Effect of Nano Care Gold on Marginal Integrity of Resin Composite

Marginal Integrity of Resin Composite Restoration With & Without Surface Pretreatment by Gold & Silver Nanoparticles Versus Chlorhexidine in Class II Cavities Randomized Controlled Trial

The aim of this study to detect the effect of Nano Care Gold on marginal integrity of resin composite restoration

This study will be divided into 3 groups (control, Nano Care Gold, Chlorhexidine). Both materials will be used as a surface pre-treatment. Their effect on marginal integrity will be evaluated through evaluation of marginal adaptation, marginal staining, post-operative sensitivity. The follow up period is one year

Inclusion Criteria:

• (1) Patients with at least two class II cavities (2) 17-50 years old (3) Males or females (4) Good or hygiene (5) Good general health (6) Cooperative patients (7) Subjects who signed the informed consent

Exclusion Criteria:

1. Patients younger than 17 years or older than 50 years old
