Evaluation of Injectable Beta-tricalcium Phosphate Clinically in Treatment of Grade II Furcation Involvement

change in plaque index scores (PI) according to Silness and Löe.

Score 0 = no plaque in gingival area. Score 1= film of plaque adhering to the free gingival margin and the adjacent area of the tooth, plaque may only be recognized by running a probe across the tooth surface. Score 2= moderate accumulation of soft deposits within the gingival pocket and on the gingival margin and/ or adjacent tooth surface which can be seen by the naked eye. Score 3= abundant of soft matter within gingival pocket and/ or the gingival margin and adjacent tooth surface. The scores from the four surfaces of the tooth were added and divided by (four) to give plaque index for each tooth; the plaque index score for an individual was obtained by adding the indices of the teeth and dividing by the number of the teeth examined.

change in probing Pocket Depth(PPD)

The measurements were carried out to the defects selected using an 0.8 mm thick periodontal probe \* with William's calibration, which was marked from (1-10) mm, pocket depth of (1 mm) or less was recorded as (1mm),measurements exceeding (1mm) but less than (2mm) were recorded as (2mm) so that the probing pocket depth was measured to the nearest mm. Probing pocket depth refers to the distance from the gingival margin to the bottom of the pocket. Mesial and distal pockets were measured as well as the furcation from the buccal aspect as close as possible to the contact points, facial and lingual pockets were measured at midline of roots. Efforts were made to insert the probe parallel to the long axis of the roots. Light force was used during the introduction of the probe to the bottom of the pocket, third molars and teeth with enamel projections were excluded. (7)
