DIAGNOSIS of Noncarious Cervical Lesions

By Dr.Swathi Pai on Wednesday 16 April 2008 with 0 comments



Abrasion

  • Mechanical wear produced by the friction of exogenous material

  • Smooth, concave lesions with no sharp internal line angles

  • U-, or wedge-shaped ditch on the facial root surface in proximity to the CEJ

  • Oral-hygiene-related abrasions are usually concomitant with gingival lesions such as laceration,hyperplasia and gingival recession, the latter being the most common

  • The gingival sulcus is usually shallow in proximity to abrasion lesions

Attrition

  • Incisal or occlusal wear resulting from tooth-to-tooth contact through functional or parafunctionalmovements

  • Does not usually pertain to cervical lesions

Erosion

  • Loss of tooth structure from the action of dietary or gastric acids
  • May appear on facial and lingual surfaces
  • Usually involve a wide area of tooth destruction, with no sharp angles
  • Lingual surfaces - rule out bulimia or esophageal reflux
