Aim: The aim of this study was to evaluate the effects of hyaluronan (HA) and chlorhexidine (CHX) gels as adjunct to scaling and root planing (SRP) in the treatment of chronic periodontitis.

Materials and Methods: 40 patients within the age group of 25 - 55 year participated in the study were randomly equally divided into four groups. Complete SRP and subgingival debridement were performed within all the patients. For control (Group IV) patients, SRP was the only treatment modality given; for group I, II and III patients, at least 10 teeth with 4 ‑ 8 mm probing pocket depth (PPD) were selected for subgingival application of Tetracycline fiber, HA gel and CHX gel, respectively. Clinical periodontal parameter such as gingival index, PPD, and clinical attachment level (CAL) were recorded at baseline and 3 months, whereas plaque index was recorded at baseline, 1 month, and 3 months.

Results: In all the four groups, a significant reduction in PPD and gain in CAL were observed between baseline and 3 months follow-up (P < 0.05); however, at 3 months, PPD was decreased more in group II. In group III pocket depth decreased less than group I but it is not significant. Group IV shows fewer changes in pocket depth than group I, II and group III, but the difference was non‑significant, and group IV (control) showed less changes in PPD and CAL than all experimental groups.
