The objective of this investigative study is to provide information on the type of public postgraduate training in oral surgery currently being taught in Spain. A descriptive study is made relating to the theoretical and practical syllabuses of the different Masters, through questionnaires answered by students who had previously completed the postgraduate course. Later, a possible relationship between age, sex and previous training in dentistry or stomatology was explored. The results show a poorer preparation in subjects related to the planning and carrying out of treatment of salivary gland pathologies, transposition of the inferior alveolar nerve, treatment of oral tumors, and the treatment planning for osteitis and osteomyelitis. There is a difference between the sexes in a number of answers, where females give higher scores. The stomatologist scores higher in treatment planning for complicated extractions and in the carrying out of dental transplants. It seems that the older the student, the less prepared they are to carry out a treatment plan which includes a biopsy, and the better prepared they are to treat dental emergencies, dentoalveolar trauma, osteitis and osteomyelitis. We can conclude principally that the students give a generally positive evaluation of the oral surgical training, both theoretical and practical, except in the more complex topic areas which appear to relate to the maxillofacial surgeons.
