Wisdom tooth with close association to the inferior alveolar nerve. When extracting lower wisdom teeth , coronectomy is a treatment option involving removing the crown of the lower wisdom tooth, whilst keeping the roots in place in healthy patients.
Severe tooth decay or infection (acute or chronic alveolar abscess, such as periapical abscess – collection of infected material [pus] forming at the tip of the root of a tooth). [6] Despite the reduction in worldwide prevalence of dental caries , it is still the most common reason for extraction of (non- third molar ) teeth, accounting for ...
Dental abscess; Other names: Dentoalveolar abscess, periapical abscess, tooth abscess, root abscess: A decayed, broken down tooth, which has undergone pulpal necrosis. A periapical abscess (i.e. around the apex of the tooth root) has then formed and pus is draining into the mouth via an intraoral sinus . Specialty: Dentistry
Dental crowns, tooth extraction, gum surgery Resorption of the root of the tooth , or root resorption , is the progressive loss of dentin and cementum by the action of odontoclasts . [ 4 ] Root resorption is a normal physiological process that occurs in the exfoliation of the primary dentition .
A tooth with extensive caries eventually requiring extraction. In certain cases, endodontic therapy may be necessary for the restoration of a tooth. [143] Endodontic therapy, also known as a "root canal", is recommended if the pulp in a tooth dies from infection by decay-causing bacteria or from trauma.
Tooth #5, the upper right second premolar, after extraction. The two single-headed arrows point to the CEJ, which is the line separating the crown (in this case, heavily decayed) and the roots. The double headed arrow (bottom right) shows the extent of the abscess that surrounds the apex of the palatal root.
A phoenix abscess is an acute exacerbation of a chronic periapical lesion. It is a dental abscess that can occur immediately following root canal treatment . Another cause is due to untreated necrotic pulp (chronic apical periodontitis). [ 1 ]
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.
