BLEEDING, BLEEDING, PCP, FMS
A comprehensive periodontal charting and intraoral examination were performed for all participants, and the periodontal status was examined by measurements of prior to and after the treatment in both groups and encompassed measurements of the following clinical periodontal parameters: clinical attachment loss (CAL), probing pocket depth (PPD), and bleeding on probing (BOP). Bleeding was determined using a periodontal probe (PCP UNC-15, Hu-Friedy, Chicago, IL) that flowed along the soft tissue wall of the entrance of the gum fissure and parallel to the long axis of the tooth in the facial/ lingual sites and directed towards the column in the interproximal sites; CAL was measured as the distance from a fixed reference point (cementoenamel junction, CEJ) to base of pocket, whereas PPD was measured as the distance between the free gingival margin and the clinically base of each periodontal pocket. Full mouth series (FMS) radiographs were obtained prior all treatments for all subjects to confirm alveolar bone level. Clinical parameters assessment was performed by measuring on six sites of teeth (mesial, median, and distal points at buccal and palatal aspects) [
