title: Prescribed medication taken by patients attending general dental practice: changes over 20 years.
abstract: BACKGROUND
  Drug therapy can influence treatment planning and provision of dental care by general dental practitioners. There is little published information regarding the types of drug therapy taken by patients presenting for dental treatment in the United Kingdom.
  
  
  OBJECTIVE
  To record the drug therapy taken by patients presenting to general dental practice in 1995 and 2005 and compare to data reported in 1984.
  
  
  METHODS
  General dental practice.
  
  
  METHODS
  Prospective cross-sectional study.
  
  
  METHODS
  Patients presenting to general dental practices in 1995 and 2005 were questioned regarding their current drug therapy. Patients' general medical practitioners were contacted if their drug history was unclear.
  
  
  RESULTS
  35%, 21.1% and 43.8% of patients were taking medications in 1984, 1995 and 2005 respectively. Statistically significant increases in the proportion taking three or more medications were evident in both 1995 and 2005.
  
  
  CONCLUSIONS
  In 2005 more patients presenting to dental practice were taking medications compared to 1984. There is an increasing trend toward polypharmacy. Therefore it is important to maintain a contemporaneous knowledge of pharmacology and drug interactions to ensure the provision of safe dental care.
