The Gingival Index by Loe and Sillness (1963) is widely being used in epidemiological studies to assess the Gingival health. The modified scale assesses 6 index teeth in the permanent dentition to score gingival health. My question is that we use Gingival Index for a child in mixed dentition or primary dentition, what index teeth should we use?
Any studies published with modifications for primary teeth?
