Turner tooth

from Wikipedia, the free encyclopedia

The Turner tooth is a malformed permanent tooth with enamel hypoplasia, a malformed crown and / or root, in particular of the incisors and premolars . By apical or intrafurkale milk tooth periodontitis may cause damage to the replacement tooth germ. The Turner tooth is named after the first person to describe it, the English dentist JG Turner (1912) - Turner's tooth (hypoplasia) .

etiology

The cause is usually an ulcerated milk tooth that has been damaged by tooth decay or trauma . Subsequently, an infection developed , which led to the deformity of the tooth after the infection had damaged the tooth germ and the tooth development was defective as a result. Turner's tooth occurs in about a quarter of the cases in which pus foci have developed on the milk tooth root .

Due to the infectious and inflammatory process on the milk tooth, damage to the tooth germ is possible after the bone lamella that surrounds the developing tooth germ has dissolved. The tooth germ can be damaged indirectly, through the pressure resulting from the formation of edema , or directly through the osteolytic process.

Differential diagnosis

Prevention

In order to avoid tooth germ damage, which can lead to a Turner tooth, endodontic treatment or, alternatively, extraction of the milk tooth should be carried out in good time .

Symptoms

Clinically, there are limited white to brownish opaque areas and hypoplasia with defect formation. The defects can range from enamel and dentine defects to malformations of the anatomical crown shape.

therapy

The malformations can usually be corrected with composite tooth abutments . In more severe cases, crowning the tooth is an option.
