The Adjunctive Use of Antimicrobial Photodynamic Therapy, Light-emitting-diode Photobiomodulation, and Ozone Therapy in Regenerative Treatment of Stage III Grade C Periodontitis
In Brief
A clinical study evaluating Control group, Antimicrobial photodynamic therapy (aPDT) group, and 2 other interventions for Periodontitis and 4 related conditions. Completed, enrolled 48 participants across 1 site.
Detailed Summary
Anti-infective procedures play a very important role in the success of regenerative surgical treatment of aggressive periodontitis, Grade C periodontitis, which shows the newly named molar-incisor pattern according to the 2017 World Workshop Classification of Periodontal Diseases. In the present study, it was aimed to analyze the effects of photodynamic, photobiomodulation, and ozone therapy applications on periodontal healing, both clinically and immunologically, in addition to the surgical regenerative treatment of aggressive periodontitis. Forty adult individuals diagnosed with aggressive periodontitis who applied to Gazi University Faculty of Dentistry Department of Periodontology for the treatment of periodontal disease were included in the study. In addition to the regenerative surgical treatment using cortico-cancellous particle allograft and a resorbable collagen membrane in randomly determined areas with multiple intraosseous defects, topical ozone, antimicrobial photodynamic, and light-emitting diode (LED) photobiomodulation treatments were applied. Periodontal clinical parameters \[plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing pocket depths (PPD), clinical attachment level (CAL), gingival recession (GR), and width of keratinized gingival (WKG)\] were examined and patient-centered postoperative evaluations, and early wound healing index (EHI) assessments were performed for 2 weeks after the operation. In addition, gingival crevicular fluid (GCF) samples from patients to determine the total amount and concentration of vascular endothelial growth factor (VEGF), interleukin -6 (IL-6), Runt-related transcription factor 2 (RunX2), NEL-like 1 (Nell-1), Osterix and samples were quantified by Quantitative Real-Time PCR. The repeated measures ANOVA model was used for the analysis of variables in which both group and time measurements were taken.

Interventions
Following local anesthesia, a full-thickness (muco-periosteal) access flap was elevated, granulation tissue was removed and direct instrumentation of the affected root surfaces was performed under the saline irrigation. Intrabony defects were filled with granules of allograft bone material and covered with a native porcine pericardial collagen membrane. The flaps were repositioned and sutured without any tension in order to achieve primary closure of the inter-dental area using a 5-0 mono-filament non-resorbable PTEF suturing material. On the 1st, 3rd, and 7th postoperative days, the sites in the control group received only saline irrigation for 1 min.

On the 1st, 3rd, and 7th postoperative days, aPDT group received additional application of a diode laser with a wavelength of 810 nm and a power rating of 200 mW (continuous mode). Indocyanine-green (ICG) as a photosensitizer at a concentration of 1 mg/ml was applied at the surgical site on both the buccal and the lingual sides of the flaps. Irradiation was performed in non-contact mode in a constant distance of 1 mm during 30 s per site

On the 1st, 3rd, and 7th postoperative days, irradiation was carried out with a LED device with a wavelength of 626 nm in the near-infrared region at a dose of 20 mw/cm2 for 20 min with a total energy of 222 J
