Background: According to the results of the research conducted in Mongolia in 2011 within the framework of the national program "Oral Health", 86.2% of young children had tooth decay, and the intensity of tooth decay was 6.2, which is a high level. In recent years, not only in our country, but also in the world, due to the increase in the prevalence of tooth decay in young children, the disease of other organ systems caused by tooth decay has also increased, which is the basis of our research. Purpose: To study the intensity of dental caries among secondary school students and comparing them with some indicators Objective:
1. To estimate the intensity of dental caries among secondary school students
2. To study the intensity of dental caries among secondary school students by comparing some parameters. Methodology: A total of 1298 students aged 6-18 years of Bayanzurkh Complex School of the capital were included in the study. Determine the body mass index ,The Lith the lip method was used to calculate the intensity of dental caries and it was assessed by the World Health Result: 675(52%) of the respondents were male and 623(48%) were female, 7.6% were underweight, 68% were normal weight, 14.7% were overweight, and 9.7% were obese.
When examining the state of dental disease of the participants, 9% were healthy, 91% had dental disease, the intensity of caries was 4.9 CSI, and the need for rehabilitation was 319. Out of this, in children with permanent teeth, the intensity of caries in great molars and in children with mixed teeth is higher in second molars. Conclusion The intensity of dental caries is 4.9 cla/sh or more, and the prevalence is high, and there are 319 children who need to be treated immediately.
The intensity of dental caries was medium for 6-13 year olds and low for 14-19 year olds, and the caries intensity of normal weight children was 3.3 or medium.
