Between 2.3% and 38.3% of roots loosen during the procedure and need to be removed and up to 4.9% of cases require reoperation due to persistent pain, root exposure or persistent infection. The roots have also been reported to migrate in 13.2% to 85.9% of cases.
Inflamed alveolar bone, unprotected and exposed to the oral environment after tooth extraction, can become packed with food and debris. Dry-socket typically causes a sharp and sudden increase in pain commencing 2–5 days following the extraction of a mandibular molar, most commonly the third molar. [51]
The upper teeth are denoted I 1, I 2, C −, Pm 3, Pm 4, M 1, M 2, and M 3. Left or right has to be specified. The lower teeth are I 1, I 2, C −, Pm 3, Pm 4, M 1, M 2, and M 3. The reason the premolars are labeled 3 and 4 is that in earlier primates there were two other premolars between them and the canines. [5]
Most of the rest of the world uses the FDI World Dental Federation notation, accepted as an international standard by the International Standards Organization as ISO 3950. [3] However, dentists in the United Kingdom commonly still use the older Palmer notation despite the difficulty in representing its graphical components in computerized (non ...
Under the FDI notational system, the right and left maxillary third molars are numbered 18 and 28, respectively, and the right and left mandibular third molars are numbered 48 and 38. [15] According to the Universal Numbering System the right and left upper wisdom teeth are numbered 1 and 16 and the right and left lower wisdom teeth are 17 and ...

The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
Suggested characteristics are: 1) 10-20° of occlusal convergence, 2) minimum height of 4 mm for molars and 3 mm for other teeth, 3) a height:width ratio of 0.4 or greater, and 4) proximal line angles should be conserved. When these characteristics are lacking, auxiliary retention (e.g. axial grooves) are needed. [4]
