Evaluation and comparison of the effect of ozone therapy and photodynamic therapy in non-surgical management of chronic periodontitis

Abstract

Among the non-invasive therapies to achieve better plaque control, photodynamic therapy (PDT) and ozonated water therapy (OT) are being widely recognized as two reliable techniques. PDT using low-level laser irradiation is known to selectively target the periodontal pathogens without potentially damaging the host tissues. Ozone therapy on the other hand has antimicrobial, analgesic, immune-stimulating, immune-modulatory, and anti-inflammatory properties, it also oxygenates tissues and enhances their regeneration potential. It has been proven to strongly inhibit the formation of dental plaque. Objective: To evaluate and compare the effect of ozonated oil therapy (OT) and photodynamic therapy (PDT) in nonsurgical management of chronic periodontitis. Methodology: Twelve patients diagnosed with chronic generalized periodontitis were subjected to the study. Following the assessment of gingival index, periodontal pocket depth, and clinical attachment loss, all patients underwent full-mouth scaling and root planing. The study had a split-mouth design, one quadrant of each patient was subjected to ozonated oil therapy with a 22-gauge needle and the contralateral quadrant was treated with PDT, using indocyanine green dye. Patients were recalled after one month and the clinical parameters were recorded again. Results: A statistically significant reduction was observed in all the clinical parameters in both the study groups at 1 month follow up period. Conclusion: Results showed that there was equal improvement in the clinical outcomes in both the groups. Key words: Chronic periodontitis, Ozone therapy, Photodynamic therapy
