Healing rate and post-obturation pain after single- versus multiple- visits endodontic therapy of infected root canals
Zyad Al-Sayed Mohammad;
Abstract
This study was conducted in order to compare healing rates of periapical lesions and severity of post-obturation pain after single- versus multiple- visits endodontic therapy of infected root canals. Forty patients participated in this study, in which their maxillary or mandibular anterior teeth diagnosed with chronic (asymptomatic) apical periodontitis and large periapical radiolucency, not less than 1 cm diameter in the periapical radiograph.
Chemo-mechanical preparation of root canals was performed according to standardized procedures, then obturation of root canals was done in the same visit for the single visit group patients, and intra-canal medications were placed in root canals of the two visits group patients. Intra-canal medications were removed from root canals one week later, and obturation of these root canals was performed. The peri-radicular surgery was performed 72 hours after obturation of the root canals (in both single visit and two visits groups), in which the pathological tissue was removed, apicectomy and retrograde filling or root canals was performed.
Comparisons between single visit and two visits root canal treatment protocols were performed regarding severity of post-obturation pain, levels of periapical inflammatory mediators (IL-1β and PG-E2), and healing rate of the accompanied periapical lesions.
Severity of post-obturation pain was evaluated using a Verbal Analogue Scale for 4, 24, 48 and 72 hours after the endodontic treatment completion. Levels of periapical inflammatory mediators (IL-1β and PG-E2) were measured by processing the surgically
