Postoperative Hypersensitivity and Digital Radiographic Assessment of a Zinc Modified Versus a Conventional Glass Ionomer Cement in Deep Carious Lesion: Randomized Controlled Clinical Trial

Study Overview
=================
Brief Summary
-----------------
The study aim to evaluate the difference between the effect of zinc modified glass ionomer and conventional glass ionomer on the success of partial caries removel technique

Detailed Description
-----------------
The zinc ion has an antibacterial effect which could increase the success of partial caries removel technique by decreasing the bactrial population .
