چکیده
Large calcified areas were observed in the articular discs of the temporomandibular joint from five patients suffering from articular dysfunctions. The calcified regions were always located inside the fibrous tissue of the discs. They had a woven bone-like morphological pattern and consisted of a compact mineralized tissue containing cells in irregular lacunae. In all the samples the calcified tissue was completely surrounded by a mineralizing border rich in cells and variously arranged collagen fibrils. Energy-dispersive spectrometry showed that mineralized regions contained large amounts of Ca and P. X-ray powder diffraction identified the crystals in these areas as hydroxyapatite.

-This study presents a statistical analysis of variability in six measures of enamel prism and ameloblast size and spacing gathered using confocal microscopy, and applies the results to a consideration of appropriate sampling strategies for taxonomic analyses. Variability within individuals was examined within depth series. Individual variability was also assessed within a nested analysis of va...
متن کاملTopographic distribution of bacteria associated with oral malodour on the tongue.
OBJECTIVE To investigate the topographic distribution of bacterial types and loads associated with mid-morning oral malodour on the tongue surface. DESIGN Fifty subjects with good oral health and at least 20 natural uncrowned teeth were included. Samples were taken with sterile brushes from the dorsal anterior (DA), dorsal middle (DM), dorsal posterior (DP), dorsal posterior to the circumvall...

Late-gestation (embryonic day 18; E18) mouse submandibular glands (SMG) comprise a network of large and small ducts that terminate in lumen-containing, presumptive acini (terminal buds) expressing unique, cell membraneassociated embryonic mucin. The objective here was to clone and sequence embryonic low molecular-weight SMG mucin, predict its secondary structure, and begin to investigate its po...
