Materials and Methods: A total of 120 glass ring molds (8.5 mm in inner diameter and 2 mm in height) were prepared after which the internal surface of the molds were etched with hydrofluoric acid for 5 min. The test materials (n = 20/group) were placed into the molds and thereafter sandwiched between two glass slides. All groups were polymerized for 20 s using a high-intensity quartz tungsten halogen (HQTH) light unit (Optilux 501). The volumetric polymerization shrinkage for each pits and fissure sealant was measured using the specific density method modified by Puckett and Smith. All data were analyzed statistically using one-way analysis of variance and Tukey honest significant difference (HSD) test at P < 0.05. Results: A ranking for the shrinkage values were obtained as follows: Teethmate F-1 (7.40 ± 1.17%) > Clinpro TM Sealant (6.60 ± 1.54%) > Dyract Seal (5.38 ± 1.30%) > Smartseal & loc F (5.06 ± 1.22%) > Fissurit FX (4.30 ± 1.15%) > Helioseal F (3.30 ± 0.69%). Clinpro TM Sealant and Teethmate F-1 displayed the highest shrinkage values (P < 0.05). The lowest shrinkage values were obtained with Helioseal F (3.30 ± 0.69%) and Fissurit FX (4.30 ± 1.15%) (P < 0.05).

The public concern about appearance has been partly responsible for increased awareness in esthetic dentistry and consequently bleaching techniques. Bleaching solutions have been reported to cause alterations and loss of mineral content in surface enamel after bleaching. These irregularities in enamel surface could result in more susceptibility to re-pigmentation, thereby adversely affecting the whitening treatment. Aim: To evaluate the susceptibility of teeth to re-pigmentation using two different bleaching materials, i.e. 35% hydrogen peroxide (H 2 O 2 ) and 16% carbamide peroxide. Subjects and Methods : In this study, 30 extracted teeth were divided in three groups. Group I was bleached with 35% H 2 O 2 , Group II with 16% carbamide peroxide, and Group III was used as control. They were then stained with silver nitrate stain to evaluate their susceptibility to pigmentation after bleaching. The shade of each tooth was recorded before bleaching, after bleaching, and after pigmentation using a Vita shade guide. Results: Results showed that after staining with silver nitrate, the teeth in all groups became darker but the amount of change in the shade value of the samples was different for the two groups. The change of shade was greater for Group I as compared to Group II after pigmentation. This change in shade between Groups I and II was found to be statistically significant using one-way ANNOVA test (P < 0.05). Conclusions : Thus, we concluded that susceptibility to pigmentation increases after bleaching. Furthermore, pigmentation is greater when H 2 O 2 is used for bleaching.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"2 1","pages":"78 - 82"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74976199","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: A total of 60 specimens were obtained from 60 extracted sound human maxillary central teeth. The specimens were randomly divided into three groups (n = 20). Group A was the control group (no bleaching). In Group B, the specimens were bleached with Opalescence Xtra Boost (Ultradent), and in Group C, they were bleached with Smartbleach (High Tech Laser). These groups were then divided into two subgroups (n = 10 in each) according to the colorant solution used: tea and cola. Each bleaching agent was applied to the specimens according to the manufacturer′s recommendations. After bleaching, the first color of the specimens was determined with a spectrophotometer according to the CIELAB color system (∆E). Following immersion in the staining solutions, the color was determined after 15 min, 6 h (second day), and 36 h (sixth day), and the color change values were calculated. The results were analyzed statistically by two-way analysis of variance (ANOVA) and Tukey′s honest significant difference (HSD) test (P < 0.05). Results: The bleached specimens showed more staining than the unbleached specimens (control group). In all the groups, the staining was more severe in the cola solutions than in the tea solutions. There were no statistically differences in staining of the teeth in the control group (P > 0.05). In the specimens bleached with Smartbleach, staining in cola solution was greater than tea solution and this difference was statistically significant (P < 0.05). Conclusions: The staining of the bleached specimens was similar in the tea and cola solutions. The bleached specimens showed more staining than the unbleached specimens.

Materials and Methods: The 60 recently extracted sound human molar teeth were sectioned at the level of the highest pulp horn to obtain dentin discs of 0.5 ± 0.2 mm. The dentin discs were numbered and permeability measurements were done before and after the operation for the same sample. For simulating direct pulp capping, dentin discs were perforated with a standard diamond bur and restorated with four different capping materials: Dycal, Calcimol light-curing (LC), ProRoot MTA and DiaRoot BioAggregate. Fluid movement measurements were tested with a CFF method and a mean value was calculated for each specimen. Results: Calcimol LC and Dycal showed significantly higher fluid conductance values compared to other pulp capping materials (P < 0.05). There were no significant differences between ProRoot MTA and DiaRoot BioAggregate (P > 0.05).

Materials and Methods: Polyether and polyvinyl siloxane impressions of an International Organization for Standardization-specified test-block were photographed at two temperatures and 3 time intervals. This resulted in 12 groups (n = 10). Images were digitally calibrated and measured. Mean percentage dimensional change (%DC) was analyzed using the Variance Estimation and Precision module of Statistica 10 (Statsoft®, Southern Africa) (95% confidence), with Fisher least significant difference correction for multiple pairwise comparisons. Results: For silicone, dimensional accuracy was highest when stored at 21°C for 14 days (%DC = 0.006). This was significantly better than all other silicone groups (P < 0.05). Dimensional accuracy was worst when stored at 21°C for 8 h (%DC = 0.237) and after cooling-off from 66°C (%DC = 0.300), with no difference between latter groups (P = 0.187). For polyether, dimensional accuracy was highest when stored at 21°C for 14 days (%DC = −0.272). This was significantly better than all other polyether groups (P < 0.05). Dimensional accuracy was worst when stored at 21°C for 8 h (%DC = 0.364) and after cooling-off from 66°C (%DC = 0.306), with no difference between latter groups (P = 0.199). Comparing polyether with silicone, %DC did not differ between the two materials when kept at 21°C for 14 days and when cooled-off after heat exposure for 8 h. At all other instances, the %DC between the two materials differed, with silicone always closest to zero %DC. Conclusions: Exposing silicone and polyether to high temperature doesn′t lead to higher dimensional inaccuracy on the short-term compared to keeping them at 21°C. However, heat has an effect on shelf-life (14 days) of impressions, decreasing accuracy. This effect is worse for polyether.","PeriodicalId":17076,"journal":{"name":"Journal of Restorative Dentistry","volume":"1 1","pages":"6 - 12"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76964106","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}
