MTA was removed with the acids, plus ultrasonic tips and rotary files. Outcomes were measured as pre- and post-operative weight differences, luminance differences and working time to regain length or form ledges. Weight differences varied significantly - citric acid was highest; hydrochloric acid was lowest and others were not statistically different from each other. Luminance did not differ significantly between groups but varied significantly with distance from the apex - hydrochloric acid and carbonic acid were lowest at 1 mm from the apex. Working times differed significantly - hydrochloric acid took longer than other acids except citric acid. Overall, the most effective acid was citric acid. The least effective was hydrochloric acid.</p>","PeriodicalId":55581,"journal":{"name":"Australian Endodontic Journal","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143694339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, specialist referral is frequently recommended. Guided endodontics emerges as a promising alternative that facilitates access to calcified canals. This scoping review assesses the influence of the operator's experience on the accuracy and efficiency of guided endodontic access. A search across eight electronic databases until August 4, 2024, identified 999 records, from which 31 articles were analysed. These studies evaluated the association between operator experience and guided access outcomes. Despite variability in guide models and evaluated parameters, operators of different experience levels demonstrated similar performance. Thus, guided endodontics is a precise and efficient technique, beneficial even for less experienced operators. The primary limitations stem from the scarcity and methodological limitations of existing studies.</p>","PeriodicalId":55581,"journal":{"name":"Australian Endodontic Journal","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143694353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
