Mouse models of tooth abnormalities

European Journal of Oral Sciences, 2008
Tooth number is abnormal in about 20% of the human population. The most common defect is agenesis of the third molars, followed by loss of the lateral incisors and loss of the second premolars. Tooth loss appears as both a feature of multi‐organ syndromes and as a non‐syndromic isolated character.

Abnormal Bone Morphology in Charcot-Marie-Tooth Disease

Foot & Ankle International, 2021
Background: Although long suspected, it has yet to be shown whether the foot and ankle deformities of Charcot-Marie-Tooth disease (CMT) are generally associated with abnormalities in osseous shape. Computed tomography (CT) was used to quantify morphologic differences of the calcaneus, talus, and navicular in CMT compared with healthy controls. Methods:

Abnormal tooth tissue in human odontodysplasia

Oral Surgery, Oral Medicine, Oral Pathology, 1976
The affected teeth in this case of odontodysplasia exhibited abnormal hypoplastic enamel, abnormal dentin containing extensive interglobular regions and completely lacking a peritubular matrix, and an abnormal irregular tissue consisting of highly calcified and partially fused granules located within the dentin of the tooth tips.

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.

[Globodontia--a new familial tooth abnormality].

Deutsche zahnarztliche Zeitschrift, 1977
A new, congenital anomaly of tooth form transmitted as an autosomal dominant trait was found in a father and two of his three sons. While the incisors appeared unchanged, the posterior teeth have characteristic massive globe-shaped crowns with irregularly arranged, rounded cusps.

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.

Gene mutations and chromosomal abnormalities in syndromes with tooth agenesis

Oral Diseases, 2022
Abstract This study aims to review the pathogenic mechanisms and clinical manifestations in syndromes with tooth agenesis (TA). Online Mendelian Inheritance in Man and PubMed databases were searched for a comprehensive review. Previous publications reported complicated aetiologies of syndromic TA.

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.
