Abstract:
Objective:To evaluate the influence of platelet-rich plasma(PRP) on periodontal healing of replanted teeth in 6 Beagle dogs.Methods:The second incisors were pulled out and re-implanted after 60 min dry storage.In group A,PRP were applied before replantation,and 7days later the teeth received root canal treatment.In group B,PRP were applied before replantation either,but without root canal treatment.In group C,PRP were not applied and 7 days later,the teeth received root canal treatment.In group D,no PRP were applied and no root canal treatment.All the dogs were sacrificed after 12 weeks and the histological parameters were observed.Results:There were no significant differences between group A and C.Group B showed a lower incidence of ankylosis,and higher incidence of healed PDL compared with group D.Conclusion:Under the definite condition,PRP can help to decrease the incidence of ankylosis and increase the incidence of healed PDL in groups that the pulps were not removed.
