In a group of 6-12-year-old children from a Prague primary school the authors investigated the standard of oral hygiene, using the OHI-S plaque index, DMF of the first permanent molars and the attitude of the family to personal hygiene of the children, using care of the finger nails as a criterium. Poor finger nail care was recorded on average in 27%. Poor finger nail care was not directly related to the standard of oral hygiene and the cariosity of the permanent molars. The author explains this findings by the regular influence of dental surgeons on the children's attitude to dental care.
