Study summary

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

Read the detailed description

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

Study arms

  • Experimental
    Nano Care Gold

    Silver and Gold nano particles suspended in 70 % isopropyl alcohol. It will be used for cavity pre-treatment. This arm will be compared with no intervention (negative control).

    Other: Nano Care Gold · Other: No intervention

  • Active comparator
    Chlorhexidine

    2% chlorhexidine gluconate solution will be applied to prepared cavity followed by adhesive system then resin composite. This arm will be compared with no intervention (negative control).

    Other: No intervention · Other: Chlorhexidine

Interventions

  • OtherNano Care Gold

    Mixture of Gold and Silver nano particles suspended in 70 % Isopropyl alcohol. This group will be compared with no intervention group.

    Also known as: Silver and Gold nano particles

  • OtherNo intervention

    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

    Also known as: Negative control

  • OtherChlorhexidine

    2 % chlorhexidine gluconate. This group will be compared with no intervention group.

    Also known as: chlorhexidine gluconate

What researchers measure

Primary outcomes

  1. 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

Secondary outcomes

  1. 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

  2. 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
