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]
External resorption can be classified into four categories by its clinical and histologic manifestations: external surface resorption, external inflammatory root resorption, replacement resorption, and ankylosis. External inflammatory root resorption can be further categorized into cervical resorption with or without a vital pulp (invasive ...
Feline odontoclastic resorption lesion (FORL) is a syndrome in cats characterized by resorption of the tooth by odontoclasts, cells similar to osteoclasts. FORL has also been called Feline tooth resorption ( TR ), neck lesion , cervical neck lesion , cervical line erosion , feline subgingival resorptive lesion , feline caries , or feline cavity .
In the dental specialty of endodontics, periradicular surgery is surgery to the external root surface. Examples of periradicular surgery include apicoectomy, root resection, repair of root perforation or resorption defects, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures.
For successful treatment of abrasion, the cause first needs to be identified and ceased (e.g. overzealous brushing). Once this has occurred, subsequent treatment may involve the changes in oral hygiene, application of fluoride to reduce sensitivity, or the placement of a restoration to help prevent further loss of tooth structure and aid plaque ...
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.
Despite the treatment provided, dental avulsion carries one of the poorest outcomes with 73–96% of the replanted teeth eventually being lost. [29] There are three main factors which significantly influence the prognosis of the tooth. These include: The extent of damage to the periodontal ligament (PDL) at the time of injury
Visual of tooth decay. Pulpotomy is a minimally invasive procedure performed in children on a primary tooth with extensive caries but without evidence of root pathology. [1] The minimally invasive, endodontic techniques of vital pulp therapy (VPT) are based on improved understanding of the capacity of pulp tissues to heal and regenerate plus the availability of advanced endodontic materials.
