Abstract: Objective To observe the effect of wheel running and treadmill running on the cognitive functioning of rats after the extraction of a molar.Methods Thirty-two Sprague-Dawley rats were randomly divided into a control group (group C,n =8),a molar extraction group (ML group,n =8),a wheel running pretreatment group (W-ML group,n=8) and a treadmill running pretreatment group (T-ML group,n =8).The rats in the T-ML and W-ML groups practiced wheel running and treadmill running for 1 week,then they and the rats in the ML group received molar extraction surgery.One week later,a passive avoidance test was used to evaluate the cognitive functioning of all of the rats.Results No significant differences were found in the groups' average latency I times,but the average latency II time of the ML group was significantly shorter.There was no significant difference in the average latency II times of the T-ML and W-ML groups.Conclusion Either wheel running or treadmill running can promote learning and memory after molar loss by oral surgery,at least in rats.
