Dental Applications of Optical Coherence Tomography (OCT) in Cariology

Across all medical disciplines, therapeutic interventions are based on previously acquired diagnostic information. In cariology, which includes the detection and assessment of the disease "caries" and its lesions, as well as non-invasive to invasive treatment and caries prevention, visual inspection and radiology are routinely used as diagnostic tools. However, the specificity and sensitivity of these standard methods are still unsatisfactory and the detection of defects is often afflicted with a time delay. Numerous novel methods have been developed to improve the unsatisfactory diagnostic possibilities in this specialized medical field. These newer techniques have not yet found widespread acceptance in clinical practice, which might be explained by the generated numerical or color-coded output data that are not self-explanatory. With optical coherence tomography (OCT), an innovative image-based technique has become available that has considerable potential in supporting the routine assessment of teeth in the future. The received cross-sectional images are easy to interpret and can be processed. In recent years, numerous applications of OCT have been evaluated in cariology beginning with the diagnosis of different defects up to restoration assessment and their monitoring, or the visualization of individual treatment steps. Based on selected examples, this overview outlines the possibilities and limitations of this technique in cariology and restorative dentistry, which pertain to the most clinical relevant fields of dentistry.

“…Further applications are found in dermatology [23,24] and cardiology [25]. The first images of human dental tissues were presented by Colston et al [26,27] and Feldchtein et al [28]. Since then, the number of studies using OCT have increased markedly [29,30].…”

“…In that same year, they presented in vivo OCT images of human dental tissues. 61 For this purpose, they developed a novel dental OCT system that incorporated a sample arm and scanning optics into a handpiece instrument. Their system had a lateral resolution of 50 ㎛ and an average total lateral scan distance of 12 mm.…”

Early detection of carious lesions increases the possibility of treatment without the need for surgical intervention. Optical coherence tomography (OCT) is an emerging three-dimensional imaging technique that has been successfully used in other medical fields, such as ophthalmology for optical biopsy, and is a prospective candidate for early caries detection. The technique is based on low coherence interferometry and is advantageous in that it is non-invasive, does not use ionizing radiation, and can render threedimensional images. A brief history of the development of this technique and its principles are discussed in this paper. There have been numerous studies on caries detection, which were mostly in vitro or ex vivo experiments. Through these studies, the feasibility of OCT for caries detection was confirmed. However, further research should be performed, including in vivo studies of OCT applications, in order to prove the clinical usefulness of this technique. In addition, some technological problems must be resolved in the near future to allow for the use of OCT in everyday practice. [J Kor Acad Cons Dent 2011;36(5):367-376.]

“…After collecting A-scan, combining a series of these axial depth scans to form a crosssectional tomography is called a "B-scan". Up to now, OCT has been already widely used in clinical application such as ophthalmology [2][3][4][5][6] and dentistry [7][8][9][10]. OCT is currently divided into two main categories: time-domain OCT (TD-OCT) and frequency-domain OCT (FD-OCT).…”

Abstract:Optical coherence tomography is a powerful tool that can e ectively provide detail information of biological tissue structure. The axis resolution of optical coherence tomography has achieved sub-micrometer and we are interested in its ultrahigh resolution that can be practically utilized for clinical application. In this article, the basic system calibration is discussed; we systematically demonstrated the detail process in optimization of optical coherence tomography for accurately acquiring data. The systematic optimization for optical coherence tomography imaging is discussed here including system calibration and image post-processing.
