A tooth the resolver refuses to guess at is currently a dead end: the sheet
says the quadrant was missing and the clinician has to leave and find the
tooth on the chart. But the readings are enumerable — "دو" is one of four
teeth, "دو بالا" one of two — so unresolved items now carry them.
Narrowed by whatever was actually said, so this stays a choice offered to
the clinician rather than a guess made for them. Only tooth_missing_quadrant
carries candidates; a wrong position or a deciduous tooth has nothing to
choose between.
