Primary objective of root canal therapy is to eradicate microorganisms followed by perfect seal obtained by obturation of the root canal. The purpose of doing this study was to find out quality of apical seal of root canal obturated by cold lateral technique. For obturation, epoxy resin based sealer was used and tested at various interval of time period of at 1 week,4 weeks and 8 weeks.
We selected 180 permanent extracted teeth with single root. x.smart protaper were used for canal instrumentation, obturation was done by lateral cold condensation. Samples were stored for 24 hours in an incubator .Finally, prepared tooth sample were divided into two major group. Control gp [n=30] and experimental group[n=150]. We sub divided the experimental group into further three sub group, containing fifty teeth each, representing the immersion period of 1 week, 4weeks and 8 weeks in methylene blue 5% dye, at a constant temperature of 37º. After storage the samples were sectioned and observed under stereomicroscope. Linear dye leakage was evaluated in millimeters. Statistical analyses was done by using SPSS of Windows V. 16.0 .Descriptive statistics were shown as Mean±SD in millimeters (mm).One Way ANOVA were used to evaluate the mean dye leakage value differences. The significance level was set at 0.05.
Group A exhibited minimum leakage (2.53mm,SD ±0.87) followed by, Group B (2.69mm,SD±1.01) and Group C (2.77mm, SD±1.02) respectively. The difference amongst all three groups was statistically insignificant. (p=0.468). However 50% teeth in Group C showed grade 3 dye penetration with comparison to 40% and 30% in Group A and Group B.
Every samples leakage.. A gradual increase in mean leakage value was observed as the storage time increases. The differences amongst the groups remain insignificant (p=0.468)
