“…These changes in properties may affect the likelihood of different types of wear and fractures (Lawn et al, 2013;Akkus et al, 2017). Relevant to the present study, mechanical properties have been shown to vary between buccal and lingual molar crown positions in humans (Shen et al, 2020;Cuy et al, 2002), suggesting these differences may affect the fracture susceptibility of different surfaces. How prism orientation interacts with occlusal loads was also shown to influence wear and fractures in different mammal species (Rensberger and Koenigswald, 1980;Spears, 1997;Shimizu et al, 2005;He and Swain 2008).…”

“…Mineral crystals have a limited capacity to maintain material integrity in a functional environment via fluid percolation, but the sensing mechanisms if any for mineral adaptation are unclear. Fluid percolates through enamel and optimizes physical properties by maintaining crystalline integrity of HA [124]. Formation of FA further stabilizes the mineral component and inhibits demineralization.…”

“…Dental loading induces a transient flux in the microporosity fluid which may produce mechanical signals at the dentinal interface (Fig. 2) [124]. The DEJ is a very sensitive area well known to restorative dentists because a patient must be well anesthetized to achieve pain-free operative dentistry when the DEJ is surgically penetrated.…”

Purpose of the Review Compare pathophysiology for infectious and noninfectious demineralization disease relative to mineral maintenance, physiologic fluoride levels, and mechanical degradation. Recent Findings Environmental acidity, biomechanics, and intercrystalline percolation of endemic fluoride regulate resistance to demineralization relative to osteopenia, noncarious cervical lesions, and dental caries. Summary Demineralization is the most prevalent chronic disease in the world: osteoporosis (OP) >10%, dental caries ~100%. OP is severely debilitating while caries is potentially fatal. Mineralized tissues have a common physiology: cell-mediated apposition, protein matrix, fluid logistics (blood, saliva), intercrystalline ion percolation, cyclic demineralization/remineralization, and acid-based degradation (microbes, clastic cells). Etiology of demineralization involves fluid percolation, metabolism, homeostasis, biomechanics, mechanical wear (attrition or abrasion), and biofilm-related infections. Bone mineral density measurement assesses skeletal mass. Attrition, abrasion, erosion, and abfraction are diagnosed visually, but invisible subsurface caries <400μm cannot be detected. Controlling demineralization at all levels is an important horizon for cost-effective wellness worldwide.

The abilities of scanning electron microscopy (SEM) and focused ion beam (FIB) milling for obtaining high-resolution images from top surfaces, cross-sectional surfaces, and even in three dimensions, are becoming increasingly important for imaging and analyzing tooth structures such as enamel and dentin. FIB was originally developed for material research in the semiconductor industry. However, use of SEM/FIB has been growing recently in dental research due to the versatility of dual platform instruments that can be used as a milling device to obtain low-artifact cross-sections of samples combined with high-resolution images. The advent of the SEM/FIB system and accessories may offer access to previously inaccessible length scales for characterizing tooth structures for dental research, opening exciting opportunities to address many central questions in dental research. New discoveries and fundamental breakthroughs in understanding are likely to follow. This review covers the applications, key findings, and future direction of SEM/FIB in dental research in morphology imaging, specimen preparation for transmission electron microscopy (TEM) analysis, and three-dimensional volume imaging using SEM/FIB tomography.
