Abstract
Background: Periodontal diseases represent a group of localized microbial induced infections involving gingiva and supporting tissues of the teeth. The role of microorganisms in the etiology and progression of periodontitis is now well documented. Purpose: The current study was conducted to evaluate the effects of Diode laser versus PDT in periodontitis treatment as non-surgical method of treatment. Materials and methods:Thirty patients’ males and females suffering from gingival pockets with age range from 20 to 65 years old from faculty of oral and dental medicine out clinics and selected randomly and divided in 2 groups each group contains fifteen patients. group A received scaling and root planning in addition to 980 nm diode laser while group B group received scaling and root planning in addition to PDT. Results: There was statistically significant improvement in group A (F=114.697, P=0.000) and in group B (F=126.308, P=0.000). also, there was statistically significant difference between both groups (F=5.904, P=0.000) with most difference in Pocket depth only (F=21.122, P=0.000) with statistically significant differences in post treatment value (F= 2.333, P=0.000) and follow up at one (F=0.700, P=0.019) and six months (F=1.100, P=0.000). Conclusion:Both PDT and Diode therapy have significant effect in pocket depth, bacterial count and bleeding examination in periodontitis treatment, but PDT have Superior effect when pocket depth is the target.
