The Scottish Dental Show 2018 keynote speaker Monik Vasant presents a posterior restoration case in a patient found to have caries under an existing amalgam filling

A new patient in her early 30s attended for a check-up. A routine radiograph revealed caries under the amalgam filling on the upper right second premolar (UR5). When advised the tooth needed treatment, the patient revealed she had been unhappy with how it looked. The filling was very visible and shiny when she smiled. The dark appearance of the tooth also made her self-conscious. The patient had thought treatment would be long and expensive, so she hadn’t bothered to ask.

The options were to have another amalgam filling or a composite restoration. The patient was advised that further composite treatment could be needed buccally to mask any remaining grey discolouration, if she was not satisfied with the outcome. As she was concerned about the appearance of the tooth, the patient did not want an amalgam filling and decided to have the composite restoration.



After a local anaesthetic was given, rubber dam was placed, with a clamp on the UR6, exposing the UR 4, 5 and 6. This was secured in place with floss ties. The old amalgam and caries were removed. The final portion of discoloured dentine was left behind as it was very deep, but the pulp was not exposed and it was still firm.

A sectional matrix band was then positioned mesially on the UR5, with a wedge and separation ring (V-ring). Initially, the enamel periphery alone was etched with 37 per cent phosphoric acid for 15 seconds. Etch was applied to the rest of the cavity for a further 15 seconds, before rinsing. A cotton pledget was used to protect the dentine during the drying process, to ensure dry enamel and moist dentine.

A two-bottle adhesive, with separate primer and adhesive, was used to complete the preparation. The dentine was primed and left for 30 seconds. The adhesive was placed on both the enamel and dentine, and allowed to sit for
30 seconds before curing.



In this case, Venus Pearl composite was used. This material exhibits good levels of opacity to block out discolouration and excellent handling for posteriors, making it a very easy-to-use product.

In this restoration, a small amount of Venus Flow base liner was placed and cured. This was to mask the greyness and dark discolouration from the base of the cavity. Next a thin layer of Venus Pearl A2 shade was applied to build up the mesial wall against the matrix. The height was built up to the level of the adjacent marginal ridge. The material was then manipulated with a sharp probe at a 45 degree angle. This ensured the edge of the wall was not straight and the natural curved shape of the marginal ridge was maintained. The dentine mass was built up in increments with Venus Pearl ODC shade.

Enamel A2 shade was placed over the occlusal surfaces cusp by cusp. Complete separation of the masses was achieved by creating fissures down to the dentine layer, using a sharp probe. Secondary anatomy was manipulated into the unset material before light curing.

A mix of Venus Color ‘corn’ and ‘choco’ stains was applied to the fissures using a probe, and pressed in with a long- bristle brush. The excess was wiped away with a conventional micro-brush and the stain was cured. Highlights were placed on the ridges using Venus Color ‘white’ mixed with a little ‘corn’, to give a milky colour. Final adjustments were carried out before rough, dry polishing. The restoration was then sealed with a protective clear coating, covered with glycerine and cured.



In this case, the clinical outcome was good. The tooth is regularly monitored for vitality and the patient has had no problems with it. As the caries was so deep, in the long term the tooth may require root canal treatment, but it is currently sound. The patient was delighted with the result after having endured an unsightly amalgam filling for years.
