Abstract
The selection of an optimal treatment is one of the problems when restoring the defects of dental hard tissues after endodontic treatment. The work aims at studying the percentage ratio of the volume of the coronal portion of the tooth to its crown that will allow us to optimize the determination of the extent of dental hard tissue defect after endodontic treatment as well as to choose the optimal method of treatment.
The objective of the research was to optimize the diagnostic process when treating damaged coronal portion of the tooth after endodontic treatment through the determination of the percentage ratio of the volume of the coronal portion of the tooth to the total volume of tooth crown for different groups of teeth.
Materials and methods. 42 extracted teeth with preserved coronal portions served as the material for our study. The volume of the coronal potion of the tooth as well as the total volume of tooth crown was determined using the method developed by us. Having calculated the ratio of the volume of the coronal portion of the tooth to the volume of tooth crown, we received the volume which is occupied by the coronal cavity of the tooth.
Results. We obtained the percentage ratio of the volume which is occupied by the coronal cavity of the tooth compared to its crown for different groups of teeth.
Conclusions. To estimate the extent of damage to the coronal portion of the tooth after endodontic treatment, it is recommend using the obtained data, namely, in the maxillary and mandibular front teeth, the coronal portion of the tooth occupies up to 10% of tooth crown volume, while in the maxillary and mandibular grinding teeth, the coronal portion of the tooth occupies up to 5% of tooth crown volume.
