Abstract

Dental health care workers are always posed to the risk of croos-infection. The taken impressions are one of the possible ways of this type of infection; therefore this study was aimed to evaluate the knowledge, attitude, and practice of Tabriz general denal practitioners (GDPs) on the methods of disinfecting impressions. In this study 183 individuals were selected and the questionnaire filled out by them. The collected data was reported by descriptive statistics, Mann-Whitney U test and Kruskal–Wallis by SPSS.15. The mean knowledge grade was 9.4 (2 to 4) (23.4% poor knowledge level, 74.5% moderate and 2.2% good). At all attitude questions 80% of GDPs agreed. The mean practice grade was 5.1 (1 to 9) (13% of GDPs poor practice level, 71.2% moderate, and 14.7% good). There was no significant difference between the practice of dentist in relation to variables like the clinical experience and gender (P>0.05). Also, a significant difference between the knowledge of dentist with 10-20 years clinical experience was found (P<0.05). Totally, the knowledge level of dentists was at moderate levels and their attitude and practice level was moderate to high.
