Nancy, a 67-year-old woman, comes into the dental office for a routine prophylaxis and examination. She has not been seen in the
office for just over 1 year and states that she has had her grandchildren staying with her, which has made it hard for her to make an appointment. Nancy has 12 teeth present in her mouth and states that she has not been wearing her partials because they do not fit very well. The hygienist notes that she has angular cheilosis and heavy biofilm accumulation. Upon further questioning, Nancy reveals that it is hard for her to chew without her partials so she has been eating a soft diet. The dental hygienist decides to complete a dietary assessment with Nancy. When she returns the 3-day record it is evident that Nancy is primarily eating breads, cakes, soups, ice cream, and yogurt since she has trouble chewing. Nancy has also indicated drinking five cans of soda daily. Reference: Ref 35-1 Open and read the attached case to answer the following question. Nancy states that she drinks soda all day in order to keep up with her grandchildren; this is a problem because: Select one: a. the teeth are exposed to a cariogenic liquid for a long period of time. b. the pH level is very high in the oral cavity when drinking soda. c. it may cause xerostomia. d. she may gain weight.
