hello i am a dental asssistant, while cleaning a patients provisional tooth, a little piece of cement jumped off and hit right above my eye.. really close to it.. i didnt feel anythng go in... the patient is a high risk patient... and the provisional had been in his mouth, and earlier in the appointment there was blood. after the incident happened, I looked in a mirror and there was nothing there.. not a mark... and i didnt feel anything go in, should I worry?
