Background: The variation in mandibular molars’ anatomy is not as rare as it might appear to be. Depending on the location of the additional root found in a mandibular molar, it may be referred to as either radix entomolaris (RE) or radix paramolaris (RP). The aim of the study was to present radiographic appearance of RE and RP and indicate the clinical implications of its presence. Materials and methods: The material consisted of 3,000 panoramic and 300 periapical radiographs of first and second mandibular molars taken in the Department of Dental and Maxillofacial Radiodiagnostics of the Medical University in Lublin which were screened for RE and RP. Results: Among panoramic and periapical radiographs only 14 cases of additional roots were found: 11 teeth with RE/RP in the Polish population and 3 in Taiwanese. Only 2 panoramic radiographs revealed the presence of RE and surprisingly the occurrence was bilateral. Conclusions: Dentists should not be taken by surprise at finding an additional root in mandibular molars. They should be aware of the anatomical diversity of these teeth and know how to recognise possible extra roots during radiograph reading. (Folia Morphol 2014; 73, 4: 449–454)

The aim of the study was to evaluate the physiological developmental changes of male rats’ lumbar vertebrae during the first 22 days after birth. Morphology and mineralisation of lumbar vertebrae were evaluated using double-staining and digital radiography system, which allowed vertebral width and optical density to be determined. Pup weight, crown-rump length, body mass index and vertebral width increased during postnatal period and significantly correlated with their age. Bone mineralisation, as measured by optical density, did not show any significant differences. The complete fusion of the primary ossification centres had a cranio-caudal direction and started on day 19 after parturition but was incomplete by day 22. It could be concluded that, unlike significant age-related increase of vertebral size, mineralisation was only slightly elevated during evaluated postnatal period. The method described is supplementary to alizarin red S staining as it provides both qualitative and quantitative data on mineralisation in a similar manner to micro computed tomography but does not allow 3 dimensional and microarchitecture examination.
