The Biology Underlying Abnormalities of Tooth Number in Humans [PDF]

Journal of Dental Research, 2017
In past decades, morphologic, molecular, and cellular mechanisms that govern tooth development have been extensively studied. These studies demonstrated that the same signaling pathways regulate development of the primary and successional teeth. Mutations of these pathways lead to abnormalities in tooth development and number, including aberrant tooth

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.

Tooth abnormalities in congenital infiltrating lipomatosis of the face.

Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology, 2013
The aim of this study was to present a literature review and case series report of tooth abnormalities in congenital infiltrating lipomatosis of the face (CIL-F).Four typical cases of CIL-F are presented. Tooth abnormalities in CIL-F documented in the English literature are also reviewed.

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.

Tooth Abnormalities and Occlusal Disorders in Individuals with Frontonasal Dysplasia

The Cleft Palate Craniofacial Journal, 2017
Objective Frontonasal dysplasia is a rare developmental defect of the midface, and little is known about the dental involvement in individuals with this condition. This study investigated tooth abnormalities and occlusal disorders in individuals with frontonasal dysplasia. Design Cross-sectional.

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.

Tooth abnormalities and soft tissue alterations in patients with G/BBB syndrome.

Oral Diseases, 2008
Objective:  The G/BBB syndrome is an X‐linked recessive disorder characterized by eye anomalies, laryngotracheoesophageal cleft, congenital heart disease, genitourinary anomalies and gastrointestinal disorders. Patients may also present cleft lip and palate, high‐arched palate and thin upper lip.

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.
