| Abstract | ||
| One hundred Thirty two canals from 66 mesial roots of extracted human mandibular molars were instrumented with Protaper and K-file crown-down technique and divided into two groups. The group I was obturated with Thermafil technique and group II was obturated with lateral condensation technique. Topseal sealer was used in both groups. Apical extrusion, apical microleakage, time for instrumentation and time for obturation were recorded in each sub group. Six molars were used as control teeth. All specimens were stored in 100% humidity for 1 week, coated with nail polish, except for the apical 2mm, and were suspended in methylene blue dye for 72h. Linear dye leakage was statistically different (ANOVA) test, while apical extrusion between techniques was not statistically different (Chi-square test). | ||
