CRITICAL THINKING QUESTIONS
1. A 38-year-old woman with severe periodontitis is in her tenth week of pregnancy. When the
dental professional tries to discuss oral hygiene and future appointments for scaling, the patient
becomes angry and says that she can live with bleeding gums and brown teeth from her smoking.
She also says that she is not interested in learning about hygiene because her teeth will
eventually fall out anyway. How could the dental professional convince this patient of the
importance of oral hygiene?
Discussion Guidelines: The dental professional should explain to the patient that periodontal disease
2. Roger Llamas is a 65-year-old man who has come into your office for a new patient
examination. His medical history indicates that he is taking medications for his type I diabetes
mellitus. On the basis of this information, do you think you might see any unusual conditions in
his oral tissues? If so, what and why?
Discussion Guidelines: Diabetics have a strong risk factor for periodontal disease. Individuals with
