RAE scoring system for OLP

Clinical signs	Scoring
Reticular lesions (R)	0 = no white striations
	1 = presence of white striations or keratotic papules
Atrophic areas (A)	0 = no lesion
	1 = lesions less than 1 cm2
	2 = lesions from 1 to 3 cm2
	3 = lesions greater than 3 cm2
Erosive areas (E)	0 = no lesion
	1 = lesions less than 1 cm2
	2 = lesions from 1 to 3 cm2
	3 = lesions greater than 3 cm2
The total score of all 10 areas	ΣR + Σ(A × 1.5) + Σ (E × 2.0)

The oral cavity of each individual was divided into 10 sites: upper/lower labial mucosa, right buccal mucosa, left buccal mucosa, dorsal tongue, ventral tongue, floor of mouth, hard palate mucosa, soft palate/tonsillar pillars, maxillary gingiva, mandibular gingiva.

Abbreviations: OLP, oral lichen planus; RAE, reticular, atrophic, erosive.
