Table 3.

Indications and limitations for restorations and mucogingival surgeries for DHS treatment

Indications for replacement of lost dentinal volume with restorations:

○ Hard tissue defect is visible and requires restoration for esthetics and structural integrity

○ Failure to resolve DHS using non-restorative treatment

○ High risk for continued dental tissue loss if not covered with restoration (e.g. inability to halt erosive or abrasive tooth wear)

○ Little or no removal of tooth structure is required for restoration

Indications for mucogingival surgery

○ Failure to resolve DHS using densensitization in patients with gingival recession

○ Gingival recession is esthetically unacceptable to patient

Risks or limitations for dental restoration and mucogingival surgery

○ General impermanence of restorations - the re-restoration cycle

○ Specific impermanence of resin-dentin bonding

○ Increased risk of caries lesion at the site of restoration

○ Questionable long term outcome of mucogingival surgery
