LESIONS AND ABFRACTIONS

I enjoyed the article, "Non-Carious Cervical Lesions and Abfractions: A Re-Evaluation" by Dr. Luis A. Litonjua and colleagues (July JADA), which nicely summarizes a great deal of information about this important topic.

Additionally, I would have liked to see the following questions discussed in the article:

  1. Where is the point of initiation of the typical lesion? My impression is that it is generally below the cementoenamel junction.
  2. Is the typical lesion confined to dentin? I know that enamel-only lesions do exist, but they are comparatively rare.
  3. How common are subgingival lesions? Again, I know they exist, but they are quite rare, so it appears that gingival recession and root exposure are necessary for lesion formation in most cases.

I believe that answering these questions will help elucidate the etiology of these lesions and suggest preventive strategies.
