Relationship between index of orthodontic treatment need dental health component (IOTN-DHC) and caries prevalence in school-age children.

Objectives: The objectives of the study were to investigate the relationship between caries prevalence and the Index of Orthodontic Treatment Need Dental Health Component (IOTN-DHC) in school-age children who live in the dentistless area and to consider the effective way to reduce the potential progression of malocclusion with the growth through the dental survey in Arbulag district, Khövsgöl province, Mongolia.

Materials And Methods: The 95 school-age children (49 males, 46 females) who participated in the study were born in and were residents of Arbulag district, Khövsgöl province, Mongolia. The mean ages of the participants were 8.

Association between Child Abuse and Poor Oral Habits in Mongolian Adolescents.

(1) This study aimed to investigate the association between child abuse and oral habits in adolescents in Mongolia. (2) A cross-sectional survey was conducted with children and their caregivers in Ulaanbaatar, Mongolia. Parents of 770 children enrolled in two public schools in Ulaanbaatar, Mongolia, completed questionnaires regarding the physical and psychological abuse that their children were subjected to and the presence of poor oral habits (biting nails/lips/pens and bruxism).

Association between Smoking during Pregnancy and Short Root Anomaly in Offspring.

Short root anomaly (SRA) is a dental anomaly with short dental roots and its pathogenesis is poorly understood. This study investigated the association between maternal smoking during pregnancy and SRA in offspring. A survey was conducted on 558 children aged 8-16 years from two public schools in Ulaanbaatar, Mongolia.

Dental Caries in Children Under Five Years of Age in Mongolia.

During the Japan International Cooperation Agency (JICA) partnership program in Mongolia, six times between October 2017 and October 2019, education for caries prevention, a questionnaire of daily oral health behavior, and an oral examination for parents and children aged 0-5 years old were done. The target parent population were middle socio-economic class families. In total, there were 2223 participants.

Associations between Malocclusion and Oral Health-Related Quality of Life among Mongolian Adolescents.

Malocclusion may affect oral health-related quality of life (OHR-QoL), however, the previously detected associations were affected by confounding factors. We hypothesized that there is indeed an association between OHR-QoL and malocclusion and investigated in a population-based study of 420 Mongolian adolescents mean age: 12.6 (standard deviation (SD) = 1.

Association between maternal education and malocclusion in Mongolian adolescents: a cross-sectional study.

Objective: Malocclusion is a highly prevalent condition, affecting 20-60% of adolescents worldwide. Although its treatment is often expensive and unaffordable for disadvantaged individuals, few studies have examined the relationship between malocclusion and socioeconomic status. We investigated the prevalence of malocclusion among Mongolian adolescents and its association with maternal education in a community-based sample in Mongolia.

Comparison of mesiodistal tooth crown diameters and arch dimensions between modern Mongolians and Japanese.

The purposes of this study were to establish normative data for mesiodistal tooth crown diameters and arch dimensions in Mongolian adults and to compare them with those of Japanese adults. The study materials comprised dental casts of 100 modern Mongolian and 100 Japanese subjects (50 males, 50 females for each) with Angle Class I normal occlusion. The mean ages were 20 years 8 months for the Mongolian subjects and 20 years 0 months for the Japanese subjects.

Influence of environmental factors on tooth displacement.

An analysis of static occlusion including occlusal force and occlusal contact area in intercuspal position may be helpful but a dynamic analysis of occlusion should be regarded as more important for analyzing the stomatognathic system. Anthropological research has shown that the Japanese and the Mongolian populations share morphological and genetic similarities, although their dietary lives are not the same. The purpose of this study was to evaluate the relationship between environmental factors such as dietary life and stomatognathic function with a dynamic analysis of physiological tooth displacement.
