The aim of this study was to investigate the cross-infection control procedures used by Turkish orthodontists. A questionnaire was mailed to 268 orthodontists to determine the attitude toward infection-control procedures. Responses were received from 194 orthodontists, and the reply data were analyzed. Of the 194 orthodontists who completed and returned the questionnaire, 77.3% had been vaccinated for hepatitis B, and 24.2% always wear a mask when treating their patients. While 48.5% of the respondent orthodontists always wear gloves, 4.1% never wear gloves.
