When at least 3 teeth are affected, it is referred to as multiple idiopathic cervical root resorption. The causes of external cervical root resorption are poorly understood but trauma, periodontal treatment, and/or tooth whitening may be predisposing factors. [16]
Ankylosis of deciduous teeth may rarely occur. The most commonly affected tooth is the mandibular (lower) second deciduous molar. Partial root resorption first occurs and then the tooth fuses to the bone. This prevents normal exfoliation of the deciduous tooth and typically causes impaction of the permanent successor tooth.
A common scenario of dental treatment causing aggravation of tooth mobility is with a new filling or crown which is a fraction of a millimetre too prominent in the bite, which after a few days causes periodontal pain in that tooth and/or the opposing tooth. [30] Orthodontic treatment can cause increased tooth mobility as well.
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.
Patients with removable prostheses should be examined for areas of mucosal irritation. Procedures which are likely to cause direct osseous trauma, e.g. tooth extraction, dental implants, complex restoration, deep root planning, should be avoided in preference of other dental treatments.
The perception of tooth colour is multi-factorial. Reflection and absorption of light by the tooth can be influenced by a number of factors including specular transmission of light through the tooth; specular reflection at the surface; diffuse light reflection at the surface; absorption and scattering of light within the dental tissues; enamel mineral content; enamel thickness; dentine colour ...
Enamel infractions can also be found as a result of iatrogenic damage inadvertently caused by instrumentation during dental treatments. As of 2024, the prevalence of pathology reaches over 90%. In patients aged 20 years, an average of 4 intact teeth with enamel cracks are identified.
A tooth is unsuitable for periradicular surgery if it does not have a good periodontal support or coronal seal. It must have enough structure to support restoration. Filling the root canals of the tooth from the crown (orthograde root canal therapy) should be the first treatment option to resolve inflammation caused by the tooth.
