ANOVA followed by Bonferroni post-hoc tests were used for analysis. The amount of debris extrusion was significantly higher in PTU, which was affected by the irrigation solution temperature (p < 0.05).

The International Association of Dental Traumatology (IADT) suggests that cone-beam computed tomography (CBCT) should be considered, when conventional radiographs provide 'insufficient' information for diagnosis and treatment planning. Considering that CBCT can divulge additional information, it would be beneficial to have a clinically pertinent three-dimensional classification for TRF. The proposed alphanumeric classification includes the traumatised tooth number, describes the number of TRF, the facial and lingual location of each fracture line on the anatomic root, and its position relative to the crest of the alveolar bone. Further, diastasis, displacement of the coronal fragment and status of the alveolar bone at the site of TRF are also documented. This comprehensive classification system would provide a standard format for reporting, aid in referral communication and can be applied for future outcome studies on TRF.</p>","PeriodicalId":55581,"journal":{"name":"Australian Endodontic Journal","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141473003","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}
