Background: Knowledge about dental/medical ethics and Consumer Protection Act (CPA) is very essential now a day as it is the era of litigations. Aim: To know about the awareness of provisions of Consumer Protection Act among practicing dentists in Patna. Methods: In a cross sectional study, a total of 200 dental professionals were surveyed using a self administered structured questionnaire. The questionnaire comprised of 19 questions about the awareness of consumer protection art (CPA) and whether these professionals were following the recommendations of CPA. Results: The awareness scores were significantly lower among dental professionals. Among dental professionals postgraduates were more aware compared to graduates. In the present study 96% dentists knew that for a patient 10 years of age, consent for examination is taken from parent / guardian, 89% of dentists were aware that they should always take consent from patient/patient's guardian once they have explained the treatment procedures. Whereas only 38% dentists knew that after treatment is over the informed consent form should be preserved by the dentist which appeared to be a matter of concern. Conclusions: Though post graduates professionals have more awareness of CPA compared to graduate professionals, considering the present scenario, better knowledge of CPA is necessary for both professionals in order to be on the safer side.
