The use of ozone therapy as an adjuvant in the treatment of periodontitis in patients attending the Dr René Puig Bentz Clinic of the Universidad Nacional Pedro Henríquez Ureña.

Periodontitis is a chronic inflammatory disease that affects the supporting tissues of the teeth and can lead to tooth loss if not properly treated. Conventional non-surgical treatment is often complemented by the use of antimicrobial mouthwashes such as chlorhexidine. However, its adverse effects and limitations have driven the search for alternatives. This study aimed to evaluate the effectiveness of ozonated water as a mouthwash compared to chlorhexidine in the treatment of periodontitis.

The hypothesis proposed is that the use of ozonated water as a mouthwash, in combination with conventional periodontal treatment, provides clinical results equal to or better than those obtained with chlorhexidine in patients with periodontitis.
The study was conducted on a sample of 50 patients diagnosed with periodontitis, randomly divided into two groups: an experimental group, which used ozonated water as a mouthwash, and a control group, which used 0.12% chlorhexidine. Patients were administered the mouthwash during consultations, both before and after each procedure. The evaluation of clinical parameters included the plaque index, measured using the O’Leary Plaque Index; periodontal pocket depth, determined with the help of periodontal probes; and gingival inflammation, assessed by clinical inspection based on the criteria established by the UNPHU School of Dentistry.
The data showed that the control group experienced a greater reduction in gingival inflammation compared to the experimental group. Regarding the plaque index, the percentage of patients who achieved an optimal level was higher in the control group than in the experimental group. On the other hand, in terms of periodontal pocket depth reduction, the experimental group obtained better results.
These findings suggest that ozonated water can be considered an alternative to chlorhexidine due to its biocompatibility and absence of adverse effects. Its use could contribute to the improvement of clinical parameters; however, its effectiveness still appears to be lower than that of chlorhexidine.
