Use of photobiomodulation induced by polarized polychromatic non-coherent light in the management of adult chronic periodontitis.

The aim of the study was to evaluate the efficacy of a polarized, polychromatic, non-coherent light (Bioptron), in addition to full mouth scaling and root planing, in chronic periodontitis. Forty adult patients affected by chronic periodontitis were enrolled in the study and were randomly divided into two groups. The contro) group received only full mouth scaling and root planing (FMSRP), while in the test group, Bioptron light treatment was added to FMSRP. The Full Mouth Plaque Score (FMPS), Full Mouth Bleeding Score (FMBS), Gingival lndex (GI) and Probing Pockets Depth (PPD) were recorded in both groups at the first examination, after 1 month (Tl) and after 3 months (T2). Both groups showed a significant reduction of FMPS at Tl and T2 (p<0.05). Both groups showed a significant reduction of FMBS at Tl and T2 (p<0.05), but a higher improvement (p<0.05) was recorded in the study group at Tl. Study group GI was significantly reduced at T2 (p<0.05), differently from the contro( group (p>0.05). PPD showed a reduction in both groups with no statistically significant differences (p>0.05) between them. Polarized, polychromatic non-coherent light seems to be an effective additional therapy in the management of adult chronic periodontitis, reducing inflammatory clinical indexes.
