A COMPARATIVE STEREOMICROSCOPIC EVALUATION OF BIOACTIVITY OF DIFFERENT BIOMIMETIC ROOT END FILLING MATERIALS - AN IN VITRO STUDY

Abstract

The interaction between MTA and phosphate-containing fluids results in bioactivity of MTA. Recently, new bio ceramic materials have been introduced as an alternative to MTA. Neo MTA plus and biodentine.

Aim: Hence the aim of the study is to find out and compare the bioactivity of Neo MTA Plus, Pro root MTA white, Biodentine & Glass ionomer cement as root end filling materials using 1% methylene blue as tracer.

Objectives: To comparatively evaluate 1: The sealing ability of different root end materials;2: The change in sealing ability of different root end filling materials with time; 3: To evaluate seal of bioactive materials and glass ionomer cement.

Methodology: Freshly extracted, permanent, single rooted human maxillary central incisor teeth were collected. Samples were, randomly divided into four groups, consisting of 20 samples each, filling Group I with GIC, Group II with pro root MTA, Group III with neo MTA plus and Group IV with biodentine. The evaluation depth dye penetration was done with the help of Stereomicroscope at 2x magnification at 7days and 1 month period intervals.

Result: All the four materials exhibited penetration.

Conclusion: Neo MTA plus and biodentine should be the preferred choice for root end filling.
