Twenty teeth underwent artificial caries induction. The remaining five teeth with sound dentin serve as the positive control. The twenty demineralized teeth were subdivided into four groups (n = 5): carious dentin without restoration (negative control [NC]), carious dentin restored with CSC (Biodentine, Septodont), carious dentin restored with GI (Fuji IX, GC Corporation), and carious dentin restored with RMGIC (Fuji II LC, GC Corporation). Following restoration, the specimens were stored in artificial saliva for 7 days. The elastic modulus was evaluated by a nanoindentation test. The mineral composition was analyzed by scanning electron microscopy-energy-dispersive X-ray spectroscopy (SEM-EDX), and the mineral composition at the dentin-material interface.Results: CSC had a higher modulus of elasticity compared to GI, RMGI, and NC groups (p < 0.05). Higher calcium and phosphorus content was observed under CSC restorations, as indicated by SEM-EDX examination, which may lead to better remineralization.Conclusions: Compared to GI and RMGI, CSC showed the best remineralization and mechanical reinforcement in caries-affected dentin, indicating CSC for use in minimally invasive restorative dentistry.","PeriodicalId":21102,"journal":{"name":"Restorative Dentistry & Endodontics","volume":" ","pages":"e37"},"PeriodicalIF":1.5,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12707560/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145513272","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}

The setting time was measured with Gilmore needles, and microhardness was assessed using a Vickers tester after 3 days. Welch's analysis of variance and Games-Howell post hoc tests were used for statistical analysis.Results: The sealer type and environmental conditions significantly influenced setting time and microhardness (p < 0.001). The initial and final setting times were the shortest in the unsoaked samples. For Endoseal MTA and One-Fil, the unsoaked condition exhibited significantly shorter setting times than the soaked conditions. Well-Root ST exhibited significantly longer setting times in acidic conditions. Surface microhardness was highest in the unsoaked group (p < 0.001). Among the soaked groups, the phosphate-buffered saline-soaked group had the lowest hardness for Endoseal MTA, whereas the pH 5-soaked group exhibited the lowest hardness for One-Fil and Well-Root ST. Endoseal MTA consistently demonstrated a lower microhardness than the other sealers (p < 0.001).Conclusions: Moisture, pH, and solution chemistry influenced the setting time and microhardness of premixed calcium silicate sealers.

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}

A significance level of 0.05 was applied to determine statistical differences.Results: The addition of AgNPs decreased the carbonate peak intensity in XRD and FT-IR. The rod-like morphology of MTA was changed to a flake-like morphology with the addition of AgNPs. Antibacterial efficacy enhanced proportionally with the augmentation of AgNPs concentration.Conclusions: The creation of rapid admixture of MTA and AgNPs during chairside use in clinical settings can deliver beneficial characteristics of enhanced morphological features favoring mineralization and profound antibacterial effects to overcome the challenges associated with root canal treatment and pulp capping.","PeriodicalId":21102,"journal":{"name":"Restorative Dentistry & Endodontics","volume":"50 3","pages":"e30"},"PeriodicalIF":1.5,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12415241/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144993344","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}
