In primary dentition, the probing depth of the sulcus is approximately how many millimeters?

Probing depth measures from the free gingival margin to the base of the sulcus. In healthy primary dentition, the gingival sulcus is about 2 millimeters deep. This reflects a shallow, healthy sulcus typical for children’s gums. A depth around 2 mm is normal, whereas readings of about 3 or 4 mm would suggest a pocket or inflammation, not normal health. A 1 mm reading is unusually shallow and less typical for a healthy primary sulcus.
