An appropriate material and technique can prevent this. This study aimed to evaluate the sealing ability of Mineral Trioxide Aggregate MTA Glass Ionomer Cement GIC and Biodentine as a furcation repair material with and without laser.Methods Ninety human extracted mandibular molars were decoronated 3 mm above and below the cementoenamel junction. After access opening sticky wax was placed over the canal orifices. A defect of 1 mm diameter was made the chamber and perforation were flushed with water and dried. Further the specimens were divided into six groups based on the furcation repair materials used n 15. Group 1 MTA with laser Group 2 MTA Group 3 GIC with laser Group 4 GIC Group 5 Biodentine with laser and Group 6 Biodentine. In groups 1 3 and 5 diode 810 laser irradiation was done for furcal defect before placing the materials. Specimens were subjected to 2 methylene blue for 48 hr washed sectioned mesiodistally and depth of dye penetration was examined under stereomicroscope. Statistical software SPSS version 22 was used for analysis. One way analysis of variance followed by Post hoc Tukey multiple comparison test was done p le0.05.Results Among the experimental materials less microleakage was observed with laser activation than without using laser. Biodentine with laser Group 5 showed less microleakage which was statistically significant compared to all the other groups except group 6 i.e Biodentine without laser.Conclusion Biodentine with laser activation was effective in furcation repair and in prevention of microleakage.nbsp","PeriodicalId":155332,"journal":{"name":"RGUHS Journal of Dental Sciences","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127637254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here 4 to 5mm thickness of composite resins can be placed andcured in asingle step so that time consuming layering technique can be eliminated. The purpose of this study was to investigate the flexural strength and depth of cure of two bulk fill composites and to compare it with a universal composite. Materials and method: Two bulk fill composites (Sonic fill and Filtekbulkfill) and one universal composite (Filtek Z350 XT) were used. Ten samples per group were made using rectangular split brass mold following ISO standard 4049 to measure the flexural strength. Each sample was then subjected to three point bend test using universal testing machine until failure occurred. For depth of cure measurements, ten samples per group were made using cylindrical brass mold and were subjected to acetone shake test for 30 sec. The dimensions of the samples were measured using Vernier callipers and compared. One-way analysis of variance followed by Tukey’s post-hoc test was used to determine the statistical differences among groups at significance of p<0.05. Results: Sonicfillgave highest flexural strength value and Filtek Z350 XT the least. There was no statistically significant difference between the flexural strength of Filtekbulkfill and Filtek Z350 XT. For depth of cure, Filtekbulkfill showed higher value than other tested groups. Conclusion: All the tested materials showed significantly higher flexural strength values than the minimum flexural strength (80MPa) that is required for use in stress bearing areas. Sonicfill composite produced highest value of flexural strength than other composites, which may bedue to its increased percentage of filler content. For depth of cure, both the tested bulkfill composites showed lesser value of depth of cure than that claimed by manufacturers .","PeriodicalId":155332,"journal":{"name":"RGUHS Journal of Dental Sciences","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124834209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Pre-treatment lateral cephalograms of twenty-five children (10 boys, 15 girls) were taken. The children selected for the study were in the age group of 5 – 13 years (mean age of 10 years) during the year 2008- 11. All the tracings were made on 75µm lacquered polyester acetate tracing papers using a 0.05” lead pencil. This study assessed the associations of upper lip strain and upper pharynx size with selected cephalometric measures. The data was analyzed using SPSS (Statistical Package for Social Science, Ver.10.0.5) package. Results: The increased upper lip strain was associated with a forwardly placed maxilla, increased mandibular plane angle and upper pharynx size was associated with decrease in mandibular size (mandibular corpus size), increase in gonial angle (Ar-Go-Gn), decrease in middle third of face (N- ANS) and increase in lower jaw anterior face height (ANS- Me). Also, the dental effect of increase in the degree of mandibular incisor proclination relative to mandibular plane was observed. Conclusion: With an increase in upper-lip strain and decreased upper pharynx size, forward maxillary placement, retrognathic mandible, downward and backward rotation of the mandible, decreased middle third of face, increase in lower anterior face height and increase in degree of mandibular incisor proclination relative to mandibular plane were observed. It was inferred from the present study that a decreased upper airway affects the craniofacial skeletal growth pattern in children.","PeriodicalId":155332,"journal":{"name":"RGUHS Journal of Dental Sciences","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132168023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
