18. Mr. Larsen, a 52-year-old, has just moved into town and is new to this dental office. In completing initial oral assessments, Eric, the dental hygienist, noted straight line cuts on the anterior facial and lingual surfaces in the middle of the interdental gingiva. Mr. Larsen had periodontal probe depths from 1 to 3 mm, and his gingiva was stippled, pink, and firm, He also had moderate biofilm accumulations around his bridge in the lower left quadrant and minimal bleeding upon probing. Mr. Larsen reports brushing two or three times a day and flossing one to two times every day. When Eric asked him to demonstrate brushing and flossing, he noticed that Mr. Larsen used a 24-inch piece of floss and snapped it between the contact areas. He also noticed Mr. Larsen used a scrubbing technique when brushing. When Eric commented on his brushing and flossing technique, Mr. Larsen stated that he has always done it this way an
