Abstract
Introduction. Dental pulp is the remnants of the dental papilla. It fills pulp chamber and attaches 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. The aim of the study was the comparison of histological structure of the pulp of lower third molar with the features of a double tooth with the histological structure of the 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 as a whole. One tooth revealed the features of a geminated tooth. The remaining 10 teeth had typical anatomical structure. After making preparations of the pulp isolated from 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. Ultrathin scraps were assessed and photodocumentation was done with the use of Tesla BS-500 transmission electron microscope. Results. The analyzed scraps revealed normal architectonics of dental pulp. In the peripheral part of the pulp there were oblong osteoblasts arranged in rows and forming several layers. Cytoplasm of osteoblasts stained light pink and oval cell nuclei of odontoblasts stained basophilic. Poorly differentiated, acellular layer of the connective tissue forming Weil’s zone was observed under the layer of odontoblasts. In the cell-free zone there were fibroblasts as well as mesenchymal cells and blood vessels. Conclusion. In the pulp of a double tooth 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 for histological examinations when extracting the tooth with abnormal structure as the pulp is usually mechanically damaged during the procedure.
