130 mins CPD/CE

Aims and objectives:

  • Understand natural light characteristics and the role of scattering
  • Selective enamel dissolution to understand the shape and morphology of dentine
  • How scattering affects optical properties of restorative materials and also how material properties can be altered to influence scattering, and material optical properties
  • Understand the role of opalescence
  • The refractive index concept and how the material and its various components would alter this and cause scattering
  • Understand opacity in the role of light, and the role of opacity in dentine and enamel
  • How these characteristics led to the development of Essentia and the essential characteristics
  • Understand this for junior, adolescent, adult and senior enamel and dentine
  • A shade selection strategy including the influence of dehydration, ageing and other factors
  • Direct shade taking strategies, and indirect shade taking strategies
  • The E Lab protocol and understanding colour perception, and how this works in indirect shade taking
