“…There are two main methods to prepare artificial caries: chemical and biofilm methods. Chemical methods can be used for enamel surface by adjusting the chemical state and pH of a using a partially saturated buffer [37,38] or an acid gel [39]. This method is easy and the most widely used, while a biofilm method is performed by placing a cariogenic suspension on the surface of the tooth, altering the metabolic environment of the bacteria and creating a carious sample that more closely resembles natural caries [40,41].…”

“…Reliable detection of invisible caries in lesions as shallow as 20μm would be valuable for assessing the risk of fixed appliances prior to orthodontic treatment. As subsequently discussed, multiple available and developmental technologies are being evaluated in this regard [4,5,72]. However, there is no innocuous method available for detecting invisible carious lesions before characteristic white spots become visible.…”

“…Multiple new technologies are available or are in development for detecting incipient caries: fiber-optic trans-illumination, quantitative light-induced fluorescence (QLF), digital image fiber-optic trans-illumination, electrical conductance measurement, digital subtraction radiography, laser fluorescence measurement, and ultrasound caries detection [97]. In addition, optical coherence tomography systems are effective for noninvasive assessment of hard dental tissues [72,98]. The emphasis for most new device development is on pits, fissures, and interproximal caries [99].…”

Purpose of Review Compare noninfectious (part I) to infectious (part II) demineralization of bones and teeth. Evaluate similarities and differences in the expression of hard tissue degradation for the two most common chronic demineralization diseases: osteoporosis and dental caries. Recent Findings The physiology of demineralization is similar for the sterile skeleton compared to the septic dentition. Superimposing the pathologic variable of infection reveals a unique pathophysiology for dental caries. Summary Mineralized tissues are compromised by microdamage, demineralization, and infection. Osseous tissues remodel (turnover) to maintain structural integrity, but the heavily loaded dentition does not turnover so it is ultimately at risk of collapse. A carious tooth is a potential vector for periapical infection that may be life-threatening. Insipient caries is initiated as a subsurface decalcification in enamel that is not detectable until a depth of ~400μm when it becomes visible as a white spot. Reliable detection and remineralization of invisible caries would advance cost-effective wellness worldwide.

Quantitative Assessment Methods of Early Enamel Caries with Optical Coherence Tomography: A Review

et al. 2022

View full text Add to dashboard Cite

Early detection of caries is an urgent problem in the dental clinic. Current caries detection methods do not detect early enamel caries accurately, and do not show microstructural changes in the teeth. Optical coherence tomography (OCT) can provide imaging of tiny, demineralized regions of teeth in real time and noninvasively detect dynamic changes in lesions with high resolution and high sensitivity. Over the last 20 years, researchers have investigated different methods for quantitative assessment of early caries using OCT. This review provides an overview of the principles of enamel caries detection with OCT, the methods of characterizing caries lesion severity, and correlations between OCT results and measurements from multiple histological detection techniques. Studies have shown the feasibility of OCT in quantitative assessment of early enamel lesions but they vary widely in approaches. Only integrated reflectivity and refractive index measured by OCT have proven to have strong correlations with mineral loss calculated by digital microradiography or transverse microradiography. OCT has great potential to be a standard inspection method for enamel lesions, but a consensus on quantitative methods and indicators is an important prerequisite. Our review provides a basis for future discussions.
