using a soft bristled hand toothbrush. In-vitro research has shown that there is a higher potential for abrasion on erosive enamel & dentine with an electric toothbrush as compared to a manual toothbrush. Furthermore, delay brushing of teeth until approximately an hour after an acidic meal to prevent the removal of softened tooth substance. Use products that promote remineralisation such as fluoride-containing mouthrinses and toothpastes. Fluoride-containing products promote repair of acid damaged tooth surfaces and block exposed dentine tubules, reducing dentine permeability and preventing hypersensitivity. When used before contact with acid, fluoride-containing products also help inhibit acid erosion. Stannous fluoride (SnF2)-containing toothpastes in particular have been shown to increase resistance to acid erosion compared to other fluoride-containing toothpastes. B: Dental professionals To facilitate detection and diagnosis, dental professionals should be aware of the appearance of tooth erosion – short, cupped, saucer-shaped with a glassy, shiny surface and loss of surface architecture. Several teeth are affected at the same time, with the most commonly affected area being the tongue surfaces of the upper front teeth. Recording index. Use the Basic Erosive Wear Examination (BEWE), an objective four-level scoring system to determine the severity of erosion in each sextant. The cumulative score corresponds to its level of risk and acts as a guide for appropriate management. The distribution of BEWE scores is said to be more accurate than that of Tooth wear index (TWI) scores. 0 = no erosive tooth wear 1 = initial loss of surface texture 2 = distinct defect, hard tissue loss < 50% of surface area 3 = hard tissue loss ≥ 50% of surface area Minimal intervention & prevention of dental erosion. The first line treatment after detection of acid erosion is remineralisation and prevention. Remineralisation is the reparative process of demineralised tooth substance. It is commonly promoted by applying fluoride-containing substances onto the surfaces of affected teeth, though is limited by bioavailable calcium. The following are some methods of remineralisation: professionally-applied fluoride varnish, home-applied fluoride gel and toothpaste with stannous fluoride (SnF2) formulation. Prevention of erosion is largely through discussions regarding avoidance/management of extrinsic and intrinsic sources of acid, and recommendation of suitable at-home preventive oral hygiene habits. Correct tooth brushing technique (timing, bristle stiffness, brushing force & toothpaste) should be discussed. Toothpastes containing stabilized stannous fluoride have higher anti-erosive properties when compared to conventional sodium fluoride or sodium monofluorophosphate formulations. Where possible, a stabilized stannous
