  • defects
  • Extrinsic stains can become internalised through enamel defects or cracks or as a result of dentine becoming exposed but most extrinsic stains appear to be deposited on or in the dental pellicle. (wikipedia.org)
  • tooth surface
  • Significant decrease in local pH changes the chemical balance of the tooth surface and increases the solubility of hydroxyapatite [ 24 ]. (hindawi.com)
  • This invention provides an improved etchant gel which more precisely indicates to the dental practitioner when a consistent and optimal dissolution of tooth surface has been achieved, thereby avoiding failure of the procedure and damage to the tooth. (google.com)

  • susceptibility
  • Common oral problems associated with diabetes mellitus include xerostomia, increased susceptibility to infections, salivary dysfunction, and dental caries [ 8 , 26 , 27 ]. (hindawi.com)
  • density
  • Demineralized enamel specimens were imaged using a high-resolution micro-CT system and lesion parameters including mineral density and lesion depth were extracted from mineral density profiles. (hindawi.com)
