Impact of modifiable risk factors on the severity of dentofacial abnormalities

Relevance. In children aged 6–9 years, the most common modifiable risk factors for dentofacial abnormalities were premature loss of primary molars and altered anatomical form of the primary molars, both of which contribute to the development of deep bite and Class II malocclusion. In combination with delayed attrition of the primary canines, these factors significantly influence the development and severity of dentofacial abnormalities. Timely correction of these modifiable factors through preventive interventions is essential for reducing the risk and severity of dentofacial abnormalities.

Materials and methods. A retrospective analysis was conducted of the dental records of 245 children aged 6–9 years who presented for treatment to a pediatric dentist. The study recorded the frequencies of premature loss of primary molars, altered anatomical form of primary molars, and delayed attrition of the primary canines as risk factors for dentofacial abnormalities. Interarch relationships were assessed, and the severity of dentofacial abnormalities was evaluated.

Results. Retrospective analysis of the dental records showed that, among children aged 6–9 years, altered anatomical form of the primary molars in combination with Class II malocclusion and deep bite was the most common finding, observed in 54.2% of cases.

Conclusion. Altered anatomical form of the primary molars contributes to the development of Class II malocclusion and deep bite and is associated with greater severity of dentofacial abnormalities.
