Prediction of Malocclusion Development Based on the Evaluation of the Ethiologic Factors

Antanas Šidlauskas, Kristina Lopatiene


The increase in the number of malocclusion and the change in the goals of modern orthodontics resulted in the improvement of the prevention methods and the elimination of etiological factors of malocclusion in deciduous and early mixed dentition. The purpose of the study was to determine the most informative etiological criteria of the malocclusion development. 1463 7-15 year-old children in three randomly selected Kaunas city schools were examined . The study included interview of children , questionnaire-based interview of parents, and clinical examination. The study showed that the following malocclusions were most common among the studied 1463 7-15 year-old children: malposition of upper (40.3 %), and lower incisors (39.4 %). The analysis of occlusion showed that 21.1 % of children had increased overjet greater than 3.5 mm; distribution of the occlusal relationships of the first permanent molars according to Angle classification was the following: Class I – 69.2 % of subjects, Class II – 27.9 %, Class III – 1.6 % of children; open bite was found in 4 % of subjects, and posterior crossbite was detected in 9.5 % of children. Applying the method of the multivariation logistic regression, the following etiological factors causing development of malocclusion in the studied contingent were determined: mouth breathing, family history of malocclusion, prolonged sucking of a pacifier and adenoids. The multivariation logistic regression method enables to predict the probability of some malocclusion (malposition of upper incisors, increased overjet greater than 3.5 mm, malocclusal relationship of the first permanent molars according to Angle classification Class II, posterior crossbite) development according to the etiological criteria.

Key words: maloccusion, etiological factors, prediction.
