[Prevalence of dental anomalies and need for orthodontic treatment among adults in the Arctic part of the Arkhangelsk region].

Abstract

Objective: The aim of the study is to study the prevalence of dental anomalies (DA) and assess the need for orthodontic treatment (NOT) among adults in the Arctic part of the Arkhangelsk region.

Materials and methods: In total, 1068 adult residents of Arkhangelsk and Primorski rural district aged 35-90 years took part in a cross-sectional study. The Dental Aesthetic Index (DAI) was used to assess the prevalence of DA and NOT in the study population. The prevalence is presented as percentage with 95% confidence intervals (CI) calculated using Wilson's method.

Results: The overall prevalence of DA was 55.2% (95% CI: 52.2-58.1). It was found that 58.2% (95% CI: 53.5-62.8) of men and 53.1% (95% CI: 49.2-56.9) of women required orthodontic treatment. The highest prevalence of malocclusion and the need for orthodontic treatment was identified in the age group of 60-74 years in both men and women. This high rate is due to removed teeth, periodontaland somatic diseases so that ortodontical treatment should be used to improve quality of life.

Conclusions: The prevalence of dental anomalies and the need for orthodontic treatment in the adult population of the Arctic zone of the Arkhangelsk region is at a high level. Improving dental literacy and developing strategies directed at early prevention of dental diseases starting from childhood, particularly in remote areas, is warranted.
