Objective: Determine the presence of ?burnout? syndrome and characteristic personality patterns in the students and faculty of three graduate programs in Dentistry at the University of Barcelona: Department of Oral Surgery and Implantology, Department of Orthodontics and Department of Integrated Dentistry. Materials and Methods: The study was carried out in 78 dentists. The level of ?burnout? was evaluated using the Maslach Burnout Inventory, socio-demographic variables and, finally, the personality test. Results: Oral surgeons constituted the group of highlevel ?burnout?. The profile of an individual with a propensity to ?burn out? is a single man, with a median age of 27, that is in the first years of the graduate program and that combines studies with 30 hours of clinical practice and/or other work (p<0,05). Narcissistic and borderline are the types of personality most frequently found in the individuals that present ?burnout? syndrome (p<0,05). Conclusions: In general, no high levels of ?burnout? were registered in the studied population, only 2-3%, if applying strict definition of ?burnout?, and 10% if these criteria were amplified. We believe it is necessary to identify the individuals with a tendency towards ?burnout?, in order to establish preventive measures and avoid future negative behaviour at work as well as at the personal level.
