INFLUENCE OF A SINGLE APPLICATION OF SUBGINGIVAL CHLORHEXIDINE GEL ORTETRACYCLINE PASTE ON THE CLINICAL-PARAMETERS OF ADULT PERIODONTITIS PATIENTS

The clinical effects of subgingivally placed 1% chlorhexidine gel (w/w ) and 40% tetracycline (w/w) paste in periodontal pockets of 22 adult periodontitis patients were studied. The 2 agents were applied followi ng scaling and root planing in pockets exceeding 4 mm. The patients we re randomly divided into 3 groups: (a) scaling and root planing (SCRP) only, the control group; (b) corsodyl gel + SCRP; (c) Tetracycline pa ste + SCRP. Gel or paste were gently applied using a syringe with a bl unt needle until the selected pocket was overfilled. Evaluations were made of clinical parameters including the plaque index (PI), gingival index (GI), bleeding index (GI-S), probing pocket depths, probing atta chment levels and position of the gingival margin. The results suggest ed that all the treatment modalities were effective in producing stati stically significant improvements in clinical parameters. It was concl uded that the conventional treatment modalities were essential in the treatment of periodontal diseases, but in view of the structure of the periodontal pocket and adjacent complex root surface, subgingival dru g application in certain cases, might also provide adjunctive improvem ent.
