The advancing technical sciences in recent years have made the application of controlled low temperatures an easy option in many branches of dentistry. From the past few years the uses of cryoablation have been proliferating immensely; nevertheless, many of the applications further require experimental evidence.

Cryotherapy is the local application of low temperatures resulting in necrosis of the tissues. The aim of the study includes application of liquid nitrogen using cryogun, locally to ablade oro–mucosal lesions. This process of Cryotherapy not only provided a blood free operative site but it also hastened the healing process with no scar formation and post–operative infection.

This controlled destruction by freezing is very economical, easy, and safe treatment which is being widely practiced in medicine.
