Third molars confusing the diagnosis of carcinoma.

ABSTRACT

The purpose of this study was to describe cases of oral cancer in which the initial presenting symptoms were considered to be due to third molars and in which the underlying carcinoma therefore escaped early diagnosis. Between 1986 and 1990 a total of five cases with squamous cell carcinoma associated with a third molar (impacted, partially or totally erupted, or recently extracted) were treated at our unit. Because of acute or chronic symptoms related to disturbed eruption of third molars, the detection of a simultaneous malignant change and referral were delayed. In conclusion, all third molars, especially impacted, partially erupted, or overerupted ones, should be examined critically, especially if the patient has symptoms.
