Case report--Scanora imaging of an unusual unerupted tooth located entirely below the inferior dental canal.

We present an unusual case of an unerupted tooth located beneath the inferior dental canal (IDC) seen as an incidental finding on a dental panoramic radiograph (DPR). An unerupted premolar was identified on the DPR lying horizontally and located entirely below the inferior dental canal in the first and second molar region. The crown was distally orientated and was somewhat demineralised. As this unerupted tooth appeared to have an intimate relationship with the inferior dental canal, which in turn had a close relationship with the distal roots of the lower left first molar, this relationship was investigated further. Spiral tomography using Soredex's Scanora unit was used to obtain three contiguous 2 mm thick cross-sectional images of the area, which showed the separation of the inferior dental canal from both the first molar tooth above and the unerupted premolar. This case highlights the role of Scanora cross-sectional imaging in establishing accurately the relationship between teeth and the inferior dental canal and to document the unusual position of this unerupted tooth.

A new, accurate and fast digital method to predict unerupted tooth size.

The sum of the lower incisor tooth width has been proposed as the best predictor for calculating unerupted canine and premolar mesiodistal tooth sizes. The aims of this study were to develop a new, fast, and accurate computerized method to predict unerupted mesiodistal tooth sizes and to determine which reference tooth or combination of reference teeth was the best predictor for canines and premolars in a Spanish sample. The dental casts of 100 Spanish adolescents with permanent dentition were measured to the nearest 0.05 mm with a two-dimensional computerized system. The goal was to predict unerupted canine and premolar mesiodistal tooth sizes using the sizes of the upper central incisor, upper and lower first molar, or a combination of these as a reference and using a specific mesiodistal tooth-size table. The results showed that the Digital Method proposed was very accurate in predicting unerupted canine and premolar tooth size. The combination of the sums of the permanent upper central incisor and the lower first molar was the best predictor for canines and premolars in this sample. Upper arch teeth were better predicted than lower arch teeth. The upper lateral incisor provided the worst predictions.

[The Unerupted Tooth, a Cause of Pain (Casuistics): (author's transl)].

In view of the remarkable number of cases of gnathogenous headache it is advisable to submit headache patients to a thorough dental and radiological inspection, even in cases of anodontous jaws, in order to identify unerupted teeth. Such an examination with consequent dental or surgical thrapy can in many cases spare lengthy neurological diagnostic or therapeutic procedures, possibly in hospital.
