A survey of the records of dental treatment of 846 children and adults resident in a hospital for the mentally retarded was made to determine the proportions of mongoloid and non‐mongoloid subjects who had experienced necrotizing ulcerative gingivitis. The records covered a period of 10 years for long‐term residents and from the time of admission for those who were resident for less than 10 years. Eight hundred and six subjects had natural teeth present during some or all of the period of study. Thirty‐five percent of mongoloids had experienced one or more episodes of necrotizing ulcerative gingivitis, compared with 4% of non‐mongoloids (x 2 = 130·95, P<.001). Of those subjects who had experienced the condition. 49·1 % of mongoloids and 26·9 % of non‐mongoloids had recurrences. Episodes of necrotizing ulcerative gingivitis were associated with rapid progression of periodontal disease in mongoloids. The mean ages at the time of the first episode were 9·4 years for mongoloids and 9·9 years for non‐mongoloids.
