The relationship between COVID-19 and the dental damage stage determined by radiological examination

Abstract

Objective: COVID-19 causes severe complications particularly in respiratory system especially in the elderly and those with poor general health. General and oral health are closely related to the course of such viral diseases. This study aims to reveal the relationship between the Dental Damage Stage (DD Stg) and the severity of COVID-19 disease.

Materials and methods: The study included 137 patients (20-65 years) based on oral examination records and panoramic X-rays of 1516 COVID-19 patients diagnosed through real time PCR tests. DD Stg were determined according to data of Apical Periodontitis Grading Scale, Radiologic Alveolar Bone Loss and Pathophysiological Process of Dental Caries obtained from dental radiological images. DD Stg were determined according to the severity of dental pathology and compared in terms of age, gender, numbers of dental caries (NDC), dental implants (NDI), root canal treatment (NRCT), tooth fillings (NTF), missing teeth (NMT) and hospitalization due to COVID-19 (NHC), presence of chronic disease (CD), and symptom associated with COVID-19 (SAC) RESULTS: Patients in DD Stg 3 had significantly higher age and mortality. CD, NDC and NHC values were higher in DD Stg 2 and 3 than in DD Stg 0 and 1. NHCs were higher in DD Stg 3 than in DD Stg 2. NMTs were higher in DD Stg 3 than other stages. SACs were significantly lower in DD Stg 0 than in DD Stg 1, 2 and 3. NDC, NHC, SAC and CD were effective on DD staging; they were moderately positively related.

Conclusions: The relationship detected between DD stage and the severity and prognosis of viral disease such as COVID-19 was found to be remerkable for extensive studies.
