Materials and Methods: Class I cavities of width 2 × 3 mm were prepared on 120 permanent noncarious teeth. All samples were adjusted to maintain 2 mm dentin thickness within the pulp chamber and the cavity base. Venus Bulk Fill, Tetric Evo Ceram Bulk Fill, Filtek Bulk Fill, and Filtek Z250 were used as restorative materials. Materials were polymerized with Valo Light Emitting Diode (LED), Elipar S10, and Elipar Deepcure-S devices. A j-type thermocouple with microcirculation assemblies was used for measuring the temperature increments inside the pulp chamber during the polymerization of bulk-fill composite resins. The obtained data were recorded. Results: Statistically significant difference was found between the light sources and the temperature changes occurring during the polymerization (P <.05). The difference in temperature increases was found to be significant (P <.05) between restorative materials. The highest temperature rise values were obtained from Venus Bulk Fill. Conclusion: All light devices used in the study caused an increase in temperature in the pulp chamber in all groups. For all resin materials used, it was observed that the temperature values arising during the polymerization via used light sources did not exceed 5.5°C, which is the critical value for pulp.","PeriodicalId":43017,"journal":{"name":"Journal of Advanced Oral Research","volume":"35 1","pages":"207 - 215"},"PeriodicalIF":0.7,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83811933","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: In the study, samples were prepared using nanoceramic (Ceram.x one) and nanohybrid (GrandioSO) resin composites. Two different finishing and polishing systems were used in the polishing of resin composites. Resin composite surfaces were finished and polished under wet and dry conditions. The initial surface roughness values (Ra) of the samples were measured using a profilometer, whereas the color changes were measured using a spectrophotometer. Then, the colors of the samples kept in coffee were measured on the 7th and 30th days. Surface roughness and color change values (ΔE00) were measured and statistically analyzed using the one-way analysis of variance (ANOVA) test (P < .05). Results: Wet or dry use of polishing systems did not show a statistically significant difference between the surface roughness values of the resin composite (P < .05). Wet and dry use of polishing systems showed similar color changes on the composite resins (P < .05). Diamond-containing spirals on composite resins showed statistically less color change than aluminum-oxide-containing discs (P < .05). Wet or dry use of polishing systems did not reduce the color change of the composite resins below the acceptability threshold (AT). Conclusion: Wet or dry use of polishing systems on composite resins did not affect surface roughness and color change. The use of diamond-containing polishing spirals that cause less color change can increase clinical success.","PeriodicalId":43017,"journal":{"name":"Journal of Advanced Oral Research","volume":"49 1","pages":"127 - 134"},"PeriodicalIF":0.7,"publicationDate":"2022-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75878706","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}

The objective of the present in vitro study was to evaluate the effect of different fiber post-application techniques on the fracture resistance of premolars with flared root canals and no ferrule. Materials and Methods: Sixty freshly extracted, single-rooted mandibular premolars with no ferrule were endodontically treated by an experienced endodontist, and their root canals were experimentally flared. The specimens with flared root canals were divided into five groups according to fiber post-application techniques (n = 12): a prefabricated fiber post (G1), G1 + two auxiliary posts (G2), i-TFC post system (G3), G1 + quartz splint (G4), and Ribbond (G5). The data were analyzed with analysis of variance and Tukey tests. Results: The findings were revealed that no significant difference was found among four groups, except G5 (P > .05), which demonstrated the lowest fracture resistance (P < .05). G2, G3, G4, and G5 exhibited dominantly restorable fracture pattern, whereas G1 exhibited nonrestorable fracture pattern.

Results: As a result of our study, it was concluded that the CPB Primer was the agent with the highest antibacterial activity, including the control group. One of the remarkable findings in our study was that CPB Primer showed the most significant effect against Streptococcus mutans among microorganisms. Although not statistically significant, the antibacterial effect of adhesive agents at the end of the 48th h was found to be higher than at the end of the 24th h (P > .05).

The aim of the study is to examine the existing evidence base surrounding the oral health impacts of APECED and consider the wider clinical significance of the condition relevant to the provision of pediatric dental care. Materials and Methods: The evidence surrounding APECED and the oral health impacts obtained from a review of multiple databases was qualitatively summarized in the form of a literature review. A case study was used to illustrate the relevance of literature in caring patients with APECED. Results: The literature describes a broad range of impacts from APECED, although it is characterized by chronic candidal infection, autoimmune hypoparathyroidism, and Addison’s disease. Oral manifestations of APECED appear frequently and can present early. Developmental defects of the teeth affect a large proportion of patients with APECED and together with candidiasis, characterize the key oral manifestations of the disease. An enhanced preventive and minimally invasive approach to oral health care is recommended for these patients in light of the complexities of their medical condition.

Materials and Methods: Eighty dentin specimens were prepared from freshly extracted human third molar teeth and were classified, randomly (n = 20). Half of groups were treated with calcium phosphate based Teethmate Desensitizer and then Panavia V5, RelyX Ultimate (containing self-etch primer), Panavia SA, and RelyX U200 self-adhesive resin cements were luted to all dentin surfaces. All specimens were stored in an incubator at 37°C for 24 h. Shear bond strength was tested by a universal test machine at a 0.5 mm/min crosshead speed. The data were analyzed with a statistical program. Two-way ANOVA was used for statistical differences (P <.05). Dentin surfaces were examined with scanning electron microscopy (SEM) at x5000 and x10000 magnifications. Results: The higher shear bond values were observed in the groups with Teethmate Desensitizer applied and cemented with self-etch (16.05 ± 6.24 and 14.73 ± 4.75), whereas the lowest bonding values were observed in the groups with self-adhesive resin cement without Teethmate Desensitizer (3.73 ± 0.77 and 5.85 ± 4.19; P <.001). As the main effect of the treatment, the bond strength was 9.39 ± 6.04 in the control group, whereas it was 13.49 ± 5.44 in the Teethmate applied groups (P <.05) Conclusions: Calcium phosphate desensitizer did not adversely effected shear bond strength of self-etch/adhesive resin cements to dentin. It even significantly increased the shear bond strength of self-adhesive resin cements.","PeriodicalId":43017,"journal":{"name":"Journal of Advanced Oral Research","volume":"419 1","pages":"85 - 90"},"PeriodicalIF":0.7,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79567317","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}
