Purpose: The purpose of this study was to analyse the connection between dental arch widths, malocclusion type, nutritive sucking habits and non-nutritive sucking habits, and respiratory factors with the presence of crossbites (CB) in the early mixed dentition.
Materials and Methods: Data were collected from 72 children with and without CB. A questionnaire was applied to parents/carers to obtain information about nutritive and non-nutritive sucking habits. The posterior and anterior crossbites were diagnosed in a centric relationship. Dental arch widths were measured directly from the models by two calibrated examiners. The data were analysed statistically using chi-square and Fisher's exact tests.
Results: The incidence of Class III malocclusion and the presence of ear, nose and throat problems in the study group were significantly higher than in the control subjects (p = 0.01, p = 0.047). The mean breastfeeding duration for children in the CB group was found significantly shorter than in the control subjects (p = 0.043). The number of children with mouth breathing in sleep was significantly higher in the CB group than the control subjects (p = 0.046). The children with CB demonstrated a statistically significant increase in mandibular intercanine width (ICW) than the control group (p = 0.044).
Conclusion: The results demonstrated that an insufficient duration of breastfeeding, mouth breathing, ear-nose-throat problems and Class III malocclusion were associated with the presence of CB in the early mixed dentition.
