As a result, the following students were found to comply with this precautionary guideline well: students thinking that it is possible to protect themselves from diseases by comply with the infection control guideline; students thinking that their fellow students well complying with hand washing and wearing the protective device are very exemplary; students sufficiently provided with the protective device and having no difficulty using it; students practicing at the practice institution equipped with the infection control guideline book; students practicing at the institution staffed with the infection control officer or armed with the infection control department; and students informed of whether or not the patient was infectious in giving cooperation about medical treatment.

Of the students experienced in stab by needle at the time of practicing, the number of the students provided with not medical treatment were found to be high at the institution unequipped with the infection control guideline book and at the institution with no infection control officer or department. The report to the infection control officer about stab by needle was found to be high in the group of students practicing at the institution equipped with the infection control guideline book and staffed with the infection control officer or armed with the infection control department.
It was found that in the clinical practice of students majoring in dental hygiene, the level of their compliance with the infection control guideline had a higher correlation with factors such as financial support and organized support than the level of their experience and the level of their understanding.
