Accidents with potentially biologically contaminated material in students from the course of odontology in the interior of the State of Paraná.
This is an exploratory descriptive study with a quantitative analysis approach, which objective was to study the occurrence of accidents with potentially biologically contaminated material and the risk factors involving the students from the Course of Odontology in the interior of the State of Paraná, Brazil. For the data collection, a questionnaire was applied containing open and closed questions. This instrument was applied to the students after the observation of the ethical-legal aspects. One hundred and seventy two students from the 3rd, 4th and 5th years of the course participated in the study. From these students, 122 (70.9%) alleged to have suffered accidental exposition with potentially contaminated material. Most of the students that suffered accidental exposition were female (61.0%) and they were at the 5th year of the course, the predominant age was between 20 and 26 years old (86.1%). The number of accidents mentioned by the 122 students summed 448. The most frequent kind of accident occurrences was the intact skin, followed by the exposition of mucous membrane and the percutaneous accident which made a total average of 2.6 accidents for each student and the average of 0.23 for percutaneous accidents alone. The most affected areas in these expositions were the eyes, hands and fingers, and the drills and the anesthesia needles were mentioned as the main objects that causes these accidents. The most found occurrence situation was the common action of using an instrument and at the moment of cleaning them. It was in the courses of Integrated Clinic, Periodontics and Dentistics that happened most of the expositions. As for the severity of the cases, 41.8% of the expositions were considered superficial and 22.1% were moderate. Only 10.7% of the students exposed to some kind of injury, sought for a service of checking and possible treatment; 88.6% of the persons received the three doses of the hepatitis B vaccine. It was observed though, that students didn?t usually make use of the Equipments of Individual Protection. The use of the protection glasses and gloves, made of thick rubber at the time of cleaning the materials were the most neglectful. This study allowed us to conclude that the exposition risk to biological material is imminent for this work category and that it is necessary to establish urgent intervention strategies on an institutional or academic level in order to reduce these risks.
