Introduction to Dental Medicine
Week 4 quiz
Which type of or location of caries is often associated with head and neck radiation (where on the tooth or how do these caries occur)?
Head and neck radiation has a tendency to cause extreme dry mouth in patients. This leads to general demineralization as patients lose the protective effects of saliva. Because the root surface is less highly calcified than other structures, it is usually the first to decay, often in a rapid manner.
Which of the following may contribute specifically to the chronic form of periodontitis?
Although each of the listed factors can play a role in the development of periodontal disease (gingivitis or periodontitis), the classification of chronic periodontitis is most often associated with disease caused by build up of dental plaque due to poor oral hygiene. The other factors listed above may lead to recession or gingivitis, but are not likely to lead to bone loss, which is required in classifying a disease as periodontitis.
Whether a person develops periodontitis is purely determined by genetics.
Although genetics are an important disposing factor for periodontitis, the disease may also develop due to other local or systemic factors that are unrelated to genetic causes.
Which of the following characterize periodontal disease as found in a diabetic?
Those individuals with diabetes in general exhibit more inflammation and delayed wound healing than those without. This leads to a more severe and rapidly progressing form of periodontitis that leads to faster bone loss and delayed healing compared to a non-diabetic patient. This is the case regardless of the amount of dental plaque each patient exhibits.
