Abstract Post-operative oedema is a common observation seen by patients and oral surgeons. Factors affecting post-operative oedema were surveyed. The present study compared the effect of handpiece speed on post-operative oedema after surgical removal of impacted mandibular third molar. The present study compared the effect of low speed handpiece 30000 rpm versus high-speed handpiece 120000 rpm, mounted on electric micro motor, on post-operative oedema. The study was conducted on 30 healthy patients, who have bilateral mesioangular mandibular third molar class Ι position B. The study group included 22 males and 8 females .The age was ranging from 18 to 30 years with mean of 24.4 years. During surgical procedure under local anesthesia, bone is removed by low speed handpiece on one side and high speed handpiece on the other side so patients themselves act as control group of the study. Oedema was measured by two methods: first were tape measurements of four lines of predetermined anatomical landmarks. These lines cover most area of facial oedema. The second method was the use of caliper in the lingual embrasure between lower first and second mandibular molar, while the other arm of the caliper was adjusted lightly the skin of the cheek. The distance between the tips of the caliper arms measured using graduated tape. Trismus was measured by measuring the distance from incisal edge of maxillary right central incisor to the incisal edge of mandibular right central incisor by using Boly gauge. |
