[Morphological research on the dental pulp of the calf].
Morphological researches have been carried out through histological studies with fine and semifine sections at the electronic scan microscope on the dental pulp of calves. The general aim was to identify the antioxidant properties of pulp and study cellular density and microfibrillar architecture. The dental pulps of calves of 5-6 months taken immediately after slaughtering were used with immersions into the fixing liquid. The scan microscope showed fibroblasts in the deepest regions of the pulp in a stroma of collagenic fibres, not organised but scattered among the cells of the connective tissue. The odontoblasts presented well ordered one beside the others with well visible details such as the swollen basal portion, the nucleus and a very tight villosity. No clear interodontoblastic connections were evident. The electron transmission microscope revealed typical cells with histiocyte appearance with microfilaments evident in the cytoplasma (myofibroblasts) presenting a wide variety of cytoplasmatic interconnections with interdigitations.
