Familial autosomal dominant severe ankyloglossia with tooth abnormalities

American Journal of Medical Genetics Part A, 2018
Ankyloglossia is a congenital oral anomaly characterized by the presence of a hypertrophic and short lingual frenulum. Mutations in the gene encoding the transcription factor TBX22 have been involved in isolated ankyloglossia and X‐linked cleft palate. The knockout of Lgr5 in mice results in ankyloglossia.

Initial observations of cheek tooth abnormalities in sheep in Slovenia

Veterinary Record, 2010
Observations were made on a small flock of 50 sheep of the native Slovenian Jezersko‐Solcava breed by investigators with dental training. The aim was to determine the range of naturally occurring dental diseases, so postmortem examinations were performed on animals slaughtered for meat or culled due to disease.

Identification of Tooth Abnormalities Using Terahertz Imaging and Spectroscopy

Diagnostic Optical Spectroscopy in Biomedicine II, 2003
Terahertz (THz) frequency spectroscopic imaging studies of teeth are reported. The aim is to establish the characteristic spectroscopic properties of the enamel and dentine at these high frequencies. Changes to the THz characteristics as a result of various types of tooth decay are reported showing the potential of this technique for dental diagnosis.

DBGANet: Dual-Branch Geometric Attention Network for Accurate 3D Tooth Segmentation

IEEE transactions on circuits and systems for video technology (Print)
Accurate segmentation of 3D dental models derived from intra-oral scanners (IOS) is one of the key steps in many digital dental applications such as orthodontics and implants. However, it is difficult to accurately segment individual teeth and gums in 3D

Relationship between Tooth Loss and Electrocardiographic Abnormalities in Octogenarians

Journal of Dental Research, 2001
Recent reports have suggested that periodontal disease is a risk factor for coronary heart disease (CHD). However, little is known about the relationship between periodontal disease and CHD in the very elderly. Therefore, we evaluated the association between tooth loss and abnormal ECG findings in octogenarians.
