“…This solution has been published in work [ 72 ]. There are also a few other possibilities for using the quantitative analysis of the intraoral structures and tissue conditions such as dental enamel and dental caries [ 86 ], dental abfraction and attrition [ 98 ], enamel erosion [ 101 ], enamel demineralization [ 109 ], thickness of dentin layer [ 121 ], and soft tissues [ 173 ].…”

Optical coherence tomography provides sections of tissues in a noncontact and noninvasive manner. The device measures the time delay and intensity of the light scattered or reflected from biological tissues, which results in tomographic imaging of their internal structure. This is achieved by scanning tissues at a resolution ranging from 1 to 15 μm. OCT enables real-time in situ imaging of tissues without the need for biopsy, histological procedures, or the use of X-rays, so it can be used in many fields of medicine. Its properties are not only particularly used in ophthalmology, in the diagnosis of all layers of the retina, but also increasingly in cardiology, gastroenterology, pulmonology, oncology, and dermatology. The basic properties of OCT, that is, noninvasiveness and low wattage of the used light, have also been appreciated in analytical technology by conservators, who use it to identify the quality and age of paintings, ceramics, or glass. Recently, the OCT technique of visualization is being tested in different fields of dentistry, which is depicted in the article.

“…It has a high axial resolution of about 10 μm, which provides sufficient information for dental clinical applications such as the detection of cracks and microleakage. One study 59 described microleakage sensing based on (SS-OCT), where the calculated length was 401 μm and the width was 148 μm, which is not significantly different from histological biopsy measurements. In addition, the authors compared various methods currently used in general dentistry for diagnosis.…”

The clinical success of esthetic restorations, including composite resins, depends on the quality and durability of the interface between the tooth and restoration. Current commercially available materials do not possess ideal sealing at the marginal interfaces, and marginal microleakage leads to clinically significant issues for patients and clinicians. Many factors may affect microleakage formation, including the adaptation of composite resins to the tooth surface, the adhesive system used, and the polymerization shrinkage of the materials. The evolution of restorative materials, designed to achieve low shrinkage and improve mechanical properties, could lead to restorations with improved clinical performance. Furthermore, searching for clinical techniques to optimize the integrity of resin/dentin bonds is significant, and the evaluation of microleakage is also critical to the assessment of restorative materials. The objective of this paper was to review the literature on the recent advances in restorative materials, the potential applications of clinical techniques, and the methods of measuring microleakage.

“…In dental science, OCT detects qualitative and quantitative morphological changes of dental hard and soft tissues, like for early diagnosis of dental diseases, such as caries, periodontal disease, and oral cancer, because of the excellent spatial resolution (≈15 μm) [102]. OCT can also be used in other types of applications [99][100][101], such as to evaluate the microleakage of dental restorations and endodontic fillings [103], the dental implant status [104], the integrity of dental prosthesis [105], and the surroundings of orthodontic brackets [106].…”

“…Although they demonstrate the proof-of-concept of a dental drill, they did not succeed perfectly. More recently, Sun et al [102] developed a swept-source optical coherence tomography (SS-OCT) system, using a fiber optic handheld scanning probe, for the diagnosis in real-time of crack and microleakage detection between dental composite resin and enamel. The system uses a 1310 nm swept-source laser as a broadband light source, which is separated into two arms (reference arm and sampling arm) and after that is recoupled in another optical coupler for interference.…”
