FULLMOUTH ONE STAGE DISINFECTION VERSUS CONVETIONAL TWO STAGE SRP IN TREATMENT OF CHRONIC ADULT PERIODONTITIS – A PILOT STUDY

ABSTRACT Background: Conventional periodic scaling and root planing is carried out at two weeks interval to enable immune response to maintain a host-parasite equilibrium. This time lag will result in sub-gingival re-infection which may impair healing. A new treatment approach such as full-mouth disinfection completed in two consecutive days has been suggested to combat sub-gingival re-colonization. However, there exist some controversies in the two treatment modalities on clinical benefits. This study thus aimed to compare the effectiveness of full mouth one-stage disinfection and two stage scaling and root planing in chronic periodontitis. Materials and Methods: A total of 12 Patients were selected and randomly allocated to two groups with different treatment modalities. One group received full mouth one stage disinfection (FMD) and the other group received conventional scaling and root planing (SRP). Plaque index, bleeding index, probing pocket depth, serum WBC count and sub-gingival plaque bacterial load were evaluated for both the groups at baseline and at 21 days post-treatment. Results: The obtained data from all the parameters were analyzed using Student paired t test. Both treatment modalities lead to a significant improvement of clinical, hematological and microbiological parameters (p≤0.05). However comparison between the two groups showed no significant difference with high improvement in clinical parameter and high reduction in hematological and microbiological parameter in full mouth disinfection group. Conclusion: Both treatment modalities have a better clinical improvement with a limited benefit of SRP over FMD. KEYWORDS: Chronic periodontitis, Full mouth One stage Disinfection, SRP
