Cracked Teeth and Vertical Root Fractures in Pandemic Crisis - Retrospective Study.

Abstract

Introduction: Dental fatigue fractures are the result of occlusal overloads occurring because of increased intensity of occlusal forces or decreased resistance of dental hard tissues to habitual occlusal forces. In the COVID-19 pandemic, occlusal stress has increased significantly, and so has the number of dental fractures. The study has the aim to determine if the number of cases of dental fatigue fractures during the pandemic crisis was higher than in the immediately preceding period.

Methodology: The retrospective study was carried out in a private dental clinic, selecting from the case series presented during March 2019-March 2021 the cases of dental fatigue fractures presented for diagnosis and treatment. The data collected from the patients included the reason for the presentation, the dental and medical history, and results from dental examination and radiological data. The statistical analysis was carried out with Microsoft Excel and SPSS software.

Results: The study included 644 patients, 430 women and 214 men, with ages between 25 and 85 years (61±7.4 years). From a total of 2581 visits, 1534 visits were made to 383 patients between March 2019 and March 2020, and 1047 visits were made to 261 patients between March 2020 and March 2021, the number of visits decreasing by 31.75% during the pandemic. During the pandemic, the number of fractured teeth tripled, increasing from 0.53% to 1.53% (p=0.009). The most affected teeth were the maxillary premolars and the permanent first molar, both mandibular and maxillary. In most cases, the indication for treatment was extraction.

Conclusions: The Sars-Cov2 virus pandemic crisis has significantly increased the number of teeth with dental fatigue fractures presented to the dental office for diagnosis and treatment.
