“…Because of bundled fibers, the endoscopic system can produce low-contrast images, which have poor resolution in diagnosis. Recently, many researchs have been aimed to improve the obtained images by enhancing hardware and software (17) or test the endoscope to detect the limitations in root canal (14).…”

The aim of this study was to evaluate the efficacy of endoscopic visualisation to detect the presence and type of isthmuses within the mesial root canals of mandibular first molar teeth compared with micro-computed tomography (micro-CT) images as reference. Materials and Methods Thirty-two mesial roots of mandibular first molars presenting isthmuses were selected based on micro-CT scans. In all, 12 type I and 20 band-shaped isthmuses were collected. The specimens were mounted in the posterior socket of dental phantom manikin for endoscopic visualisation. The ability of endoscopes to visualize the presence of isthmuses and distinguish the type of isthmuses was compared. Micro-CT images of the specimens were used as references. Data were analyzed using Fisher's exact tests. Results Sensitivity of endoscope to detect isthmuses were also calculated for each isthmus type. In 37.5% of the samples, isthmus presence was correctly diagnosed via orthograde endoscopic visualization. Type I istmuses were significantly more detected than band-shaped isthmuses (P<0.05). Endoscope showed higher sensitivity to detect type I isthmus than band-shaped isthmus. Conclusion The endodontic endoscope could detect type I isthmuses more accurately than band-shaped isthmuses.

“…Endoscopes can realize the microtransportation of light-curing materials, compare the effect of apical surgery, explore root canals, observe dental pulp, and realize root canal visualization [38][39][40]. In 2018, an endoscopic system based on an intraoral camera and image processing was reported [41]. is system is the first step to facilitating the observation of fine structures by intraoral cameras.…”

Robotic and microrobotic tools such as dental operating microscopes and dental endoscopes are being used extensively in dental therapy, which have a significant impact on dental therapy and education. Herein, this paper reviews the state of the art of robotic and microrobotic tools for dental therapy. This article starts with a brief introduction of current robotic and microrobotic tools for dental therapy and then displays their applications in various dental problems; strengths and weaknesses are also surveyed. Lastly, the conclusion and outlook are discussed, referring to the emerging dental clinic problems and demands. This review is expected to provide guidelines for the therapeutic application of robotic and microrobotic tools and to promote the development of robots in dentistry.

Biological vision offers intriguing inspiration for functional features in imaging systems with small form factors. We report biologically inspired intraoral camera (BIOC) for assorted dental imaging. This fully packaged BIOC features a convex-concave lens, inverted microlens arrays (iMLAs), LED module, and a single CMOS image sensor on a flexible printed circuit board in a handpiece holder. The iMLAs also collect light from wide angles by mounting the convex-concave lens to increase the viewing angle. The clinical trials have been successfully conducted for real-time and multifunctional intraoral monitoring of human teeth, including infinite depth of field, close-up, wide field-of-view, three-dimensional, and autofluorescence imaging. This biomedical camera provides insights for functional imaging not only in dental applications but also in surgical robots and endoscopy applications.
