We have reviewed the records of 114 patients receiving minor surgical procedures as outpatients in the department of Pediatric Dentistry in Kyushu University Dental Hospital from 2003 to 2006.
The mean of number of outpatients with minor surgical procedures in our clinic was about 30 per year, and the male to females ratio was 2: 1. The number of procedures was follows. The extraction of impacted supernumerary teeth accounted for 60 percent of the total, followed by exposure of impacted permanent teeth, application of traction and extraction.
Regarding extraction of impacted excessive teeth, the number of impacted supernumerary teeth was one, the while direction of the dental crown was inverted, and the impacted site was the palatal side in the majority of the cases. Average surgical time was about 40 minutes.
We classified the position of The impacted supernumerary teeth using panorama X-ray films. This classification was useful for the determination of difficulty level of the extraction. The preoperative examination, including blood sampling was effective in assessment of the reaction of the patients before surgery.
