Abstract
The oral examinations conducted on the 6, 396 children of 3 primary schools, revealed that the incidence of cheilosis was observed in 641 individuals (10, 024%), in which male children always prevailed in number than female. Bacteriological cultures taken from the angle of the mouth showed the presence of following types of bacteria ; Staphylococcus (aureus, albus) Streptococcus (α, β, γ, ) Diplococcus (Gram, +, -, ) Bacillus (Gram, +, -, ) Blastomyces. Of these organisms, Staphylococcus aureus were cultured in 59.34% from the lesions which failed to appear in the case of normal mouths examined. In view of these findings, Staphylococcus aureus should be recognized most significant as the causative organisms of the lesion.
