NS (P>0.05). NS – Not significant; n – Number of patients; t-value – Size of the difference; P – Probability value; SD – Standard deviation; PI – Plaque index; PBI - Papillary bleeding index; PD – Probing depth; CAL – Clinical attachment level; ROM – Reactive oxygen metabolite; GCF – Gingival crevicular fluid; CARR U – Carratelli units; SEM Standard error of the mean
