Existence of inelastic supernumerary nuclear rainbow in $^{16}$O+$^{12}$C scattering [PDF]

Physical Review C 96, 024607 (2017), 2017
The existence of a supernumerary nuclear rainbow in inelastic scattering is reported. This is done by studying inelastic $^{16}$O scattering from $^{12}$C, exciting the $2^+$ (4.44 MeV) state of $^{12}$C and elastic scattering at the incident energies in the range 124 to 200 MeV, using the coupled channels method.

Extraction of Supernumerary Nasal Tooth by Endoscopic Approach

Contemporary Clinical Dentistry, 2021
The occurrence of the supernumerary tooth in the nasal cavity is uncommon. If not diagnosed and treated early, it may lead to various complications. Nasal endoscopy not only helps in proper diagnosis but also is an effective approach towards the extraction of the nasal tooth.

Restoration of human tooth enamel

BMEMat, EarlyView.
Human tooth enamel has remarkable properties but lacks self‐repair ability. Existing restorative materials cannot fully replicate enamel's microstructure and function, resulting in low restorative efficiency. This review summarizes the formation process and characteristics of enamel, and current restorative materials and future research directions are ...

Mandibular Teeth Movement Variations in Tipping Scenario: A Finite Element Study on Several Patients [PDF]

arXiv, 2020
Previous studies on computational modeling of tooth movement in orthodontic treatments are limited to a single model and fail in generalizing the simulation results to other patients. To this end, we consider multiple patients and focus on tooth movement variations under the identical load and boundary conditions both for intra- and inter-patient ...

ToothInpaintor: Tooth Inpainting from Partial 3D Dental Model and 2D Panoramic Image [PDF]

arXiv, 2022
In orthodontic treatment, a full tooth model consisting of both the crown and root is indispensable in making the treatment plan. However, acquiring tooth root information to obtain the full tooth model from CBCT images is sometimes restricted due to the massive radiation of CBCT scanning. Thus, reconstructing the full tooth shape from the ready-to-use

Tooth morphometry using quasi-conformal theory [PDF]

Pattern Recognition 99, 107064 (2020), 2019
Shape analysis is important in anthropology, bioarchaeology and forensic science for interpreting useful information from human remains. In particular, teeth are morphologically stable and hence well-suited for shape analysis. In this work, we propose a framework for tooth morphometry using quasi-conformal theory.

Ammonia-Net: A Multi-task Joint Learning Model for Multi-class Segmentation and Classification in Tooth-marked Tongue Diagnosis [PDF]

arXiv, 2023
In Traditional Chinese Medicine, the tooth marks on the tongue, stemming from prolonged dental pressure, serve as a crucial indicator for assessing qi (yang) deficiency, which is intrinsically linked to visceral health. Manual diagnosis of tooth-marked tongue solely relies on experience.
