Managing erosion, poor oral hygiene and exposed roots Prof. Matteo Basso A 78-year-old lady presented for treatment with evidence of erosion combined with mechanical abrasions from normal masticatory function. Gold overlays which were placed 35 years ago (4 in each quadrant on premolars and molars) continue to function effectively. GC Tri Plaque ID Gel was used to identify areas where the plaque has not been cleaned off. The areas that appear light blue are of most concern, as this is where an acid-producing cariogenic biofilm has developed (image 3). Cervical lesions were restored with EQUIA® Forte as the shape of those lesions facilitated plaque deposit. MI Varnish™ was applied to reinforce thin enamel layers and to protect the margins of the overlays. MI Varnish™ will be reapplied at every recall appointment to help elevate calcium, phosphate and fluoride levels at and around high risk sites. 1. Enamel erosion. 2. GC Tri Plaque ID Gel applied. 3. Areas that are light blue indicate a high risk biofilm. 4. CAVITY CONDITIONER was used (10 sec.). 5. EQUIA® Forte Fil (A3) was placed. 6. Finished restoration. A recent study showed that "a single-application of fluoride topical varnishes was effective in reducing enamel wear." MI Varnish™ "had the best effect against enamel loss from an erosion-abrasion challenge."* 7. MI Varnish™ was applied to reinforce thin enamel layers. 8. MI Varnish™ was applied to protect the margins of the overlays. *Alexandria AK et al. (2017). In vitro enamel erosion and abrasion-inhibiting effect of different fluoride varnishes.
