Microbiolgical analysis of root canal flora of failed pulpectomy in primary teeth

The primary objective of pulpal treatment is to preserve the integrity and health of the oral tissues (Fuks, 2000). Pulpectomy is indicated in teeth that show evidence of chronic inflammation or necrosis in the radicular pulp, with or without periapical or furcation pathology. The goal of this treatment is to maintain primary teeth that would otherwise be lost. When teeth are treated by root canal therapy under aseptic conditions and according to accepted clinical principles, generally the success rate is high. Most of the clinical studies have reported success rate of 65 100% following this treatment (Chiba, 1981; Holan and Fuks, 1993).
