Almost, 50% of the mandibular fractures occur in the teeth bearing region.</p><p>A common problem in managing mandibular fracture involves dealing with teeth in the line of fracture. Commonly, there are impacted wisdom teeth associated with mandibular angle fractures. However, any fracture involving the dentate areas of the jaw has the potential to involve erupted teeth in the fracture line.</p><p>The fracture line with involved teeth communicates through periodontal space with oral cavity, which may allow the spread of infection. Another possibility is that the blood supply of these teeth may be disturbed by trauma, and in that case causing necrosis of the pulp with subsequent infection.</p><p>In the literature, there are different attitudes and procedures of various authors regarding the tooth in mandibular fracture line. Cupar[<xref rid="ref1" ref-type="bibr">1</xref>] in 1935, in the preantibiotic era, believed that the extraction was absolutely indicated if it was a very carious tooth or retained root. The danger of infection in a compounded fracture posed severe problems in treatment. Osteomyelitis, delayed healing and nonhealing were sequelae of mandibular fractures rendering the treatment often prolonged and complicated. Ditchfield[<xref rid="ref2" ref-type="bibr">2</xref>] in 1960 agreed that disrupted periodontal ligament around tooth might represent the entrance of infection, but he considered that the empty tooth socket after extraction of such teeth is even wider communication fulfilled only with blood clot. Rowe and Killey[<xref rid="ref3" ref-type="bibr">3</xref>] in 1968 believed that the tooth in the fracture line should be removed only if there was suspicion that it was not vital. Later, in the literature we could find the discussion that even such a devitalized tooth should be kept if needed for fixation.</p><p>In the recent years, the management of teeth in the line of mandibular fracture has become more and more conservative. Use of antimicrobial drugs has made infection control possible so that the prophylactic removal of the tooth in the fracture line became unnecessary.</p><p>Tooth should be kept in fracture line if its role in stabilising bone fragments exceeds the possibility of development of inflammatory complications. Criteria for the decision should be the mobility of the teeth in the fracture line, associated fracture of the tooth root, periapical lesions and the role of the teeth in mandibular fracture line in the stabilization and fixation of bone fragments. The current evidences presented by researchers all over the world seem to be overwhelmingly in the support of conservative management of such teeth.</p><p>The aim of this study was to evaluate teeth involved in the line of fracture, clinically and radiographically, and their associated complications so as to indicate if they should be managed conservatively or extracted.</p><sec sec-type="materials|methods" id="sec1-1"><title>Materials and Methods</title><p>This study included 25 patients of both sexes with mandibular fractures in the age group of 18-48 years, presenting no medical contra indications for the planned procedure. Detailed history of the patients was recorded in standardized format. Data collected from the patients included pre and postoperative panoramic radiographs, age at the time of injury, sex, and site of madibular fracture.</p><p>The sites of fractures in the mandible consisted symphysis, parasymphysis, body, and angle and excluded condylar fractures, all of which were treated with open reduction and internal fixation with conventional stainless steel miniplates (2 and 2.5 mm, 4 and 6 holes plates). The patients were clinically and radiologically evaluated during preoperative, immediate postoperative, 6 weeks postoperative and during regular follow-ups.</p><p>All the patients were administered intravenous ampicillin 500 mg, metronidazole 400 mg, and intramuscular diclofenac sodium 50 mg postoperatively, which varied between 5 and 7 days. They were also prescribed an antiseptic chlorhexidine mouthwash for a week's time.</p><p>The following clinical parameters were used:</p><p><list list-type="order"><list-item><p>Mobility of the tooth involved in the fracture</p></list-item><list-item><p>Vitality of the tooth involved in the fracture.</p></list-item></list></p><p>The following radiological parameter was used:</p><p><list list-type="order"><list-item><p>Teeth stabilizing the fracture segment.</p></list-item></list></p></sec><sec sec-type="results" id="sec1-2"><title>Results</title><p>Males had 96% of mandibular fractures than females with 4%.

Its prominence and position in the skeletal face predispose to frequent traumas. Some studies[<xref rid="ref5" ref-type="bibr">5</xref>] have demonstrated that it is really common to observe teeth in the line of fractures. Others authors[<xref rid="ref6" ref-type="bibr">6</xref>] mentioned that the presence of the teeth can be one of the determinant factor of the fracture location.</p><p>The management of teeth in the line of fracture had changed within the past years. In the past, it was thought that teeth in the line of fractures should be immediately removed.[<xref rid="ref7" ref-type="bibr">7</xref>] Although recent studies support the vision that non infected teeth in the line of fracture can be preserved.[<xref rid="ref5" ref-type="bibr">5</xref>]</p><p>This study demonstrated that in 16 patients the vitality of the teeth in the line of fracture with Grade I and II mobility was gradually improved and where as in 9 patients the teeth in the line of fracture remained non vital and out of which 5 pts showed signs of infection due to Grade III mobility which had to be extracted to prevent further complications.[<xref rid="ref6" ref-type="bibr">6</xref><xref rid="ref8" ref-type="bibr">8</xref>] The rest 4 patients with nonvital teeth were subjected for endodontic treatment. Macan <italic>et al</italic>.[<xref rid="ref9" ref-type="bibr">9</xref>] in his study concluded that one third of the teeth were reinnervated within 6 weeks after injury and a year after the injury 81% were reinnervated.</p><p>The study demonstrated that 20 patients with teeth in the line of fractures favoured the treatment as they contributed in stabilizing the fractured segments. Correct repositioning of fractured fragments is made quicker and easier if the tooth in the line of fracture is conservatively managed. The teeth in the line of fracture provided occlusal reference and posterior stop. They have a stabilizing effect and do not impede bone healing.[<xref rid="ref10" ref-type="bibr">10</xref><xref rid="ref11" ref-type="bibr">11</xref>] If extracted, they increase the risk of fracture contamination and may sometimes be difficult to suture.[<xref rid="ref4" ref-type="bibr">4</xref>] Neal <italic>et al</italic>.[<xref rid="ref5" ref-type="bibr">5</xref>] study supports the vision that noninfected teeth in the line of fracture can be preserved. The maintenance of these teeth can favour the treatment in some cases; therefore they contribute for the stability of the fracture. Its removal can be harmful, once that can diminish the contact between fragments, cause additional trauma to the region, increase the risk of contamination of the fracture through the empty alveolus, convert a closed fracture into an open fracture and cause the loss of the bony bunch in the zone of tension. Each case must be evaluated individually, for maintaining or not the teeth in the fracture line, depending on the clinical and radiographic findings.[<xref rid="ref12" ref-type="bibr">12</xref>]</p><p>It is generally accepted by most surgeons that antibiotic therapy should be administered when teeth are left in the line of fracture because of open nature and contamination of the oral cavity.[<xref rid="ref13" ref-type="bibr">13</xref>] Conservative treatment of teeth involved in the line of mandibular fractures has a favourable prognosis, especially if optimal reduction of the jaw fragments is achieved.</p></sec><sec sec-type="conclusion" id="sec1-5"><title>Conclusion</title><p>The study demonstrated that the teeth presence in the line of mandibular fracture is not a limiting factor for the treatment. Teeth associated with mandibular fracture should not be removed on a prophylactic basis to reduce the risk of infection of fracture sites just if there is an absolute indication for removal and when retained, they should be followed-up clinically and radiographically for at least 1 year with a view to endodontic treatment if indicated. Patients with teeth in the fracture line showing no response on pulp vitality testing should be advised extraction to avoid further complications. Despite the risk of rate of complications, tooth in the fracture line should be preserved for its merits. A regular follow-up both clinical and radiological should be mandatory for at least a period of 1 year. Each case must be evaluated individually, for maintaining or not the teeth in the fracture line, depending on the clinical and radiographic findings. As our sample size consisted of only 25 patients, a larger sample size with long-term follow-up can better evaluate the teeth in the line of fracture.</p></sec></body><back><fn-group><fn
