[Periodontol problems in the mixed dentition]

The authors studied the periodontal and oral hygiene conditions in 343 children from the children's town of Fót. They observed a not too great increase in gingivitis intensity in the mixed dentition which is very seldom seen under physiological conditions of the change to permanent dentition; but which occurs frequently in individuals with badly decayed milk molars associated with poor oral hygiene and impaired masticatory function.
