Abnormalities of tooth development in pituitary dwarfism

Oral Surgery, Oral Medicine, Oral Pathology, 1977
Roentgenographic studies of the jaws and teeth in a group of forty-eight pituitary dwarfs showed the following abnormalities in the development of the teeth: 1. Delayed shedding of the deciduous teeth. 2. Absence of resorption of the roots of the deciduous teeth at the usual time. 3. Marked delay in eruption of the permanent teeth. 4.

Human Diseases Associated with Abnormal Tooth Roots

Journal of Oral Biosciences, 2009
Abstract Tooth development is a complicated process, characterized by reciprocal interactions between the dental epithelia and mesenchyme. During this process, inner and outer enamel epithelia form a doublelayered sheath, Hertwig's epithelial root sheath, after crown formation. A close association has been suggested between this root sheath (epithelia)

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.

Hip Abnormalities in Children With Charcot-Marie-Tooth Disease

Journal of Pediatric Orthopaedics, 1994
Hip dysplasia was recently observed in association with Charcot-Marie-Tooth disease (CMT). We retrospectively reviewed available radiographs of 74 of 100 children with clinically and electrodiagnostically proven CMT and noted six cases of hip dysplasia. Minor hip abnormalities, most commonly increased neck shaft angles, were noted in 21 other patients.

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

Abnormal macrophage polarization impedes the healing of diabetes-associated tooth sockets

Bone, 2021
Patients with poorly controlled type 2 diabetes mellitus (T2DM) often experience delayed tooth extraction socket (TES) healing. Delayed healing is often associated with an aberrant inflammatory response orchestrated by either M1 pro-inflammatory or M2 anti-inflammatory macrophages.
