pH: a factor in periodontal disease in the mongoloid
Phillips, William A.
MetadataShow full item record
The plaque pH values determined by the labial plaque of the six mandibular anterior teeth, and the salivary pH values were examined in vivo in seventy-five children made up of four distinct groups. Group I consisted of institutionalized mongoloids, group II consisted of home-bound mongoloids, group III was composed of institutionalized non-mongoloid mental retardates, and group IV consisted of home-bound normal children. The results were statistically evaluated with several variables including age and sex. Analysis of the data revealed a significant difference in the plaque pH values between the four groups; group I showing an average plaque pH of 6. 95, group l I 6.55, group III 6.66, and group IV 6.60. There was also a significant difference in the periodontal condition of the 30 four groups (Dufour ). The institutionalized and homebound mongoloids exhibited not only a higher or more alkaline plaque and salivary pH, but also a more severe periodontal condition. There was no significant difference when plaque and salivary pH values were compared to age and sex.
