Enamel fractures can vary in severity, ranging from minor cosmetic issues to more significant structural problems. [1] An enamel fracture typically doesn't cause any noticeable symptoms such as tenderness or an increase in mobility. However, if sensitivity and mobility are present, it may indicate an enamel-dentine fracture or a root fracture. [1]
The primary cause of enamel wear in the grooves is the direct mechanical forces applied during chewing, such as vertical pressure and lateral forces as teeth grind or shear food. Particularly in areas where food is more frequently trapped or where contact is poor, the continuous friction between the food and the tooth surface causes abrasion ...
Enamel-dentine fracture is a complete fracture of the tooth enamel and dentine without the exposure of the pulp. Pulp sensibility testing is recommended to confirm pulpal health. Treatment depends on how close the fracture is in relation to the pulp. If a tooth fragment is available, it can be bonded to the tooth.
Trauma to primary teeth occurs most commonly at the age of two to three years, during the development of motor coordination. [7] When primary teeth are injured, the resulting treatment prioritises the safety of the adult tooth, [7] and should avoid any risk of damaging the permanent successors. [8]
A fracture of a tooth can involve the enamel, dentin, and/or pulp, and can be orientated horizontally or vertically. [10]: 24–25 Fractured or cracked teeth can cause pain via several mechanisms, including dentin hypersensitivity, pulpitis (reversible or irreversible), or periodontal pain. Accordingly, there is no single test or combination of ...
Cracked tooth syndrome could be considered a type of dental trauma and also one of the possible causes of dental pain. One definition of cracked tooth syndrome is "a fracture plane of unknown depth and direction passing through tooth structure that, if not already involving, may progress to communicate with the pulp and/or periodontal ligament ...
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.
The frequency for ankylosis to happen in deciduous teeth is far more frequent than that in permanent teeth, with a ratio of about 10 to 1, and the majority of [4] the ankylosed teeth occur in lower teeth, about twice as often as in the upper teeth. [6] Therefore, it is strongly believed that their incidence may be due to different causes.
