ABSTRACT
The aim of this study was to monitor nonsurgical and surgical root canal treatment (RCT) of teeth with primary and secondary infections and apical periodontitis (AP). This prospective clinical study comprised the treatment of 80 patients with primary and persistent secondary infections and AP. Of this initial sample, forty patients did not return. Periapical index using cone beam computed tomography scans (CBCTPAI) was used to aid diagnosis, planning and to determine the better therapeutic strategy. Twenty patients (26 teeth) diagnosed with primary infection and AP received conventional RCT and were followed up for 10 to 36 months. Twenty patients (31 teeth) diagnosed with persistent secondary infection were submitted to periapical surgical and followed up for 6 to 30 months. The results showed RCT successful in 19/26 cases with complete AP healing (5/26 with partial repair) in 10-36 months of follow up. For the surgically managed cases, effectiveness of surgical therapy was detected in 10/31 cases with complete healing (10/31 cases with partial repair) within 6-30 months follow up. The return of patients for clinical and radiographic follow-up, and obedience to the proposed time period was very short from ideal. The levels of success in both therapeutic protocols were high. RCT failures were detected even with rigorous standard clinical protocols.
RESUMO
O objetivo do estudo foi monitorar tratamentos de canais radiculares (TCR) convencionais e com auxílio de cirurgia periapical. Este estudo prospectivo constituiu de 80 pacientes portadores de infecções primárias e secundárias persistentes e periodontite apical (PA). O índice periapical utilizando tomografia computadorizada de feixe cônico (CBCTPAI) foi utilizado como auxiliar no diagnóstico, planejamento e para determinar a melhor estratégia terapêutica. Apenas 40 pacientes retornaram para o TCR. Em 20 pacientes (26 dentes) com diagnósticos de infecções primárias e PA foram feitos TCR convencionais e monitoramentos por 10 a 36 meses. Em 20 pacientes (31 dentes) com diagnósticos de infecções secundárias persistentes foram submetidos a procedimentos cirúrgicos e acompanhamentos durante 6 a 30 meses. Os resultados mostraram TCR bem sucedidos em 19 de 26 casos, com curas completas das PA (5 de 26 com reparação parcial) em controles de 10 a 36 meses. Para os casos de tratamentos cirúrgicos foram detectadas eficácias das terapêuticas cirúrgicas em 10 de 31 casos com curas completas (10 de 31 casos com reparação parcial) em controles de 6 a 30 meses. O retorno dos pacientes para controle clínico e radiográfico e a obediência ao período de tempo proposto está muito aquém do ideal. Os níveis de sucesso em ambos os protocolos terapêuticos se mostraram elevados. Fracassos no TCR foram detectados mesmo utilizando protocolo clínico com rigoroso padrão.
