Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, [1] resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging.
Tooth wear is a complex, multi-factorial problem and there is often difficulty identifying a single causative factor. [3] However, tooth wear is often a combination of the above processes. Many clinicians, therefore, make diagnoses such as "tooth wear with a major element of attrition", or "tooth wear with a major element of erosion" to reflect ...
Bruxism is excessive teeth grinding or jaw clenching. It is an oral parafunctional activity; [1] i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common behavior; the global prevalence of bruxism (both sleep and awake) is 22.22%. [2]
Teeth that are affected are primary mandibular molars followed by secondary premolars in the mandible and maxilla, however any teeth may be affected. [6] While no one race is primarily affected, those with conditions that affect bone hormone levels such as Paget's disease and acromegaly are more likely to develop hypercementosis.
In these cases, teeth may lose their weakened enamel shortly after eruption and are highly susceptible to dental caries. Affected teeth are highly sensitive to chemical and thermal irritants, and may also be difficult to obtain anesthesia. The causes of MIH are thought to be similar to those of other forms of enamel hypoplasia, but occur ...
Permanent (adult) teeth are not discoloured, or the discolouration is mild (grey colour). Little or no attrition (tooth wear) is evident. The crown of the teeth may be bulbous and markedly constricted at the cemento-enamel junction (CEJ). Radiographically, evidence of partial pulp obliteration with a "thistle-shaped appearance". [3]
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.
Complications of Sjögren syndrome include ulcers that can develop on the surface of the eyes if the dryness is not treated. These ulcers can then cause more worrying issues such as loss of eyesight and life-long damage. Individuals with Sjögren syndrome have a slightly increased risk of developing non-Hodgkin lymphoma, a type of cancer. Other ...
