ABSTRACT
Objective. The aim of this study was to evaluate tooth loss prevalence, denture types and prosthetic dental treatment needs among people of ages 35-44 of Bayangol District of Ulaanbaatar City. Materials and Methods 9351 subjects were examined and questionnaires were presented to partially and/ or totally edentulous subjects among patients of this research. The questionnaire consisted of questions; age, gender, education level, place of residence, problems with dentures, necessity for new denture. Results. Most of the people were partially edentulous (93.0%) and 6.0% was full dentate, 1.0% was complete edentulous. In this research, only 6% of the people are full dentate but 94.3% have missing teeth and it indicates that the most of the people are demanding partial denture treatment. Acrilic denture was consumed in (3159) 95.0% of total dental coverage, but only 116 people had fixed denture. Acrylic denture was consumed much more than removable partial denture and bridge, and it may be due to expensive price of bridge and implant. The number of female patients with complete dentures was more than the number of males, with opposing trend for partial dentures. Tooth loss is a major indicator of oral health among adults, which may be increased by the lack of access to care, certain chronic diseases and/or insurance status. Conclusions. Almost 940 people in each 1000 people of ages 35-44 or 9 of every 10 subjects of among patients of Bayangol District, Ulaanbaatar City have edentulism /р>0.001/. It has been estimated that 34.5% about adults of those with edentulism had prosthetic treatment and majority (95%) of them use acrylic denture. We can see that 94.3% of subjects among the patients of ages 35-44 in our research have had missing teeth and 60% of them had no any treatment and are demanding prosthetic treatment.
ABSTRACT
Background Concentrations of lead, chromium, cadmium, mercury, arsenic and boron in waste water treatment sample and soil sample of Mich Company in Khongor, Darkhan-Uul province were detected with high concentration by WHO, UNEP and FAO study in 1998. Therefore, the conclusion was required to conduct environmental audit and to determine pollution frame and risks [1, 2]. According to recommendation of WHO, UNEP and FAO study, it is required to conduct re-survey study of environ¬mental pollution in Khongor, Darkhan-Uul province. Goal Study was aimed to conduct re-survey study of environmental pollution and human health exposure assessment in Khongor, Darkhan-Uul province. Objectives: 1. To determine environmental pollution by questionnaire study and chemical analysis for mercury, chromium, arsenic, lead, cadmium and boron in hair, blood, urine and environment. 2. To develop guidance for next actions. Results Average concentration of arsenic in soil sample of Mich Co, Ltd was 8.458 mg/kg or 1.4 fold higher (95%CI 5.472- 11.444) than reference value (6.0 mg/kg) in “MNS 5850:2008 -Soil quality. Reference value for soil pollutants and elements” standard and mercury and cadmium were not detected (Table 1). Chromium and boron were detected with acceptable level in water samples and average concentration of arsenic (0.0014 mg/l) was lower than reference value (0.01mg/l) in “MNS 900:2005 Drinking water, Hygiene requirements and control” standard. This result shows that there was not arsenic migration from soil to water. Concentrations of lead, cadmium, chromium, arsenic, boron and mercury in soil and water samples were detected with acceptable level (Table 1). Conclusions: 1. Lead, mercury, cadmium, chromium and boron levels in environmental samples of Khongor, Darkhan-Uul province were at subordinate level from reference values in national standards. 2. Arsenic concentrations in biological samples were determined as a higher level, but in environmental samples its amounts were corresponded with acceptable level. Thus there was not environmental pollution exposure to human health. Because of detoxication processes of contaminated moulds by mercury and cyanides in MICH company area, it is possible to this area polluted by arsenic or gold associated elements. Thus it is necessary to decrease arsenic pollution in soil. 3. Concentrations of cadmium, arsenic, lead and mercury in hair, urine and blood samples were less than refer¬ence value of Human biomonitoring commission of Germany (HBM), PHI of USA, Clinical chemist’s agency of Russia and Canadian medical research center. So, in Khongor soum had not those of toxic elements ex¬posure to human health. 4. The boron and chromium concentrations of hair, urine and blood samples exceeded the maximum admissible limits in half of all cases, while their amounts in environmental samples were at permissible level according to national standards. And there was no statistical significance correlation (p=0.735) between chromium and boron concentrations in biological and environmental samples.
ABSTRACT
PIP: This study describes differences in infant and child mortality in Mongolia and examines the main possible determinants of mortality. The policy implications are discussed. Data were obtained from the 1994 Demographic Survey of Mongolia among 2030 women and 1026 men aged 15-49 years and 4685 children. Analysis was limited by the small sample size and the unavailability of data on access to health services and nutrition. Birth history data revealed 25.9% of births in the capital city, 24% in provincial capitals, and 50.1% in rural areas. The sex ratio was 100 females to 102 males. Rural mothers were less educated. Fertility was 4 children/woman in rural areas, 3.4 children/woman in provincial capitals, and 2.8 children/woman in the capital city. Over 60% of mothers were unemployed, and 76.5% of mothers were unemployed in rural areas. Rural mothers received lower salaries. About 50% had electricity in their homes. Almost 95% of the rural population lived in single rooms, portable tents made of felt. 31.3% lived in tents in the capital city. Hot and cold running water was available to 50% in the central city and to 19.1% in provincial capitals. Higher socioeconomic status was associated with lower infant and child mortality. There was a wide range in mortality levels by maternal salary. Infant and child mortality was lower in households that had consumer goods. The number of cows owned by the household was unrelated to child survival. 90% of Mongolian women were literate. The educational status of the mother had the strongest and most significant effect on the level of infant and child mortality. The level of infant and child mortality was still too high for all educational groups. Mortality was high for infants and children living in tents. Findings suggest that early-age mortality in Mongolia is not consistent with the level of social development. Access to health care and quality of health care may be key reasons for this disparity.^ieng
