Periodontics is a clinical science which deals with diseases of periodontium and periodontal tissues are the supporting apparatus of the tooth which has many hidden genetic components that could be useful in the field of Forensic science. Though Periodontium has rich source of evidence as that of tooth but it is usually unfocused. Utilizing periodontal evidences and records Periodontist could serve in featuring the ante mortem and post mortem changes in gingival tissues. It is essential to bring the important hidden aspect of tooth supporting apparatus in the field of Forensic deontology to light that could aid during various crucial periods. This article highlights the importance of periodontal tissues in various aspects of forensic research and justifies the role of periodontist in forensic odontology.

Malignancies are preceded by potentially malignant disorders. Leukoplakia is one of the precursors of oral squamous cell carcinoma. Leukoplakia is one of the types of potentially malignanat disorder that have potential to convert into carcinoma frequently. Leukoplakia poses a major diagnostic and therapeutic challenge. We present a case of leukoplakia in left side of buccal mucosa which is converted into carcinoma in situ along with review in light of current information from the literature. We also attempt to present the clinical relevance, and the therapeutic modalities available for the management of the disease.

Localized gingival growths are one of the most frequently encountered lesions in the oral cavity and Peripheral ossifying fibroma (POF) is one of them. This case report discribes the growth that occurred in the maxillary anterior region with displacement of anterior teeth along with its satisfactory management and literature review. Peripheral ossifying fibroma represents a reactive benign lesion of connective tissue and is not the soft tissue counterpart of ossifying fibroma. Peripheral ossifying fibroma in the age of 21 years, and in male patient arising in the maxillary anterior region, is an occasional entity. Careful clinical examination and histopathology findings should be correlated to conclude the final diagnosis.

Conclusion: Maximum tear strength is indicated by the samples manipulated with the water having minimum dissolved salts i.e. distilled water.

Introduction: : Dental ceramics are widely regarded as one of the best restorative materials for the oral cavity. Ceramics are naturally chemically inert and nontoxic in nature. This study was done to evaluate the surface roughness of dental porcelain when subjected to different surface treatments i.e, glazed, reglazed and chair side polishing using porcelain adjustment kit followed by diamond polishing paste.

Materials and method: Total of50 samples of dental porcelain were fabricated using custom made metal mould with dimensions of 10mm thickness and 2mm width. Samples were randomly divided into five groups of 10 sampels each. Samples were then subjected to surface treatments viz glazed (Group I, control), abraded and reglazed (Group II), abraded and polished with porcelain adjustment kit (shofu) (Group III), abraded and polished with diamond polishing paste (Group IV), abraded and polished with combination of porcelain adjustment kit followed by diamond polishing paste (Group V).

Result: Minimum surface roughness was observed in Group II-Reglazed (0.459).

Conclusion: Ceramic restorations adjustment in dental clinics, when diamond polishing paste was used after porcelain adjustment kit, it may provide finish equal to glazed and reglazed surface

Erythema multiforme (EM) is an acute, self-healing inflammatory mucocutaneous disorder which presents with diverse spectrum of cutaneous lesions, hence termed "multiforme". Oral lesions are quite characteristic and manifest as rapidly rupturing vesicles & bullae forming ill-defined erosions and hemorrhagic encrusted lip lesions. Wide variety of triggering factors for EM have been documented in the literature, but history of prior herpes simplex virus (HS) infection is most widely accepted. EM has been chiefly divided into two main forms- EM minor and EM major. Steven Johnson syndrome & Toxic epidermal necrolysis (Lyell's disease) are now considered as distinct clinical entities. EM has a self-limiting course and the lesions usually resolve within few weeks. This paper aims to present a recent update on Erythema Multiforme taking into account its etiopathogenesis, clinical and oral features, diagnostic aids and treatment protocols.
