Independently of the origin of teeth absence loss, previously indicated extractions, or agenesis, five points were assigned in cases when only one or two teeth were missing, four points if three or four teeth were missing, and only three points in cases where there were five or more missing teeth.
Se asignaron cinco puntos si sólo faltan una o dos piezas en boca, cuatro puntos si son 3 ó 4 piezas, y sólo tres puntos si son 5 o más las piezas faltantes.
