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]
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.
Physiological bone resorption is an integral part of bone functioning, while the bone is constantly growing thanks to two processes — breakdown and formation of bone tissue. [23] Locally, it could be manifested in tooth eruption when the movement of a tooth follicle is followed by an active resorption of jaw bone tissue.
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.
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.
Threshold shift, the reduction in hearing due to reduced sensitivity level of ears due to noise exposure, occurs due to the use of an ultrasonic scaler, and although this is found to last between 16 hours to almost 2 days, it could cause irreversible damage. [50]
Last year, the American Dental Association (ADA) issued a statement warning people about the dangers of veneer techs, stating that “unsupervised dental treatment from unlicensed individuals has ...
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.
