Tooth, surface and hierarchy codes for examiner determinations of clinical conditions

Group	Code	Clinical Condition
Tooth Status Codes	P	Present (but not a tooth status below)
	R	Partially Erupted
	K	Sound (all surfaces)
	U	Unerupted
	M	Missing due to caries
	T	Missing due to trauma
	X	Missing due to exfoliation

Tooth Surface Status Codes	K	Sound
	D	Cavitated decayed (d₂₊) lesion
	W	Demineralized (white spot or d₁) lesion
	A	Filled surface - amalgam
	F	Filled surface - non-amalgam
	S	Sealed surface
	U	Unerupted surface
	Z	Unable to score

Precedence Hierarchy	D > A, F, W, S	Cavitated lesion takes precedence over any filled lesion, white spot lesion, or sealant
	A > F, W, S	Amalgam filling takes precedence over non-amalgam filling, white spot lesion, or sealant
	F > W, S	Non-amalgam filling takes precedence over white spot lesion, or sealant
	W > K, S	White spot lesion takes precedence over sound surface or sealant
