title: Differences in knowledge related to dental implants between patients with and without a treatment history of dental implants.
abstract: OBJECTIVE
  This aim of this study was to investigate the differences between patients with and without a treatment history of dental implants by use of a questionnaire survey in order to determine the information that is required for patients undergoing dental implants.
  
  
  METHODS
  The questionnaires were given to 4512 patients who visited the Tokyo Medical and Dental University Hospital for oral implants between January 2012 and December 2014, and 2972 (66%) valid questionnaires were collected.
  
  
  RESULTS
  There were 857 patients with a treatment history of dental implants and 2115 patients without. "Preservation of an adjacent tooth" was the reason that 32% of these patients chose implant therapy, and the patients without treatment history were significantly higher than the patients with one. Significantly, more patients without a treatment history of dental implants selected the after-effects of surgery and pain after surgery as their main concerns for implant therapy compared to those with a treatment history. In the question "Pain after surgery," the patients without treatment history did not know significantly lower than the patients with one.
  
  
  CONCLUSIONS
  Patients without a treatment history of dental implants placed more importance on the preservation of healthy teeth. Because patients, in particular those without a treatment history of dental implants, are anxious about surgery, we should provide them with more information on treatment than we already do and explain the risks of treatment to them. To keep the credence between doctors and patients, informed consent and patient education on treatment are six important concerns.
