OBJECTIVE: The objective of this study was to assess if chlorhexidine (CHX) rinse decreases the occurrence of alveolar osteitis (AO) following third molar removal. STUDY DESIGN: A literature search identified 7 randomized prospective clinical trials reporting incidence of AO following removal of mandibular third molars. Studies were combined into 2 groups and summary relative risks were calculated for each group. One group of studies evaluated rinsing on the day of surgery only and the second group of studies rinsed at least on the day of surgery and several days after surgery. RESULTS: The relative risk for the single rinse group was 1.36 (95% confidence interval [CI] 0.80, 2.33), P>.05, whereas for the multiple rinse group, the relative risk was 1.90 (95% CI 1.46, 2.47), P<.05. CONCLUSION: Rinsing with CHX on the day of surgery and several days after may reduce the incidence of AO.

A comparative study of 2 imaging techniques for the diagnosis of condylar fractures in children.

PURPOSE: We sought to compare the sensitivity and specificity of panoramic radiographs with those of coronal computed tomography (CT) scans in the diagnosis of mandibular condylar fractures in the pediatric population. METHODS: Medical, dental, and radiographic records of patients who presented between 1995 and 2000 were evaluated for injuries involving the mandibular condyle. The sample included 22 males and 15 females with ages ranging from 2 to 15 years (mean, 8 years). Control subjects were added and matched by age and gender. The panoramic radiographs were blocked to allow separate evaluation of each condyle. Representative images from the CT scans were selected and individually photographed for projection. Both sets of images were evaluated by 4 groups of examiners: oral and maxillofacial (OMF) surgeons who regularly deal with pediatric trauma (n = 2), community OMF surgeons who had been out of training for at least 5 years (n = 6), OMF radiologists (n = 3), and OMF surgery residents (n = 6). Each image was shown for 20 seconds and the examiners were given 3 options to choose: 1) fracture, 2) no fracture, and 3) uncertain. RESULTS: The overall diagnostic accuracy of CT scanning was 90% (sensitivity, 92%; specificity, 87%), and that of panoramic radiographs was 73% (sensitivity, 70%; specificity, 77%). Of interest, the most experienced clinicians were also those most likely to respond that panoramic films were not diagnostic. Statistical analysis of the results was performed using chi(2) analysis. The differences for sensitivity measurements using the CT scan were not statistically significant (P >.1). However, the differences in sensitivity measurements using the panoramic radiographs and the specificity measurements using both the CT and panoramic radiographs were statistically significant (P <.05). CONCLUSIONS: CT scans provide consistently greater accuracy of diagnosis, sensitivity, and specificity than panoramic radiographs in the assessment of children suspected of having condylar fractures. In view of the high rate of false-negative and false-positive results associated with panoramic radiographs, coronal CT scans should be considered routine investigation in these patients.

Zygomatic exostosis.

This report describes a rare case of restricted mandibular opening caused by zygomatic exostosis and hyperplasia of the coronoid process. Computed tomography revealed the presence of a pseudojoint between the exostosis and the enlarged coronoid process; the bony restriction was surgically removed through an intraoral approach. Only 3 similar cases have been reported in the literature.
