Was the Coronavirus Disease 2019 Pandemic Associated with an Increased Rate of Cracked Teeth?

INTRODUCTION: There is lack of data on whether the coronavirus disease 2019 (COVID-19) pandemic was associated with changes in the etiology of pathosis in endodontic patients. The aim of this study was to determine the rate of cracks and other etiologic factors during the period of March 16th to May 31st in 2020 (COVID-19 initial outbreak) and 2021 (COVID-19 ongoing pandemic) compared with figures from the same period in 2019 (pre-COVID era) in 2 endodontists' practices. METHODS: The etiologies of patients' chief complaints were determined from records of 2440 teeth (740 in 2019, 651 in 2020, and 1049 in 2021). Changes in the proportion of etiologic factors among all 3 periods were analyzed. The association between the rate of cracked teeth and patients' age and sex was determined using a logistic regression model. RESULTS: The rates of all etiologies collectively during the studied periods showed a significant change (P < .0001). The rate of cracks significantly increased in 2020 (11.8%) (P = .0001) and 2021 (8%) (P = .0018) compared with 2019 (4.3%). The rate of persistent infections decreased in 2020 (22.3%) (P = .0013) and then increased in 2021 (27.5%) (P = .0153) compared with 2019 (30%). Cracked teeth were associated with the age group of 40-60 years (odds ratio [OR] = 1.882; 95% confidence interval [CI], 1.063-3.330) in 2020 and with age ranges of 40-60 years (OR = 2.051; 95% CI, 1.120-3.759) and >60 years (OR = 2.038; 95% CI, 1.050-3.956) and male sex (OR = 1.599; 95% CI, 1.019-2.510) in 2021. CONCLUSIONS: The rate of cracked teeth increased during the initial outbreak of the COVID-19 pandemic and 1 year later. This study provided evidence on the association between the COVID-19 pandemic and changes in the rate and presentation of endodontic etiologic factors.

Financial Impact of COVID-19 Pandemic on Endodontic Clinics in Egypt: A Questionnaire-Based Report.

OBJECTIVE: To evaluate the financial impact of the COVID-19 pandemic on endodontic clinics in Egypt. METHODS: Two hundred Egyptian endodontists holding a minimum of a master's degree were invited to participate in an online survey in March 2021. Participants accessed the survey link shared on the social media group of the Egyptian Society of Endodontology. Participants read and signed an electronic informed consent before participating in this study. The questionnaire was designed exclusively by the authors. A draft was pilot tested on a sample of 15 endodontic masters' students at The British University in Egypt. Suggestions and comments to improve clarity, content, and validity were incorporated into the revised survey. The questionnaire was divided into five sections; the first section comprised of questions about the participants' demographic details. The second section targeted the current and future financial impact of COVID-19 on practices. The third section included information about the average patient flow and the introduction of teledentistry in clinical practice. The fourth section assessed the effect of COVID-19 on the staff in the dental clinics and the changes made in response to COVID-19. The last section estimated COVID-19 prevalence among endodontists and staff. Categorical data were presented as frequencies (n) and percentages (%) and were analysed using Fisher's exact test. Quantitative data were presented as mean and standard deviation values. P-values were adjusted for multiple comparisons utilising Bonferroni correction. RESULTS: A total of 141 endodontists participated in the survey. The negative financial impact of COVID-19 was reported by 84.39% of the participants. Seventy-eight endodontists (55.3%) suffered from the increased cost of endodontic materials. Of the endodontist respondents, 90.8% suffered from the increased cost of PPE, 82.3% did not charge their patients more, and only 14.4% planned to charge more. A decrease in the number of referred cases for endodontic treatment has been noticed by 58.9%. About 47.5% noticed increased patient phone calls replacing patient visits. Only 12.8% have dismissed staff because of financial problems. CONCLUSION: COVID-19 has negatively affected most endodontists financially and significantly affected their practices' strategies.

Recommendations for Managing Endodontic Emergencies during Coronavirus Disease 2019 Outbreak.

INTRODUCTION: The management of endodontic emergencies has been particularly challenging during the coronavirus disease 2019 (COVID-19) outbreak because of the possible generation of airborne particles and aerosols. The aim of this report was to contribute to the practice of endodontics by proposing a general protocol for the management of emergencies showing the rationale for remote diagnosis, clinical procedures, and the use of personal protective equipment and barriers at the dental office during the COVID-19 outbreak. METHODS: A review of the literature was conducted up to May 2020 on relevant institutional sites, aiming to retrieve the best updated evidence. The reporting considered the Reporting Tool for Practice Guidelines in Health Care statement. RESULTS: Recommendations from Cochrane Oral Health, the American Dental Association, and the Centers for Disease Control and Prevention were included along with the American Association of Endodontists resources and scientific articles that addressed the issue. CONCLUSIONS: The proposed protocol could contribute to the management of endodontic emergencies at the dental office during the COVID-19 outbreak.

General Anxiety in Dental Staff and Hemodynamic Changes over Endodontists' Workday during the Coronavirus Disease 2019 Pandemic: A Prospective Longitudinal Study.

INTRODUCTION: The aim of this study was to assess general anxiety levels in endodontists and dental assistants related to different conditions during the pandemic and lockdown and to evaluate hemodynamic changes in endodontists' heart rate (HR), blood pressure, and blood oxygenation during their workday. METHODS: Anxiety levels in endodontists and dental assistants were recorded weekly during the state of alarm declared because of the coronavirus disease 2019 pandemic. Hemodynamic parameters were monitored using a sphygmomanometer for HR and blood pressure and a pulse oximeter for oxygen saturation. Measurements were taken before and after each root canal treatment as well as on arrival at the clinic and at the end of the working day. Rest data, recorded every Saturday, served as a control. Data analysis was performed using chi-square, paired t, Mann-Whitney, and analysis of variance tests (P < .05). RESULTS: General anxiety decreased over the weeks, with significant differences between weeks 1 and 4 (P < .05). Endodontists perceived higher anxiety levels of anxiety during anesthesia inoculation and dental assistants during the dental unit's disinfection and equipment material (P < .05). There was a significant increase in the cardiovascular response in all endodontists in the clinic registrations compared with rest data (P < .05). Values were higher in the strict confinement period and significant for HR when arriving at the clinic (P < .05). CONCLUSIONS: Levels of general anxiety were higher during the first weeks. The chief perceived factors related to anxiety in endodontists and dental assistants were the risk of contagion and protection measures. Higher HR and blood pressure levels were registered during the workday, especially when arriving at the clinic.

Differences in endodontic emergency management by endodontists and general dental practitioners in COVID-19 times.

The aim of this study was to assess the differences, if any, between general dental practitioners (GDPs) and endodontists, in the diagnosis and treatment of endodontic emergencies during the worldwide outbreak of COVID-19. An online questionnaire was randomly sent by social media to clinicians in different countries from 24 April, 2020 to May 4, 2020. The survey consisted of a series of questions about demographic characteristics, endodontic emergency diagnoses, approaches to prevent aerosol formation, drug prescriptions in case of symptomatic irreversible pulpitis, and the ways in which dentists managed endodontic emergencies during the COVID-19 lockdown. A total of 1,058 dentists responded to the questionnaire; 344 (32.6%) of the participants were endodontists. Slightly less than half of the participants (n = 485, 45.8%) worked during the lockdown, but only 303 participants (28.6%) treated endodontic cases/emergencies. The responses showed agreement between endodontists and GDPs regarding the diagnosis of symptomatic irreversible pulpitis (SIP), symptomatic apical periodontitis (SAP), reversible pulpitis, and asymptomatic irreversible pulpitis (AIP). SIP and SAP were considered an emergency, whereas reversible pulpitis and AIP were not considered an emergency (p > 0.05). Non-aerosol-generating procedures and treatment approaches differed between the groups (p < 0.05). One-third of the participants did not use rubber dam (p > 0.05). Ibuprofen and amoxicillin-clavulanic acid were the most frequently prescribed drugs for pain associated with SIP. In conclusion, the most relevant findings in our survey were the differences between endodontists and GDPs in diagnosis, precheck triage, deep caries excavation procedures, and endodontic emergency pain relief strategies.

A Cross-sectional Survey on the Impact of Coronavirus Disease 2019 on the Clinical Practice of Endodontists across the United States.

This survey investigated the effect of the coronavirus disease 2019 (COVID-19) pandemic on the clinical practice of endodontics among the American Association of Endodontists (AAE) members by evaluating the impact on clinical activities, patient screening, infection control measurements, potential transmission, clinical protocols, as well as psychological concerns. A descriptive, cross-sectional survey was developed to query AAE members from all 7 districts. The survey consisted of 24 questions, 8 demographic questions and 16 questions related to the COVID-19 pandemic impact on the clinical practice. A total of 454 AAE members participated in the survey. As of July 2020, most endodontists were active in front-line treatment of dental patients (82%). N95 respirator face mask was described by 83.1% of the participants as special measures beyond the regular personal protective equipment. Rubber dam isolation was recognized by the majority of the participants at some level to reduce the chance of COVID-19 cross infection. Most of the endodontist participants acknowledged trauma followed by swelling, pain, and postoperative complication to be emergencies. The majority of respondents reported being concerned about the effect of COVID-19 on their practice. No differences in worries about COVID-19 infection were related to demographics (P > .05). The majority of the endodontists are aware of the COVID-19 pandemic, are taking special precautions, and are concerned about contracting and spreading the virus. Despite the conflict between their roles as health care providers and family members with the potential risk of exposing their families, most of them remain on duty providing front-line care for dental treatment.

Knowledge about Coronavirus disease 19 (COVID-19) and its professional repercussions among Brazilian endodontists.

The aim of this study was to assess Brazilian endodontists' level of knowledge about the coronavirus disease (COVID-19) and examine its professional repercussions. The link to the online survey that was created for this study was shared with Brazilian endodontists through social networking applications. The questionnaire contained questions that pertained to COVID-19 and its impact on dental practice. The collected data were analyzed using t-test, chi-square analysis, and analysis of variance, and the level of significance was set at 0.05. A total of 2,135 participants responded to the questionnaire, and all five Brazilian regions were represented in the sample. A total of 98.50% of endodontists reported that dental procedures can transmit COVID-19. Complete social distancing was practiced by 96.68% of the participants, and approximately 25% knew someone who had COVID-19. Moreover, in their daily practice, 72.13% of them implemented biosecurity measures that are ineffective in preventing COVID-19. Furthermore, 91.7% of them reportedly suspended elective dental procedures. Only 55.69% of them reported that they performed only emergency procedures in their workplaces. Those who believed that COVID-19 cannot be transmitted during dental procedures were less knowledgeable about the symptoms of COVID-19 (p = 0.0095). Endodontists who believed that personal protective equipment cannot prevent contamination were more knowledgeable about the symptoms of COVID-19 than their counterparts (p = 0.0003). The participating Brazilian endodontists demonstrated adequate knowledge about the risk of contamination during dental procedures and the main symptoms of COVID-19. Only some professionals reported providing emergency dental care during the pandemic.
