Clinical Information
  • A change in tooth color. Causes may be local or systemic and include tobacco use, foods, dental plaques, caries, restorative filling materials, trauma, medications, infections, hereditary diseases, and nutritional deficiencies.
  • A disorder characterized by a change in tooth hue or tint.
  • Accumulations of microflora that lead to pathological plaque and calculus which cause periodontal diseases. It can be considered a type of biofilms. It is subtly distinguished from the protective dental pellicle.
  • Any change in the hue, color, or translucency of a tooth due to any cause. Restorative filling materials, drugs (both topical and systemic), pulpal necrosis, or hemorrhage may be responsible. (jablonski, dictionary of dentistry, 1992, p253)
  • Hard or soft material deposited on a tooth surface, such as dental calculus or plaque and materia alba.
