To ensure the success of the endodontic tratment, is important to consider the respect by original root canal anatomy. AIM: Evaluate the maintenance of the original canal anatomy when comparing three different rotary systems, ProTaper UniversalTM, ProTaper NextTM and Protaper GoldTM. MATHERIALS AND METHODS: A quantitative analysis was made by measuring the canal with of 36 samples, distributed by three groups of twelve samples each (Group A -ProTaper UniversalTM, Group B - ProTaper NextTM, Group C Protaper GoldTM, by superimposed images of pre and post instrumentation using Rhinoceros Software. In the qualitative analysis, blinded examiners evaluated three images from each group and refer the presence or absence of rectifications in the coronal and apical curvatures, as well as the presence of significant apical transportation. The statistical analysis was obtained using Kolmogorov-Smirnov test, Mann-Whitney post hoc multiple comparisons U test and One-Way ANOVA, with a significance of p<0,05. RESULTS: Considering the inner side of both curvatures, differences between files are statistically significant (p<0,05), where the ProTaper UniversalTM system is responsible for a bigger widening, while ProTaper GoldTM presents the smaller mean value. DISCUSSION AND CONCLUSION: It might be assumed that ProTaper GoldTM was the rotary system that has more respect for original canal anatomy. Higher flexibility might be the predominant propriety responsible by these results. ProTaper Universal TM was the system that originated the greatest modification of the original canal, presenting a significant tendency to straightened apical curvature.Ginjeira, António Manuel Pinto 1958Repositório da Universidade de LisboaNeto, Filipa dos Santos2017-06-29T00:30:11Z201520152015-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/25513TID:201271257enginfo:eu-repo/semantics/embargoedAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T16:15:00Zoai:repositorio.ul.pt:10451/25513Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:42:22.692570Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
