CONVENTIONAL VERSUS LASER-ASSISTED THERAPY WITH AGGRESSIVE PERIODONTITIS

Abstract

Aim of the study To evaluate tissue response in aggressive periodontitis (AgP) after conventional and conventional supplemented with laser-assisted therapy. Material and methods This study included 50 subjects with AgP, aged 10 -24 year, which were divided into two subgroups. Firs subgroup 25 subjects treated only with conventional therapy (CP) and second subgroup of 25 subjects which were treated with laser assisted therapy (CP-LA). Low-level diode laser (630-670 nm, 1.875 J/cm) was applied, each sextant for 4 minutes, Scorpion C- 405 7A (Optica Laser, Sofia, Bulgaria). The control group consisted of 20 individuals, aged 13-24 years, without signs of periodontal disease. Gingival tissue biopsies were obtained from the controls and from the study group before and after conventional and with laser assisted treatment. Tissue specimens were embedded in paraffin and cryostat procedures were performed. Results Gingival tissue specimens from study group compared to controls showed dense infiltrate. Subject with AgP revealed heterogeneous inflammatory infiltrate with dense and less dense areas. Almost equal values from quantitative measurements of connective tissue inflammatory infiltrate were obtained. Mean values for study group before treatment were 39,18± 14,02 . For the first subgroup mean values ranged 35,92± 14,02, and mean values for the second subgroup were 35.01 ± 13.25. Qualitative analysis in study group after conventional without and with lasser assistance revealed insignificant values of mononuclear and plasma cells and Russell bodies. Conclusions Laser application did not induce quantitaive nor qualitative changes in the gingival tissue inflammatory infiltrate in study group. On the basis of our findings we suggest that low level laser assisted therapy does not proof to be efficient in the treatment of aggressive periodontitis.
