A Novel Treatment AId to Orthodontic Gingival Enlargement With Photodynamic Therapy Compared to Chlorhexidine and Diode Laser as Adjunct to Scaling and Root Planing - A Split Mouth Study

Background And Objectives: Inammation or enlargement of gingival tissue is one of the most common problems associated with xed orthodontic mechanotherapy. It increases bacterial retention and alters the equilibrium of oral microora. There are various treatment modalities for orthodontically induced gingival inammation/enlargement. Scaling and Root planing (SRP), antiseptic agents such as Chlorhexidine (CHX), LASER therapy and Photodynamic therapy (PDT) may help to reduce this. The objective of this study was to assess and compare the outcome of all the four treatment modalities. Twenty patients Methods: undergoing orthodontic treatment with gingival inammation/enlargement were selected and the quadrants were divided randomly into four groups; SRP alone, SRP + 0.2% Chlorhexidine, SRP + DIODE LASER and SRP + PDT. Treatment was done once every month for 6 months. Periodontal parameters were assessed at baseline, third and six months. Plaque-index, Gingival-index, Bleeding-on-probing, Probingpocket-depth and Gingival-overgrowth-index were assessed at every monthly visit. Statistically signic Results: ant improvements were found in six months follow-up period for all the variables compared with baseline. The improvement in clinical parameters were signicantly greater in Group 4 compared to Groups 1, 2 and 3. Within the Conclusion: limits of study, it can be concluded that combination of multiple applications of 0.2% Chlorhexidine subgingival irrigation, LASER Therapy and PDT provide additional benet to SRP in terms of clinical parameters. Even though all treatment modalities showed good results, Photodynamic Therapy showed better improvement in all the clinical parameters followed by low-level laser therapy and 0.2% Chlorhexidine subgingival irrigation.
