Abstract: This invention is related to a dental retractor including a body part having a handle portion, a neck portion extending from the handle portion, and a mirror part having a micro mirror, which is detachably attached to an end of the neck portion, such that the projection can be inserted in to a hole formed at a surgical site to observe an inside the hole. According to the present invention, since the dental retractor has the mirror part for observing the interior of the oral cavity, the number of operations, the number of persons required for the operation and the working time are reduced and it is not necessary to separately use a dental mirror. In addition, since the dental retractor has a mirror such as a micro mirror at the head portion, a doctor or other practitioner/technician can use the other hand to perform a medical examination.
