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

Mixture of Gold and Silver nano particles suspended in 70 % Isopropyl alcohol. This group will be compared with no intervention group.
No intervention will be applied in this group. It will be the negative comparator. In this group only the standard of care will be applied, which means the steps will be cavity preparation followed by adhesive system then resin composite without any surface pre-treatment
2 % chlorhexidine gluconate. This group will be compared with no intervention group.

Marginal adaptation
It will be measured by FDI probe and Digora x-ray machine. FDI Scoring system (categorical) 5 steps(3 accepted, 2 unaccepted) will be used to evaluate the outcome of measuring device
Time frame: 1 year
Marginal staining
Visual inspection and Photographs will be used to measure the outcome. FDI Scoring system(categorical) 5 steps(3 accepted, 2 unaccepted) will be used to evaluate the outcome
Time frame: 1 year
Post operative sensitivity
A blast of cold air will be used to evaluate the restoration. FDI Scoring system(categorical) 5 steps(3 accepted, 2 unaccepted) will be used to determine the restoration fit in which category.
Time frame: 1 year
