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
