Occlusal tissue loss from erosive aetiology can also be of strikingly different shape either presenting as deeply hollowed out lesions (a subject with raw food diet [15], b subject with excessive consumption of orange juice) or as amorphous generalised tissue loss affecting the entire surface (c, d subjects with excessive consumption of erosive drinks). An interesting feature is seen in an adolescent with a history of severe anterior open bite with only the molars being in function e Substance loss occurred from excessive consumption of a cola type drink. In the premolars, dentine is proud of the surface. f Hollowing out the entire occlusal surface with enamel remnants in the centre, aetiology is the excessive consumption of sport drinks
