Abstract: ObjectiveTo evaluate the therapeutic efficiency and outcomes of vertical condensation of warm gutta-percha obturation using the four-handed technique.MethodsA split-tooth model constructed with lateral grooves and depressions was used to compare vertical condensation of warm gutta-percha obturation with and without the four-handed technique.Respectively 10 times of obturation were done in the four-handed group and the independent operation group.The operation time and defect replication quality were recorded.Evaluation of defect replication quality was on an ordinal scale 0 to 2 grade based on how much each defect was replicated.The results were statistically analyzed.ResultsThere were signiticant differences in treatment time between the four-handed group and theindependent operation group,as well as in treatment outcomes between two groups.ConclusionsUse of the four-handed technique can improve therapeutic efficiency and outcomes of vertical condensation of warm gutta-percha obturation.
