecta

Abstract

Dentinogenesis imperfecta is an autosomal dominant disease that involves incomplete calcification and irregular formation of dentine, hard tissue constructing crown and pulp chamber. The disease presents in deciduous as well as permanent teeth. Morphologically, thin root, round crown and cervical narrowness are observed and pulp chamber is small or defected. Because of these morphological characteristics, root fracture invariably occurs even with minor trauma. The prevalence of dentinogenesis imperfecta in primary dentition is reportedly higher than that of permanent dentition. Few studies have reported dentinogenesis imperfecta in permanent dentition. Although the diseased teeth are vulnerable to trauma, studies on root fracture of permanent teeth with dentinogenesis imperfecta are not often reported. We reported a case of root fracture in dentinogenesis imperfecta involved tooth and described the treatment and follow up.
