Abstract
BACKGROUND: The occurrence of tooth fractures and cracks depends on multiple factors, including the extent of tooth destruction and the type of restoration. However, existing data does not fully assess the probability of these complications under specific clinical conditions. A statistical analysis of fracture risks based on different tooth conditions is needed to improve treatment planning and preventive measures.
AIM: To analyze the detectability and probability of fractures and cracks of teeth, depending on the degree of their destruction and the type of defect replacement.
MATERIALS AND METHODS: During 2024, the FSBI "Clinical Center of Dentistry of the FMBA of Russia" conducted a study of the frequency of detection and circumstances of the development of fractures and cracks in teeth, as well as an analysis of the annual report regarding the volume and structure of services provided in the treatment of caries, its complications and restoration of hard tooth tissues. The probability of fracturing was calculated using a formula that included a specific condition for detecting fractures or cracks, the number of fractures and cracks detected according to a specific condition, and the number of services provided over a similar period of time.
RESULTS: The frequency of detection of fractures and cracked teeth is 8.9%, with a predominant period after completed treatment of 5 years. The calculated probability of these complications with a five-year prognosis varies from 7.8% in vital teeth to 32.8% in devitalized ones. The most likely fractures and cracks are characterized by such dental conditions as an unsupported cavity of more than half of the occlusal surface (44.5%) and the presence of a metal pin in the tooth (52.9%).
CONCLUSION: The obtained indicators of the probability of cracks and fractures in the five-year perspective illustrate the significant provocative role of such conditions as tooth devitalization, support on the tooth of a removable prosthesis, an unsupported cavity in the tooth of more than half of the occlusal surface, and reinforcement of the tooth with a metal pin.
