Scores in the histologic analysis of calcific barriers and dental pulp.

Characterization		Score
A. Calcific barrier continuity
	Complete calcific barrier formation	1
	Partial/incomplete calcific barrier formation extending to more than half of the exposure site but not completely closing it	2
	Initial calcific barrier formation extending to no more than half of the exposure site	3
	No hard tissue deposition	4
B. Calcific barrier morphology
	Dentin or dentin-like irregular hard tissue	1
	Only irregular hard tissue deposition	2
	Only a thin layer of hard tissue deposition	3
	No hard tissue deposition	4
C. Tubules in calcific barrier
	No tubules present	1
	Mild (tubules present in <30% of the calcific barrier)	2
	Moderate to severe (tubules present in >30% of the calcific barrier)	3
	No hard tissue deposition	4
D. Pulpal inflammation severity
	Absent or very few inflammatory cells	1
	Mild (typically <10 inflammatory cells)	2
	Moderate (typically 10–25 inflammatory cells)	3
	Severe (typically >25 inflammatory cells)	4
E. Pulpal inflammation extent
	No inflammation	1
	Mild (inflammatory cells only next to the dentin bridge or the area of pulp exposure)	2
	Moderate (inflammatory cells observed in at least one-third of the coronal or mid pulp)	3
	Severe (all the coronal pulp is infiltrated or necrotic)	4
F. Pulpal inflammation type
	No inflammation	1
	Chronic inflammation	2
	Acute and chronic inflammation	3
	Acute inflammation	4
G. Dental pulp congestion
	No congestion	1
	Mild (enlarged blood vessels only next to the dentin bridge or exposed pulp area)	2
	Moderate (enlarged blood vessels observed in at least one-third of the coronal or mid pulp)	3
	Severe (all the coronal pulp is infiltrated with blood cells)	4
H. Odontoblastic cell layer
	Complete palisading cell pattern	1
	Partial/incomplete palisading cell pattern	2
	Presence of odontoblast-like cells only	3
	Absent	4
