Whether there is periapical pathosis or not, it is advised that all restorative and obturation materials be removed from all roots. Selective root retreatment, a new therapeutic strategy, allows retreatment to be restricted to a single root or multiple roots exhibiting periapical pathosis. To address the issues, \"guided endodontics,\" a unique guided technique for the preparation of apically extended access cavities, was introduced.Materials and methods: In this in vitro experimental study, 22 freshly extracted two-rooted maxillary first premolars were selected and divided into two groups (n = 11). Pretreatment cone-beam computed tomography imaging of all teeth was performed. Root canal treatment was performed for all samples followed by postendodontic composite restorations with the occlusal stamp technique. Then targeted endodontic retreatment (TER) was done with the conventional method and guided method respectively. The tooth substance loss was measured and evaluated using Ez3D-i-3D-software (VATECH) and work precision was determined by calculating the dentinal loss. Statistical data analysis was done by Independent t-test for substance loss measurement and Chi-square test was used to measure the dentinal loss.Results: TER with conventional method showed significantly higher substance loss with t = 4.591 (P < 0.05) and significantly higher dentinal loss measured in conventional method (P < 0.05).Conclusion: In comparison to traditional TER, TER using a customized bur and three dimensions (3D)-guide results in much less substance loss. The dentinal loss was much lower in 3D-guided approach.","PeriodicalId":38892,"journal":{"name":"Journal of Conservative Dentistry","volume":"26 2","pages":"221-225"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10190081/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9851841","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}

Aim: The aim is to evaluate and compare calcium ion release and pH change using NCH with different vehicles as intracanal medicament. Subjects and Methods: Sixty freshly extracted premolars were decoronated at the cementoenamel junction level and the length was standardized. Canals were enlarged to F3 size using protaper rotary system. The samples were divided into three groups (n = 20), namely NCH + distilled water (Group 1), NCH + propylene glycol (Group 2), and NCH + chitosan (CT) (Group 3). Each sample was suspended in 6 ml of distilled water using silicone putty with only the apical third of the roots immersed. The pH and calcium ions were assessed at 24 h, 7 days, 15 days, and 30 days using a pH meter and ultraviolet spectrophotometer, respectively. Statistical Analysis: Comparison of mean calcium release and pH change was made using Kruskal–Wallis ANOVA with post-hoc Dunn's test. The level of significance was set at 5%. Results: A significant difference was seen in the calcium ion release and pH change among the three groups at 24 h, 7 days, 15 days, and 30 days. Conclusions: NCH mixed with propylene glycol showed alkaline pH and adequate release of calcium ions till 30 days. NCH mixed with CT exhibited a high pH at the end of 30 days. Both combinations proved their efficacy as intracanal medicaments.","PeriodicalId":38892,"journal":{"name":"Journal of Conservative Dentistry","volume":"26 1","pages":"47-51"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10003273/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9095515","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}
