Abstract:
Objective The study is aimed to compare the analgesic effect of two preemptive analgesia programs (partial closure / fenbid po.) in patients undergoing extraction of the impacted mandibular third molar.Methods Sixty-two patients who visited our outpatient center from December 2009 to September 2010 with impacted mandibular third molar were randomly divided into two groups.Patients after extraction were given 3％ mepivacaine injecting immediately under the periosteum for partial closure in the experimental group,while them in the control group,fenbid 300 mg were administrated at 2 hours after operation and once more every 6 hours.Pain sores at 2 h,4 h,8 h,12 h,24 h,48 h after operation were recorded with VAS (visual analogue scale) and parallel groups repeated measures design of longitudinal studies was carried out for statistical comparison between the two groups:studies in which individuals were measured repeatedly through after surgical operation time (2 h,4 h,… ).Results At the time of 2 hours after the operation,the average pain scores of the mepivacaine group (2.5 ± 1.1 ) was lower than the pain scores of the fenbid group (2.8 ± 1.1 ).But there was no significant difference in pain scores between two groups within 2 - 48 h after operation ( P ＞ 0.05 ).Also no statistically relationship between the pain scores and the factors such as age,sex and groups.About the time after operation,between 48 h and 12 h,8 h,4 h,2 h,the pain scores were significantly different ( P ＜ 0.05 ).Conclusions The study suggests that 3％ mepivacaine partial closure immediately after extraction of the impacted mandibular third molar chould have the same analgesic effect as the fenbid.
