This study will identify anatomical conditions that are at high risk for the development of hypersensitivity (association of the wisdom tooth root with the mandibular canal).
Efficacy
Onset of nerve paralysis in each case and the degree of mandibular canal deformity caused by the root of the wisdom tooth and whether it is caused by the position of the wisdom tooth root and mandibular canal (buccal, lingual, subapical, and interdental canal).
Observational
| 20 | years-old | <= |
| Not applicable |
Male and Female
(i) Cases with mandibular wisdom teeth extracted at the study institution between April 1, 2018 and March 31, 2021.
(ii) Cases that are 20 years of age or older.
(1) Cases in which sufficient information cannot be obtained due to poor entries in the medical information record.
(2) Cases in which a CT scan was not taken before surgery.
(3) Cases in which a cyst or tumor exists with the wisdom tooth and is in contact with the mandibular canal.
(4) Cases in which patients developed hypersensitivity prior to extraction of the wisdom tooth.
