title: A comparative evaluation of apical linear dye penetration of Glass ionomer based sealers with conventional root canal sealers. An in vitro study.
abstract: This study was done to evaluate the clinical practicality of a new Water mixable Glass ionomer root canal sealer with conventional type 11a Glass ionomer cement, if used as a sealer, along with Zinc oxide Eugenol and Calcium Hydroxide containing sealers. Forty freshly extracted single rooted Maxillary incisors were selected for the study. Ten teeth were assigned for each sealer group. Access cavity was prepared, wording length determined, modified step-back preparation and obturation of the root canal done with lateral condensation technique. Assigned groups were Group 1--Type 11a Glass ionomer cement, Group 11--Mixed Tubliseal, Group 111--Mixed Sealapex, Group IV--Endion. Micro leakage Values were assessed by the amount of linear dye penetration in to the apical pulp space. Statistical analysis was done with one way analysis (ANOVA), using Fisher's 'F' test and students unpaired 't' test. Seal apex exhibited the least micro leakage value and found to be the best sealer among the four sealer groups.
