“…In the past, initial changes in the enamel have been visualized in detail only histologically. In vitro OCT studies [26,27] also compare mineral loss and lesion depth using digital microradiography or transverse microradiography [28] as a reference, since this is currently considered as the gold standard of early caries detection. The disadvantage of comparing histological techniques is that samples from the experiment have to be destroyed.…”

Early caries diagnosis still challenges dentistry. Polarization-sensitive optical coherence tomography (PS-OCT) is promising to detect initial lesions non-invasively in depth-resolved cross-sectional visualization. PS-OCT with determined degree of polarization (DOP) imaging provides an intuitive demineralization contrast. The aim of this study is to evaluate the suitability of DOP-based PS-OCT imaging to monitor controlled de- and remineralization progression for the first time and to introduce it as a valid, non-destructive in vitro detection method. Twelve standardized bovine enamel specimens were divided in different groups and demineralized with hydrochloric acid (HCl) as well as partly remineralized with fluoride over a 14-day pH-cycling experiment. The specimens were stored in artificial saliva and sodium chloride (NaCl), respectively. Progress measurements with PS-OCT were made with polarization-sensitive en faceand B-scan mode for qualitative evaluation. The specimens demineralized in HCl showed the most pronounced surface change (lowest DOP) and the most significant increase in depolarization. Additional fluoride treatment and the storage in artificial saliva resulted in the opposite (highest DOP). Therefore, DOP-based PS-OCT imaging appears to be a valuable technique for visualization and monitoring of enamel demineralization and remineralization processes in vitro. However, these findings need to be confirmed in human teeth ex vivo or in situ.

“…The analysis using OCT reveals mineral loss and accurately gauges the extent of demineralization within the lesion. It also allows for a more objective and precise assessment of the intensity of initial enamel carious lesions, as the quantifiable index obtained through OCT correlates significantly with enamel demineralization [65].…”

In our technology-driven world, rising dental injuries have prompted re-evaluation of treatment methods. Key focuses include preventing carious lesions through early detection and good oral hygiene. Precise diagnostic tools enable tailored treatments, such as fluoridation, sealing, pH-adjusting diets, resin infiltration, and ozone remineralization. Dental enamel is crucial for tooth function. Researchers aim to replicate its complex structure for biocompatible materials. Hydroxyapatite’s unique properties are vital for hard tissues like bones, enamel, and dentin. Enamel development involves ameloblasts in pre-eruptive and post-eruptive stages. Saliva aids post-eruptive maturation but can lead to bacterial adhesion and enamel demineralization. Preventing enamel demineralization hinges on ion transport and critical pH levels, while low calcium levels impact enamel cells. Dietary sugars interact with bacteria, causing demineralization, but saliva aids remineralization. Caries risk depends on factors like diet, oral hygiene, and tooth morphology. Personalized approaches like Caries Management by Risk Assessment (CAMBRA) for caries risk assessment (CRA) are crucial. Traditional enamel protection methods involve fluoride and dental sealants, but concerns exist about fluoride toxicity and bacterial resistance. Modern alternatives include resin infiltration for early caries, argon laser technique for lesion protection, and ozone therapy to combat decay, offering noninvasive options for enamel care.

Many advanced imaging modalities, such as magnetic resonance imaging (MRI), X-ray Computed Tomography, Positron Emission Tomography (PET), Ultrasound, Single Photon Emission Computed Tomography (SPECT), and the most recent, Optical Coherence Tomography (OCT), have been developed for identifying dental tissues images and detecting changes in early carious lesions. Some modalities use high doses of radiation and energy to obtain more information, which may be harmful to patient’s health. Most early commercial OCTs had drawbacks such as its bulky size and limited image resolution. In order to overcome these concerns, this paper presents a dual-mode tomography technique that combines OCT and ultrasound method using the COMSOL Multiphysics. The application of an ultrasound device helps overcome the limitation of OCT in detecting the penetration depth of a caries lesion. Several simulations were performed to analyse the light and ultrasonic propagated waves with different diameters of carious lesions. In response to this goal, the combination data of OCT and ultrasound provide a 3D image which offers the best approach for displaying and examining changes in the oral cavity.
