A new method for treating weeping canals: clinical and histopathologic study.

Abstract

In this study the effect of Nd:YAG laser on the apical oozing of the weeping canals was evaluated both clinically and histopathologically. It was noticed that application of the laser beam at energy 15 pps/1.50 w for 2-2.5 minutes to the apical position of these canals resulted in complete dryness of the canals in 82-23% of the cases. On the other hand most of the lased teeth become relatively asymptomatic after laser application. Histopathologic examination of the periapical lesion related to weeping canals showed marked improvement in the inflammatory condition. Sixty percent of lased cases showed grade 1 inflammation where 70% cases showed grade 3 inflammation in unlased cases.
