The duration of the treatment depends mainly upon the length of the track and also upon the root. Diseases like diabetes, Crohn’s, tuberculosis, carcinoma of the rectum etc. interfere with the normal healing process. Roughly speaking, the unit cutting rate of the Ksharasutra is about 0 to 1 cm per week. Hence if the track is 6cm long, it could take 10 weeks to heal.
