Previous issue date: 2013 / O objetivo deste estudo foi avaliar a influ?ncia da qualidade do tratamento de canal radicular (TCR), de fatores relacionados ? restaura??o coron?ria (RC), les?es por c?rie e par?metros cl?nicos periodontais no estado periapical de dentes tratados endodonticamente. Os pacientes foram tratados por estudantes de gradua??o na Cl?nica de Endodontia da Universidade Federal dos Vales do Jequitinhonha e Mucuri, entre o per?odo de 2004 a 2009. A reavalia??o cl?nica e radiogr?fica foi realizada entre Setembro de 2010 e Fevereiro de 2011. Foram coletados dados contidos nos prontu?rios odontol?gicos (idade, g?nero, dente tratado, estado periapical pr?-operat?rio, tipo de tratamento, t?cnicas de instrumenta??o e obtura??o empregadas, radiografia final da obtura??o e tipo de restaura??o coron?ria). Clinicamente, foram considerados fatores relacionados a sinais e sintomas endod?nticos, les?es por c?rie, RC e par?metros periodontais. Radiograficamente avaliou-se o estado periapical, les?es por c?rie, RC e pino intrarradicular. Os resultados foram analisados estatisticamente usando os testes qui-quadrado de Pearson, exato de Fisher, McNemar e regress?o log?stica bivariada e multivariada (p<0,05). Foram reavaliados 122 pacientes ap?s per?odo de acompanhamento de 12 a 66 (37,7?16,4) meses, e estes apresentaram 154 dentes tratados endodonticamente. Os dados foram organizados e analisados conforme o desenho de estudo e vari?veis estudadas, sendo apresentados em dois artigos cient?ficos. No geral a taxa de sucesso cl?nico-radiogr?fico do TCR foi de 73,4%. No estudo longitudinal observou-se frequ?ncias elevadas de obtura??es perfeitas (41,6%) e satisfat?rias (46,1%) e frequ?ncia reduzida de obtura??es deficientes (12,3%). A qualidade das obtura??es e das restaura??es coron?rias, analisadas isoladamente, influenciou no sucesso cl?nico-radiogr?fico (p<0,05); a presen?a de pr?via les?o periapical (OR=10,24; IC=3,15-33,22) foi o fator decisivo para o insucesso do tratamento. No estudo transversal observou-se que a presen?a de les?es por c?rie (p=0,017), sangramento gengival ? sondagem (p=0,043) e mobilidade dent?ria (p=0,022) foram os fatores associados ao insucesso do TCR. As outras vari?veis relacionadas ?s les?es por c?rie, RC, qualidade da obtura??o e par?metros cl?nicos periodontais, n?o influenciaram no insucesso do tratamento (p>0,05). Concluiu-se que, no estudo longitudinal, o pr?vio estado periapical foi o principal fator que influenciou o progn?stico do TCR e, no estudo transversal, a presen?a de les?es por c?rie e aspectos periodontais influenciaram negativamente no estado periapical dos dentes tratados endodonticamente. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Odontologia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2012. / ABSTRACT The aim of this study was to evaluate the influence of root canal treatment (RCT) quality, factors related to the coronal restoration (CR), carious lesions and periodontal clinical parameters in the periapical status of endodontically treated teeth. The patients were treated by undergraduate students at the Clinic of Endodontics, Federal University of Jequitinhonha and Mucuri Valleys (UFVJM) in the period between 2004-2009. The clinical and radiographic recall was performed between September 2010 and February 2011. Data were collected in records dentistry (age, gender, treated tooth, periapical status preoperative, type of treatment, instrumentation and obturation techniques, final radiography of the filling and the type of coronal restoration). Clinically, factors related to carious lesions, CR and periodontal parameters were considered. Radiographic parameters were evaluated the periapical status, carious lesions, CR and cast post. The results were statistically analyzed using Pearson chi-square, Fisher?s exact and McNemar tests, bivariate and multivariate logistic regression (p<0.05). A total of 122 patients were reassessed after a follow-up of 12-66 (37.7?16.4) months which had 154 endodontically treated teeth. Data were organized and analyzed according to the study design and variables, and are presented in two papers. Overall, the success rate of the RCT was 73.4%. In the longitudinal study it was observed a high frequency of perfect (41.6%) and satisfactory (46.1%) fillings and a reduced frequency of deficient (12.3%) fillings. The quality of fillings and coronal restorations, when analyzed individually, influenced the clinical and radiographic success (p<0,05); preoperative periapical lesion was the main factor for the treatment insuccess (OR=10.24, CI=3.15-33.22). In cross-sectional study it was observed that the presence of carious lesions (p=0.017), gingival bleeding (p=0,043) and tooth mobility (p=0.022) were the factors associated with insuccess of RCT. The other variables related to carious lesions, CR, quality of fillings and periodontal clinical parameters, did not influence the insuccess treatment (p>0.05). In conclusion, the prior periapical status was the main factor affecting the prognosis of the RCT in the longitudinal study and, in the cross-sectional study the presence of carious lesions and periodontal aspects negatively influenced the periapical status of endodontically treated teeth.
