title: Prognosis of teeth in the line of jaw fractures.
abstract: OBJECTIVE
  The decision as to whether teeth in the line of jaw fractures should be extracted or retained remains a controversial issue. The aim of this study was to assess the prognosis of teeth directly in the line of, and adjacent to, jaw fracture sites.
  
  
  METHODS
  The study consisted of 50 patients with facial fractures in the dentate region, the diagnosis of which was made on the basis of clinical and radiographic examinations. A total of 124 teeth were present in 69 fracture sites (50 patients), of which 89 teeth were evaluated both, clinically (tooth mobility, pocket depth, pulp sensibility) and with periapical radiographs (degree of fracture displacement, marginal bone loss, root resorption).
  
  
  RESULTS
  The results revealed that 61.9% of teeth in directly in the line of fractures showed no response to electric pulp testing compared with 48.9% teeth adjacent to fractures. The maximum frequency of non-responsive teeth was observed in Type I fractures followed by Type II fractures. Response to pulp tests was highly significant at postoperative 3- and 6-month periods (Wilcoxon's test). There was continuous reduction in the measurement for mean pocket depth at both test and control sites of teeth. The measurement of marginal bone levels of teeth in the line of fractures revealed a significant reduction (P < 0.01) from preoperative to postoperative 7-day period only. In teeth adjacent to fracture sites, the mean marginal bone levels of control site and test sites were not significant at any time interval. There was no difference in postoperative complications pertaining to whether the tooth at the fracture site was extracted or retained.
  
  
  CONCLUSIONS
  Teeth in line of jaw fractures should not be removed on a prophylactic basis and should be followed up clinically and radiographically to determine any treatment needs.
