Abstract: Solitary well differentiated papillary mesothelioma is an unusual variant of epithelial mesothelioma. Most of them exhibit either benign or indolent behavior. Making the differential diagnosis between this rare tumor and serous papillary carcinoma can be problematic. We report here a case of a 24 year-old unmarried female with a well differentiated papillary mesothelioma of peritoneal origin.

Abstract: Statement of problem: Flexural strength is important in determining the strength of interim restorations and it is especially important in long span and long term interim restorations. Studies comparing the flexural strength of provisional restorative materials are limited and inconclusive. Aim: To compare the flexural strength of provisional restorative material fabricated using light polymerized composite resin, Urethane dimethacrylate (UDMA) and auto polymerized resin, Poly Methyl Methacrylate (PMMA)

Keywords – Flexural strength, Provisional restoration, Polymethyl methaacrylate (PMMA), Urethane dimethacrylate (UDMA).

Abstract: Bronchial artery embolization (BAE) is a well-established minimally invasive procedure in the management of moderate to massive and recurrent hemoptysis. The bronchial circulation aneurysms and dilatations are commonly responsible for the hemoptysis and have an easy approach through the descending aorta via the femoral or subclavian route by angiography. There are very few common complications associated with the procedure are recurrence of hemoptysis, chest pain, cough, dysphagia .Paraplegia secondary to embolization of the anterior spinal artery is a very rare but serious complication. Proper identification of the culprit bronchial vessel and pre-embolization study of its anastomosis are useful measures to minimize the chances of this dreaded complication.

Abstract: Background: Orthodontic diagnosis and treatment planning requires the patient's history, extra and intra oral examination, analysis of diagnostic records comprising of orthodontic photographs, radiographs and study casts. Tooth-size is the sum of the mesio distal widths of the maxillary and mandibular teeth. For ideal occlusion, teeth in both arches should be proportional in size. Tooth size analysis was presented by Bolton in 1958. The ratio for anterior segment was derived to be 77.2±0.22% and 91.3±0.26% for the whole arch. Material And Methods: Cross sectional data was gathered from the study casts of patients undergoing orthodontic treatment. 115 out of 160 study casts were filtered based upon the inclusion and exclusion criteria. ANB angle and Witt's appraisal were traced on corresponding lateral cephalograms. The mesio distal widths of all maxillary and mandibular teeth from right first molar to left first molar were calibrated with the use of a manual caliper. The readings were then used to compute the anterior and total Bolton ratios. Results: Significantly higher mean anterior tooth ratios were found for Class II (p<0.01) patients. All other ratios were within close range of Bolton's norms. Conclusions: Skeletal Class II patients showed a tendency towards higher mesiodistal widths of teeth in the mandibular anterior region.
