Objective: The aim of this in-vitro study was to compare dentinal adaptation of conventional obturating material and GuttaFlow in young permanent teeth of child patients. Materials and Methods: Ten young permanent anterior teeth with closed foramen were selected for the study. Root canal preparations were carried out using a step back technique. The canal was alternately irrigated with 5.25% sodium hypochlorite solution and 17% EDTA and normal saline. After root canal preparation specimens were randomly divided into two groups (n=5). GROUP "A": Obturated with zinc-oxide eugenol sealer and gutta-percha cone using cold lateral obturation technique. GROUP "B": Obturated with GuttaFlow as per the manufacturer′s instruction. The teeth were split into two halves. Five randomly chosen longitudinal split teeth samples each from Group "A" and Group "B" was observed under scanning electron microscope to access the interface between obturating material and dentin at the level of 2 mm from the apex. Results: On statistical analysis the dentinal adaptation (μm) of Group A was observed with a mean of 0.52 and standard deviation 0.15, while the value of mean and standard deviation were noted 0.12 and 0.02 for Group B.The "t" value on comparison of Group A and Group B is 5.79 with "P " value of <0.001, which is highly significant.Conclusion: From result of the study it can be concluded Group B samples showed significantly superior seal when compared with Group A. Complete seal was not observed in any of Group A samples
