Objective: To determine the distribution of oro-mucosal lesions in patients of Maharishi Markendeshwer College of Dental Sciences and Research, (MMCDSR), Mullana. Further to identify sex predilection and different sites which are more susceptible to different oro-mucosal lesions. Materials and methods: A hospital based retrospective study was carried out from 1st January 2007 till 31st December 2009 at (MMCDSR), Mullana. A total of 451 biopsy reports were studied. Distribution and prevalence of oro-mucosal lesions among the data were analyzed using SPSS software package version 13.

Treatment of cervicofacial actinomycosis: a report of 19 cases and review of literature
2013
Objectives: Actinomycosis is a chronic suppurative granulomatous infection caused by the Actinomyces genus. Orocervicofacial actinomycosis is the most common form of the disease, seen in up to 55% of cases. All forms of actinomycosis are treated with high doses of intravenous penicillin G over two to six weeks, followed by oral penicillin V. Large studies on cervicofacial actinomycosis are lacking. Therefore proper guidelines for treatment and treatment duration are difficult to establish. The aim of this study is to establish effective treatment and treatment duration for orocervicofacial actinomycosis. Study design: A Pubmed and Embase search was performed with the focus on treatment and …
Evaluation of endovenous sedation using BIS monitoring in dentistry. A systematic review
2018
Background The aim of the present review was evaluate the utility and validity of the Bispectral Index (BIS) in dental treatment carried out under endovenous sedation, and compare its efficacy with clinical sedation scales. Material and Methods Electronic and manual literature searches were conducted by two independent reviewers for articles published up to April 2017 in several databases, including Medline and Cochrane Library. Results Sixteen articles met the inclusion criteria. A correlation was identified between BIS and clinical sedation scales. A BIS range between 75 and 84 showed a high probability of corresponding to an Observer’s Assessment of Alertness and Sedation Scale (OAA/S) v…
Anti-inflammatory effects of zinc in PMA-treated human gingival fibroblast cells
2015
Objectives: Abnormal cellular immune response has been considered to be responsible for oral lesions in recurrent aphthous stomatitis. Zinc has been known to be an essential nutrient metal that is necessary for a broad range of biological activities including antioxidant, immune mediator, and anti-inflammatory drugs in oral mucosal disease. The objective of this study was to investigate the effects of zinc in a phorbol-12-myristate-13-acetate (PMA)-treated inflammatory model on human gingival fibroblast cells (hGFs). Study Design: Cells were pre-treated with zinc chloride, followed by PMA in hGFs. The effects were assessed on cell viability, cyclooxygenease-1,2(COX-1/2) protein expression, …
Tutorial in oral antithrombotic therapy: biology and dental implications.
2013
Objectives: Recent developments of new direct oral anticoagulants that target specific clotting factors necessitate understanding of coagulation biology. The objective of this tutorial is to offer dental professionals a review of coagulation mechanisms and the pharmacodynamics of the conventional and new oral anticoagulants. Also, we summarized the dental implications of the conventional and new anticoagulants. Method: We searched Medline using search terms “antithrombotic”, “antihemostasis” or “anticoagulation” and combined them with the search results of “dental”, “oral surgery” or “periodontal”. We restricted the results to “human” and “English”. Results: The early coagulation cascade, t…
Accidental displacement of a dental implant into the sublingual space: A Case report
2016
Dental implant surgery is continuously expanding. In fact, every day more and more surgeons are choosing dental implants for allowing great results in the field of oral rehabilitation. However, these procedures are not exempt from complications. This report presents the case of a 66 years old man underwent implant surgery by a specialized dentist. No problems were reported during implant placement. Despite this, three months later, it was displaced into the sublingual space at the time of uncovering. Against this backdrop, the patient was referred to an expert maxillofacial surgeon. Next day, the implant was removed using an intraoral approach to reach the sublingual space. According with o…

Logistic regression models to estimate odds ratios and 95% confidence intervals were used to investigate th…
The effect of radiotherapy on survival of dental implants in head and neck cancer patients
2016
Objectives: To explore the current literature of the survival of dental implants in irradiated head and neck cancer patients considering the role of implant location, bone augmentation, dose of radiation and timing of implant placement.

Studies on animal subjects and craniofacial implants were excluded. Results: 18 articles out of 27 were eligible for inclusion in this systematic review. 12 out of 18 studies reported favorable outcome of dental implants and radiotherapy with survival…
Pyogenic granuloma in relation to dental implants: Clinical and histopathological findings
2015
Background: The occurrence of pyogenic granuloma in association to dental implants is rare and only five cases have been reported in the literature. Material and Methods: Patients charts were analyzed to select patients who had been diagnosed for pyogenic granuloma and its association with dental implants had been evaluated.

The central odontogenic fibroma: How difficult can be making a preliminary diagnosis
2016
Central odontogenic fibroma (COF) is a rare benign odontogenic tumor derived from the dental ectomesenchymal tissues. A 16-year-old Caucasian female patient was referred by her dentist for a radiolucent asymptomatic area associated with the crown of the impacted lower right third molar. A preliminary diagnosis of a follicular cyst was supposed. The lesion was surgically removed under general anesthesia together with the impacted tooth. The microscopic diagnosis of the excised tissue revealed an odontogenic fibroma. No clinical or radiographic signs of recurrence were found five years after surgical excision. Despite the various differential diagnoses of homogeneous unilocular and well delim…
