post operative sensitivity following composite restoration .

Post operative sensitivity is typically characrized by pain or discomfort with cold and hot following tooth restoration

the main cause is adhesion problem , so following systematic Approach re-treatment grantees success in such cases cases .

Adhesions tricks :

1- selective enamel etch using gel type etchant " polymer based"

2- 2 coat of universal bond with agitation to improve adhesive penetration with No curing in between

" if you are 2 step self etch adhesive using take your time in priming step "

3- cure your adhesive layer for 20 secs at least intermittently

" 5secs 4 cycles "

4-apply very thin layer of high filled flowable composite " injectable composite " or bulkfill flow as resin coat to act as hydrophobic layer and ensure No voids no gabs between adhesive layer and composite.

5- follow successive cuspal build up technique . cusp by cusp technique with Low shrinking composite material
