Comparative analysis of simulated root canal anatomy after different preparation systemsSaúde oralMateriais dentáriosTeses de mestrado - 2017Domínio/Área Científica::Ciências Médicas::Medicina ClínicaTese de mestrado, Medicina Dentária, Universidade de Lisboa, Faculdade de Medicina Dentária, 2017INTRODUCTION: Evolution of endodontic shaping instruments has occurred over time, leading to improved materials, reduced procedural errors and preparation techniques with only minor alterations to the canal morphology. Although these new methods and instruments improvements, maintain the original canal anatomy still is a challenge. OBJECTIVES: The purpose of this study is to compare the shaping abilities of two different system files: Reciproc® blue, a reciprocating NiTi single file and iRace/iRace Plus, a continuous rotary file system. MATERIAL AND METHODS: Twenty simulated root canals were prepared and randomly divided into 2 groups (n=10): group A, Reciproc® blue and group B, iRace/iRace Plus file system. Standardized pre and postoperative images were taken using a digital camera, superimposed and then recorded. Transportation at coronal and apical curvatures was measured. A qualitative analysis with blinded examiners was done. The statistical analysis was obtained using Shapiro-Wilk test and Mann-Whitney U test, with a significance of p<0,05. RESULTS: Reciproc® blue causes greater resin material removal at the level of coronal curvature, and iRace/iRace Plus system at the apical curvature level (statistically significant differences). Reciproc® blue causes more transportation on the inner and outer margins of coronal curvature and iRace/iRace Plus system is responsible for a greater transportation on the outer margin of the apical curvature (statistically significant differences). The clinician’s expertise caused more evaluation differences in Reciproc® blue system but the great majority indicates that exist a maintenance or few changes of the original shape of the canal, and iRace/iRace Plus system group presents maintenance of the original shape of the canal. CONCLUSION: Under the limitations of this study and based on the results obtained, although Reciproc® blue caused greater resin material removal at the level of coronal curvature and iRace/iRace Plus system at the apical curvature level, there is no statistically significant difference between the two files systems for total transportation. Evaluating the maintance of the original anatomy, iRace/iRace Plus system was the file system which best maintained the original anatomy of the S-shaped canal.Ginjeira, António Manuel Pinto, 1958-Repositório da Universidade de LisboaCoelho, Susana2017-11-02T16:45:34Z201720172017-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/29562TID:201737191enginfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T16:21:41Zoai:repositorio.ul.pt:10451/29562Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:45:24.889447Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
