Imaging Characteristic of 11 Lesions of Odontogenic Keratocyst in the Indian Subpopulation: A Cone-Beam Computed Tomography Experience.

BACKGROUND: The clinical feature and radiographic appearance of orthokeratinized odontogenic keratocyst (OKC) are not characteristic, which may lead to the misdiagnosis. The radiographic appearance of OKC may range from a small unilocular radiolucency to a large multilocular radiolucency, resembling other odontogenic cysts and tumors. AIM: The aim was to illustrate the characteristic feature of OKC presented on the digital panoramic radiograph and cone-beam computed tomography (CBCT), which may provide great value for the differential diagnosis and the treatment planning and also to compare the various radiographic features of OKC in CBCT and digital panoramic radiograph. MATERIALS AND METHODS: Digital panoramic and CBCT records of seven cases, with 11 lesions of OKC were analyzed retrospectively from the patients' database from our institute (2014 to 2016), which was histopathologically diagnosed as OKC. RESULTS: The mean age of the patients was 24.1 years, and the female-to-male ratio was 3: 4. Six of 11 lesions were localized within the mandible, and five lesions were in the maxilla. CONCLUSION: The presurgical assessment with radiological information is extremely important for treatment planning, and CBCT provides us with an accurate and faster three-dimensional representation of a lesion at a lower dose and cost, but the role of panoramic radiograph cannot be refuted.

Arteriovenous malformation of the parotid gland: Diagnostic perspective- A case report.

Arteriovenous malformation (AVM) of the parotid gland is an extremely rare condition with very few cases reported in the literature. Majority of the swellings in the parotid region are usually due to sialadenitis, tumour etc., therefore making the initial diagnosis of vascular malformation may be difficult if there is no evident Turkey-wattle sign. Here, we present a case of AVM of parotid gland with its clinical features, radiographic features and its management. The lesion, being a high flow one, was managed with sclerosing agents to regress its size.

Photobiomodulation in oral medicine: a review.

Photobiomodulation (PBM) or low-level laser therapy (LLLT) in dentistry is an evolving science, with an increasing number of controlled clinical studies exploring its potential as a treatment modality. The present study provides an outline of the biologic mechanism of PBM and summarizes the findings of clinical studies of PBM for specific applications in oral medicine. Controversies and drawbacks associated with PBM, which require further research, are also identified. Current literature reports the potential of PBM in various applications in oral medicine. Furthermore, well-documented research confirms its efficacy in certain conditions, such as oral mucositis, recurrent herpes simplex infection, and burning mouth syndrome. The absence of any reported adverse effects is an advantage over conventional therapeutic modalities. While PBM has proved to be effective for some specific applications, it is not a panacea. The paucity in standardized studies, coupled with ambiguity over the laser parameters, has limited its credibility as a therapeutic modality.

Role of oral fluids in DNA investigations.

The assay of oral fluid (OF), a biofluid historically well-studied biochemically and physiologically, is a growing area of research with implications for basic and clinical purposes. In the last decade, it has gained considerable attention and lately, the use of OF has provided a substantial addition as an investigative tool in forensic and/or legal procedures. This article is an appraisal of various applications of OF sourced DNA in the field of forensic analysis. We have discussed the significance of different collection methods and their variations along with the application of specific analytical methods based on the condition of the sample. It is likely that the germaneness of OF assays will continue to expand thus providing a new instrument for investigation in criminal/legal proceedings.

Gorlin-goltz syndrome.

The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome-NBCCS) is a rare autosomal dominant syndrome caused due to mutations in the PTCH (patched) gene found on chromosome arm 9q. The syndrome, characterized by increased predisposition to develop basal cell carcinoma and associated multiorgan anomalies, has a high level of penetrance and variable expressiveness. GGS is a multidisciplinary problem, early diagnosis of which allows introduction of secondary prophylaxis and following an appropriate treatment to delay the progress of the syndrome. The following report emphasizes the need for awareness of the diagnostic criteria of this syndrome in cases with no typical skin lesions.
