This review examined whether placement of posts influences clinical behavior and survival probability of endodontically treated teeth (ETT).Methods: An electronic search, without time restrictions, for publications written in English was undertaken in PubMed, Scopus, and Web of Science. Terms related to four main components (endodontically treated teeth, fixed prosthesis, post restoration, and survival rate) were used for the database search strategies.Results: 57 studies met the inclusion criteria and were included in the qualitative analysis. Of the publications chosen for qualitative analysis, 17 clinical studies (11 prospective and 6 retrospective studies) were found to be suitable for quantitative analysis. These studies included 7,278 patients (7,330 ETT), with a mean age ± standard deviation (SD) of 45.46 ± 12.1 years. There was a statistically significant difference in survival rate between ETT with or without posts (P < 0.001).Conclusion: As compared with teeth with no posts, post placement on ETT may improve clinical performance and survival probability of endodontically treated teeth.","PeriodicalId":16646,"journal":{"name":"Journal of oral science","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142132999","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}

The prevalence of chamber canals, and the number, type and location (root third) of accessory canals were recorded. The relationships between arch side, sex and age were examined using chi-squared tests of association.

Variations in accessory root canal anatomy according to side, sex and age were evident. Chamber canals were identified in 10.9% of teeth. Accessory canals were found mainly in the apical third of most teeth in the sample, and distributed predominantly in the mesio-buccal root. Apical deltas were most prevalent in the mesio-buccal root, and their frequency decreased in the palatal and then finally the disto-buccal root.Conclusion: Accessory root canals were common in this population, and showed a diverse range of anatomy.

For evaluating transportation, pre- and post-preparation images were obtained under a stereomicroscope and superimposed with digital software. The distance between the inner and outer canal walls was measured. For the evaluation of debris extrusion, the samples were placed in Eppendorf tubes and instrumented using one of the four rotary files. The initial weight was subtracted from the post-instrumentation weight to determine the amount of extruded debris. The Kruskal-Wallis and Dunn multiple tests were performed.Results: For transportation, no significant difference was found between the XP-endo Shaper-Twisted File Adaptive systems and between Reciproc Blue-WaveOne Gold groups (P > 0.05). The XP-endo Shaper and Twisted File Adaptive techniques led to significantly less transportation compared to the other systems (P < 0.05).
