Comparative evaluation of ozone therapy as an adjunct to scaling and root Planing with scaling and root planing alone in cases of chronic Periodontitis- a clinical and microbiological study

caries, hypersensitivity, but studies regarding periodontal disease are very few. Periodontal pathogen
which reside in the sub gingival area needs alternative treatment along with conventional treatment to
inhibit their growth and prevent further progression of periodontal disease. One possible means is to
change the subgingival environment which is shown to be highly anaerobic with a prevailing low
oxygen tension. Ozone has a potent antimicrobial power along with its capacity to stimulate
circulatory system and modulate the immune response and this makes it a therapeutic agent of choice.
This study was therefore planned to evaluate the efficacy of aqueous ozone as an adjunct to Scaling
and Root Planing in subjects with Chronic Periodontitis. Material and Method: A total of 20
subjects of Chronic Periodontitis were enrolled for the study. 40 Sites with probing depth of 6-7mm
from two different quadrants of same arch were selected for the study. Selected sites were randomly
divided into 20Control sites with Scaling and Root Planing and 20Experimental sites Scaling and
Root Planing with Ozone irrigation. Clinical parameters such as Gingival bleeding Index, probing
depth, Relative attachment level were assessed at baseline and 3rd week. Total Microbial count were
assessed at baseline and next day. The results were subjected to statistical analysis. Results: In the
experimental group statistically significant reduction was seen in Gingival bleeding Index, Probing
depth and Total microbial count and there was statistically significant gain in Mean Relative
attachment level as compared to control group.
Conclusion: Ozone application can be used effectively to treat periodontal disease non-surgically in
professional practice.
