Introduction. Benign paroxysmal positional vertigo (BPPV) is the most common type of vertigo with an annual prevalence of 1.6% in the general population. It can be caused by head injury. BPPV are triggered when certain head movements, as happens to lie in supine during the dental encounter. The objetive of this study is to determine the incidence of BPPV presentation during dental procedures. Additionally, the study examines the incidence of iatrogenic BPPV after head injury made ??with the osteotome during dental procedures. Material and methods. The study was conducted in a comprehensive Dental Center where consecutive pacientes are recruited. This is a prospective observational study. We investigated whether the patients would be lying supine were afraid of dizzy, and also studied the onset of dizziness in patients, when laid on supine position or if there was vertigo in the days subsequent to dental procedures in patients who used the osteotome. We excluded patients younger than 30 years and those with vestibular history. Results. We found that 1.7% of patients over 30 years are afraid to present vertigo if they will be lying in a horizontal position, but only 0.17% of them have presented a real BPPV in doing so. 1.3% of the subjects in which the osteotome was used during the dental procedure had an iatrogenic BPPV. Discussion. BPPV can occur in patients who lie down in horizontal situation for dental work. Furthermore, we found that use of the osteotome in dentistry can be an iatrogenic factor in BPPV.
