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).

Perception and attitude of Mongolians on malocclusion.

Background/purpose: This study assessed the perception and attitude of Mongolians on malocclusion and compared the perceptions with researchers' perceptions on malocclusion, and this study aimed to determine factors influencing the self-perception of laypeople.

Materials And Methods: In addition, we evaluated the correlation between the subjective and objective perceptions of participants. In a random sample of 133 people (39.

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.

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.

Effect of angiotensin II receptor blocker on experimental periodontitis in a mouse model of Marfan syndrome.

Marfan syndrome is an autosomal dominant disease characterized by aneurysm and dilatation of the aortic root, tall stature, and ectopia lentis. These manifestations reflect excessive signaling of transforming growth factor beta (TGF-β). Moreover, cases are frequently associated with severe periodontitis, which is a chronic inflammation of the gingiva, periodontal ligament, and alveolar bone.

ADAMTSL6β protein rescues fibrillin-1 microfibril disorder in a Marfan syndrome mouse model through the promotion of fibrillin-1 assembly.

Marfan syndrome (MFS) is a systemic disorder of the connective tissues caused by insufficient fibrillin-1 microfibril formation and can cause cardiac complications, emphysema, ocular lens dislocation, and severe periodontal disease. ADAMTSL6β (A disintegrin-like metalloprotease domain with thrombospondin type I motifs-like 6β) is a microfibril-associated extracellular matrix protein expressed in various connective tissues that has been implicated in fibrillin-1 microfibril assembly. We here report that ADAMTSL6β plays an essential role in the development and regeneration of connective tissues.

Dilated capillaries, disorganized collagen fibers and differential gene expression in periodontal ligaments of hypomorphic fibrillin-1 mice.

The periodontal ligaments (PDLs) are soft connective tissue between the cementum covering the tooth root surface and alveolar bone. PDLs are composed of collagen and elastic system fibers, blood vessels, nerves, and various types of cells. Elastic system fibers are generally formed by elastin and microfibrils, but PDLs are mainly composed of the latter.

Marfan syndrome and its disorder in periodontal tissues.

Elastic system fibers are composed of two distinct elements, elastin, which is an amorphous component crosslinked in the core, and microfibril, localized in the periphery of elastin. As microfibrillar proteins, fibrillins, microfibril-associated glycoproteins (MAGPs), latent TGF-beta-binding proteins (LTBPs), microfibril-associated proteins (MFAPs), and fibulins are known. Fibrillin-1 is a major microfibrillar protein and characterized by calcium binding EGF-like (cbEGF) domain.
