Although dental caries destroys dental hard tissues, both demineralization as a destructive process and remineralization as a restorative process take place in carious lesions. These conflicting processes occur constantly either simultaneously or alternately. In crystallographic terms, demineralization is crystal dissolution, and remineralization is restoration of partially dissolved crystals, new crystal formation and growth of surviving crystals. In this review, we employ high-resolution transmission electron microscopy to demonstrate demineralization and remineralization of enamel crystals obtained from cross-cut sections of the c-axes of crystals from carious lesions.

Streptococcus mutans, a key cause of dental caries, is not treated by conventional toothpaste, brushing, flossing, or antiseptic mouthwashes. This necessitates the development of enriched toothpaste. Cyanobacteria-derived phycoerythrin (PE) has antioxidant and antibacterial properties.

Background: Mouth breathing (MB) is a pediatric public health concern potentially increasing dental caries risk. We investigated risk factors, relationships between clinical characteristics and medical costs, and their effects on caries severity.
Study Design: Observation study.

Childhood obesity is an escalating global public health concern with potential long-term implications for various health outcomes, including oral health. While the association between childhood obesity and systemic diseases is well-documented, its specific impact on adult oral health remains underexplored. This study utilized a 2-sample Mendelian randomization approach to explore the causal relationship between childhood obesity and several adult oral health conditions, including gingivitis, chronic periodontitis, dental caries, temporomandibular joint disorder, and malocclusion.
