ABSTRACT

Aims: The aim of this study is to compare the sealing ability of two root canal filling materials using a confocal microscope. Methods and Materials: Twenty human first premolars with intact roots, extracted for orthodontic purpose, were selected for the study. Root canal treatment was done in all the specimens and randomly divided into two groups (ten teeth in each group) and obturated with two different obturating materials (i.e. Themafill and Pro-Points). All the specimens were subjected to thermocycling and then stored in 100% humidity at 37ºC for 48 hours. Sealing ability was checked using stereomicroscope. Static analysis: Done by using tukey test and ANOVA. Result: The sealing penetration into dentinal tubules were observed more in Thermafil as compared to Pro-Point. Conclusion: Study concluded that Thermafill is the better material for obturation as it exhibits higher depth of sealing penetration than Pro-Points.
