This study aimed to survey and evaluate knowledge and practice of Dental Safety among Thai Dentists in public hospitals. Eight hundred and fifty-five dentists representing 855 public hospitals were asked to complete the online-survey questionnaire enclosed with details of the study along with the consent letter. The questionnaire regarding Dental Safety Goals and Guidelines (DSGG) classified into 5 categories- Safe Communication, Safe Dental Treatment, Safe Infection Control, Safe Record and Risk Management. Response options were graded on a 4-point-Likert scale ranging from 0 to 3. The non-respondents received a reminder email after the second week. The data was analyzed by descriptive statistics using Statistical Package for Social Science (SPSS, version 22.0). Two hundred and twenty-seven dentists returned the DSGG questionnaire. A response rate of 26.5 % was achieved. Participants were in hospitals in every region of Thailand. Approximately 57 % of them were DSGG-survey-participants in the last two years. The results indicating the highest DSGG compliance is Patient Medical History taking (score=2.90±0.22) and the lowest DSGG compliance is Respiratory Hygiene (score=1.58±1.13). The overall responses indicated that most dentists had good practice in regards to DSGG.
