Deciphering the relative importance of genetic and environmental factors, which play a major role in the prevalence of early childhood caries (ECC), can help clinicians with planning a long-term preventive treatment. The objective of the study was to determine the prevalence and heritability of ECC among monozygotic (MZ) and dizygotic (DZ) twins in Chennai, India, in the year 2013. A cross-sectional study was designed to estimate the prevalence of ECC among twins. Zygosity classification for the survey framework was adapted from a highly accurate parental report questionnaire pertaining to the physical similarity between twins...

A recent genome-wide association study (GWAS) for dental caries nominated the chromosomal region 4q21 near ABCG2, PKD2 and the SIBLING (small integrin-binding ligand N-linked glycoprotein) gene family. In this investigation, we followed up and fine-mapped this region using a tag-SNP (single-nucleotide polymorphism) approach in 13 age- and race-stratified samples from 6 independent studies (N=4089). Participants were assessed for dental caries via intraoral examination and 49 tag-SNPs were genotyped capturing much of the variation in the 4q21 locus...

Transverse maxillary deficiency may be associated with dental crowding, compromised aesthetics and impaired function. Non-surgical correction of maxillary transverse deficiency through rapid maxillary expansion is routinely performed for young patients, however, surgical intervention is generally required for adults. An interdisciplinary treatment approach is necessary to achieve the desired treatment objectives for challenging cases. This case report demonstrates a pleasing treatment outcome for a patient with a severe maxillary transverse deficiency, significant crowding and extensive active caries...

During caries, dental pulp expresses a range of pro-inflammatory cytokines in response to the infectious challenge. Interferon gamma (IFN-γ) is a dimerized soluble cytokine, which is critical for immune responses. Previous study has demonstrated that IFN-γ at relative high concentration (100 ng/mL) treatment improved the impaired dentinogenic and immunosuppressive regulatory functions of disease-derived dental pulp stem cells (DPSCs). However, little is known about the regulatory effects of IFN-γ at relative low concentration on healthy DPSC behavior (including proliferation, migration, and multiple-potential differentiation)...

INTRODUCTION: The oral health of rural Australians continues to lag behind that of those living in metropolitan areas. Research has shown that people living in rural areas are more likely to suffer from dental caries (decay), visit the dentist less often and have poorer access to oral health services. The purpose of the study was to examine hospitalisations for dental conditions and utilisation of public dental services in three rural communities in Queensland compared with the whole of Queensland...

BACKGROUND: Lifetime access to fluoridated water (FW) is associated with lower caries experience. However, assessing this association in adults is likely affected by age. Cohort stratification and categorization of per cent lifetime access to fluoridated water (% LAFW) within cohorts are current approaches to this assessment. These approaches require an examination of the % LAFW and caries experience variation within and across age groups and their association to inform future analyses...

Achieving oriented and ordered remineralization on the surface of demineralized dental enamel, thereby restoring the satisfactory mechanical properties approaching those of sound enamel, is still a challenge for dentists. To mimic the natural biomineralization approach for enamel remineralization, the biological process of enamel development proteins, such as amelogenin, was simulated in this study. In this work, carboxymethyl chitosan (CMC) conjugated with alendronate (ALN) was applied to stabilize amorphous calcium phosphate (ACP) to form CMC/ACP nanoparticles...
