Objectives: Generally, anterior teeth are vulnerable to traumatic injury. This such a case a patient can also suffer from an uncomplicated crown fracture. The anterior dentition requires highly esthetic results. In this point of view, when it is possible, fragment reattachment appears to be the most conservative approach and allows the maintenance of natural dental structures. This case report describes a case of an uncomplicated crown fracture of the maxillary left central incisor (tooth #21), treated with fragment reattachment.
Methods: A 28-year-old male visited the dental hospital with the chief complaint of ‘upper anterior tooth was broken and it’s too sensitive to cold water.’ This patient brought the fractured tooth fragment contained in a saline solution bottle. As a result of oral examination, the maxillary left central incisor (tooth #21, FDI) demonstrated a crown fracture without pulp exposure. But the fractured tooth surface appeared pink due to shallow dentin layer. Therefore, an indirect pulp capping was needed. After cleansing the surface, a resin-modified calcium silicate liner (TheraCal LC, BISCO) was applied on the reddish spot. Tooth fragment was given a groove for the adhesive resin space and a 2mm wide bevel for esthetic reason. The tooth and fragment was treated with etching, universal adhesive (All-bond universal, BISCO) and the two parts were linked with dual cure resin (Duolink, BISCO), under light curing; then excess was removed and superficial areas were additionally filled with packable composite resin (Filtek Z350, 3M).
Results: At the 3-month follow-up, the maxillary central incisor showed satisfying esthetics and function. The chief complaint was also solved and the pulp vitality of was maintained.
Conclusion: Fragment reattachment is the most conservative and esthetic method for traumatized tooth.
