Objectives: To compare the three non-steroidal anti-inflammatory agents (NSAIDs) diclofenac potassium, etodolac and naproxen sodium in relation to pain, swelling and trismus following impacted third molar surgery. Study Design: The study was a randomized and a double-blinded study which included 42 healthy young individuals with impacted third molars and bone retention. Patients were randomly assigned to 3 groups (n: 14) to which diclofenac potassium, naproxen sodium and etodolac were administered orally an hour before the operation. Impacted third molars were surgically extracted with local anaesthesia. Visual analog scales (VAS) were used to assess the pain in the 6th, 12th hours and on the 1st, 2nd, 3rd, 5th, and 7th days postoperatively. Swelling was evaluated using ultrasound (US) and mouth opening (trismus) was measured with a composing stick pre and post operatively on the 2nd and 7th days respectively. Results: Regarding pain alleviation, diclofenac potassium was better than naproxen sodium and naproxen sodium was better than etodolac but these differences were not statistically significant. US measurements showed that the swelling on postoperative 2nd day was significantly lowest with diclofenac potassium as compared to others (p= 0.027) while naproxen sodium and etodolac acted similarly (p=0.747). No difference was noted regarding trismus in any of the groups. Conclusions: NSAIDs (diclofenac, naproxen and etodolac) are somehow similarly effective for controlling pain and trismus following extraction of mandibular third molars but diclofenac potassium surpasses others in reduction of swelling. Key words:Diclofenac potassium, naproxen sodium, etodolac, impacted third molar surgery, pain, swelling, trismus.

Objectives: The majority of the pathologic structures which are seen in the oral and maxillofacial region are either cystic or tend to show cystic changes. They may have not specific clinical and radiographic findings. Therefore, it is difficult to differentiate these lesions preoperatively. For this purpose, in this research, the value of fine-needle aspiration cytology (FNAC) in preoperative diagnosis was investigated by comparing with the postoperative histopathologic diagnosis. Methods: One hundred aspirates from cystic lesions in the oral and maxillofacial region were included in this study. All of the samples except one were examined histopathologically and the results were compared. Results: The results of the FNAC specimens obtained from 100 lesions were compared with histopathologic diagnosis of these lesions. According to these results, 12 insufficient (12%), 7 positive (7%), 81 negative (81%) specimens were obtained. Among these 88 lesions, 69 of them were diagnosed specifically by cytological examination (78.4%). 62 of the 69 specific diagnoses achieved by cytological examination were confirmed histopathologically (89.85%). The histological types of the seven lesions were missed by cytological examination. There were not any complications related with the fine-needle aspiration procedure in the research. Conclusions: According to these results, the value of fine-needle aspiration biopsy in cystic lesions of the maxillofacial region is found as successful as in the solid lesions.

Sagittal split ramus osteotomy (SSRO) is used for correction of numerous congenital or acquired deformities in facial region. Several techniques have been developed and used to maintain fixation and stabilisation following SSRO application. In this study, the effects of the insertion formations of the bicortical different sized screws to the stresses generated by forces were studied. Three-dimensional finite elements analysis (FEA) and static linear analysis methods were used to investigate difference which would occur in terms of forces effecting onto the screws and transmitted to bone between different application areas. No significant difference was found between 1·5- and 2-mm screws used in SSRO fixation. Besides, it was found that 'inverted L' application was more successful compared to the others and that was followed by 'L' and 'linear' formations which showed close rates to each other. Few studies have investigated the effect of thickness and application areas of bicortical screws. This study was performed on both advanced and regressed jaws positions.

A 6-year-old girl with hemifacial microsomia was examined. Abnormalities found were: severely malformed pinna of the right ear, right malar hypoplasia and unilateral mandibular hypoplasia. Dental examination revealed normal intraoral soft tissues with all deciduous teeth present. Radiographic examination disclosed that the maxillary and mandibular right and left second premolars were not developing. The mandibular ramus was short in length and the mandibular condyle had not developed on the right. The patient had no renal, cardiac or skeletal anomalies and her hearing was normal. No previous publications have been located which report the association of hypodontia and hemifacial microsomia.
