Self-injurious behavior is a deliberate alteration or damage without suicidal intent. Herein, we report a patient who had caused intentionally self-trauma to his left lower permanent canine and placed a long metallic foreign body into the root canal. History revealed a habit of placing metallic objects in the form of stapler pins into the mouth, but closer examination revealed the habit to be more as a method of self-injurious behavior. Following an episode of severe pain, the tooth was endodontically treated after removal of the foreign body that was corroding. Clinical significance of the case report is that the patient may just be put off as having a habit of inserting foreign objects into the mouth, but the behavior was more self-injurious in nature.

Introduction: Oral Submucous Fibrosis (OSMF) is an oral potentially malignant condition caused predominantly by areca nut chewing. Early recognition with accurate staging of the disease and appropriate treatment planning is of utmost importance to prevent the malignant transformation and to improve the quality of life of the patient. Picrosirius red stain is specific for collagen and enhances its birefringence under polarising light producing different colours in different stages of the disease. Aim: To compare the clinical and functional staging with histopathologic staging methods used to assess the severity of OSMF and to perform a qualitative analysis of the collagen fibres in various histopathologic stages of OSMF using picrosirius red stain and polarising microscope. Materials and Methods: It is a retrospective study done on archival samples. The study sample included a total of 30 cases which was divided into two groups. Group I comprised of 20 OSMF samples and Group II comprised of 10 normal tissue samples. Clinical, functional and histopathological staging was performed for all OSMF samples. Comparative analysis between clinical and functional stages with the histopathological staging was done using chi square test. Picrosirius red-stained sections of OSMF were analysed using polarising microscopy to evaluate the qualitative changes in the collagen fibers. Statistical Analysis Used: Descriptive data which includes frequency and percentages were calculated for each group. Categorical data were analysed by chi-square test. A p-value of 0.05 or less was considered statistically significant. Results: Comparative analysis between clinical and functional stages with the histopathological staging revealed a significant correlation (p < 0.05) between the functional and histopathological stage. Enhanced birefringence of the collagen fibers due to picrosirius red stain yielded characteristic prominent polarising colours in different stages of OSMF. Conclusion: Comparison of functional staging with histopathologic grading is more reliable in determining the severity of the disease than the clinical staging. Production of characteristic polarising colours by various stages of picrosirius red stained sections of OSMF substantiates the use of picrosirius red stain and polarising microscope as a tool in assessing the severity of this condition thereby aiding in better treatment planning. © 2016, Journal of Clinical and Diagnostic Research.

Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign, highly vascular, and locally aggressive tumor that predominantly occurs in adolescent males. Usually, the presenting symptom is a painless nasal obstruction or epistaxis; however, other symptoms may develop depending on the size and extent of the tumor mass. Owing to the vascularity of the tumor, incisional biopsy is not attempted. The diagnosis is dependent on multiplanar imaging modalities like Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Angiography. These imaging modalities help in assessing the tumor mass, pre-operative embolization of the feeder vessel, and treatment planning. Usually, patients with JNA are diagnosed by otorhinolaryngologists, but here, we present a rare case of JNA reporting to the dental hospital due to a tender palatal swelling. © 2013 Mishra S.

Background: This paper highlights the unusual and rare presentation of a cementoblastoma in the maxilla. It also discusses a review on this odontogenic pathology. Case report: We present a cementoblastoma appearing in an atypical site in a young girl. The presenting clinical features with radiologic features are reviewed. Also discussed is an approach to radiological interpretation. To the best of our knowledge, this is only the seventeenth case to be reported in literature. Discussion: Cementoblastoma is a benign true neoplasm which forms a mass of cementum or cementum-like tissue on the root surface of the tooth. As a maxillofacial practitioner, it is essential to consider cementoblastoma as one of the differential diagnosis, although rare, while considering maxillary swellings. The treatment remains fairly conservative, with an excellent prognosis. © 2011 Springer-Verlag.

Antioxidants are substances that when present at very low concentration inhibits the oxidation of a molecule. It has the capacity to nullify the ill effects of oxidation caused by free radicals in the living organisms. The unpaired electrons of these free radicals are highly reactive and neutralize the harmful reactions of human metabolism. Protection of the body against free radicals is provided by some enzymes which come under a distinctive group, concerned solely with the detoxification of these radicals. Superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase are the key enzymatic antioxidants of this defense system by which the free radicals that are produced during metabolic reactions are removed. This review highlights the mechanism of action of enzymatic antioxidants SOD, GPX and catalase and its role in oral disease. © 2015 Journal of Pharmacy And Bioallied Sciences | Published by Wolters Kluwer - Medknow.
