تقييم بتر لب الأرحاء المؤقتة عند استعمال بولي كربوكسيلات الزنك كحشوة قاعدية

Abstract EN

Background& Objective: The aim of this study was to evaluate the clinical and radio graphical success rates of ferric sulfate pulpotomy in human second mandibular primary molar teeth when zinc polycarboxylate cement is used as a sub base material.

Materials & Methods: Ferric sulfate pulpotomies were performed on 56 primary molars in healthy children aged 6_8 years, following the pulpotomy procedure, the molars were randomly divided in tow groups, In group 1(29 molars) zinc polycarboxylate cement was placed over the pulpal stumps and in group 2(27 molars)a zinc oxide and eugenol paste cement was placed.

The teeth of both groups were restored with stainless steel crowns.

Results: Clinical and radio graphical success rate in 9 months evaluation of zinc polycarboxylate group were 93.1% and 72.4% respectively, in the zinc oxide and eugenol group clinical and radio graphical success rate were 92.6% and 81.5% respectively..

There were no statistical differences between the two groups, either clinically or radiographically.

Conclusions: In ferric sulfate pulpotomy using zinc polycarboxylate cements as a sub base is not preferable to zinc oxide eugenol cement
