Material and methods
From the files of the Department of Pedodontics, Dental Policlinic, Kranj, Slovenia, 30 children with posterior crossbite (13 boys, 17 girls; mean age, 5.5 years; range, 3.6-7.2 years) and 30 children without crossbite (17 boys, 13 girls; mean age, 5.9 years; range, 5.4-6.7 years) were randomly selected from the local kindergarten and invited to participate in this study. The research was approved by the Ethics Committee, University of Ljubljana, Medical Faculty, Ljubljana, Slovenia, and the
Results
Comparisons of various parameters from the questionnaire regarding nutritive and nonnutritive sucking behaviors between the posterior crossbite and the noncrossbite groups of children showed no statistically significant differences for the durations of breast-feeding and bottle feeding (Table I). However, a statistically significant difference was found between the 2 groups in the duration of pacifier habit (P = 0.001, Table I).
The otolaryngologic findings (Table II) showed no statistically
Discussion
Preventive and early treatment with orthodontics is still the subject of continuous debate and controversy regarding cost-effectiveness, and functional and psychosocial benefits. Early treatment of posterior crossbite is advised to enhance skeletal and dental development and correct habits, improper functions, and malocclusions in their early stages, especially the transverse discrepancies that can cause TMJ problems or facial asymmetry.1

Conclusions
On the basis of our results, the following should be emphasized.
- 1.
To intercept the development of crossbites and functional shifts, parents and pediatricians should assess orofacial functions in young children with a history of prolonged pacifier and bottle feeding habits.
- 2.
Every clinical examination of a child with nonnutritive sucking habits should include assessments of the length of the frenulum linguae and the resulting tongue posture.

In this case, the maxilla displacement could indicate just an inverse growth pattern, i.e. a narrowed development, as it was already noted in some clinical studies [21,90]. Likewise, this result was consistent with the displacement patterns and with the narrowing of its transverse dimension reported in our 3D morphological analysis (shown in Fig. 8).
