39. STUDY ON CLINICAL AND PARACLINICAL AND EVALUATION OF PERIODONTITIS TREATMENT OUTCOME USING FLAP SURGERY COMBINED WITH 940NM DIODE LASER AT ODONTO - MAXILLO FACIAL HOSPITAL IN 2023
Main Article Content
Abstract
Background: In the treatment of periodontitis, scaling and root planing may not prevent the invasion of pathogenic bacteria and can result in the loss of dental tissue with repeated treatments. Laser therapy is currently regarded as a supportive treatment method, offering bactericidal effects, promoting new attachment, stimulating tissue regeneration, and reducing side effects post-treatment.
Objectives: 1) To describe the clinical and paraclinical characteristics of patients undergoing periodontitis treatment through flap surgery - with and without the support of a 940 nm diode laser—in the treatment of deep periodontal pockets. 2) To evaluate the treatment outcomes of the two surgical methods (flap surgery with and without the support of 940 nm diode laser) at the initial time and after 3 months of surgery.
Materials and methods: This randomized controlled clinical trial and split-mouth study involved 88 teeth with stage III and IV periodontitis, equally divided into two treatment groups: flap surgery with and without the support of a 940 nm diode laser.
Results: 65.9% of teeth were in stage 3, and 34.1% were in stage 4. 47.7% of teeth exhibited horizontal bone loss, 63.6% had vertical bone loss, 63.6% had interproximal bone loss, 22.7% had cervical bone loss, and 25.0% had apical bone loss. The highest proportion of bone loss/age ratio >1 was observed in 63.6% of cases. The wound healing index of the OFD group increased significantly on day 7 compared to immediately after surgery and on day 3. The wound healing index on days 3 and 7 post-treatment of the LA-OFD group was significantly lower compared to the OFD group. The visual analog scale (VAS) pain scores for both the OFD and LA-OFD treatment groups significantly decreased after 7 days of treatment. The VAS pain score on day 7 of the LA-OFD treatment group was significantly lower than that of the OFD treatment group. After 3 months of treatment, there were no statistically significant differences between the two treatment groups in all clinical indices (PI, mSBI, PPD, CAL, TM, GR). Post-treatment, the PI, mSBI, PPD, CAL, TM, GR indices in both the OFD and LA-OFD treatment groups decreased compared to pre-treatment values.
Conclusions: Combining 940 nm diode laser with flap surgery for the treatment of deep periodontal pockets yields superior results compared to conventional flap surgery without the use of a laser.
