Dentine dysplasia type IIにおける歯髄腔形態の表現についての一考察

抄録

The so-called roentgen sign which is used to describe specific X-ray findings can be useful in the interpretation of radiogram. Among many “roentgen signs”, some terms are used without a full understanding of their.
A clinical case which was considered to be dentine dysplasia type II (DD II) was reported and the meaning of the manifestation of abormal pulp cavity was considered.
In an 18-years-old male, radiograms showed the coronal pulp chambers of molars and root canals of all teeth to be constricted. In incisors and premolars, large coronal pulp chambers with multiple pulp stones and narrow root canals were characteristic.
From previous reports on DD II, the terms “thistle-tube” and “flame shape” were employed to be describe the specific manifestation of abnormal pulp cavity. Consultation with dictionaries showed that “thistle-tube” was the same as “funnel-tube”, and that meant the shape of abnormal cornal pulp cavity and root canal. However, we do not agree to using the term “flame shape”.
We must be cautious of the translation of diagnostic terms into Japanese. If there is no proper expression in Japanese, a translation should not be made.
