[Radiological estimation of interradicular space of primary molar teeth].

Radiological estimation of interradicular space of primary molar teeth has been performed. Radiograms taken from the department's archives on which primary molar teeth without dental caries were visible have been used for the purposes of the examinations. Roentgenograms had been made for exposition conditions required for endodontic therapy needs. Periodontium, lamina dura of the alveolus, bone texture of the interradicular space and disposition of permanent tooth buds have been estimated according to the radiograms. From the examination results it followed that proper estimation of interradicular space of primary molar teeth according to radiograms made for endodontic therapy needs is not possible. Radiological image of interradicular space of primary molar teeth in various both with reference to bone structure and disposition of permanent tooth buds. In most cases the interradicular space of primary molar teeth demonstrates thin bone structure on radiograms that should be considered to be physiological state when the continuity of lamina dura of the alveolus is preserved.
