Warm Vertical Compaction Versus Lateral Compaction For Root Canal Obturation, Ahmed A. Madfa
Ahmed A. Madfa
Objectives: This study compared warm vertical compaction with lateral compaction for obturating root canals with either a polymer-based resin system or gutta-percha. Quality of obturation was evaluated by (i) analysis of the canal area occupied by filling core materials, sealers and voids at three cross-sectional levels and (ii) SEM examination. Methods: Single canals in 64 mandibular premolars were instrumented, irrigated and divided into four equal groups. They were root filled as follows: lateral compaction/resin (RealSeal™, SybronEndo) (LC/R), lateral compaction/gutta-percha with AH Plus™ (LC/GP), warm compaction/resin (WC/R) and warm compaction/gutta-percha (WC/GP). One specimen from each group, randomly chosen for SEM examination, …
