[Clinical evaluation of electronic dental analgesia during ultrasonic scaling].
OBJECTIVE
To evaluate the effect of electronic dental analgesia (EDA) device--Team Up Duo during ultrasonic scaling.


METHODS
The clinical trial was conducted as a randomized double-blind split-mouth design. Eighty-one patients requiring ultrasonic scaling were selected as subjects. Patients received treatment using the EDA device either in an active or an inactive state in paired quadrants. The patients scored their pain/discomfort levels with visual analog scale (VAS) after each procedure and filled a questionnaire.


RESULTS
In questionnaire, 79.0% patients felt EDA could relieve pain/discomfort during ultrasonic scaling. But the double-blind test showed that Team Up Duo was effective in 46.9% patients overall. The effective rate was 55.1% and 34.4% in groups with or without attachment loss, respectively. In CP group, the success rate of EDA was not statistically significantly different between the groups according to sex, age or site.


CONCLUSIONS
When using Team Up Duo during ultrasonic scaling, most patients subjectively believed that it was effective for controlling pain. In fact, this EDA device was effective in partial patients.
