The impact of radiation on the fracture resistance (FR) of endodontically treated teeth has piqued the interest of dental researchers. Bioceramic sealers like CeraSeal have shown promising dentin bonding and sealing abilities, but there is limited data on their FR compared to traditional resin-based sealers like ADSEAL. Therefore, the aim of this study was to investigate the effect of therapeutic radiation doses on the FR of root canal-treated teeth filled with gutta-percha and two sealers. Materials and Methods: Ninety extracted mandibular premolars were divided into experimental and control groups. Each group was further subdivided into subgroups with and without irradiation (n=15) and obturated with either ADSEAL or CeraSeal. The FR of each group was tested using a Universal Testing Machine. Statistical analyses included independent t-tests for matched groups and One-Way ANOVA followed by Tukey’s Post Hoc test for multiple comparisons (p < 0.05). Results: Before irradiation, both sealers significantly increased the FR compared to the control group. CeraSeal exhibited the highest FR, followed by ADSEAL. After irradiation, all groups showed a significant reduction in FR, with CeraSeal demonstrating the least reduction. Conclusions: Regardless of the sealer used, irradiation decreases the FR in root canal-treated teeth. CeraSeal outperformed ADSEAL in maintaining tooth strength after irradiation.","PeriodicalId":11504,"journal":{"name":"Egyptian dental journal","volume":"54 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141716043","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}

Participants were divided into two equal groups (n=7). Group 1 where 25 grams of intrusive force were applied, Group 2 where 100 grams of intrusive force were applied. Via a paper visual analogue scale (VAS) distributed to each patient after the end of the three months of intrusion to assess their pain score. Results: For patients undergone 25 grams intrusive force, the mean VAS score was 1.8±0.4 with a median 2.0 and interquartile range (IQR):(2.0 to 2.0) vs. 4.4±0.5 with a median 4.0 and IQR:(4.0 to 5.0) for patients undergone 100 grams, indicating a statistically significant increased pain score among patients subjected to the higher intrusive force (absolute mean difference = 2.6, p <0.001).

Methods: A total of 50 restorations, 25 overlays (group O) and 25 endocrowns (group E), were fabricated to restore root canal treated molars. All restorations were fabricated from lithium disilicate (IPS e. max CAD). After tooth preparation, digital impression was done followed by designing, milling and cementation of the restorations. Evaluation was done every 3 month for 12 months by three independent assessors using Modified USPHS criteria. Statistical analysis of collected data was performed with SPSS 20® , Graph Pad Prism® and Microsoft Excel 2016. Results: Regarding fracture and marginal adaptation, all restorations in both groups had Alpha score (100%); at base line and during the follow-ups. While for retention, all restorations in both groups had Alpha score (100%); at base line, after 3, 6, and 9 months. However, after 12 months, there was insignificant difference between both groups (P=0.08) as Alpha was (87, 100%) while Charlie was (13, 0%) regarding Group O & E respectively.

Materials and methods: Fourteen 3D-printed resin and 14 milled PMMA discs were divided into two groups (n=7) based on pH media (Coffee and Fanta) for immersion. At two-time immersion intervals (1 and 7 days), the surface roughness using a non-contact profilometer and color stability using a spectrophotometer were tested. Results: Milled groups showed higher surface roughness at the baseline in both immersions and after 7 days immersion in coffee (0.2908±0.0015). After 7 days in Fanta, 3D printed group showed higher surface roughness (0.2921±0.0013). Considering color stability, after 1-and 7-days immersion, 3D printed group showed a higher color change (ΔE) in coffee (6.15±1.94) than milled group (3.97±1.24). Milled group showed a higher ΔE significance in Fanta (6.17±2.48) than 3D printed group (3.35±1.38). Conclusion: The surface roughness and color stability of interim restorations were affected by the material, construction technique, and different pH beverage consumption. After seven days, Coffee increased the milled interim surface roughness, whereas Fanta increased it in 3D printed restorations.
