Abstract

The major cause of periodontal disease is microorganism in the dental plaque. Gingival sulcular fluid, which is exudate released from the tissue near crevicular epithelium is related with inflammation. The purpose of this study was to evaluate the argon laser efficiency between the clinical index and onset of collagenase of gingival sulcular fluid. Material divided 16 patients into 4 groups. The first control was without treatmemt. The second was with just treatment of argon laser, The third was treated by scaling and root planning and the fourth was treated with both scailing and root planning and argon laser. The level of periocheck test, the index of bleeding, and the depth of periodontal pocket were evaluated from for 128 teeth of 64 anterior teeth and 64 posterior teeth. The results were as follows; 1. In the score of periocheck test, root planing group(group 3) was significantly reduced more than the group without treatment(group 1) and the argon laser treatment(group 2) for results of 3 days and 7 days. But root planing plus argon laser treatment(group 4) in the 7days after experiment, was significantly reduced than no treatment(group 1) and root planing treatment(group 3)(P < 0.05), in the 3 days after experiment, was significantly reduced than root planing(group3)(P < 0.05). The score of periocheck test to the root planning group(group 3) were significantly reduced between days1, day3 and day7(P < 0.05). Root planning plus argon laser group(group 4) were significantly reduced to 1 or 7days and 3 or 7days(P < 0.05). The argon laser group(group 2) didn't show any changes. 2. In the case of sulcus bleeding index, the root planning group(group 3) and root planning plus argon laser group(group 4) were reduced more than without treatment group(group 1)(P < 0.05) and sulcus bleeding index in the root planning group(group 3) were reduced more than the argon laser group(group 2)(P < 0.05). 3. There wasn't any changes of pocket depth between the control and the experiment group as with experiment periods also.
