Clinical evaluation of permanent molars diagnosed by irreversible pulpits with apical periodontitis treated by MTA pulpotomy

Background: This study examined the clinical effects of mineral trioxide aggregate (MTA) pulpotomy for permanent molars with caries-derived pulpitis with symptomatic apical periodontitis. Methods: Based on symptomatic apical periodontitis or not, 52 permanent molars with pulp exposure due to caries were divided into 29 in the non-symptomatic apical periodontitis group and 23 in the symptomatic apical periodontitis group. Results: Regardless of the root development degree, both groups were treated with different depths of pulpotomy according to pulp status and bleeding. Clinical and radiological examinations were scheduled for follow-up after 1, 3, 6 and 12 months to undergo clinical and radiological examination. A success rate of 96.6% was achieved in the non-symptomatic apical periodontitis group; 91.3% was achieved in the symptomatic apical periodontitis group. There was no significant difference between both groups (χ2 = 0.65, p = 0.42). Conclusions: MTA pulpotomy is an effective treatment for caries-derived pulpitis in permanent molars with symptomatic apical periodontitis, offering a new approach for clinical treatment.
