Overview
Brief Summary
Evaluation of PMMA pediatric crowns
Detailed Description
The aim of the present study is to evaluate the PMMA crowns regarding the following aspects:
I. Clinical evaluation of PMMA crowns regarding wear of opposing teeth when compared to zirconia crowns and stainless steel crowns after 6 months, and 12 months.
II. Color stability of PMMA crowns and zirconia crowns after 6 months, and 12 months.
III. Gingival health of restored teeth after 6 months, and 12 months. IV. Patient's satisfaction regarding the appearance and clinical performance of PMMA crowns when compared to stainless steel crowns and zirconia crowns through a given questionnaire.
