Scientists from Sechenov University have developed a device for detecting the pulp, which will prevent damage to the inside of the tooth. This was reported to socialbites.ca in the press service of the university.
The method developed by scientists will help doctors accurately determine the distance to the pulp, the central part of the tooth filled with nerves and blood vessels. This will allow dentists to work only with the outer layers of the tooth, enamel and dentin, in caries treatment.
“In the treatment of caries, it is important to preserve the dental tissues as much as possible and to prevent the opening of the pulp when removing the carious-affected dentin, but modern methods for assessing the thickness of the dentin are laborious and inaccurate. sufficient. They are not widely used in clinical practice, and the doctor has mainly to rely on his own experience. Excessive removal of dentin and opening of the tooth cavity can lead to pulp infection and the development of inflammation, in which case the pulp must be removed and the root canals closed, which significantly increases the time and financial costs of treatment, ”the expert dentist of the institute told the issue of dentistry socialbites.ca. EV Borovsk Sechenov University Anna Turkina.
The new probe, which is less than a millimeter thick, uses the optical method of diffuse reflection spectroscopy, which makes it possible to evaluate the absorption and scattering of light. You can find out where the dentine ends and where the pulp begins with these markings. Scientists have successfully tested the probe on wisdom teeth removed from patients for medical reasons.
“X-rays and other examination methods give a very conditional idea of u200bu200bthe distance to the pulp. Dentin is a translucent tissue, and the pulp contains hemoglobin and water, which can be recorded using diffuse reflection of light. “Our probe can be inserted into the carious cavity during dental intervention to estimate how many millimeters remain in the pulp and determine the end point of the preparation,” said Gleb Budylin, head of the Clinical Biophotonics Laboratory in Sechenov. University, to socialbites.ca.
Now scientists are conducting clinical tests of the probe developed during dental interventions. In the future, the method may enter wide clinical application. The study was carried out within the framework of the “Priority 2030” strategic academic leadership program.
