Abstract

Periodontitis represents a major problem for patients, since it is not possible to eliminate the bacteria that are responsible for this pathology with a pharmacological treatment. The present study included forty-four patients with periodontitis, who had undergone disinfection via photodynamic therapy (PDT) using a laser source having a 635 nm wavelength associated with a photoactivable substance (methylene blue). Clinical assessment of plaque index (PI), bleeding on probing (BOP), probing depth (PD), calculus index (CI), gingival recession (REC) and clinical attachment level (CAL) were recorded at base line, 1 month (4 weeks) after treatment and again 3 months (12 weeks) after treatment, while site radiography (RX) and microbiological test (MT) were recorded at base line and 3 months (12 weeks) after treatment. The outcomes show a good efficacy of the PDT in the elimination of the periodontal pathogenic microflora and in the improvement of the clinical parameters considered: from the base line to the final check after 12 weeks it has been observed a reduction in REC of about 16.9%, a reduction of CAL of about 17.85%, a reduction of the BoP of about 93.3%, a reduction of the PD of about 17%, a reduction of the CI of about 66.3%, a reduction of PI of about 44%, and microbiologically a reduction of the total amount of bacteria with proven parodontopathic properties (red complex bacteria) of about 58.74%. Within the limits of the present study, PDT can be reasonably considered as a good carrier that leads to significant improvements in the parameters (clinical and microbiological) considered.
