Determining the Optimal Obturation Length: A Meta-Analysis of LiteratureMichelle A. Schaeffer, DDS, MPH, Robert R. White, DMD, and Richard E. Walton, DMD, MSAbstractThe purpose was to aid in Determining termination ofinstrumentation and Obturation . A meta-analysis wasconducted as to success/failure of different obturationlengths. Inclusion criteria were (a) minimum follow-upof 2 yr, (b) data on Obturation length , (c) definition ofsuccess/failure, (d) available data on success/failure, (e)radiographic evaluation. Correlations were made as tosuccess/failure as related to length of Obturation fromthe apex. When comparing group A (obturated 0 1 mmfrom apex) versus group C (obturated past apex) usingthe DerSimonian and Laird estimates, group A showeda marginally better (p ) success rate than groupC by Group A had better success than group B(obturated 1 mm short); the difference was insignif-icant.
