A 48-year-old female patient presented complaining of painful sensitivity on the lower right side of her mouth. Tooth No. 29 had an existing Class II composite restoration that had been placed by another dentist several years ago. I could tell by a simple visual inspection that the margins were failing. I decided to replace the restoration in case secondary caries had developed; the patient agreed.,I removed the composite, some microleakage and decay. My go-to rotary instruments for cavity preparation are disposable NeoDiamonds (Microcopy) because I get a fresh, efficiently cutting bur every time.,To achieve an optimal contact and anatomy for this case, I used a Composi-Tight 3D XR sectional matrix (Garrison Dental). Then I placed TheraCal LC (BISCO) over the deep area where I had removed decay to create a barrier and protect the pulp. I’ve found it to be very effective at eliminating postoperative sensitivity and at promoting healing.,For added protection, I chose to use a sandwich technique, placing EQUIA Forte (GC America), a conventional glass ionomer that will release fluoride and can help hypermineralize the damaged tooth. The remaining enamel was acid-etched with Select HV Etch (BISCO). ALL-BOND UNIVERSAL adhesive (BISCO) was then applied, followed by light polymerization using a VALO (Ultradent) LED curing light. I then placed Admira Fusion (VOCO) as the final layer. After curing, the composite surface needed only minimal finishing to produce a high luster.,The patient was thrilled that the sensitivity was gone and her tooth looked great.
