This study will utilize diode laser to determine its effects on improving periodontal parameters and inflammatory biomarkers, comparing with conventional treatment alone, and evaluate its effectiveness in improving periodontal disease's clinical parameters. Several studies have compared the effects of lasers and conventional periodontal treatment, comparing only its microbiological and clinical parameter levels and therapy to determine their effectiveness in key periodontal pathogens eradication and their effects on improving the clinical parameters of periodontal disease, in this study, salivary biomarkers will be collected and assessed to do a comparison between two treatment modalities. To the best of our knowledge, this is the first study to examine the effect of diode lasers on salivary biomarker levels.
