Utilidad del sistema waterpiñ power flosser en la eliminación de la burbuja apical durante el tratamiento endodóntico

Abstract

Objective: Asses the usefulness of the Waterpik Power Flosser system on the removal of the apical vapor lock using a radiographic evaluation with a contrast medium. Methods: This is an observational descriptive experimental study, 120 uniradicular permanent teeth with full root development were used. Coronal access was gained and teeth were prepared with the large instrument of the WaveOne system. They were also irrigated with sodium hypochlorite, the roots were sealed externally with nail polish. Teeth were divided randomly into 2 groups, 60 teeth each. Group A was activated with the Endoactivator system and group B with the Waterpik Power Flosser system. Each tooth was irrigated with a solution containing cesium chloride and an x—ray was taken to check the presence of the apical vapor lock. In each group the solution was activated for 15 seconds and a new x—ray was taken. In those teeth were the vapor lock didn't resolve, the irrigant was activated once more for 30 seconds or a minute. Results: the apical vapor lock was present in all the samples. The Endoactivator group dissolved the vapor lock more frequently (55%) than de waterpik power flosser group (48%) with no statistical difference. Conclusion: There isn't a difference between the two methods. The differences were the type of movement and the speed, factors that in turn didn't modify the results. Then this study confirms the usefulness of the waterpik power flosser in the removal of the apical vapor lock.
