“…As reported in a clinical study for caries diagnosis (Park et al, 2021), OCT, as it exists today, is most feasible for use on the buccal surfaces of anterior teeth, up to the premolars; therefore, its use for the clinical diagnosis of MIH should still be considered limited. However, Schneider et al (2020) introduced a new OCT probe for intraoral use to diagnose interproximal lesions, and this probe was also evaluated more recently by Son et al (2023) who reported good results with permanent second molars. Currently, there is a trend to combine multiple technologies in a single device.…”

Molar‐incisor hypomineralization (MIH) is a qualitative defect of dental enamel characterized by demarcated opacities present in permanent first molars and other teeth. It is considered a major clinical challenge in dentistry because it makes affected teeth more susceptible to fractures and dental caries. Its diagnosis is mainly clinical and there are few technological resources that allow for a more accurate diagnosis, especially with respect to the depth of the defect in the dental enamel. In this context, optical coherence tomography (OCT), which is routinely used in ophthalmology, can produce images of the depth of the dental enamel, making it a promising method. In this study, 33 teeth with different MIH severities were evaluated using OCT and microcomputed tomography (microCT). Semi‐quantitative methods of grayscale pattern analysis were used to compare images obtained from different severities of MIH with the mineral density obtained through microCT. MicroCT evaluation revealed that hypomineralized enamel had a significantly lower mineral density than intact enamel. However, this difference was not observed between the mild and severe MIH lesions. In the OCT evaluation, significant differences were observed between the intact and hypomineralized enamel, and the gray value comparison provided a method for quantitative differentiation between the two. This study suggests that OCT could be a useful adjunct to traditional diagnostic methods for MIH, offering a noninvasive approach to evaluate enamel defects.Research HighlightsCombining optical coherence tomography with grayscale digital analysis shows potential as a promising method for diagnosing molar‐incisor hypomineralization and assessing its level of severity.

“…In vitro studies are useful to simulate circumstances of in vivo studies, but do not fully represent the conditions that distinguish the oral environment. In literature, few studies on partial crown are available for in vivo evaluation [26,29]. Among these methods, 2D analysis in vivo is possible using silicone replica technique or epoxy resin replicas, which represent the only non-invasive methods for patients.…”

“…After this phase, 22 articles were included in the final review. The reasons for the exclusion of studies during this last analysis were the following: evaluation of internal fit only [23,24], pilot studies [25], case reports [26], reviews [20,27,28], in vivo studies [29], publication before 1 January 2017 [30][31][32][33], quantitative analysis of fit not expressed in micrometers or percentage values of continuous margin [34][35][36], analysis on wax models [37] or restorations produced with conventional methods [38][39][40][41][42][43] Figure 1.…”

Background: Different methods are used for the analysis of marginal and internal fit of partial crowns, but not all of them are applicable for in vivo studies. The aim of this review is to search the available methods, described in the current literature, to assess marginal and internal fit in partial crowns. Methods: an electronic search was performed on Pubmed and Web of Science databases to find studies published from 1 January 2017 up to 2 March 2023, following PRISMA guidelines and Cochrane handbook for systematic reviews. The search strategy applied was: “(marginal) AND (fit OR gap OR adaptation OR discrepancy) AND (inlay OR onlay OR partial crown)”. In vitro studies which evaluated marginal and internal fit on CAD CAM or 3D printed partial crowns were included in this review. Quality of the studies was assessed by using Quality Assessment Tool For In Vitro Studies (QUIN tool). Results: 22 studies were included. Among conventional methods, direct view with microscope, indirect view on resin replicas, and silicone replica technique (SRT) were used. Considering new digital methods, micro-CT, SRT 3D and triple scan technique (TST) were applied. Conclusions: Among 2D methods, direct view technique is the most used marginal fit analysis. For a more comprehensive evaluation, a 3D digital analysis is suggested. SRT and indirect view are the only 2D methods available for in vivo analysis. A protocol for the application of TST for assessment in vivo is now available, but no studies are reported in literature yet.

“…Optical coherence tomography (OCT) is non-invasive optical imaging equipment developed based on the Michelson interferometer to visualize tomography information of tissues several millimeters deep below the surface [1]. Thanks to their real-time imaging capabilities and excellent axial and spatial resolution, optical interference tomography devices are used as major examination tools for ophthalmology, dermatology, oncology, and dentistry [2][3][4][5][6][7][8]. In addition to medical and biomedical applications, optical interference tomography devices are widely applied, including industrial and agricultural applications [9][10][11].…”

Research for miniaturization and portability of optical coherence tomography, which has received considerable attention as one of the pre-diagnosis methods, has been conducted for several years to further expand the utility of optical coherence tomography. In this study, we introduce a method that can dramatically reduce the size of a system and resources using a Raspberry Pi miniature computer and the proposed small spectrometer. The optical systems of the sample stage and the reference stage were configured as half-inch optical components to reduce the size of the system. The size of the sample stage was minimized by using a MEMS scanning mirror. We designed a board that converts the unipolar drive signal into a bipolar signal to drive the MEMS scanning mirror with Raspberry Pi. The MEMS mirror was controlled by a commercial AD/DA conversion board and a developed board that can be controlled via the general-purpose input-output (GPIO) pin of Raspberry Pi. Furthermore, we also designed the spectrometer to fit the 1-inch optical system. The camera was selected as a product that can supply power and transmit data through the USB terminal to operate all other components, including the camera, through a portable charger. Due to camera performance limitations, A-scan 5 kHz was the maximum speed, but the resolution was axial 8.5 μm (Air) and lateral 17.54 μm, showing similar performance to a commercial system. Although the operating speed is slow, it is expected to be used in various fields due to its portability advantage.
