Image-based dental analysis, using intraoral photographs, offers a practical and scalable approach to bridge this gap. In this context, we developed SegmentAnyTooth, an open-source deep learning framework that solves the critical first step by enabling automated tooth enumeration and segmentation across five standard intraoral views: upper occlusal, lower occlusal, frontal, right lateral, and left lateral. This tool lays the groundwork for advanced applications, reducing reliance on limited professional resources and enhancing access to preventive dental care.</div></div><div><h3>Materials and methods</h3><div>A dataset of 5000 intraoral photos from 1000 sets (953 subjects) was annotated with tooth surfaces and FDI notations.

Lateral view models also performed well, with mean DSCs of 0.939 ± 0.070 (right) and 0.945 ± 0.056 (left).

The mandible-only surgery could enhance the lower facial symmetry with significant changes observed in the H angle (<em>P</em> &lt; 0.05), SN-MP angle (<em>P</em> &lt; 0.05), and LL-E line distances (<em>P</em> &lt; 0.05).
