Scoring of Enamel Hypoplasia (EH) Extent for Primary Maxillary Central Incisors

EH extent score = sum of scores for EH by tooth regions

EH extent scores grouped for EH=0, EH=1, EH>1

Example using image of teeth 51 and 61:

51: cervical EH =0, middle EH=1, incisal EH=1

61: cervical EH =0, middle EH=1, incisal EH=1

EH extent score = 4; EH>1
