Tooth structure and fracture strength of cavities [PDF]
Brazilian Dental Journal, 2007 This study evaluated, in vitro, the loss of tooth substance after cavity preparation for direct and indirect restorations and its relationship with fracture strength of the prepared teeth. Sixty sound human maxillary first premolars were assigned to 6 groups (n=10).

A White-Box SVM Framework and its Swarm-Based Optimization for Supervision of Toothed Milling Cutter through Characterization of Spindle Vibrations [PDF]
arXiv, 2021 In this paper, a white-Box support vector machine (SVM) framework and its swarm-based optimization is presented for supervision of toothed milling cutter through characterization of real-time spindle vibrations. The anomalous moments of vibration evolved due to in-process tool failures (i.e., flank and nose wear, crater and notch wear, edge fracture ...

Dense Representative Tooth Landmark/axis Detection Network on 3D Model [PDF]
arXiv, 2021 Artificial intelligence (AI) technology is increasingly used for digital orthodontics, but one of the challenges is to automatically and accurately detect tooth landmarks and axes. This is partly because of sophisticated geometric definitions of them, and partly due to large variations among individual tooth and across different types of tooth. As such,

Tooth-shaped plasmonic waveguide filters with nanometeric sizes [PDF]
Opt. Lett. 33, 2874-2876 (2008), 2009 A novel nanometeric plasmonic filter in a tooth-shaped Metal-Insulator-Metal waveguide is proposed and demonstrated numerically. An analytic model based on the scattering matrix method is given. The result reveals that the single tooth-shaped filter has a wavelength filtering characteristic and an ultra-compact size in the length of a few hundred ...

DArch: Dental Arch Prior-assisted 3D Tooth Instance Segmentation [PDF]
arXiv, 2022 Automatic tooth instance segmentation on 3D dental models is a fundamental task for computer-aided orthodontic treatments. Existing learning-based methods rely heavily on expensive point-wise annotations. To alleviate this problem, we are the first to explore a low-cost annotation way for 3D tooth instance segmentation, i.e., labeling all tooth ...

Assessment of Impact of Malocclusion on Oral Health Status and Oral Health-related Quality of Life among School and College Students of Chennai, Tamil Nadu, India: A Cross-sectional Study [PDF]
Journal of Clinical and Diagnostic ResearchIntroduction: Malocclusion is multifactorial in origin, caused by the interaction of various general and local factors. The consequences of malocclusion include dental caries, periodontitis, impaction of teeth, and compromised chewing abilities. Thus, if
