Oral hygeine status of children with henoch-schonlein purpura (HSP) disease Backround: Henoch-Schonlein Purpura (HSP) disease is an inflammatory disease in which capillaries, venules, and arterioles are dominated by microvessels due to the accumulation of Ig-A immunity in the walls. Eighty percent of children with HSP have chronic infections such as chronic tonsillitis, otitis media, dental caries, and gingivitis.1-8 However, no research has yet been conducted to determine the prevalence and severity of tooth decay in children with Shenlein-Genoch disease, and to assess gingivitis and oral hygiene. Materials and methods: The survey was conducted from 50 children with the HSP from the Department of Cardiovascular Connective Tissue Pathology of Pediatric Consultant Polyclinic of the National Center for Maternal and Child Health and was conducted in using cross-sectional survey accordance with the number 07- 2021/3, Principles of the Research Ethics Review Committee of the Mongolian National University of Medical Sciences and, the results of the study were processed using the statistical software SPSS 25. Results: The prevalence of tooth decay among children with HSP was high at 95% for mixed dentition and 100% for each stage of primary and permanent dentition, while the intensity of tooth decay was 7,304.64 (caries+ fillings+extraction/ tooth) during primary dentition, 7,303.46 (caries+fillings / tooth) + (caries+fillings+extaction / tooth) during mixed dentures and 11,294.13 (caries+fillings+extraction / tooth) during permanent dentition. It is noteworthy that the level is very high at all.In the study of children with gingivitis, 50% of them had gingivitis with primary dentition, 60.9% with mixed dentition, and 58.8% with permanent dentition. The proportion of healthy children without gingivitis was 50% for primary dentition, 39.1% for mixed dentition, and 41.2% for permanent dentition. The proportion of “good” condition in the study was 30% for primary dentition, 39.1% for mixed dentition, 35.3% for permanent dentition. The “mean” rate was highest for 70% for primary dentition, 56.5% for mixed dentition and 58.8% for permanent dentition. The “insufficient” rate was 4.3% for mixed dentition and the lowest for 5.9% for permanent dentition. Conclusions: 1. The prevalence of tooth decay among children with HSP was high at 95% for mixed dentition and 100% for each stage of primary and permanent dentition, while the intensity of tooth decay was 7,304.64 (caries+ fillings+extraction/ tooth) during primary dentition. 7.303.46 (caries+ fillings+extraction/ tooth)+ ( caries+ fillings+extraction/ tooth) during mixed dentition and 11.294.13 (caries+ fillings+extraction/ tooth) for permanent dentition means that all of the level is at high intensity. 2. In the study of children with gingivitis, 50% of them had gingivitis with primary teeth, 60.9% with mixed teeth, and 58.8% with permanent teeth. The proportion of healthy children without gingivitis was 50% for primary dentition, 39.1% for mixed dentition, and 41.2% for permanent dentition. However, there is a statistically significant result (p <0.001) of the more increase in tooth plaque of poor oral hygiene the more increase in gingivitis. 3. The proportion of “good” condition in the study was 30% for primary dentition, 39.1% for mixed dentition, 35.3% for permanent dentition, the “mean” rate was 70% for primary dentition, 56.5% for mixed dentition and 58.8% for permanent dentition. The “insufficient” rate was 4.4% for mixed dentition, or the lowest for 5.9% for permanent dentition. There were no statistically significant differences (p> 0.05) between oral health and the HSP status of the children in the study. According to the results of the survey, it is observed that the oral health status among the respondents is insufficient.

The prevalence and type of congenital cleft of the lip and palate in mongolia, affiliation of the patients Background: The prevalence of congenital cleft lip and palate is different internationally. There are some research papers which identifying the rate of this abnormality in Mongolia, the latest one shown the result that one cleft case for 1072 live births (Ayanga GN et all, 2012). Aim: to determine/update the prevalence and types of congenital cleft lip and palate in Mongolia Materials and methods: we include the data from all cleft patients who were born between 01 of January, 2011-31 of December, 2021 to this survey retrospectively. We used the e-history for cleft patients, which developed by the department of Maxillofacial surgery since 2011. Results: Totally 1308 cleft patients included to our survey. The prevalence is one cleft cases for 652 live births in Mongolia, and 34,1% is cleft of the lip, 41,4% is cleft of the lip and palate, and 24,5% is cleft palate only of all cases. Also the rate was differently among provinces, as one for 429 live births in Khuvsgul province, and one for 1223 live births in Uvs province. Conclusions: the prevalence of cleft lip and palate in Mongolia 1000:1.5 or one for 652 live births. The highest rate established in Khuvsgul province, and the lowest in Uvs province.
