This book was released on 2012 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since their introduction in 1970, glass ionomer cements have been used in a wide variety of clinical situations in dentistry. The main advantages of glass ionomer cements are chemical bonding, fluoride release and uptake, excellent seal against microleakage, and biocompatibility. The main objective of this study was to compare the microleakage of two new paste-paste glass ionomer systems to their traditional RMGIC counterparts when conditioning the dentin with newly developed no-rinse conditioners or polyacrylic acid. Materials and methods: Standardized cavity preparations were made, centered on the cementoenamel junction of the buccal surface, on 96 extracted human molars divided in 8 groups (n = 12). G1 Ketac Nano with Ketac Nano Primer, G2 Ketac Nano with Ketac Conditioner, G3 Photac Fil with Ketac Nano Primer, G4 Photac Fil with Ketac Cavity Conditioner, G5 Fuji Filling LC with GC Self Conditioner, G6 Fuji Filling LC with GC Cavity Conditioner, G7 Fuji II LC with GC Self Conditioner, G8 Fuji II LC with GC Cavity Conditioner. The cavities were treated with either a no-rinse or polyacrylic acid conditioner and restored with a paste-paste RMGIC or traditional RMGIC from the same manufacturer (n =12). The teeth were then sealed to within 2 mm of the restoration margins and thermocycled. The teeth were immersed in 2.0-percent methylene blue and stored at room temperature for 24 hours. Then, the teeth were be embedded in resin and sectioned longitudinally in a buccolingual direction making 1 section (1 mm thick) per tooth. The occlusal and gingival restoration margins of each specimen were examined with a stereomicroscope at X10 magnification to determine the degree of microleakage. Results: Mixed-model ANOVA was used to test the fixed effect of the eight groups and cervical vs. occlusal location within each tooth sample on microleakage, with sample as the random effect. Both main effects and the interaction are significant, p

Download or read book An in Vitro Comparison of Microleakage with E Faecalis in Teeth with Root end Fillings of Proroot MTS and Brassler s EndoSequence Root Repair Putty written by Beau John Brasseale and published by . This book was released on 2011 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brasseler USA (Savannah, GA) developed and introduced a bioceramic putty called EndoSequence Root Repair Material (ERRM) that can be used as a retrofilling material for surgical endodontics. The material is said to have many of the same chemical, physical, and biological properties as mineral trioxide aggregate (MTA), but with superior handling characteristics. The material is composed of calcium silicates, monobasic calcium phosphate, zirconium oxide, tantalum oxide, proprietary fillers, and thickening agents. ERRM is said by the manufacturer to bond to adjacent dentin, have no shrinkage, be highly biocompatible, hydrophilic, radiopaque, and antibacterial due to a high pH during setting. Investigations on the sealing properties of this material have not yet been conducted. The purpose of this study was to compare the microbial leakage of Enterococcus faecalis in teeth with root-end fillings using ProRoot MTA and Brasseler's ERRM in a dual-chamber bacterial leakage model as described by Torabinejad and colleagues. The aim of this investigation was to compare the bacterial microleakage of these two root-end filling materials exists. Sixty-two human, single-rooted, mandibular premolars in which extraction was indicated were accessed and instrumented in an orthograde fashion with hand and rotary files. Root resection of the apical 3 mm was then completed and root-end retropreparations were created for placement of root-end filling material. Twenty-seven of these premolars had root-end fillings using ProRoot MTA and 27 had root-end fillings using ERRM. Two teeth were used as a positive control group with no root-end filling, and two other teeth were used as a negative control group and were sealed and coated with dentin bonding agent. The teeth were then evaluated for microleakage using a dual-chamber bacterial microleakage model for 40 days as described by Torabinejad and colleagues. Microleakage was determined by the presence of turbidity in the lower chamber of the apparatus and was assessed each day. Fresh samples of E. faecalis were used every three days to inoculate the apparatus and serve as a bacterial challenge for the materials. Results were recorded every day for 30 days. The outcome of interest (bacterial turbidity) and time-to-leakage (in days) were determined for each of the samples. Survival analysis was used to compare the two groups with a Kaplan-Meier plot to visualize the results and a nonparametric log-rank test for the group comparison. The microleakage of ERRM was not statistically different (p> 0.05) than leakage of ProRoot MTA when subjected to E. faecalis over the 40 day observation period. Both groups had a small number of early failures (within 4 days) and no leakage was observed for the remaining 40 days of the study. Therefore, the null hypothesis was rejected. The results of this research support the use of either of these two materials when compared with the controls. The microleakage of Brasseler's EndoSequence Root Repair Material was at least as good as ProRoot Mineral Trioxide Aggregate when tested with E. faecalis.

This book was released on 1990 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most common in vitro method for determining microleakage involves sectioning and scoring restorations in dye-treated extracted teeth. Investigators differ on the number of sectioned surfaces per restoration to measure to assign a score that is most descriptive of the degree of microleakage. The purpose of this study was to measure and compare the microleakage of class V box and V-shaped preparations restored with composite using a two surface and a multiple surface scoring mthodology. Twenty molar teeth each received ane box and one V-shaped preparation on the mesial or distal surface. Occlusal margins were in enamel and gingival margins were in cementum-dentin. Teeth were randomly restored with one of the two composites to comprise four treatment groups with 10 restorations in each group. Two groups received box shaped preparations and were restored with either Dual Cure Scotchbond, P-30 or Scotchbond 2, P-50. Two groups received V-shaped preparations and were restored with either Dual Cure Scotchbond, P-30 or Scotchbond 2, P-50. Teeth were stored for 7 days in normal saline or and thymol, thermocycled, and subjected to silver nitrate staining. Each restoration was then cut into four sections with 8 surfaces. All surfaces were randomly scored by two calibrated examiners. Spearman Rank Correlation determined intra-rater reliability for scoring box and V-shaped preparations to be ≥ 0.74 and ≥ 0.85 respectively. Inter-rater reliability for scoring box and V-shaped preparations was ≥ 0.79 and ≥ 0.84 respectively. Median microleakage scores were determined for central, lateral and end locations for each group, as well as for combined surface locations. A Wilcoxon Matched-Pairs Signed-Rank Test found a statistically significant difference between an end two surface location and a multiple surface scoring methodology for V-shaped preparations restored with Scotchbond 2, P-50 (p ≤ 0.05). No other statistically significant comparisons were detected. A Friedman Two-way Analysis of Variance by Ranks Test found no statistically significant difference in median microleakage scores between central, lateral and end surface locations for each group (p ≤ 0.05) Representative samples and microkeakage patterns were photographed at x30 magnification.
