Evo-devo models of tooth development and the origin of hominoid molar diversity

Abstract The detailed anatomical features that characterize fossil hominin molars figure prominently in the reconstruction of their taxonomy, phylogeny, and paleobiology. Despite the prominence of molar form in human origins research, the underlying developmental mechanisms generating the diversity of tooth crown features remain poorly understood. A model of tooth morphogenesis—the patterning cascade model (PCM)—provides a […]

Biomimetic Tooth Repair: Amelogenin-Derived Peptide Enables in Vitro Remineralization of Human Enamel

Abstract: White spot lesions (WSL) and incipient caries on enamel surfaces are the earliest clinical outcomes for demineralization and caries. If left untreated, the caries can progress and may cause complex restorative procedures or even tooth extraction which destroys soft and hard tissue architecture as a consequence of connective tissue and bone loss. Current clinical […]

An Alzheimer’s drug might be able to repair cavities in teeth

A recent discovery about an Alzheimer’s drug may lead to the end of cavity fillings in teeth as we know them. Scientists discovered the drug, Tideglusib, promoted natural tooth regrowth during its clinical trials on mice, which led to total repair of cavities. They learned the drug stimulates stem cells in teeth, which creates new […]

The dome technique: a new surgical technique to enhance soft-tissue margins and emergence profiles around implants placed in the esthetic zone

Abstract: Achieving symmetry of the soft-tissue margins between anterior maxillary dental-implant restorations and adjacent teeth is a therapeutic challenge for both the implant surgeon and the restorative dentist. This article describes a modified procedure utilizing autogenous connective-tissue grafts to improve primarily buccal soft-tissue margins and secondarily interproximal tissues around tooth-bound single dental implants. This technique […]
