Effects of Le Fort I Osteotomy on Maxillary Anterior Teeth: A 5-Year Follow Up of 42 Cases

Aim: The aim of this study was to assess the vitality of maxillary anterior teeth following Le Fort I osteotomy. Materials and Methods: A total of 245 maxillary anterior teeth in 42 patients were examined by several pulp vitality tests before surgery and 1 to 5 years postoperatively. Data were recor...

description Aim: The aim of this study was to assess the vitality of maxillary anterior teeth following Le Fort I osteotomy. Materials and Methods: A total of 245 maxillary anterior teeth in 42 patients were examined by several pulp vitality tests before surgery and 1 to 5 years postoperatively. Data were recorded in SPSS and were statistically analyzed by using Pearson, χ(2), and Fisher exact tests. Results: This study showed a significant number (91%) of the maxillary anterior teeth to be sensitive to cold, 88.8% to electrical pulp test, and 89.4% to heat tests 12 months to 5 years following Le Fort I osteotomy. A total of 8 teeth (3.2%) had undergone root canal therapy (RCT) because they were nonvital and had developed apical lesions. Pain on percussion was observed in 5.7% of the teeth. External resorption was significantly associated with insensitivity (P < .05). Orthodontic therapy adds to this especially if excessive force is applied. Conclusion: A significant number of teeth had sensitivity after Le Fort I osteotomy. Only 3.2% needed RCT. When all vitality tests were negative, we used periapical radiolucency as the main criterion for judging pulp necrosis requiring RCT. It should be stressed that the outcomes of a single test cannot be considered as a reliable indicator for the presence or absence of pulpal or periapical disease or for RCT. Although the complications following Le Fort I osteotomy are few, follow-up is mandatory.
