Tooth ankylosis refers to a fusion between a tooth and underlying bony support tissues. In some species, this is a normal process that occurs during the formation or maintenance of the dentition. [1] By contrast, in humans tooth ankylosis is pathological, whereby a fusion between alveolar bone and the cementum of a tooth occurs.
Tooth pathology is any condition of the teeth that can be congenital or acquired. Sometimes a congenital tooth disease is called a tooth abnormality.These are among the most common diseases in humans [1] The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such ...
The most common cause of tooth impaction is lack of space in the mouth for the tooth. [70] Other causes may be tumors, cysts, trauma, and thickened bone or soft tissue. Tooth ankylosis occurs when the tooth has already erupted into the mouth but the cementum or dentin has fused with the alveolar bone. This may cause a person to retain their ...
It is currently believed that the periodontal ligament plays an important role in tooth eruption. The first human teeth to appear, the deciduous (primary) teeth (also known as baby or milk teeth), erupt into the mouth from around 6 months until 2 years of age, in a process known as "teething". These teeth are the only ones in the mouth until a ...
The prevalence is of PFE is about 0.06% in population. In this type of failure, teeth that are non-ankylosed fail to erupt in the mouth. These teeth do not have a precursor tooth that is blocking their path. These teeth tend to erupt partially but then fail to erupt as the time goes on.
This leads to an inflammatory process that causes external root resorption. [16] Alternatively, pressure may also cause external inflammatory root resorption. Specifically, application of heavy, continuous, and intrusive (i.e. directed toward the bone) forces during orthodontic tooth movement are associated with external root resorption. [17]
"Cavities, gum disease and tooth abscess are the most common causes of pain in the mouth developed by bacteria," says Arlene A. Asante, a dentist at First Class Smiles of Bethesda. Cavities can ...
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
