This work proposes a standardized workflow for ECR treatment considering the 3D-classification of the lesion by Patel and assesses its clinical applicability to 7 preliminary clinical cases. \u0000Summary: ECR cases were detected from medical and dental history, clinical data and a conventional radiography; a Cone Beam Computed Tomography (CBCT) with a small field of view (FOV) was performed too. A both 2D and 3D-classification was applied on each resorption. After studying better the clinical aspect, especially the accessibility of the lesion, the restorability of the tooth was assessed and the approach was decided between external repair, with or without endodontic treatment, or internal repair. Reparative tissue was removed and the defect was managed through new generation composite resins, mineral trioxide aggregate (MTA) or other cements. A pulp capping was performed in one case and a canal treatment in the others. Clinical and radiographic checks assessed both quality and adequacy of the treatments immediately and over time. \u0000Key learning points: \u0000 \u0000A standardized workflow could be useful for ECR treatment; \u0000CBCT is essential for determination of ECR extension and an appropriate treatment planning; \u0000ECR management should be conservative, but should also remove the reparative tissue; \u0000ECR management could be performed within one or two appointments; \u0000a follow-up is required to evaluate the treatment over time. The main outcome is the survival of the element, the secondary outcomes are the absence of resorption progression, no symptoms and healthy periodontal values.","PeriodicalId":42221,"journal":{"name":"Giornale Italiano di Endodonzia","volume":"46 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90783515","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 teeth were randomly divided into two main test groups (n=48) and two control groups, one positive and one negative (n=4). In one test group, Ca(OH)2 was used; in the other test group, no dressing was placed within the canal. Samples in each test group - with or without Ca(OH)2 dressing - were randomly divided into two subgroups. In one subgroup, AH 26 sealer was used and in the other one, TF BC sealer was used. The specimens with Ca(OH)2 were kept at 37 °C in 100% humidity. A dye penetration technique was used to evaluate the leakage. The data were analyzed by Kolmogorov-Smirnov, Kruskal-Wallis, Mann-Whitney U, and Fisher exact tests. \u0000Results: The mean microleakage in the subgroups filled with TF BC sealer, with or without Ca(OH)2, was significantly greater than that in the subgroups filled with AH 26 sealer. In addition, the microleakage of the TF BC specimens with Ca(OH2) was significantly higher than the microleakage of TF BC specimens without the dressing (P<0.001). \u0000Conclusion: The findings of this study showed that use of Ca(OH)2 as an intracanal dressing negatively affected the sealing potential of TF BC.","PeriodicalId":42221,"journal":{"name":"Giornale Italiano di Endodonzia","volume":"63 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74405011","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 three cases presented different degrees of complexity, related to the extension of the resorption. In two cases, root canal treatment was performed and internal management of the resorptive lesion was accomplished. In a third case, with a more severe extension of ECR, surgical approach with flap elevation was done to access the resorptive defect.

This case report presents the importance of a correct 3D diagnosis and treatment planning in maintaining teeth with ECR. \u0000Key learning points: \u0000 \u0000ECR is a pathologic root resorptive process with an unclear aetiology.

After specimen’s preparation, the initial dentin microhardness (H0) was measured with a Vickers indenter, on the coronal surface, at 150 µm and 500 µm from the root canal lumen. Next, the specimens were randomly distributed into three groups (n=10), according to the different irrigation protocols: 1% NaOCl; 1% NaOCl + 17% EDTA; and 5% NaOCl. After irrigation, the hardness measurement was repeated (H1), in another quadrant. Then, Ca(OH)2 dressing was applied and left for 30 days, until it was removed and a new microhardness measurement (H2) was made, in a third quadrant.

Methodology: The research question was developed using the PICO methodology and studies were identified from three electronic databases in Medline, Scopus, and EBSCOhost (Dentistry; Oral Sciences Source) since inception up to November 2019. The title and abstract of the selected articles were independently reviewed by two reviewers based on the specified inclusion and exclusion criteria and extracted the data using the data extraction form. The quality of selected in vitro studies was appraised using revised Cochrane Risk of Bias tool.Results: Sixteen studies satisfied the inclusion criteria and were included in this systematic review. Due to the lack of homogeneity in the data, meta-analysis could not be conducted. The quality of the evidence was \"low\", since every study had at least three questions related to high risk of bias. Different laboratory tests and protocols were used, their results were contradicting even for studies using the same laboratory tests and quality of evidence was found to be low. No study provided strong evidence, twelve studies provided moderate evidence, three studies provided limited evidence and one study provided conflicting evidence. The research question could not be meaningfully addressed. Conclusions: No difference was observed in the antimicrobial efficacy of Sealapex and AH-plus root canal sealers against Enterococcus faecalis. There was an identification of poor quality relevant studies with contradicting results that indicates the need for development of standardized protocols for future in vitro studies.","PeriodicalId":42221,"journal":{"name":"Giornale Italiano di Endodonzia","volume":"1 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2020-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79712051","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 inter-evaluator reliability for microcrack detection using ESEM had a Kappa value of 0.98 (p<0.001), while the intra-evaluator reliability had a Kappa value of 0.99 (p<0.001).
