“…In this study, the laser delivers high energy in the form of light to the tissue; the laser vaporizes the dental follicle tissues that are in contact with laser; then, the defects or injuries in the dental follicle would lead to the abnormal eruption of the molar. 57 Unerupted or impacted wisdom teeth are one of the most common dental diseases that affects about 25% to 50% of the population 6 , 58 , 59 ), and early surgical removal could greatly reduce the risks of inferior alveolar nerve) injury and bone defects. 60 Our previous study indicates that ICG-NIRF dental imaging could detect not only naturally abnormal erupted molars but also laser-treated molars.…”

. Significance: X-ray imaging serves as the mainstream imaging in dentistry, but it involves risk of ionizing radiation. Aim: This study presents the feasibility of indocyanine green-assisted near-infrared fluorescence (ICG-NIRF) dental imaging with 785-nm NIR laser in the first (ICG-NIRF-I: 700 to 1000 nm) and second (ICG-NIRF-II: 1000 to 1700 nm) NIR wavelengths. Approach: Sprague Dawley rats with different postnatal days were used as animal models. ICG, as a fluorescence agent, was delivered to dental structures by subcutaneous injection (SC) and oral administration (OA). Results: For SC method, erupted and unerupted molars could be observed from ICG-NIRF images at a short imaging time ( ). ICG-NIRF-II could achieve a better image contrast in unerupted molars at 24 h after ICG injection. The OA could serve as a non-invasive method for ICG delivery; it could also cause the glow-in-dark effect in unerupted molars. For erupted molars, OA can be considered as mouthwash and exhibits outstanding performance for delivery of ICG dye; erupted molar structures could be observed at a short imaging time ( ) and low ICG dose ( ). Conclusions: Overall, ICG-NIRF with mouthwash could perform in-vivo dental imaging in two NIR wavelengths at a short time and low ICG dose.

“…Oral diseases and disorders, such as abnormal or impacted teeth, continue to sweep the human population . Specifically, over 25% of the population suffer from impacted teeth (delayed or failed eruption), with the highest incidence occurring on the third molar (wisdom teeth) . Early detection of problematic teeth is important for making treatment plans, such as timely removal of the eruption barrier to allow eruption of impacted teeth spontaneously .…”

In this study, we used rat animal model to compare the efficiency of indocyanine green (ICG)-assisted dental near-infrared fluorescence imaging with X-ray imaging, and we optimized the imaging window for both unerupted and erupted molars. The results show that the morphology of the dental structures was observed clearly from ICG-assisted dental images (especially through the endoscope). A better image contrast was easily acquired at the short imaging windows (<10 minutes) for unerupted and erupted molars. For unerupted molars, there is another optimized imaging window (48-96 hours) with a prominent glowin-the-dark effect: only the molars remain bright. This study also revealed that the laser ablation of dental follicles can disrupt the molar development, and our method is able to efficiently detect laser-treated molars and acquire the precise morphology. Thus, ICG-assisted dental imaging has the potential to be a safer and more efficient imaging modality for the real-time diagnosis of dental diseases.fluorescence dental imaging, indocyanine green, laser treatment, near-infrared, optimal imaging window

X-ray-based imaging, including computed tomography, plays a crucial role in the diagnosis and surgery of impacted teeth that affects over 25% of the human population. But the greatest disadvantage of this technique is ionizing radiation risk to the patients. Here we describe a completely ionizing-radiation-free in vivo near-infrared (NIR) fluoresence dental imaging with indocyanine green (ICG) agent that has rarely been applied in dental imaging. Our method can acquire dental structure images within a short period (only 10 minutes after injection) without ionizing radiation risk. NIR enables the observation of dental structures that are not distinguishable under visible conditions. At prolonged 72 hours, only molar regions remained highlighted; the contrast between molar regions and surrounding tissues was prominent; this is particularly useful for in vivo dental imaging. Using the quantitative spectral analysis, we found the peak wavelengths of ICG fluorescence shifted along with the injection time: the peak wavelength shifted 8 nm (from 819 nm to 811 nm) in 0~72 hours. The injection methods of tail vein v.s . intradermal injections caused ~3 nm shift. ICG-assisted NIR fluorescence imaging can serve as a useful tool for in vivo real-time diagnosis in dental clinics and surgeries without ionizing radiation risk.
