Histological structure of the double tooth pulp

Introduction. Dental pulp is the remnants of the dental
papilla. It fills the pulp chamber and is attached to
periodontium through the apical foramen of a root.
Double tooth is a disorder related to the increase
in the size of a tooth. Aim of the study. To compare
histological structure of the pulp of a lower third
molar possessing the features of a double tooth with
the histological structure of lower third molars with
no dental caries. Material and methods. Histological
examination of the pulp isolated from eleven lower
third molars was performed. All teeth involved in the
study were not carious and they were extracted in
total. One tooth revealed the features of a geminated
tooth. The remaining ten teeth displayed a typical
anatomical structure. Having prepared the pulp
isolated from the examined teeth, staining of the
scraps with hematoxylin and eosin (H+E) was done
allowing precise imaging of both cellular and tissue
architectonics of the collected research material.
Results. The analysed scraps revealed normal
architectonics of dental pulp. In the peripheral part of
the pulp oblong osteoblasts were identified. Cytoplasm
of osteoblasts stained light pink and oval cell nuclei of
odontoblasts stained basophilic. Poorly differentiated,
acellular layer of the connective tissue forming cellfree
zone of Weil was observed under the layer of
odontoblasts. Conclusion. In the pulp of a double
tooth a larger number of blood vessels was observed.
The pulp of a double tooth revealed normal structure,
with no inflammations. It is difficult to obtain the pulp
