ABSTRACT

Aims: The aim of this study is to evaluate the sealing ability of three root canal filling materials using a confocal microscope. Methods and Materials: Thirty 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 three groups (ten teeth in each group) and obturated with three different obturating materials (i.e. Thermafil, Pro-Points and Gutta Flow). All the specimens were subjected to thermocycling and then stored in 100% humidity at 37ºC for 48 hours. Sealing ability was checked using Confocal Microscope Thermafil. 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 and Gutta Flow. Conclusion: Study concluded that Thermafil is the better material for obturation as it exhibits higher depth of sealing penetration than Pro-Points and Gutta Flow.
