Prevalence of crossbite among children with prolonged dummy- and finger-sucking habit.
The prevalence of crossbite was determined among 252 children with prolonged finger-sucking habit and 31 children with prolonged dummy-sucking habit. The prevalence of crossbite in both groups was within the values regarded in the literature as normal for the age group. An analysis was also made of 289 patients registered for orthodontic treatment. An elevated prevalence of crossbite was not recorded, either, among children with dummy- or finger-sucking habit in this group of patients.
