Twenty-six human mandibular incisor teeth with single root canals were instrumented and obturated with silver points and sealer. The efficacy of the initial seal was tested by immersion in radioiodine and counted for gamma radiation. Subsequently, the teeth were subjected to the vibration of an ultrasonic scaling device and reimmersed in the isotope so that the integrity of the apical seal could be reevaluated as a function of increased radioiodine uptake and thus increased gamma radiation. No significant difference was found after cavitroning. Author
