  1. C. Sugar is converted by bacteria into acid which destroys the tooth surface. There is a certain level of acidity in the mouth where the minerals begin to be stripped from the enamel faster than our saliva can replenish. As a result, our defenses are lowered and cavities begin to form.
  1. E. All of the above
  1. C. The jaw joint. The TMJ stands for temporomandibular joint. This is a complex joint with many functioning components. You may have heard someone in the past state that they have “TMJ”. All of us have TMJ. In fact, we all have two TMJ’s. What they are likely referring to is TMD which stands for temporomandibular dysfunction. This is a group of disorders relating to the TMJ.
  1. D. 20. The permanent dentition (including the 4 wisdom teeth) consists of 32 teeth.
  1. A. Periodontics. A dentist that specializes in Periodontics is termed a periodontist. An endodontist is a dentist that specializes in the removal of tooth pulp. A prosthodontist specializes in the artificial replacement of teeth and gums.
  1. D. Upper 1st molar
  1. B. Circular. Small circles have been shown to be the most effective method for toothbrushing. Dr. Charles C. Bass created the “Bass Method” of toothbrushing and decades later dentists and hygienists still teach the fundamentals of this technique.
  1. B. False. Fluoride in toothpaste works to protect tooth enamel. Fluoride is taken up by the enamel and can be instrumental in the defense against tooth decay. After brushing, small amounts of toothpaste containing fluoride remain in the mouth. A mouthful of water to rinse the mouth dilutes this beneficial residue significantly and can be counterproductive.
  1. A. We produce less saliva as we age. This is false. Many older adults have reduced salivary flow but this is not an inherent part of aging. Medications are the most common cause of dry mouth and many older adults take several medications daily. Older Americans are more prone to tooth decay on the roots of teeth. This is mainly due to a few factors. First, we are keeping our teeth longer. Second, many people have receding gums. As we age, more and more root surface shows allowing for a new surface at risk for decay.
  1. A. 50%. This seems like a high number doesn’t it? Back then it was very common to give a set of dentures as a wedding present! We sure have come a long way.
