Details and patient eligibility

About

The aim of the current study is to assess the shade matching potential of single shade universal resin composite versus conventional nanohybrid resin composite in class IV restorations after bleaching

Full description

The use of a dental material that can blend into the surrounding tooth structure is increasing in popularity . A new technology , smart chromatic technology , has been introduced as the shade matching composite called omnichroma . Omnichroma has the ability to match the new lighter shade of the bleached teeth unlike the conventional composite . In this study , an investigation will be done to evaluate if this new technology will help to preserve the tooth structure and be more conservative , by avoiding the removal of the old anterior restorations after bleaching
