Sublingual epidermoid cyst: a case report

Of all the epidermoid cysts encountered throughout the body, only 7% occurs in the head and neck area, with the oral cavity accounting for only 1.6%. Intraorally this benign slow growing and painless entity is usually located in the submandibular, sublingual and submental region. They can cause symptoms of dysphagia and dyspnoea and have a malignant transformation potential. Surgical excision is the treatment of choice. Described here is a case of gigantic sublingual epidermoid cyst

Grade V cherubism: A rare and aggressive entity

Cherubism is a non-neoplastic, rare, hereditary childhood disease of bone characterized by bilateral enlargement of the jaws caused by bone degradation and replacement by fibrous tissue. The affected child is reminiscent of the cherub portrayed in Renaissance art. We report the clinicopathological and radiographic features of cherubism and review of literature

A comparative evaluation of film and digital panoramic radiographs in the assessment of position and morphology of impacted mandibular third molars

Background and Objective: Digital photo stimulable phosphor (PSP)-based radiography has many known theoretical advantages over conventional film radiography but its diagnostic efficacy has to be assessed clinically. This study compared the efficiency of conventional film-based panoramic radiographs with that of digital PSP-based panoramic radiographs in the assessment of position and morphology of impacted mandibular third molars. Materials and Methods: We selected a total of 80 impacted mandibular third molars that fulfilled the inclusion and exclusion criteria of this study. Both conventional film-based panoramic radiographs and digital PSP-based panoramic radiographs were taken of all the study samples and the teeth were later surgically removed. Conventional film-based and digital PSP-based panoramic radiographs were compared for their relative efficiencies in the assessment of impaction status, position of tooth, number of roots, root morphology, and proximity to mandibular canal of impacted mandibular third molars. An oral surgeon graded these same factors during/after surgical exploration and this assessment was considered the gold standard. The data obtained were statistically analyzed using descriptive statistics, chi-square test, and McNemar′s test. Results: There was no statistically significant difference between conventional film-based radiographic assessment and digital PSP-based panoramic radiographic assessment of impaction status, position of tooth, number of roots, and proximity to mandibular canal of impacted mandibular third molars (P>0.05). However, there was significant difference between the two methods with regard to assessment of root morphology of impacted mandibular third molars (P=0.00). Interpretation and Conclusion : Conventional film-based panoramic radiographs and digital PSP-based panoramic radiographs were comparable in their accuracy in the preoperative study of impacted mandibular third molar with regard to impaction status, tooth position, number of roots, and proximity to the mandibular canal. Digital PSP-based panoramic radiographs were more accurate than conventional film-based panoramic radiographs in the assessment of root morphology of impacted mandibular third molars. Hence, we conclude that digital PSP-based panoramic radiographs can be used as an effective alternative to conventional film-based panoramic radiographs for assessment of position and morphology of impacted mandibular third molars

Central schwannoma of mandible

Intraoral schwannomas are uncommon and intraosseous ones are even rarer. The intrabony lesions account for less than 1% of the central neoplasms.According to the literature, there have been reports of 44 cases of intrabony neurilemmomas that occurred in either of the jaws. In theis case report. we report a case of central schwannoma of the mandible in a 23-year-old female, who presented with a swelling involving the right body of the mandible. Radiographs revealed a well defined, unilocular radiolucency with bicortical expansion. Histopathology and immunohistochemistry confirmed the diagnosis of schwannoma arising from right inferior alveolar nerve. The lesion was treated by segmental resection and reconstructed with autogenous iliac bone graft

Osteochondroma of the condyle

Osteochondroma, also known as osteocartilaginous exostosis, is a benign cartilage capped outgrowth attached to the underlying skeleton by a short stalk. Osteochondroma is frequently seen in the axial skeleton but rarely occurs in the craniofacial skeleton. We report a case of osteochondroma arising from the right mandibular condyle
