Abstract


Aim. To assess the attributable risk of dentoalveolar and facial anomalies prevalence among children depending on the features of family history.

Methods. A sample of 2000 children was selected (250 boys and 250 girls from 4 age groups: 3-5, 6-9, 10-12 and 13-15 years). Characteristics of the family history was obtained by parents’ survey. The risk of dentoalveolar and facial anomalies was determined by comparing their frequency between groups with compromised and normal family history. Attributable risk was defined as the difference in the frequency of dentoalveolar and facial anomalies.

Results. The number of teeth with abnormal position per 100 examined patients ranged widely: from 72.3±1.1 to 105.4±5.3. Depending on various characteristics of the family history, the attributable risk of anomalous tooth position varied in the range from 3.0 to 33.1 per 100 children. The highest attributable risk of anomalies of the tooth position in children was revealed in cases when their parents had a history of dentoalveolar and facial anomalies (33.1%). In the presence of close relatives’ history of dentoalveolar and facial anomalies (except grandparents) attributable risk of anomalies of the tooth position in children was 11.4-14.8%. In the groups of children, whose grandparents had a history of dentoalveolar and facial anomalies, the prevalence of anomalies of the tooth position (80.9±2.0 per 100 children) was not significantly different from that in the control group (77.9±1.0). It can be explained by the fact that during the parents’ survey they were not able to state with certainty grandparents’ history of dentoalveolar and facial anomalies.

Conclusion. Compromised family history in children is associated with high attributable risk of anomalies of occlusion and tooth position.
