The effect of teeth in mandibular fracture lines.

Abstract

The decision to retain or extract teeth in the line of mandibular fractures has been a subject of debate in the scientific literature, and there is a need for further evidence to clear this issue. Thus, the aim of this study was to investigate the effects on healing of teeth in the line of mandibular fractures in order to contribute to the field. The case notes of 100 patients with teeth in the line of 106 mandibular fractures were reviewed. Open reduction and rigid internal fixation (ORIF) was used if elastic intermaxillary reduction failed to achieve a satisfactory occlusion and/or anatomical reduction in the fragments as assessed by orthopantomogram (OPG) and clinical examination. The remaining cases had maxillomandibular fixation (MMF) with an arch bar and bridle wire. Three of the 106 teeth involved in the fracture lines healed with complications. In the cases where the teeth had been removed prior to fracture treatment, or in cases of delayed extractions, no complications were noted. The factors which should be considered for removal include the condition of the teeth and alveolar bone, the timing and the type of treatment. This decision should be made on an individual basis considering potential risks to avoid complications.
