Abstract:
Background:The capital city of Mongolia, Ulaanbaatar is not only one of the coldest capitals in the world but has also
become one of the most polluted cities in recent years due to the prolonged effects of severe cold. According to the World
Health Organization (WHO), the most harmful air pollutant to human health is PM2.5. These fine particulate matters can
penetrate the human body through the respiratory tract, causing various changes in the body and the oral cavity.
Aim:Relationship between dental caries, gingivitis and periodontal status and PM2.5 air pollutant levels among 12 years
old children in different areas of Ulaanbaatar.
Materials and Methods:The study population consisted of 190 children aged 12 years old, who were selected from high
and low level areas with air pollutant PM2.5 in Ulaanbaatar city, Mongolia. We obtained informed consent No.24-25/10-1
of the Ethical Committee, MNUMS. The oral examination of every child was done according to WHO recommendation
(2013). We determined the prevalence of dental caries and mean DMFT score, and the prevalence of gingivitis, and CAL
score. Statistical analysis was done by the SPSS 29 software.
Results:The prevalence and mean DMF/t score of dental caries were 96% аnd 5.37±2.75 among children living in the
high level area of the PM2.5 air pollutant; and 91% and 5.39±3.95 in the low level area, respectively (p<0.01). The prevalence
of gingivitis was 23.2% among all children; 25.2% among children living in the high level area of the PM2.5 air
pollutant and 20.5% in the low level area. The CAL score was 1.89±0.89 mm in the high polluted area and 1.94±0.77 mm
in the low polluted area (p<0.001).
Conclusion:The prevalence of dental caries and gingivitis and the mean DMFT and CAL score among children living in
air polluted areas were higher than low polluted areas.
