Case GV: Ginger Vitis, RDH’s patient is a 58 year old African-American male in for his three-month periodontal maintenance recall appointment. He has high blood pressure that is controlled with Toprol-XL ® (metoprolol) and recently had a cardiac pacemaker placed. Ginger notices a couple of lesions on the left buccal mucosa where the patient recalls he bit his cheek. Ginger notes several amalgam restorations, and a 3 unit bridge on the UL. The patient has generalized recession and pockets ranging from 2 to 6 mm. He has a couple of areas of graininess and one small spicule of subgingival calculus in the upper anterior with a thin band of calculus visible supragingivally in the lower anterior lingual area. His oral hygiene is fair, with a thin line of biofilm accumulated along the gingival margin of most all posterior teeth and a little heavier on some anterior teeth. He is very agitated because he was on time for his appointment but was not seated until 15 minutes after he arrived.Case GV: Ginger wants to use an ultrasonic scaler to remove the supragingival deposit. What is the primary criteria must she consider when making that decision?
