Background: Periodontal disease is an inflammatory condition affecting the tissues that support teeth. It is brought on by a variety of microorganisms and causes the alveolar bone and periodontal ligament to gradually deteriorate, either via recession or pocket development. The present study was conducted to evaluate role of tetracycline fibres in chronic periodontitis patients. Materials & Methods: 60 patients of chronic periodontitis of both genderswere divided into 2 groups pf 30 each. Group I underwent scaling and root planning and group II patients underwent scaling and root planning followed bylocal application of tetracycline gel. Parameters such as plaque index, gingival index and probing pocket depth at 1 month, 3 months and 6 months. Results: Group I had 12 males and 18 females and group II had 17 males and 13 females. The mean probing pocket depth at 1 month was 1.54 and 1.25, at 3 months was 1.50 and 1.42 and at 6 months was 1.44 and 1.28 in group I and II respectively. The mean plaque index 1 month was 0.57 and 0.45, at 3 months was 0.75 and 0.57 and at 6 months was 0.79 and 0.63 in group I and II respectively. The mean gingival index was 0.45 and 0.33 at 1 month, 0.57 and 0.45 at 3 months and 0.73 and 0.61 at 6 months in group I and II respectively. The difference was significant (P< 0.05). Conclusion: When tetracycline was used as an adjuvant to SRP, individuals with periodontitis show improved clinical parameters compared to SRP alone.
