  1. Approximately what percentage of U.S. adults floss daily?
  1. Caries result from acid erosion of hard surfaces of the teeth due to metabolic acids produced from the metabolism of simple sugars.
  1. How many decayed, missing, and treated (DMFT) teeth does the average American adult have?
  1. In 2009, the number of emergency room visits related to dental conditions was:
  1. The prevalence of periodontitis has been estimated to be over ______% of U.S. adults?
  1. The prevalence distribution of periodontal disease severity and disease progression in treated and untreated populations suggests that periodontal disease is bacterially initiated and disease progression is propagated by host factors.
  1. Short-term studies and observational trials have not demonstrated that interdental cleaning leads to increased dental health and decreased tooth loss.
  1. All of the following individuals/organizations have issued recent statements reaffirming the importance of interdental cleaning for oral health EXCEPT:
  1. A caries risk assessment tool that can be used in the evaluation of children and adults is:
  1. ______________ is the largest modifiable risk factor for periodontal disease progression.
  1. Current ADA rcommendations for oral hygiene include:
  1. Due to their superior bristle flexibility, toothbrushes with soft bristles are associated with greater subgingival and interproximal plaque removal.
  1. In a study of twins, use of dental floss was associated with decreased interdental plaque and bleeding and a shift in the bacterial microflora to a healthier, less pathogenic bacteria.
  1. Interdental brushes have been shown to remove _________ plaque interproximally when compared to floss and have demonstrated ______________ reductions in interproximal probing depth and gingival bleeding.
  1. Mouthrinses containing ____________ have demonstrated efficacy in reducing signs of gingival inflammation and gingival bleeding when used as an adjunct to toothbrushing.
  1. Improvement in effectiveness of oral hygiene measures requires multiple rounds of oral hygiene instruction and reinforcement over time.
  1. Psychological interventions that have shown an improved effect on patient performance of oral hygiene measures include:
