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.

Maternal age at birth and other risk factors in early childhood caries.

Purpose: The objective of this study was to identify the impact of mother's age and other child care practices on the children's oral health.

Methods: The study consisted of 646 mother-child pairs who participated in the community oral health program at 1.5 and 3 years old.

Plasma-based fluorine ion implantation into dental materials for inhibition of bacterial adhesion.

The aims of this study were to evaluate the fluorine depth profiles of pure titanium (Ti), stainless steel (SUS), and polymethyl methacrylate (PMMA) modified by plasma-based fluorine ion implantation and the effects of fluorine ion implantation on contact angle, fluoride ion release, and S. mutans adhesion. Fluorine-based gases used were Ar+F2 and CF4.

Metaphyseal dysplasia of Braun-Tinschert type: report of a Japanese girl.

We report on a 7-year-old Japanese girl with metaphyseal dysplasia (MD) of Braun-Tinschert type, a recently recognized, autosomal dominant sclerosing bone dysplasia. All individuals with the disorder from four families in the literature originated from a small town in Bohemia or its vicinity. The occurrence of the disorder in a Japanese girl indicates that it is not restricted to Germans.

CNBP regulates forebrain formation at organogenesis stage in chick embryos.

We recently demonstrated that Cellular Nucleic acid Binding Protein (CNBP)(-/-) mouse embryos exhibit forebrain truncation due to a lack of proper morphogenetic movements of the anterior visceral endoderm (AVE) during pre-gastrulation stage (Chen, W., Liang, Y., Deng, W.

The mesiodistal crown diameters of primary dentition in Indonesian Javanese children.

Dentition analysis of primary teeth is necessary for recognising and correcting occlusal problems in every stage of dental development to enable normal adult occlusion. To do this, normative data of mesiodistal tooth crown diameters from the same ethnic population are needed. The aims of this study were to gather normative data of mesiodistal crown diameters of primary dentition in Indonesian Javanese children and to compare this normative data with published data of other ethnic populations.

The effect of adding hydroxyapatite on the flexural strength of glass ionomer cement.

This present study investigated the effects of the addition of hydroxyapatite (HA) on the flexural strength and microstructure of conventional GIC, and its effect on the cement's initial flexural strength at different storage conditions. Specimens were fabricated by mixing HA in whisker or granule form into commercially prepared GIC, and these were subjected to a three-point bending test and SEM observations. Some specimens were stored in different conditions from dry to wet for 15 minutes to an hour prior to testing.

Toughness, bonding and fluoride-release properties of hydroxyapatite-added glass ionomer cement.

Improving the mechanical strength of glass ionomer cement while preserving its favorable clinical properties such as fluoride release, bonding to tooth structure and biocompatibility is desirable. In this study, hydroxyapatite was incorporated into chemically setting glass ionomer cement and its effect on the fracture toughness, bonding to dentin and fluoride release was identified. Commercial glass ionomer cement (Fuji IX GP((R)) ) was the control and base material.
