Final answer:
The distance between the bottom of the gingival sulcus and the alveolar crest in clinically normal periodontium is 0.5-1.0mm.
Step-by-step explanation:
In clinically normal periodontium, the distance between the bottom of the gingival sulcus and the alveolar crest is 1) 0.5-1.0mm.
The alveolar crest is the highest point of the bone that surrounds and supports the teeth. The gingival sulcus is the space between the gum tissue and the tooth. In a healthy periodontium, the distance between the bottom of the gingival sulcus and the alveolar crest is generally around 0.5-1.0mm.
