Objectives: To evaluate dentists' knowledge and experience about life-threatening medical emergencies they may encounter in daily practice and question the competency of using relevant equipment. Material and Methods:The study included a 15-question multiple-choice test aimed to evaluate dentists' medical practice based on current cardiopulmonary resuscitation (CPR) guidelines, and a 29-question survey to identify the causes of incompetence detected.The data were collected through face-to-face interviews or e-mail. Results:In total, 475 dentists were contacted for the survey and, 363 agreed to participate.For the theoric questions, the mean score of the participants was 47.1+-15.9(median (IQR): 46.2).The relationship between CPR training and the total score was significant (p: 0.00).There was no significant relationship between working experience and the score obtained (p: 0.14).Of respondents, 22.3% reported feeling competent in CPR, 78.8% believed dentists should know CPR, 17.9% reported being knowledgeable in automated external defibrillator (AED) use, 23.4% reported feeling competent in managing chest pain, 37.7% reported feeling competent in managing anaphylaxis, 47.9% stated that their emergency drugs and equipment were regularly checked.Conclusions: Dentists in Turkey need to be adequately prepared for medical emergencies.Pre-and post-graduate education may not sufficient, and CPR and medical emergencies training should be repeated after graduation to ensure that knowledge and skills are maintained.In addition, it is necessary to include an AED device, to be competent in the indications of all equipment and drugs, to provide training for the personnel, and to develop and regularly monitor emergency planning.
