Influence of socioeconomic status on XXXX prevalence in schoolchildren.

@entity1 @entity5773 @entity29021 @entity5932 @entity10212
The aim of this survey was to determine the prevalence of @entity5932 in @entity1 aged 4-13 yr from two schools, one (S1) having a higher socioeconomic status than the other (S2). In all, 846 @entity1 were examined, 463 from S1 and 383 from S2, of whom 555 were @entity1 and 291 were @entity1 . There were 359 @entity1 and 104 @entity1 in S1; 196 @entity1 and 187 @entity1 in S2. Fifteen different lesion types were discerned. The most frequent ones were recurrent aphthous ulceration (RAU) (92 cases); fissured @entity10212 (54); herpes labialis (44); @entity10212 (30); @entity29021 (25); smooth tongue (22); and @entity5773 (17). An outstanding finding was the contrasting distribution of certain lesion types in the two schools. RAU was observed in 19% of the @entity1 from S1, making up 50% of all lesions detected. However, in S2 only 2% exhibited RAU, making up less than 4% of observed lesions. On the other hand, herpes labialis was seen in 1% of S1 and 10% of S2 @entity1 , regardless of age or sex. @entity5773 was found in 3.2% in S1 and 0.5% in S2; fissured @entity10212 in 2.9% in S1 and 12.8% in S2; and @entity10212 in 1.1% in S1 and 6.5% in S2. Therefore, there were no statistical differences between the schools in the ratio of total lesions observed to @entity1 examined, but a significant difference was apparent when individual lesions were taken into account.
