Apical seal helps preventing apical leakage following apicectomy.
To investigate the influence of apicectomy modalities on apical seal of root canals obturated with resin-based system.
Root canals of 60 extracted premolars were prepared and obturated in 6 groups using RealsealSE sealer-points system. The teeth were divided into 6 equal groups according to apicectomy procedures. Group1 (obturation, immediate apicectomy, glass-ionomer retro-filling), Group2 (obturation, apicectomy after 24 hours, no retro-filling), Group3 (obturation, immediate apicectomy, light-curing of the sealer at the cut-surface), Group4 (obturation, immediate apicectomy, no apical-sealer light-curing), Group5 (apicectomy, obturation, apical-sealer light-curing), Group6 (apicectomy, obturation, light-curing of apical sealer coat). Specimens in all groups were subjected to dye leakage and longitudinal sectioning test. The collected data were statistically analyzed.
Both G1 (control) and G6 recorded comparable leakage possibility that was the lowest among test groups. Leakage values of groups 3 and 5 were also comparable and lower than groups 2 and 4. Leakage values of group 4 were the worse among all groups.
Apical sealing with a self-etch adhesive sealer coat is an acceptable alternative to retrograde filling in resin-obturated canals. Light-curing of the sealer exposed following apicectomy might improve the apical seal.
