| Score of 2 point discrimination test. Timepoint: day preoperative and then on days1,3,7,14,21,28 and 35 postoperative. Method of measurement: The points of calipers are held against the skin at different distances from each other. The test determines the minimal distance at which the patient can distinguish whether one or two points are in contact with the skin. This distance starts at 10 mm in the upper lip and 20 mm in the nasolabial fold, and gradually decreases by one millimeter each time the test is performed, until patient feel the 2 points as one point. The amount of distance that the patient first senses two points as one point is considered as an outcome. We will do this process 3 times and consider its average.;Score of brush directional stroke test. Timepoint: Day preoperative and then on days1,3,7,14,21,28 and 35 postoperative. Method of measurement: brush directional stroke test consisted of performing ten horizontal or vertical movements with a micro brush tip on the marked points (about 1 cm) and ask for the patient to report the direction. The number of correct answers is recorded from the number of 10 tests performed.;Score of thermal discrimination test. Timepoint: Day preoperative and then on days1,3,7,14,21,28 and 35 postoperative. Method of measurement: In this test, small glass tubes filled with cold water (15 degrees) and hot water (50 degrees) are used. The end of the tube is in contact with the desired point on the skin for 5 seconds and the patient is asked about the water temperature (hot or cold). Finally, after 10 tests, the number of correct answers is considered as the patient's score.;Score of sharp blunt discrimination. Timepoint: Day preoperative and then on days1,3,7,14,21,28 and 35 postoperative. Method of measurement: This test is performed using a dental explorer 17/23 to test the sharp sense and a periodontal probe for the blunt sense. One of these two tools contacts the target point with a gentle pressure and the patien | — |
