Tooth number abnormality: from bench to bedside [PDF]
AbstractTooth number abnormality is one of the most common dental developmental diseases, which includes both tooth agenesis and supernumerary teeth. Tooth development is regulated by numerous developmental signals, such as the well-known Wnt, BMP, FGF, Shh and Eda pathways, which mediate the ongoing complex interactions between epithelium and ...

Neuroblastoma and tooth abnormalities: A common history? [PDF]
Neuroblastoma, a malignant tumor of the sympathetic nervous system and the most common extracranial solid tumor in childhood, arises from embryonic neural crest cells. Tooth development begins before birth and continues for 12-14 years with the development of the third molar for several years.

Abnormal vascular reflexes in Charcot-Marie-Tooth disease. [PDF]
Vascular reflexes were assessed in 17 adult patients with Charcot-Marie-Tooth disease using the Valsalva manoeuvre, and the pulse rate and systolic blood pressure responses to standing. Six patients showed abnormalities consistent with an autonomic neuropathy.

Tooth Clenching Induces Abnormal Cerebrovascular Responses in Migraineurs [PDF]
Prevalence of masticatory parafunctions, such as tooth clenching and grinding, is higher among migraineurs than non-migraineurs, and masticatory dysfunctions may aggravate migraine. Migraine predisposes to cerebrovascular disturbances, possibly due to impaired autonomic vasoregulation, and sensitization of the trigeminovascular system.

Variation in Premaxillary Tooth Count and a Developmental Abnormality in a Tyrannosaurid Dinosaur [PDF]
Premaxillary tooth count tends to be stable amongst toothed dinosaurs, and most theropods have four teeth in each premaxilla. Only one case of bilaterally asymmetric variation is known in theropod premaxillary dentition, and there is no record of ontogenetic or individual variation in premaxillary tooth count.

Segmented mechanics for traction of impacted maxillary canine: case report with a 3-year follow-up
Young patients are increasingly concerned with smile aesthetics, resulting in the early visit to the dental office. It is of great importance that professionals such as orthodontists, pediatric dentists, and general practitioners are aware of the ...

Tooth Separations and Abnormal Noise on Power-Transmission Gears
Some theoretical analyses and experimental investigations are performed to give a solution to the separation of tooth meshing, which is accompanied with alarming noise or occasionally abnormal noise. Tooth separation occurs at the specific speed defined by the amount of transmission error and tangential load.

Supernumerary Maxillary Canine along with Transposition: A Case Report [PDF]
Introduction: Tooth transposition is considered as the anomaly of tooth position in two adjacent teeth; the most frequent locations include canine and first maxillary premolar.

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