Resumo
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.
