Oral manifestations vary markedly dependingon the specific EB type, the molecular defect, site of tissue separation and other factors.
– Keratin genes – KRT5, KRT14
– Laminin genes – LAMA3, LAMB3, LAMC2
– Type VII Collagen – COL7A1 (over 600 mutations)
Oral Soft Tissue Manifestations of EB
• Highly variable depending on EB type
– – – – – – Increased fragility Perioral lesions MicrostomiaUlceration of mucosa, lips, checks, tongue, palate Ankyloglosia Obliteration of oral vestibule
EB Associated Soft Tissue Manifestations
• Can markedly affect ability to care for teeth. • Can makeproviding oral health care extremely challenging.

Oral Soft TissueScreening
• Individuals with Recessive Dystrophic EB are at increased risk for oral carcinoma. • Self examination – monitor oral lesions for marked changes, especially lesions developing hard or rolledborders and increasing in size. • Professional oral examination every 6 months
