Evaluating the knowledge and practice of Yazd general dentists toward needle stick injuries (NSI) in 2022

 Injuries caused by sharps and needles are one of the most important problems that put dentists in the throes of exposure to dangerous blood-borne diseases. This study aimed to evaluate the knowledge and practice of dentists in Yazd about needle stick injuries in 2022.

 In this cross-sectional study, a researcher-made questionnaire was used. The questionnaire encompassed three parts including demographic characteristics (age, gender, injury history, work history), performance (11 questions), and awareness (14 questions). It was completed by 165 dentists. Data were analyzed using t-test and chi-square, one-way ANOVA and Pearson correlation by SPSS 25. Ethical considerations were also observed at all stages of the study.

 In this study, 57% of dentists reported to have previous needle stick injuries. The mean scores of knowledges and practice were 24.24±5.17 and 22.62± 3.42 of the maximum scores of 28 and 33, respectively. Knowledge score had a statistically significant relationship only with the workplace of dentist activity (P <0.001); while practice score had a statistically significant relationship with gender, workplace, and history of needle stick injury. In addition, a significant correlation was found between knowledge and practice scores (P <0.001).

 Based on the findings, although dentists' knowledge toward NSI was acceptable, the practice was inadequate. The related educational programs could reinforce their practice.
