A smile expresses a feeling of joy and success and also reveals self-confidence and kindness in an individual. A holistic smile is dictated not only by the shape, position and color of the teeth but also by the health of the gingival tissues. Gingival appearance is an important component of an attractive smile. Melonin, carotene and hemoglobin are the most common natural pigments contributing to the normal color of gingiva. Although physiologic and ethnic melanin pigmentation is not a medical problem, complaints about "black gums" are common. For de-pigmentation of gingiva, different treatment modalities have been reported such as bur abrasion, scraping with scalpel, partial thickness flap, gingivectomy, cryotherapy, electrosurgery, lasers, free gingival autografting, sub-epithelial connective tissue graft and combination techniques. In the present case reports, scalpel surgery and electrosurgery were performed for gingival de-pigmentation, which are simple and effective. The esthetic results were pleasing and healing was uneventful. Patients were satisfied with the outcome at three month follow-up as evidenced from their feedback.

The increase in white blood cell count (WBC) and platelet count due to systemic inflammation and infection is considered a risk factor for cardiovascular diseases. These parameters increase in periodontal disease. A decrease in WBC and platelet counts by periodontal therapy may decrease the risk for cardiovascular disease. The present study is a treatment intervention model to investigate the effect of non-surgical periodontal therapy on total leucocyte count (TLC), differential leucocyte count (DLC) and platelet count in patients with chronic periodontitis. Thirty systemically healthy patients were included in the study. Probing pocket depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), TLC, DLC, platelet count, bleeding time (BT) and clotting time (CT) were evaluated at baseline and at two weeks after phase I therapy. A statistically highly significant decrease in the percentage of sites exhibiting BOP was observed, i.e., from 78.1% at baseline to 18.1% two weeks postoperatively (p = 0.000). There was also a statistically significant decrease in TLC from 7595/mm3 at baseline to 6690/mm3 two weeks following phase I therapy (p = 0.02). There was also a statistically highly significant decrease in platelet count from 2.1 lac/mm3 preoperatively to 1.9 lac/mm3 at two weeks postoperatively (p = 0.003). The present study depicts the importance of periodontal therapy to reduce the TLC and platelet count, thereby possibly decreasing the risk for the development of cardiovascular disease by lowering the established risk factors for periodontal atherosclerosis.

Development of cancer in humans is a multistep process. Complex series of cellular and molecular changes participating in cancer development are mediated by a diversity of endogenous and exogenous stimuli and important amongst this is generation of reactive oxygen species (ROS). Reactive radicals and non-radicals are collectively known as ROS. These can produce oxidative damage to the tissues and hence are known as oxidants in biological system. Many researchers have documented the role of ROS in both initiation and promotion of multistep carcinogenesis. To mitigate the harmful effects of free radicals, all aerobic cells are endowed with extensive antioxidant defence mechanisms. Lowered antioxidant capacity or the oxidant-antioxidant imbalance can lead to oxidative damage to cellular macromolecules leading to cancer. Oral cavity cancer is an important cancer globally and tobacco is the primary etiological factor in its development. Tobacco consumption exposes the oral epithelium to toxic oxygen and nitrogen free radicals that can affect host antioxidant defence mechanisms. Elevated levels of ROS and Reactive Nitrogen Species (RNS) and lowered antioxidants are found in oral precancer and cancer. Protection can be provided by various antioxidants against deleterious action of these free radicals. Treatment with antioxidants has the potential to prevent, inhibit and reverse the multiple steps involved in oral carcinogenesis. This review is an attempt to understand the interesting correlation between ROS and RNS mediated cell damage and enzymatic and non-enzymatic defence mechanisms involved in oral cancer development and its progression and the use of antioxidants in oral cancer prevention and treatment. © 2013 Elsevier Ltd.

Mucoepidermoid carcinoma (MEC) is a malignant glandular epithelial neoplasm having an unpredictable behavior and a tendency to recur. Numerous parameters have been assessed to predict the outcome of this lesion, but have been deemed inadequate, with the exception of tumor stage and grade. In the present study, we attempted to correlate the proliferative activity of MEC with its histopathological grade, using argyrophillic nuclear organizer region (AgNOR) count. Thirty cases of MEC were included in the study. All the slides were stained using hematoxylin and eosin and silver nitrate techniques. Counting was performed at a magnification of x1,000 with an oil-immersion lens. Positive correlations were seen between AgNOR count and MEC grade (P < 0.05), with AgNOR count increasing in proportion with tumor grade. The AgNOR count in various grades of MEC indicates a relative progression in the proliferative activity of this tumor. This index is positively correlated with tumor grade, although there are some exceptions. The utility of AgNOR count in predicting the prognosis of MEC can be considered of importance; however, further assessment, such as survival studies, is necessary.

Aim: The aim of the present study was to clinically and radiographically evaluate Mineral Trioxide Aggre-gate (MTA) as an agent for pulpotomy in primary teeth and to compare it with that of Formocresol (FC) pulpotomy. Method: Seventy first and second primary mandibular molars of children were chosen on patients who required minimum two pulpotomies in either arch or same arch. After the standardized technique of Pulpotomy with MTA and Formocresol, all molars were treated with a thick mix of Zinc oxide Eugenol cement into the coronal pulp chamber followed by preformed stainless steel crown. The children were followed up for clinical and radio graphical examination after 6,12 and 24 month for Pain, Swelling, Sinus/fistula, Periapical changes, Furcation radiolucency and internal resorption. Results: MTA represents 97% clinical success rate in comparison to Formocresol with 85% success. Radiographically also MTA showed more promising results with 88.6% success in comparison to Formocresol with 54.3%. Conclusions: Thus, MTA pulpotomy has emerged as an easier line of treatment to save the premature loss of primary teeth due to caries or trauma.
