A study was conducted to compare the effects of chlorhexidine mouthrinse and chlorhexidine acetate powder with periodontal pack during 4 weeks following periodontal surgery. Twelve patients were treated with Modified Widman flap procedures and devided into three groups of four patients each; control group, chlorhexidine mouthrinse group, chlorhexidine acetate powder group. Each group wasn't significant difference in clinical and microbiologic parameters at preoperation. Examination regarding plaque index, gingival index, pocket depth, change of gingival color postsurgically, pain index were performed by each methods and observed bacteria in gingiva by phase contrast microscope. Evaluations were made at 7, 14 and 28 days postsurgically. The results were as follows: l. In comparison of results revealed no significant differences in Plaque Index, Gingival Index, pocket depth and change of gingival color postsurgically. 2. The pocket depth of three experimental groups were significant reduced at 4 weeks. 3. Chlorhexidine mouthrinse group and chlorhexidine acetate powder group with periodontal pack were significant differences in pain index at 3, 4 days postsurgically. 4. Cocci and Non-motile rods were increased at 1, 2 weeks. But, motile rod and spirochete were increased at 4 weeks.

This paper proposes the reduction for the test patterns of AAL(Subscripted D -Algorithm) in a combinationl logic circuit with non- feed back. The propese algorithm os called MSSA(Multiple path & Sinfle path Sensitization Algorithm) that defined the multiple path segments and the single path segments. As a results, the MSSA generates the minimal length test patterns and recuces the test patterns less than AALG.
