Abstract

The vertical compaction technique is an improvement to increase the fit in root canal fillings. Currently, on the market, the EQ-EV heat compactor is being introduced by the manufacturer and being used by many clinics. Objective: Evaluation of the effectiveness of sealing the root canals with the EQ - EV heat compactor Methods: A Non-controlled case study was conducted. Results and conclusion: Through surveying the results of filling the canals of 30 teeth with the EQ-EV heat compactor, it shows that: there is the correlation between the volume of fillings and canals on X-ray film: 90% full - filling; excess filling rate: 6.7%; missing fillings: 3.3%. The correlation between cementum and tooth apex shows that the rate of cement reflux in the apical region: is 10%; missing is 3.3%. The correlation between GP and apex shows that the ratio of GP is moderate to the apex of 90%; rate over apex 3.3%; Missing in the apical 1/3 is 6.7%. The homogeneity of the filling material by compaction is high 93.3%. The adaptation of the root canal surface to the first third of the neck: 100%; middle third: 96.7%; apical 1/3 segment 96.7%.
