Impacted tooth extraction is one of the most common operations in oral surgery. Although practitioners may encounter a variety of complications in the surgical period, mandibular fracture is rare and generally seen during third molar removal. It is reported that possible predisposing conditions include increased age, mandibular atrophy, concurrent presence of cyst or tumor, and osteoporosis. The detection of jaw fractures occurring in tooth extraction may be difficult. Moreover, treatment should be done immediately.
Comparison of laser and ozone treatments on oral mucositis in an experimental model

Oral mucositis (OM) induces severe pain and limits fundamental life behaviors such as eating, drinking, and talking for patients receiving chemotherapy or radiotherapy. In addition, through opportunistic microorganisms, OM frequently leads to systemic infection which then leads to prolonged hospitalization. Severe lesions often adversely affect curative effects in cancer cases. Therefore, the control of OM is important for oral health quality of life and prognosis. Low-level laser therapy (LLLT) and ozone may be useful to accelerate wound healing. In this study, 24 Sprague-Dawley rats were divided into three groups as control, ozone, and laser groups. All groups received 5-fluorouracil intraperitoneally and trauma to the mouth pouch with a needle. After the formation of OM in the mouth, the control group had no treatment; the ozone group was administered ozone, and the laser group, LLLT. Then, all groups were sacrificed and basic fibroblast growth factor (bFGF), transforming growth factor (TGF-beta), and platelet-derived growth factor (PDGF) were evaluated in all groups. LLLT was determined to be statistically significantly more effective than ozone on FGF and PDGF. However, in respect of TGF-beta, no statistically significant difference was observed between the groups. In conclusion, within the limitations of this study, LLLT is more effective than ozone. However, further studies on this subject are required.
Limitations of Panoramic Radiographs: Report of Two Cases

Panoramic radiographs are valuable and technically easy procedures in determining lesions and the other pathological conditions of the jaw. However, it should be recognized that there are obvious limitations in these films. These limitations include distortions, magnifications, and difficulties in identifying the relationship of the lesions with vital structures. This study presented two cases that indicated the limitations of panoramic radiographs. In the first case, a radiolucent lesion was detected on panoramic radiography. The borders of the lesion were associated with the mandibular canal and mental foremen. In the second case, two radiolucent areas were seen on panoramic radiography. They were determined to be in relation to the maxillary sinus and mental foramen. Following the screening panoramic examination, cone beam computed tomography (CBCT) was obtained in both of the cases. The CBCT views demonstrated no relationship between the lesions and the anatomical structures detected in the panoramic radiographs. In conclusion, using only panoramic radiographs is not enough for the detection of the anatomic relationships and borders of the lesions. We suggest that dentists need 3D images to provide the correct information for presurgical assessments.
Recurrent Cherubism in an Adult Patient

Cherubism is an uncommon, nonneoplastic, fibro-osseous disorder of the jaws in childhood and adolescence. It affects the jaw bones by deforming the cortical shell. Clinical features include progressive painless and mostly bilateral expansion of the mandible and/or maxilla. Because fibrous connective tissue replaces osseous tissue, radiographic features generally include expansile osteolytic lesions and a ground-glass appearance. Several treatment protocols for cherubism have been recommended in the literature; however, despite surgical curettage treatment, recurrences may occur.
