Objective: To determine the pattern and presentations of odontogenic jaw cysts in patients reporting at the Armed Forces Institute of Dentistry. Study Design: Descriptive study. Place and Duration of Study: Armed Forces Institute of Dentistry, from Jan to Dec 2007. Material and Methods: Hundred patients including 70 males and 30 females with the age range 5-65 years were included in the study. History, clinical examination, radiographic examination and histopathologic examination of lesion were carried out for each patient. A proforma was filled for each patient for all relevant information, presentation and pattern. Diagnosis was confirmed by histopathology. Data were analyzed using SPSS version 10. Results: Out of total 100 patients, 58% were diagnosed with radicular cysts, 25% with dentigerous cysts, 15% with odontogenic keratocyst, 1% patient with calcifying epithelial odontogenic cyst and 1% patient was diagnosed with eruption cyst. Conclusion: The study demonstrates that radicular cyst was the most common odontogenic cysts followed by dentigerous and odontogenic keratocysts respectively in our study sample.

Objective: To compare the post-operative complications for mandibular fractures with three different treatment options i.e. miniplate fixation without maxillomandibular fixation (MMF), maxillomandibular fixation exclusively and maxillomandibular fixation with non-rigid fixation. Study Design: Randomized controlled trial (RCT). Place and Duration of Study: Oral and maxillofacial surgery department, Armed Forces Institute of Dentistry, Rawalpindi, Pakistan from February 2007 to January 2008. Subjects and Methods: The study was carried out over a period of one year on 90 patients with mandibular fractures. They were randomly divided into three equal groups for three treatment options. At different levels of their post-operative visit, these patients were evaluated for post-operative complications. Data were entered and analyzed in SPSS version 10. Results: Patients treated by MMF had fewer complications, 3 (10%) as compared to patients treated by miniplate without MMF or non-rigid fixation with MMF, 16.7% (5) in each group. Statistically difference was not significant (p-value =0.138). Conclusion: The occurrence of post-operative complications in the treatment of mandibular fractures is fundamentally related to the severity of the fracture rather than the type of treatment used.
