The mouth is a mirror of health or disease, a sentinel or early warning system. The oral cavity might well be thought as a window to the body because oral manifestations accompany many systemic diseases. In many instances, oral involvement precedes the appearance of other symptoms or lesions at other locations. Oral lichen planus (OLP) is a chronic mucocutaneous disorder of stratified squamous epithelium of uncertain etiology that affects oral and genital mucous membranes, skin, nails, and scalp. LP is estimated to affect 0.5% to 2.0% of the general population. This disease has most often been reported in middle-aged patients with 30-60 years of age and is more common in females than in males. The disease seems to be mediated by an antigen-specific mechanism, activating cytotoxic T cells, and non-specific mechanisms like mast cell degranulation and matrix metalloproteinase activation. A proper understanding of the pathogenesis, clinical presentation, diagnosis of the disease becomes important for providing the right treatment. This article discusses the prevalence, etiology, clinical features, oral manifestations, diagnosis, complications and treatment of oral LP.

Background: Plagiarism is stealing of some others work or idea without proper citation. It is one of the biggest challenges faced by the scholarly world and by far a grim form of delinquency in academics. Aim: The study was designed to explore the knowledge and attitudes of dental professionals toward plagiarism. Materials and Methods: A questionnaire having 14 questions was sent either via e-mails or by sending printed copies to 5000 dental professionals, while maintaining anonymity of all the participants. Result: Most of the dental professionals know about plagiarism, and they believe that plagiarism cannot be avoided successfully. Pressure to publish was a major reason along with several others, which accounts for more and more indulgence in plagiarism. At the same time lack of facilities in private institutions and lack of funding for research work were the major factors as well, which hinder in creating research environment and hence promotes plagiarism and false studies to publish it. Conclusion: Plagiarism is present in dental professionals and that significant reduction can only be brought by awareness, objective check methods and stringent punishment. Plagiarism and other forms of academic misconduct must be recognized and must not be tolerated.

Background: Reconstruction of cranial defects due to trauma or other causes has been carried out since ages with a wide variety of materials. The aim of reconstruction was mainly to restore cosmesis and protect the brain from further injury. However, recent studies have shown that cranioplasty not only improves the cerebral blood flow but also leads to improvement of cognitive functions. The materials used include autologous bone, allogeneic bone, xenografts, and alloplasts. The search for an ideal material continues. The authors present their experience with cranioplasty using prefabricated porous polyethylene implants. Materials and Methods: Patients requiring cranioplasty for reconstruction of large sized (more than 15 cm in any 1 dimension) cranial defects were selected. Three patients were men and 2 were women. The age group of the patient ranged from 18 to 58 years. Preformed Biopore Hemisphere was used in every patient for cranial reconstruction. Results: No complications were seen in our patients. One patient who had undergone titanium cranioplasty previously showed remarkable improvement in cognitive functions. Conclusion: Porous polyethylene prefabricated implants are a good restorative material for reconstruction of large cranial defects. Copyright © 2016 Mutaz B. Habal, MD.

Aim: To measure the amount of fluoride released and re released after recharging from various restorative materials: Conventional Glass Ionomer Cement (Fuji II), Light Cure Resin Modified GIC (Fuji II LC), Giomer (Beautifil II), Compomer (Dyract). Materials and Methods: Fifteen cylindrical specimens were prepared from each material. The specimens were immersed in 20 ml of deionized water. The amount of released fluoride was measured during the 1st day, 7th day and on the day15 by using specific fluoride electrode and an ion-analyser. After 15 days each material was divided into three Sub Groups of five samples each. Sub Group A served as control, Sub Group B was exposed to 2% NaF solution, Sub Group C to 1000ppm F toothpaste. The amount of fluoride re-released was measured during the 1st day, 7th day and on the day15 by using specific fluoride electrode and an ion-analyser. The results were statistically analysed using analysis of variance (one-way ANOVA) and Tukey Kramer multiple comparison tests (p≤0.05). Results: Independent of the observation time period of the study the Conventional GIC released the highest amount of fluoride followed by RMGIC, Giomer and Compomer. The initial burst effect was seen with GIC'S but not with Giomer and Compomer. After topical fluoride application fluoride re release was highest in Sub Group B and GIC had a greater recharging ability followed by RMGIC, Giomer and Compomer. The fluoride re release was greatest on 1st day followed by rapid return to near exposure levels. Conclusion: From the study it was concluded that, the initial Fluoride release was highest from Conventional GIC followed by Resin Modified GIC, Giomer and Compomer. The Fluoride re release was high when recharging with professional regime (2% NaF) as compared to home regime (Toothpaste). Conventional GIC had a greater recharging ability followed by Resin Modified GIC, Giomer and Compomer. © Journal of Clinical and Diagnostic Research. All rights Reserved.

Background: Many studies have reported an association between periodontitis and adverse pregnancy outcomes, but there has been little research on the knowledge of obstetricians regarding oral care. The aim of the study was to assess the knowledge and attitudes of practicing obstetricians in India about the relationship between oral health and pregnancy outcomes, as well as their practice behaviors regarding oral healthcare in pregnant women in Indian settings. Methods: A structured online questionnaire was sent to 130 obstetricians in the city of Chandigarh and adjoining areas of the union territory. The questionnaire was prepared by dentists and obstetricians and was validated in a prior pilot study. Obstetricians' knowledge of the effects of pregnancy on oral health, and vice versa, were correlated with their experience and practices. Results: A total of 79.2% responded to the questionnaire. More than 70% of respondent obstetricians correctly knew of the effects of periodontitis on preterm birth and low birth weight babies. Only 40% recommended dental examination during pregnancy and 47% advised patients about oral care during pregnancy. There were significant correlations between knowledge of dental health effects on pregnancy and referrals of patients to dentists. Conclusions: This study found that although obstetricians generally were knowledgeable about appropriate dental care practices during pregnancy as well as the relationship between oral health and pregnancy outcomes, this knowledge often did not translate into appropriate practice behavior.

The knowledge and the understanding of the role of growth factors, their mechanisms of action, and molecular signaling pathways, which have been reviewed in this article, suggest the potential for many novel therapeutic targets, not only for applying growth factors but also for the potential use of growth factor inhibitors or agents that target specific parts of the intracellular signaling pathways in controlling oral pathologies. There remains an enormous challenge to convert some of the knowledge from basic studies of bone cell physiology and inflammatory cells to therapeutically useful techniques for the future.

Public concerns about incinerator emissions, as well as the creation of federal regulations for medical waste incinerators, are causing many health care facilities to rethink their choices in medical waste treatment. As stated by Health Care Without Harm, non-incineration treatment technologies are a growing and developing field. Most medical waste is incinerated, a practice that is short-lived because of environmental considerations. The burning of solid and regulated medical waste generated by health care creates many problems. Medical waste incinerators emit toxic air pollutants and toxic ash residues that are the major source of dioxins in the environment. International Agency for Research on Cancer, an arm of WHO, acknowledged dioxins cancer causing potential and classified it as human carcinogen. Development of waste management policies, careful waste segregation and training programs, as well as attention to materials purchased, are essential in minimizing the environmental and health impacts of any technology.

The world of fashion is ever changing and this dynamics applies to dentistry. As dentistry and dental treatments have become necessary facet of a healthy life and therefore down the line fashion prospect of tooth jewellery are also getting fused into it.To assess the knowledge and practice of tooth jewellery among practicing dentists of Tricity, India.A descriptive, cross-sectional study was conducted among 310 dental practitioners in Tricity (Chandigarh, Mohali and Panchkula), India. A self-administered, close-ended questionnaire was distributed among all the dental practitioners in order to assess their knowledge and practice regarding tooth jewellery. Responses of the questionnaire was obtained on the dichotomous scale with Yes and No. Right answers were given a score of 2 whereas the wrong answers were given as score of 1. The data was analyzed using unpaired students t-test, one way ANOVA (analysis of variance) and multivariate logistic regression.A significant difference was observed among the genders with males being three times more knowledgeable (OR=3.5, 95%CI: 0.8-2.8). It has been found that knowledge and practice scores of dental practitioners who spend more than 10 hours per day have two times more knowledge (OR= 2.3, 95%CI:0.08-1.1) than others. The dentists holding the masters degree were having three times more knowledge than the graduates ones (OR= 2.3, 95%C.I:0.1-1.9).The present study concluded that dental practitioners had sufficient knowledge about tooth jewellery. Practice of tooth jewellery in the dental clinics was found to be adequate but it was also associated with some complications. To overcome this, it is advised that professional and government bodies should create strategies for enhancing and improving peoples knowledge as well as make them aware of the pros and cons while using tooth jewellery which shall further enhance their smile.

Oral squamous cell carcinoma (OSCC) ranks as one of the most common types of cancer and oral potentially malignant lesions (OPMLs) provides with an overall increased risk for development of carcinoma. As podoplanin expression is attracting interest as a marker for cancer diagnosis and prognosis, this study assesses the role of podoplanin expression in such lesions.Podoplanin expression and lymphatic vessel density (LVD) was determined using D2-40, a marker for podoplanin, in 70 diagnosed cases of potentially malignant lesions and OSCC.Normal epithelium showed negligible podoplanin expression, whereas the expression extended predominantly at the basal layer and the suprabasal layer or above at one or multiple areas in potentially malignant lesions. Podoplanin expression in OSCC showed two different patterns-diffuse and focal. A statistically significant increase in mean LVD was seen from normal epithelium to potentially malignant lesions (P < 0.001) and to OSCC (P < 0.022) while a non-significant increase was seen (P < 0.594) between OPMLs and OSCC. Overall no significant correlation was found between D2-40 epithelial positivity and LVD (P = 0.122).This study suggests the utility of podoplanin as a biomarker for cancer risk assessment as it detects the early changes and thus provides an additional value beyond current clinical and histopathological evaluations. Hence, podoplanin is suggested to be a marker of tumor initiation and to a lesser extent of tumor progression.
