Pycnodysostosis is a rare craniofacial syndrome characterized by dwarfism, cranial anomalies, diffuse osteosclerosis where multiple fracture of long bones and osteomyelitis of jaw are frequent complications. This clinical entity was first described in 1962 by Maroteaux and Lamy. This article presents two clinical cases of pycnodysostosis with their clinical and radiological characteristics. © 2015, Journal of Clinical and Diagnostic Research. All right reserved. Source

Introduction: Surgical extraction of mandibular third molar is the most frequently performed procedure in oral surgery. This procedure is associated with significant postoperative sequelae such as trismus, swelling, pain and infection. The need of antibiotic therapy during the removal of mandibular third molar has been a contentious issue. Method: This study investigated a regimen by using amoxycillin and metronidazole in one group and without using antibiotics in the other. Both the groups were assessed postoperatively on the 1st, 2nd, 5th, 7th and 10th days by the same observer for post operative mouth opening (interincisal distance), presence of a purulent discharge at the site of surgery, pain and swelling. Result: Overall, no statistically significant difference was seen between both the treatment groups when interincisal distance, pain, swelling and purulent discharge were considered. Conclusion: The results of this study failed to show any advantage which was associated with the routine postoperative use of antibiotics in asymptomatic third molar surgeries. Source

Presently, bone replacement grafts are one of the modalities of therapy for which there is histologic evidence of regeneration coronal to the base of the previous osseous defect. Bioactive glasses are used extensively in medicine and dentistry. This study evaluated the additional efficacy of a bioactive alloplast, PerioGlas, in comparison with open flap debridement only. 8 systemically healthy volunteers were chosen, each having 2 collateral sites with ≥6 mm clinical probing depth and radiographic evidence of an intrabony defect. Randomly, one defect was treated with open flap debridement plus bioactive glass (test) and the other with open flap debridement alone (control). At baseline, 3, 6, 9 months measurements were recorded which included plaque index, gingival index, pocket probing depth, clinical attachment level, and increase in gingival recession. Standardized radiographs were used to measure defect fill and alveolar crest resorption. The data were subjected to statistical analysis. Both treatments showed no significant differences between the two groups at any point of time. However, radiographically, bioactive glass group showed significant improvement in bone fill over the sites treated with open flap debridement alone. The alloplastic bone graft material, PerioGlas, demonstrated clinical advantages beyond that achieved by debridement alone. © Medicina Oral S. L. Source

Objectives : To evaluate and compare the efficiency, marginal leakage and shear bond strength of Carisolv and Papacarie in primary molars. Method: Freshly extracted 60 human carious primary molars were randomly divided into two experimental groups - Group I [ caries removal by Carisolv ] and Group II [ caries removal by Papacarie ]. The amount of time taken for complete caries removal was recorded using a stopwatch. After bonded restorations, both the experimental groups were further randomly subdivided into four experimental groups and subjected to marginal leakage and shear bond strength evaluation. Results : Papacarie [ 337.67 ± 18.13 ] was clinically more efficient than Carisolv [461.33 ± 27.76 ] in removing caries with respect to time in seconds. 66.7% of teeth treated with Carisolv did not show any marginal leakage as compared to 20% with Papacarie. The mean [ ± SD ] shear bond strength of Carisolv [ 9.67 ± 3.80 ] treated teeth was slightly more when compared to Papacarie [ 8.36 ± 4.51]. Conclusion :Papacarie was clinically more efficient in caries removal but showed significantly more marginal leakage than Carisolv. Source

Background: Central and Peripheral giant cell granulomas of jaws are uncommon, benign, reactive disorders that are characterized by the presence of numerous multinucleated giant cells and mononuclear cells within a stroma. The origin of the multinucleated giant cells is controversial; probably originating from fusion of histiocytes, endothelial cells and fibroblasts. Objective: To assess the expression of CD34 and CD68 in central and peripheral giant cell granulomas to understand the origin of these multinucleated giant cells. Materials and Methods: Twenty cases of Central and Peripheral giant cell granulomas were evaluated immunohistochemically for CD34 and CD68 proteins expression. Results: Immunopositivity for CD34 was seen only in cytoplasm of endothelial cells of blood vessels; whereas, consistent cytoplasmic immunopositivity for CD68 was seen in few stromal cells. Statistical significance was seen in mean number of multinucleated giant cells, mean number of nuclei in multinucleated giant cells, CD68 expression and ratio of macrophages to multinucleated giant cells among two lesions. Conclusion: Although the central giant cell granulomas share some clinical and histopathological similarities with peripheral giant cell granulomas, differences in mean number of nuclei in multinucleated giant cells and CD68 immunoreactivity may underlie the distinct clinical behavior. © 2014, Medknow.
