TSegFormer: 3D Tooth Segmentation in Intraoral Scans with Geometry Guided Transformer [PDF]
arXiv, 2023 Optical Intraoral Scanners (IOS) are widely used in digital dentistry to provide detailed 3D information of dental crowns and the gingiva. Accurate 3D tooth segmentation in IOSs is critical for various dental applications, while previous methods are error-prone at complicated boundaries and exhibit unsatisfactory results across patients.

Periodontal disease and tooth loss
International Dental Journal, 1998 Numerous epidemiological studies have shown that caries is the main reason for tooth loss. More recent epidemiological data seem to show an increasing trend of tooth loss due to periodontal reasons rather than caries. In considering the issue of periodontal disease and tooth loss the following observations were made.

State of the Art of Low‐Frequency Acoustic Modulation: Intensity Enhancement and Directional Control
Advanced Science, EarlyView.High intensity low‐frequency sound sources hold significant value in many fields. However, their long wavelength, strong penetrability, and tendency to diffract make direction control and intensity enhancement challenging. Acoustic generators and metamaterial‐based acoustic devices still face issues such as low energy efficiency, poor directional ...

OSTEOPOROSIS VERSUS TOOTH LOSS
American Journal of Orthopedic Research and Reviews, 2020 Osteoporosis is a common metabolic disease of the bones that increases bone fragility due to decreased bone mass and bad quality of bone, leading to an increased risk of bone fracture. This disease affects all the bones, including femurs/pelvis, spine, forearms, ribs, mandible, and maxillary bone.

MTSS2‐Related Disorder: Refining the Phenotype in Four New Cases and Literature Review
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT MTSS2 encodes a protein highly expressed in the central nervous system, with a crucial role in neurodevelopment. The de novo recurrent variant c.2011C>T (p.Arg671Trp) was first identified in 2022 as cause of Intellectual Developmental Disorder with ocular anomalies and distinctive facial features (OMIM#620086).
