Objective: The aim of the study was to compare the effect of submucosal injection of dexamethasone and triamcinolone acetonide on postoperative pain, swelling, and trismus occurring after impacted mandibular third molar surgery. Method and Materials: A total of 78 patients (aged 18 to 35) with asymptomatic, unilateral, impacted mandibular third molar, and without any systemic disease were included in this study. Patients were divided into three groups randomly (control, dexamethasone, and triamcinolone acetonide). In the experimental groups, dexamethasone and triamcinolone acetonide were injected into submucosa at about 1 cm above the surgical area submucosally. The control group of patients did not take any drug submucosally but the same surgical procedure was applied. Pain evaluation was performed by visual analog scale (VAS). Swelling was measured using a flexible standard ruler measuring the dimensions of the axes between certain points on the face. For trismus evaluation, maximum mouth opening was measured. Measurements taken on the preoperative, and on postoperative first, third, and seventh days were compared with each other and statistically evaluated. Results: There were statistically significant differences between the control and experimental groups on the different days of the postoperative period. The effect of triamcinolone acetonide on pain started on the first day postoperatively and the effect of triamcinolone acetonide on trismus and pain was better than other groups at the third and seventh days. However, there was no statistically significant difference between the effects of dexamethasone and triamcinolone acetonide regarding postoperative complications. Conclusion: The submucosal injection of dexamethasone or triamcinolone acetonide might be an effective treatment for postoperative discomfort occurring following impacted mandibular third molar surgery, and triamcinolone acetonide could be applied as an alternative to dexamethasone.

Paramolars are rare supernumerary molars occurring buccally or lingually/palatally near the molar row. They may cause complications such as caries, periodontal disease and delay or prevention eruption of permanent teeth. Reports of bilateral entity are rarely found in the dental literature. The present article reports a rare case of bilateral double paramolars in the maxillary molar region in 21-year-old male patient. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to evaluate the effects of melatonin (MLT) and paricalcitol (PRC) on the healing of the extraction socket following tooth extraction in rats with cyclosporine-A (CsA)., Material and Methods: 76 male Wistar rats were divided into five different groups, one of which was a control (C) group. All groups other than the control group were applied CsA (10 mg/kg/daily) intraperitoneally 7 days before the tooth extraction. The left upper incisors were extracted on day 8 and CsA injections were continued in all groups until sacrification. Starting from the day of tooth extraction, in group 1 (CsA) were given CsA, in group 2 (CsA+MLT) were applied intraperitoneal MLT injection in a dose of 4 mg/kg, in group 3 (CsA+PRC) were applied intraperitoneal PRC injection in a dose of 200 ng/kg, and in group 4 (CsA+MLT+PRC) were applied intraperitoneal PRC injection and intraperitoneal MLT until the day of sacrification of all groups. The subjects were sacrificed on day 7 and 14 following tooth extraction. For histopathological examination, the subjects stained Hemotoxylin-Eosin and evaluated histologically under the light microscope. The intensity of inflammation in extraction socket was scored based on a four-grade system., Results: The level of inflammation was found to be lower in group C on day 7, while the inflammation value was found to be higher in the group 1 on day 14 (p>0.05). Statistically significant differences were found in the ossification values on day 7 between the groups(p<0.05). The percentage of ossification on day 7 was significantly lower in the group 1 than in the C and group 3, and significantly lower in the group 2 than in the group 3. The percentage of ossification on day 14 in the group 1 was significantly lower than in group C (p<0.05)., Conclusions: CsA has a negative effect on bone healing. The application of MLT and PRC following the toxicity produced by CsA was found to positively affect the healing of the socket that develops after tooth extraction.

Odontomas are the most common odontogenic tumors, representing 70% of all odontogenic tumors. They may present in two specific forms; compound odontoma forms multiple small tooth-like structures, while complex odontoma forms an amorphous calcified mass. In this report, we present a 27-year-old male patient with multiple compound odontoma occupied regions at his jaws. The odontomas involve both alveolar and basal processes of the maxilla and mandible as well as both maxillary sinuses. Converse to conventional recommended treatment, which is surgical excision of the lesion, the management was removal of the lesion and clinical-radiologic followup. The first year's follow-up findings are presented in this case report.

AIM. This study aimed to clarify the relation between the angulation of the curved osteotome and fracture of the pterygoid plate during Le Fort I osteotomy. MATERIAL AND METHODS. Twenty-one specimens of hemisectioned Turkish skulls were used for the study. The maxilla was sectioned transversely on the floor of the pyriform aperture and posteriorly to the lateral pterygoid plate with a mechanical saw. The pterygomaxillary junction was separated with a curved osteotome by angulating the osteotome with, 0° and -30° to the occlusal plane. The undesired fractures of the lateral pterygoid plate were determined. Among 21 specimens, 7 pterygomaxillary junctions were separated with an angle of +30° , 7 with 0° and 7 with -30° to the occlusal plane. RESULTS. In group +30°, the undesired fracture occured in 6 of the cases. In group -30°, the undesired fracture was determines in one case. In cases where the separation was performed by placing the osteotome paralell to the occlusal plane all plates remained safe. CONCLUSION. Within the limited knowledge of the current study it can be concluded that the osteotome should be placed paralell to the occlusal plane.

The keratocystic odontogenic tumour (KCOT) is a relatively common oral and maxillofacial lesion that derives from remnants of the dental lamina. It is aggressive, grows rapidly and invades the surrounding tissues. Various treatment modalities and differing recurrence rates have been reported for KCOT. In order to treat a 24-year-old male patient with KCOT the first stage was marsupialisation. This was followed six months later by enucleation with the application of Carnoy's solution. The defect was filled completely with newly formed bone tissue after two years. This case shows that a large KCOT can be treated with a combination of conservative and aggressive methods.

Extraction of deeply impacted wisdom molars from the lower jaw with the bone osteotomy may necessitate removal of extra bone and complicate the procedure with damage to the inferior alveolar nerve and iatrogenic fractures of the mandible. In such cases, the sagittal split osteotomy offers excellent exposure to the operative field and minimizes bone loss at the mandibular ramus. The presented case includes removal of a deeply impacted lower third molar presenting mild infection from the mid-ramus using the sagittal split of the mandible. The sagittal split osteotomy, which appears to be a reliable technique, should be the method of preference when lower molars are deeply positioned between buccal and lingual cortices.
