Abstract
Laser ablation is used in curettage to treat periodontal disease. After an initial step of ablating afflicted tissues, an anti-microbial rinse is applied. A flexible fiber optic guide is the preferred means of directing radiant energy to the afflicted tissues. Sulcular disinfection may also be achieved by similar associated processes. Various anti-microbial agents and laser sources are disclosed.
Claims12
A method of treating periodontal disease comprising:
- measuring a pocket depth in a periodontal pocket;
- pre-flushing the periodontal pocket with a fluid containing an antimicrobial agent;
- obtaining an apparatus capable of generating radiant energy, the apparatus having a fiber optic cable surrounded by a cladding layer;
- removing a length of cladding layer from an end of the fiber optic cable approximately equal to the pocket depth creating a bare fiber optic portion;
- inserting the bare fiber optic portion into the periodontal pocket;
- directly applying radiant energy to an area of infected tissue in a periodontal pocket exhibiting periodontitis sufficient to ablate the infected tissue;
- and
- post-flushing the periodontal pocket with the fluid containing an antimicrobial agent.
