Abstract:
Objective To discuss the clinical effect of different scaffold in pulp vascular regeneration . Methods 22 young permanent teeth with periapical lesions were randomly divided into observation group and control group,11cases in each group .After the disinfection protocol was completed , the apexes of the control group were irritated to initiate bleeding to produce a blood clot to achieve pulp revascularization ,while the observation group used platelet rich plasma as physical scaffold to operate pulp revasculrization .Results In the control group , the two patients showed painful tooth at 1 and 8 months,the three patients showed healed periapical lesions and narrowed apical foramen at 12 and 18 months ,the six patients showed healed periapical lesions and closure of the apical fora -men at 12 and 18 months.In the observation group ,the three patients showed painful tooth at 1,3 and 8 months,the four patients showed healed periapical lesions and narrowed apical foramen at 12 and 18 months,the four patients showed healed periapical lesions and closure of the apical foramen at 12 and 18 months.There was no statistically significant difference between the observation group and control group by Fisher's exact probabilities (P=1.000). Conclusion Platelet rich plasma is potentially an ideal scaffold for pulp revascularization .
