Abstract

Radicular fractures in permanent teeth are uncommon injuries and account for only 0.5–7% of dental traumas. These fractures commonly result from a horizontal impact and are transverse to oblique in direction. Their incidence is more in the middle third of the root than at the apical and cervical thirds. This paper describes a case of complicated crown fracture of maxillary incisors along with horizontal root fracture at the middle third of maxillary right central and lateral incisor. The fractured root fragments of the upper right central and lateral incisor were united with the help of a glass fiber post after receiving an endodontic treatment. The other two incisors were treated endodontically followed by post endodontic restorations. Eventually the four incisors were restored with porcelain fused to metal crowns. A one-year follow-up revealed a well stabilized assembly of the root fragments and the post.

Highlights

Among all dental traumatic injuries, root fractures account for only 0.5–7% [1,2,3]
This report thereby describes a case of horizontal root fracture with displaced fragments, which were united with the help of glass fiber posts followed by core build-up and coronal coverage
Appropriate glass fiber posts were tried into the canals, adjusted to the desired length until they just passively touched the apical gutta percha

Summary

Introduction

Among all dental traumatic injuries, root fractures account for only 0.5–7% [1,2,3]. Root fracture is defined as “fracture involving dentin, cement and pulp” [1]. Horizontal root fracture most commonly occurs in the middle third of the root and very rarely in the coronal and apical third [4]. Root fracture occurs as a consequence of an impact force on the top of the root and frontal forces affect the compression zone labially and lingually/palatally, dividing the root into coronal and apical fragments. This can traumatize the supporting periodontal tissues eventually leading to displacement of the root fragments [7]. This report thereby describes a case of horizontal root fracture with displaced fragments, which were united with the help of glass fiber posts followed by core build-up and coronal coverage
