In the present study 80 freshly extracted permanent, single canaled maxillary anterior teeth and mandibular premolars were selected. The apical leakage was assessed in relation to different root canal obturation techniques using 2% aqueous solution of methylene blue dye and the measurement was done by stereomicroscope.
In this study all the teeth exhibited some amount of apical leakage. Low temperature thermoplasticized gutta percha technique exhibited the least amount of leakage when compared to all the other techniques used. Lateral condensation was considered the second best root canal obturation technique. Single cone condensation method (control group) exhibited maximum amount of leakage compared to all the other root canal obturation techniques.
