Treatment of mandibular odontogenic keratocysts.

OBJECTIVE The purpose of this study was to report our experience with surgical treatment of 31 mandibular odontogenic keratocysts, with special reference to their recurrence, and to review the literature on this subject. STUDY DESIGN A retrospective analysis was conducted of all odontogenic cysts treated in the Department of Oral Surgery and Oral Medicine at Jordan University of Science and Technology between 1989 and 1995. Of a total of 227 odontogenic cysts, 31 odontogenic keratocysts were histopathologically diagnosed preoperatively. They were surgically treated through an intraoral approach by resection without continuity defects. The lower border of the mandible and/or the posterior border of the ramus was left intact. In cases where teeth were in continuity with the lesion, they were extracted. In cases where cortical perforation occurred, any associated overlying mucoperiosteum was excised. All patients were reviewed annually for a follow-up period of 2 to 8 years. RESULTS All odontogenic keratocysts were found in the mandible. Of these, 23 were in the ramus and angular region (74.2%) and 8 were located in the body of the mandible. No recurrences of the operated odontogenic keratocysts were observed during the follow-up period. CONCLUSION Our findings indicate that removal of odontogenic keratocysts by resection without continuity defects is a satisfactory method of treatment.

Aneurysmal bone cysts of the maxilla: a clinicopathologic review.

PURPOSE This study evaluated the significant differences in clinicopathologic features of aneurysmal bone cyst in the maxilla and mandible. MATERIALS AND METHODS A search of the literature showed 30 recorded maxillary cases, and these together with one previously unrecorded case formed the basis of the study. RESULTS There were no differences in the age and sex incidence. Only two patients complained of pain, and no patient complained of tenderness. No patient gave a history of trauma. Swelling was present in virtually every patient. In seven cases, there was tooth mobility or migration of teeth. Two patients complained of paresthesia. Four patients presented with proptosis, two of whom complained of diplopia. The radiographic appearance of the aneurysmal bone cyst is suggestive but not diagnostic. CONCLUSION Although these differences do not enable the clinician to make a definitive diagnosis before biopsy, they have important implications for management.

Attitude toward oral biopsy among general dental practitioners: Awareness and practice

Aims: The aim of this study was to investigate the theoretical and practical skill levels of the general dental practitioners (GDPs) toward oral biopsy and to compare these results with other developed countries. Materials and Methods: A total of 500 Jordanian GDP from the 12 major governances of the Hashemite Kingdom of Jordan were conveniently sampled and included in this cross-sectional study. Participants were asked to complete a self-reported questionnaire that was specially designed to achieve the aims and objectives of this study. Results: Results demonstrated that a significant difference exists between the perceived theoretical knowledge related to oral biopsy and the clinical practical application of this knowledge among the participant dentists. Although 93.8% of the participants claim to have the ability to diagnose oral mucosal lesions, 91.4% recognize the diagnostic importance of oral biopsy and 67% know the indications of performing an oral biopsy, only 30.7% consider the oral biopsy as a diagnostic method to be used to reach a diagnosis of an oral mucosal lesion. Conclusions: A significant difference present between the theoretical information related to oral biopsy and the practical application of this information among the GDP.
