METHOD OF TREATING RADICULAR CYSTS Russian patent published in 2015 - IPC A61N5/67 A61K31/5415 A61P1/02 

FIELD: medicine.

SUBSTANCE: carious cavity is prepared. Then it is treated instrumentally and antiseptically. A hole of an apical canal of a causative tooth is expanded. Methylene blue is introduced into the cyst through a root canal at a depth of 7-10 min. The cyst envelope is exposed to a laser light generated by a diode laser through the root canal for 30-60 s by means of a needle light guide. The exposure is continued from the vestibular or oral surface for 60.0-120.0 s by means of a plate light guide of intensity 0.5-1 W, wave length 625-630 nm in a pulse mode. Before the root canals of the causative tooth is hermetically sealed, Collap-An gel with metrogil 1.0-1.5 ml is introduced into the cyst.

EFFECT: method enables provides increasing clinical effectiveness, avoiding the complications by removing the cyst envelope completely that enables restoring the bone defect structure completely.
