Comparative evaluation of sealing ability of glass ionomer-resin continuum as root-end filling materials: An in vitro study.

Chohan H, Dewan H, Annapoorna BM, Manjunath MK - J Int Soc Prev Community Dent (2015 Nov-Dec)

Bottom Line: The teeth were immersed in methylene blue for 48 h, split longitudinally, and dye penetration was measured.A highly significant difference existed in the mean dye penetration of Group I (conventional glass ionomer) and the other groups (resin-modified glass ionomer, polyacid-modified composite, and composite resin).There was no statistically significant difference among the three groups. (1) Significant difference was found in the dye penetration values of conventional glass ionomer cement and other groups. (2) No statistically significant difference was found in the dye penetration values of groups II, III, and IV.

ABSTRACT

Background and objectives: Root-end filling is a prudent procedure aimed at sealing the root canal to prevent penetration of tissue fluids into the root canals. An ideal root-end filling material should produce a complete apical seal. Therefore, the aim of this study is to compare the leakage behavior of four different root-end filling materials.

Materials and methods: Sixty-eight maxillary central incisors were obturated with laterally condensed gutta-percha and AH plus sealer. The roots were resected at the level of 3 mm perpendicular to the long axis of the tooth. Root-end cavities were prepared with straight fissure stainless steel bur. The teeth were then divided into four experimental and two control groups, and cavities restored as per the groupings. The teeth were immersed in methylene blue for 48 h, split longitudinally, and dye penetration was measured.

Results: A highly significant difference existed in the mean dye penetration of Group I (conventional glass ionomer) and the other groups (resin-modified glass ionomer, polyacid-modified composite, and composite resin). There was no statistically significant difference among the three groups.

Conclusions: (1) Significant difference was found in the dye penetration values of conventional glass ionomer cement and other groups. (2) No statistically significant difference was found in the dye penetration values of groups II, III, and IV.
