Aims: To compare the sealing ability and antimicrobial activity of three temporary sealing materials: Caviton, MD Temp and IRM Materials and Methods: In the present in vitro study, sealing ability (dye penetration method using 2% methylene blue) was measured with class I cavities on human premolars restored using test materials. The antimicrobial activity (agar diffusion test) of the materials was evaluated against Streptococcus mutans (MTCC 497 and clinical isolate) and Candida albicans (ATCC 60193 and clinical isolate). Statistical Analysis Used: For sealing ability, data was statistically analyzed using Chi-square test at a significance level of 5% using Statistical Package for Social Sciences (SPSS) 15.0. Antimicrobial activity was evaluated by comparing the mean diameter of the inhibition zones formed around the respective wells. Results: IRM produced best marginal sealing (Fisher′s exact test = 38.361 and P < 0.001) and was also associated with higher antimicrobial activity in comparison to Caviton and MD Temp. The inferior properties of MD temp can be attributed to thermal instability demonstrated by MD Temp leading to an inadequate seal, and also failed to produce a zone of inhibition. IRM proved effective and superior to Caviton and MD Temp in both these aspects. Conclusions: The success of an endodontic treatment depends on the effective seal achieved following debridement. This study stresses the need for an adequate marginal seal along with satisfactory antibacterial potential for a temporary sealing material.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"9 1","pages":"13 - 19"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86621317","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}

However, detector dyes are not specific to bacteria and can discolor surrounding healthy tissues as dentino-enamel junction or the circumpulpal dentine. Possible discoloring effect of CD dye over restorative materials have not been evaluated until date. The aim of this study was to investigate the staining effects of four commercial CD dyes Caries Detector (CAD), Caries Marker (CAM),SEEK (SEE), Sable Seek (SES) on a variety of tooth colored restorative materials; Filtek Valux Plus (VLX), Filtek Z250 (Z25), Filtek Silorane (SIL) Fuji IX (FUJ). Materials and Methods: A total of 40 disc-shaped specimens were prepared from each restorative material. After 24 h distilled water storage, baseline color was measured according to the Commission International de l′Eclairage LFNx01 aFNx01 bFNx01 system by using a reflection spectrophotometer. Each CD dye was applied to 10 samples of each composite group for 10 s and applications were repeated for 2 times. Before the final color measurements, all samples was rinsed and dried. Color differences (ΔE) were measured and analyzed the data with two-way analysis of variance and Tukey honest significant difference post-hoc tests. Results: Independent of dyes, perceptible color changes were observed in glass ionomer restorative material (FUJ) (ΔE ab FNx01 > 3.3). CAD, CAM and SES caused staining on highly triethylene glycol dimethacrylate monomer containing composite resin (VLX). Silorane based restorative material (SIL) and micro hybrid resin composite (Z25) were more resistant to discoloration then VLX and FUJ (P < 0.05). Conclusion: CD dyes may cause discolorations in some restorative materials and should be used with maximum care.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"56 1","pages":"20 - 26"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90311860","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}

Lack of this may lead to microleakage. The aim of this study was to observe the characteristic features of the composite resin-tooth interface under transmitted light microscope using acetate paper peel technique and to determine its feasibility in microleakage evaluation. Materials and Methods: Standardized class I cavity was prepared and restored with Filtek Z350 XT composite resin on three extracted human maxillary premolars. The occlusal surface of one of the restored premolars was made flat and the other two premolars were sectioned buccolingually and a flat surface was obtained. All the three samples were embedded in epoxy resin, polished, etched with 37% phosphoric acid, washed with distilled water and then dried. Acetone was flooded onto the prepared surface and a pre-cut acetate film was placed onto it. As the acetone evaporated, the film gets settled down to take the shape of micro relief produced by etching. The film was left over to dry for 15-20 min. The film was gently peeled off and mounted on a glass slide with a cover slip and observed under transmitted light microscope at different magnifications. Results: At lower magnification (×4), the intricate details of the composite resin-tooth interface could be observed, but the formation of resin tags and a thick dark band of hybrid layer was clearly visible only at higher magnification (×40). Furthermore, the interfacial gap between the restoration-tooth interfaces could be measured at ×40 magnification. Conclusions: This technique is an efficient way to study the interfacial space between the restoration and the tooth but by measuring the interfacial gap at a particular point it would be difficult to comment on the microleakage aspect.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"91 1","pages":"37 - 40"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86810819","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}

Materials and Methods: The roots of 90 maxillary incisors were prepared with ProTaper rotary files until reaching to size F4. The roots were divided into four experimental ( n = 20 each) and two control groups ( n = 5 each). The experimental groups were filled as follows: Group 1, Cold lateral condensation using gutta-percha/AH Plus Jet; Group 2, Single-cone ProTaper gutta-percha/Guttaflow2; Group 3, Single-cone Propoint PT/Smartpaste; and Group 4, Single-cone Propoint PT/Smartpastebio. The sealing ability of root canal fillings was tested at different time intervals using the glucose leakage model. Glucose leakage values were measured (mg/dL) by a spectrophotometer and statistically analyzed. Results: All experimental groups presented significantly different glucose leakage at all experimental periods ( P < 0.05). There was a progressive increase in the glucose leakage during the experimental periods in all groups. During experimental periods, Groups 4 showed the lowest significant cumulative glucose leakage values ( P < 0.05). Conclusion: Single-cone obturation technique using Propoint PT and Smartpastebio sealer provided the superior sealing ability and may be considered an alternative to the lateral condensation technique.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"15 1","pages":"1 - 5"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74080107","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}

Materials and Methods: One-hundred and eleven extracted human canines were cleaned and prepared using a rotary nickel titanium files with crown-down technique. All the teeth were filled with gutta-percha and then the apical third of each root was resected perpendicularly to the long axis direction. After, root-end cavity was prepared using a round bur. The specimens were randomly divided into 7 groups of 15 samples, filled with one of the test materials (Ionofil, Ketac Molar Quick Aplicap, Argion Molar AC, Photac Fil Quick Aplicap, Fuji II LC Capsule, Dyract Extra, Glasiosite Caps) and were stored at 37°C and 100% humidity for 7 days. 1-week later, apical parts of roots of 10 ± 0.05 mm were attached to the computerized fluid filtration device. The data obtained were analyzed using an ANOVA and post hoc Tukey′s tests (P ≤ 0.05). Results: Statistical analysis indicated that RF with Argion molar AC (reinforced GIC) had the least micro-leakage of all and whereas Ketac Molar Quick Aplicap (conventional GIC) showed highest apical leakage than the other groups. Conclusion: This present study has shown that none of GICs, which used as a RF material unable to prevent apical leakage exactly and Argion Molar AC is used as a RF material among current GICs better than others.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"43 1","pages":"27 - 31"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81297403","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}
