Abstract: Post-accidental exposure refers to injuries caused by stabbing and cutting with sharp objects, as well as skin and mucosal exposure to blood and contaminating fluids.  The aim of this study to assess the level of knowledge and attitudes of dental nurses regarding prophylaxis after accidental exposure to blood-borne infections. Material and methods: A cross-sectional study was carried out on a group of dental nurses working in dental offices in the city of Iaşi. The subjects completed a questionnaire that includes questions about skin lesions that can occur accidentally during dental procedures, the causes and means by which the accident occurred, questions that evaluate the level of knowledge regarding the post-accidental exposure protocol to blood-borne infections, assesses knowledge regarding immunization. Data were analysed with SPSS version 20.0 software (SPSS, Chicago, IL, USA). Results: The study group was formed of 26 dental nurses from Iași. 42.3% fell into the 20-30 age group, 30.8% – 31–40-year-old group, 23.1% – 41-50 year old group and 3.8% in the “over 50” age group. 82% from the urban area. 85% of the participants know what a skin lesion is, 38.1% suffered stabbing or cutting accidents, most frequent accidents occurred during the use of the syringe needle (65.4%). 84.6% of nurses admit that both HIV, hepatitis B and hepatitis C are transmitted through blood. Only 50% of the nurses are vaccinated against the hepatitis B virus. 80.8% of the nurses knows compliance with Universal Precautions, is mandatory for all medical personnel and applies to all patients. Conclusions: Nurses who work in dental surgeries and have more than 6 years of experience have a level of knowledge and attitudes regarding both the prevention of stabbing/cutting accidents and post-exposure prophylaxis measures to blood-borne infections.  Although the level of knowledge is good, the applicability of measures to prevent accidents and post-exposure prophylaxis leaves something to be desired.
