Avaliação da qualidade dos tratamentos endodônticos em centros de especialidades odontológicas da Grande Natal - RN / Quality of endodontic treatments at dental specialty centers in the Greater Natal, RN, Brazil

RESUMO

Objetivo: Avaliar a qualidade técnica dos tratamentos endodônticos realizados em Centros de Especialidades Odontológicas (CEOs) da Grande Natal/RN no período de 2006 a 2008. Método: Estudo transversal com amostra de 282 dentes submetidos a tratamento endodôntico há pelo menos um ano. Os participantes da pesquisa foram avaliados através de exames clínicos e radiográficos. Os dentes tratados endodonticamente foram examinados por uma especialista em endodontia, que comparou e analisou as radiografias realizadas ao final do tratamento e anexadas ao registro do paciente no CEO com tomadas radiográficas atuais. Os dados coletados foram apresentados de forma descritiva através de números absolutos, percentuais e médias. Para a determinaçÆo da associaçÆo entre as variáveis independentes e as variáveis dependentes realizou-se análise bivariada através do teste do qui-quadrado e exato de Fisher. Resultados: Dos elementos dentários examinados 79,8% apresentaram-se sem lesÆo periapical, 84,4% sem dor, 8,2% fraturados e 3,2% extraídos. As obturaçães dos canais encontravam-se adequadas em 81,2%. Com relaçÆo ao limite longitudinal, 135 (47,9%) das obturaçães foram consideradas com limite ideal, 50 (17,7%) sobreobturados e 88 (31,2%) subobturados. A persistência de lesÆo periapical esteve associada ao estado periapical inicial (p<0,05). ConclusÆo Os tratamentos endodônticos que foram realizados nos Centros de Especialidades Odontológicas possuem uma adequada qualidade técnica, resultando no sucesso da terapia endodôntica realizada nestes Centros...

ABSTRACT

Objective: To evaluate the technical quality of the endodontic treatments performed at Dental Specialty Centers (DSC) in the Greater Natal, RN, Brazil, between 2006 and 2008. Method: A cross-sectional design was used with a sample of 282 teeth with endodontic treatments completed at least 1 year before the study. The participants were subjected to clinical and radiographic. The endodontically treated teeth were examined by an endodontist who compared and analyzed the radiographs taken at the end of the treatment as part of the patient?s documentation at the DSC with the current radiographs. The collected data were presented by descriptive statistics in absolute numbers, percentages and means. Association among the independent and dependent variables was made by bivariate analysis with the chi-square and Fisher?s exact tests. Results: As much as 79.8% of the teeth did not present periapical lesion, 84.4% had no associated painful symptomatology, 8.2% were fractured and 3.2% had been extracted. The root fillings were adequate in 81.2% of the teeth. Regarding the apical limit of root canal filling, adequate filling was observed in 135 teeth (47.9%), overfilling in 50 (17.7%) and underfilling in 88 (31.2%). Persistence of periapical lesion was associated with the initial stage of apical periodontitis (p<0.05). Conclusion: The endodontic treatments performed at the DSC have adequate technical quality, resulting in success of the root canal therapy...
