Introduction: It has been postulated that crown angulation and inclination has potential space implication within the arch. With the insight of space implication of the axial relations of teeth, cases of genuine tooth size discrepancies can be dealt with improved stability. Aim: This in vitro study was designed to investigate and quantify the influence of angulation and inclination of maxillary incisors on the effective arch perimeter. Materials and Methods: Acrylic teeth were arranged over typhodont frame with spaced maxillary anterior segment. Known value of tip and torque in increments were incorporated to maxillary incisors through bracket positioning and corresponding consumption of the interdental spaces were measured using coordinate measuring machine. Results: Study revealed that increase in maxillary incisor crown angulation by 1o results in consumption of approximately 0.012 mm of arch perimeter. Similarly, there is a consumption of 0.021 mm of arch perimeter with each degree increase in labial crown inclination. Conclusion: The knowledge of the space implication can be included in the space analysis during the orthodontic treatment planning. Depending upon the amount of space discrepancy, an accurate degree of required alteration in the axial relation of one or more teeth can be planned. © 2017, Journal of Clinical and Diagnostic Research.

Osteoma is a benign osteogenic lesion which is composed of well differentiated mature compact and/or cancellous bone that proliferates continuously. Its prevalence is 4%. Its pathogenesis is still controversial. Solitary peripheral osteoma of craniofacial region is a rare finding. We report a case of 30-year-old female having solitary peripheral osteoma present on the lingual cortex of the left posterior mandible which was initially asymptomatic but now is causing discomfort while chewing and not associated with Gardners syndrome. We also laid emphasis on its clinical, differential diagnosis, radiological, surgical, and histopathological features. The aim of this paper is to present an uncommon case of solitary peripheral osteoma in the mandible along with analysis of literature for peripheral osteomas of jaws and to contribute to the knowledge concerning the pathogenesis, differential diagnosis, and management of these lesions.

Engineering has not only developed in the field of medicine but has also become quite established in the field of dentistry, especially Orthodontics. Finite element analysis (FEA) is a computational procedure to calculate the stress in an element, which performs a model solution. This structural analysis allows the determination of stress resulting from external force, pressure, thermal change, and other factors. This method is extremely useful for indicating mechanical aspects of biomaterials and human tissues that can hardly be measured in vivo. The results obtained can then be studied using visualization software within the finite element method (FEM) to view a variety of parameters, and to fully identify implications of the analysis. This is a review to show the applications of FEM in Orthodontics. It is extremely important to verify what the purpose of the study is in order to correctly apply FEM.

Background: In oral carcinoma much effort has been made to predict the prognosis of patients but a sound understanding of underlying cell biology is likely to need progress. Recently, attention has been directed towards tumour associated tissue eosinophils and mast cells and their role in the biologic behavior of tumours. Aim: The retrospective study was used to evaluate the influence of tumour associated tissue eosinophils and mast cells on prognosis of oral squamous cell carcinoma (OSCC). Material and methods: The follow-up, of histopathologically diagnosed thirty cases of OSCC, was carried out for minimum period of 3 years. Special stains are wonderful they allow us to see which we can not see clear with routine H&E stain.Tissue sections were stained with special stains, Carbol Chromotrope for tissue eosinophil and Toluidine blue for tissue mast cell staining. Result: The results of the present study shows that increase infiltration of tissue eosinophils and mast cells in OSCC, associated with favourable prognosis. Conclusion: We concludes that infiltration of tissue eosinophils and mast cells are indicators of favourable prognosis in OSCC. Thus quantitative assessment of eosinophils and mast cells are the most important aspects of the microscopic evaluation of OSCC. © 2011 Debta P, et al.

Aim: The aim of this study was to compare effect of different metal coping designs on fracture resistance of porcelain in metal ceramic restorationsMaterials and Methods: Fracture resistance of porcelain was assessed in porcelain fused to metal crowns with three different coping designs i.e. metal coping extension on labial surface upto gingivoaxial line angle, metal coping extension 1mm short of the gingivoaxial line angle and metal coping with 0.4mm wide labial metal collar. For crowns without labial metal collar margin; shoulder porcelain was used to build the labial cervical margin of the crowns.Results: Results were assessed with statistical analysis using the student unpaired‘t’ test. Visual examination of the fractured specimens of group A, B and C showed remarkably similar failure modes with nearly all specimens failing through a shear fracture of porcelain from load point to facial margin of the crown.Conclusion: Within the scope of this study, it was observed that the mean facture strength of the samples with shoulder porcelain labial margins having metal coping design extending uptogingivoaxial line angle of the finish line was highest as compared to samples with shoulder porcelain labial margins having metal coping design 1mm short of gingivoaxial line angle & samples having porcelain fused to metal coping design with 0.4mm wide metal collar. © 2014, Journal of Clinical and Diagnostic Research.

Loss of the continuity of the mandible destroys the balance and the symmetry of mandibular function, leading to altered mandibular movements and deviation of the residual fragment towards the surgical side. This clinical report gives a brief review of resection guidance prosthesis and describes the fabrication of an acrylic guidance flange prosthesis. Successful intercuspal position was accomplished through the use of the guidance appliance, combined with physiotherapy in a patient who underwent a hemisection of the mandible, subsequent to treatment for an ameloblastoma.

The trial compared wound healing clinically, histologically and morphometrically after the use of fibrin sealant and sutures for periodontal flap closure. Ten patients were selected for this split-mouth randomized controlled clinical trial. On the test site fibrin sealant (F) was applied for flap closure after periodontal flap surgery (n = 10) and on the control site sutures (S) were used (n = 10). Clinically wound healing was observed at 7, 14 and 21 days and biopsy was taken on the 8th day. At seventh day better healing was observed in fibrin sealant site. Histologically mature epithelium and connective tissue formation was seen in fibrin sealant site with increased density of fibroblasts (F = 70.45 ± 7.22; S = 42.95 ± 4.34, p < 0.001) and mature collagen fibers. The suture site had more number of inflammatory cells (S = 32.58 ± 4.29; F = 20.91 ± 4.46, p < 0.001) and more number of blood vessels (S = 11.89 ± 3.64; F = 5.74 ± 2.41, p = 0.005). Fibrin sealant can form a better alternative to sutures for periodontal flap surgery.

Chronic Lymphocytic Leukaemia (CLL) is a monoclonal lymphoid malignancy characterized by progressive accumulation of small, mature but functionally incompetent neoplastic lymphocytes in the peripheral blood, bone marrow and lymphoid organs. Patients present a variable course and may not require early intervention unlike other malignancies. Patients with rapidly deteriorating blood counts, and organomegaly need treatment. Alkylating agent live Bendamustine combined with Rituximab, anti-CD 20 monoclonal antibody have shown promising results in such patients. Anaemia, neutropenia and thrombocytopenia have been reported as treatment emergent events with this combination therapy. Neutrophils are the major innate defense and their depletion can result in a wide range of opportunistic infections. This case report discusess the oral and dermal lesions which emerged with the Rituximab and Bendamustine combination therapy in a patient with CLL and their management.

To compare the canal transportation, centering ability, and remaining dentin thickness of WaveOne and ProTaper systems using cone beam computed tomography.Forty extracted human single-rooted premolars were used in the present study. Preinstrumentation scanning of all teeth was taken; canal curvatures were calculated, and the samples were randomly divided into two groups, with twenty samples in each group; one group was instrumented with WaveOne system and the other group with ProTaper rotary system. Postinstrumentation scans were performed, and the two scans were compared to determine canal transportation, centering ability, and remaining dentin thickness at 3 mm, 6 mm, and 9 mm from the root apex.Students unpaired t-test.Using Students unpaired t-test, results were as follows: for canal transportation, Group 1 showed significant difference at 3 mm and 6 mm and insignificant difference at 9 mm while Group 2 showed insignificant difference in all the three regions. For centering ability and remaining dentin thickness, Group 1 showed insignificant difference at 3 mm and 9 mm while significant difference at 6 mm was obtained. When comparison of remaining dentin thickness was done at three levels using two groups WaveOne and ProTaper, there was no significant difference between two groups.(1) WaveOne single reciprocation file system respected better canal anatomy better than ProTaper. (2) Individually, centering ability of WaveOne was better at 3 mm, 6 mm, and 9 mm levels. (3) However, ProTaper individually was better centered at 3 mm (apical third) and 9 mm (coronal 3(rd)) levels than 6 mm level (middle third).
