Pre-operative radiograph. Note the carious lesion on the distal of tooth No. 4.

The completed preparation on tooth No. 4 has been isolated using a rubber dam and the Palodent® Plus Sectional Matrix System.

Caulk® 34% Tooth Conditioner Gel is applied to the preparation of tooth No. 4. Even using the small blue syringe tip it is difficult to place phosphoric acid on enamel only. With Prime&Bond Elect® adhesive practitioners can select any etching mode; total-etch, self-etch, or selective-etch without negatively impacting bond strengths or increasing the likelihood of post-operative sensitivity.

Prime&Bond Elect® adhesive is scrubbed into the preparation on tooth No. 4 for 20-seconds, then air dried for 5-seconds to evaporate the solvent.

The first restorative layer is placed using SureFil® SDR® flow bulk fill flowable. SureFil® SDR® flow bulk fill flowable can be placed in up to 4mm increments followed by a 20-second light cure. Within a few seconds, dispensed SureFil® SDR® flow bulk fill flowable material will self-level, eliminating the need for further manipulation with hand instruments.

The final restorative layer (at least the occlusal 2mm of the restoration) is placed using TPH Spectra® Universal Composite. Shown is the high-viscosity (HV) formulation which provides a stiffer handling composite. TPH Spectra® should be light cured for 20-seconds after each increment is placed.

After light curing the final occlusal layer of composite, the Palodent® Plus Sectional Matrix and rubber dam are removed. Gross occlusal reduction and contouring is achieved via a fluted composite finishing bur.

 Enhance® Finishing cups, discs, or points are used for final contouring and finishing.

The restoration on tooth No. 4-DO. Note the excellent color blending, contour, and interproximal contact.
