Minimal intervention dentistry: part 5. Ultra-conservative approach to the treatment of erosive and abrasive lesions.

The therapeutic management of tooth wear lesions does not require the removal of diseased tissue. Nevertheless, diverse etiological factors may be associated with the condition and they could be difficult to eliminate; this has to be considered when planning therapy. Interceptive procedures should be reserved for such situations while regular monitoring is recommended for other cases, in accordance with advice provided for using the Basic Erosive Wear Examination (BEWE). Direct and indirect adhesive procedures with composite resins allow treatment of most clinical situations, including even extensive restorations. The possibility of managing subsequent interventions should be considered when planning the initial therapeutic approach.
