[The physical end of a so-called sickle-shaped tooth]

The author had the unique opportunity of surgically exposing a socalled sickle-shaped tooth, righting and aligning it with an orthodontic appliance in a patient then aged 6 years and 9 months and extract this tooth 32 years and 7 months later. The history and further evolution of this patient suggest that the development of a socalled sickle-shaped tooth, which this patient no doubt had, need not necessarily involve a traumatic factor. The displacement of such a tooth as well as the curvature of its root, which was still evident in this patient, appeared to have a genetic basis.
