Six groups of 15 specimens were allocated as follows: ultrasonic + ProRoot MTA, ultrasonic + Biodentine, ultrasonic + TotalFill, laser + ProRoot MTA, laser + Biodentine, and laser + TotalFill. Roots were sectioned longitudinally to expose the filling material. Apical and coronal micrographs were taken, and the greatest distance between dentin and filling material was measured. The total gap area was also calculated using further micrographs.Results: Cavities prepared with the ultrasonic tips and filled with Biodentine showed significantly greater gap dimensions compared with TotalFill (p < 0.001) and ProRoot MTA (p = 0.007) in the apical region. The ultrasonic group showed significantly higher void values compared to the laser group for ProRoot MTA (p = 0.026), when comparing the total values of void. The Biodentine group was significantly higher than the TotalFill group in root-end cavities prepared with ultrasonic tips (p < 0.001). The Biodentine group was significantly higher than the ProRoot MTA group in root-end cavities prepared with the laser tip (p = 0.002).Conclusions: Under the conditions of this study, it was determined that the root-end cavity preparation technique had an effect on the amount of gaps formed between the dentin and the three filling materials.","PeriodicalId":21102,"journal":{"name":"Restorative Dentistry & Endodontics","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145024131","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}

Temperature on the external surface of each tooth was measured with a thermocouple probe positioned in the furcation area, capturing data continuously. The temperature of the ultrasonic inserts was monitored in real-time using a thermal imaging camera. Measurements were taken in a controlled environment without cooling for over 120 seconds. Statistical analysis was conducted using analysis of variance (ANOVA) and two-way ANOVA with repeated measures to evaluate temperature variations between groups and over time, with significance set at 5%.Results: In the external tooth surface temperature measurements, no significant differences were observed between the groups during the initial 15 seconds (p = 0.185) and 30 seconds (p = 0.067). However, significant differences emerged at 60 seconds (p = 0.025), 90 seconds (p = 0.024), and 120 seconds (p = 0.020), with the one-piece insert group demonstrating higher temperatures in the furcation region.

Furthermore, the recoloring subsequent to bleaching will be monitored.Methods: The study was conducted on 60 caries-free, unfilled, upper human incisors. The Freccia and Peters blood staining technique was employed, and four groups (n = 15) were identified: control, 35% hydrogen peroxide-treated, 37% carbamide peroxide-treated, and sodium perborate-treated groups. Color differences were measured using ΔE00, ΔWID, L*, a*, and b* values. To investigate tooth discoloration after bleaching, 10 unbleached teeth with three groups of 10 bleached teeth were compared by vine staining. The group of bleached teeth was restored immediately, another group waited one week, and the third group had sodium ascorbate applied and analyzed using one-way analysis of variance tests (p < 0.05).Results: Among the groups, carbamide peroxide exhibited the most significant whitening during the 6-day bleaching process, followed by hydrogen peroxide and sodium perborate. Subsequent examination of the wine recoloring of post-bleaching samples demonstrated that bleached teeth exhibited a heightened propensity for recoloration in contrast to unbleached teeth. Notably, sodium ascorbate treatments for hydrogen peroxide neutralization and the wait-and-restore approach were not statistically significant in terms of preventing recoloration.Conclusions: Sodium perborate is less effective and more time-consuming than hydrogen peroxide or carbamide peroxide for bleaching purposes. Carbamide peroxide is the most effective bleaching agent. The sodium ascorbate treatment and the wait-and-restore approach are ineffective in preventing recoloring. Bleached teeth have more discoloration than unbleached teeth.","PeriodicalId":21102,"journal":{"name":"Restorative Dentistry & Endodontics","volume":" ","pages":"e22"},"PeriodicalIF":1.5,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12415242/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144637887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
