Nanoidentification in endodontics: Bibliometric analysis and comprehensive review on the basis of characterisation research by Nano-computed tomography imaging.

Nanoimaging, crucial in endodontics, has advanced, leading to more effective and less invasive treatments. Nano-computed tomography (nano-CT) is an advanced imaging technique to evaluate bone structures or gaps in filling materials, providing submicrometer spatial resolution due to smaller focal points and voxels, higher signal-to-noise ratios, and higher tube voltages and powers compared to conventional devices, improving dental imaging precision and safety by producing detailed images with minimal radiation exposure. This study conducted a bibliometric analysis on nano-CT imaging as a nano identification tool in endodontics. Using various tools and methods, it evaluated progress and trends in nano-CT, aiming to enhance understanding of bibliometric data and complement existing endodontic knowledge. Nano-CT imaging has gained prominence in endodontics research, offering potential applications and insights into various aspects of the field. A review of relevant studies highlighted the technique's ability to visualize dentin tubules, root canal anatomy, filling quality, root resorption, cracks, microcracks, soft dental tissues, cellular layers, volumetric changes post-instrumentation, hard tissue debris, root surface deposits, and bioceramic pore structures. Nano-CT has the potential to become the gold standard for imaging in endodontics, presenting opportunities and challenges for future research. These findings provide researchers and practitioners with the latest advancements in nanoimaging.
