She takes Xanax (alprazolam) for anxiety and migraines; Atenolol (tenormin) for hypertension; Glucotrol (glipizide) for diabetes and an over-the-counter antihistamine product for seasonal allergy relief. She occasionally experiences dry mouth; she reports brushing twice per day, flossing occasionally, and using Parodontax toothpaste without fluoride. In addition, she states that her gums bleed every time she brushes and flosses her teeth. Ms. Ivory has moderate levels of cervical plaque biofilm. She reports using a soft toothbrush but cannot remember the brand name. She also experiences sensitivity to cold, sweets, and pressure in the mandibular right posterior quadrant. She is missing teeth #1, #3, #14, #16, #17, and #32. A class I furcation involvement is present on the buccal surface of tooth #19, and generalized 2- to 3-mm recession throughout her mouth, with class II embrasure spaces. Radiographs show moderate horizontal bone loss and moderate subgingival and supragingival calculus, especially in the interproximal areas.
