The validity of the questionnaire by 10 dentists was CVR = 0.83 and its reliability by Crombach's alpha was 0.87. The questionnaires were completed by referring to the private office of dentists and in the presence of the examiner. After receiving the answers of the first step, an instructional video on waste disposal methods in dental offices was sent to them in WhatsApp Messenger, if they did not have access to WhatsApp Messenger, a CD or flash containing this instructional video was delivered to them and The next visit was scheduled for a week later.
