A Review on COVID-19 Mediated Impacts and Risk Mitigation Strategies for Dental Health Professionals

Identification of key risk areas and failure modes using the FMEA method for the prevention and control of major infectious diseases in a stomatology department

PURPOSE

To perform risk assessment and analysis of potential infection during stomatology workflow in a hospital in the context of a major infectious disease outbreak, and to determine the key failure modes and measures to prevent and control infection.

METHOD

Following the Failure Modes and Effects Analysis (FMEA) method based on the stomatology workflow, the opinions of 30 domain-experts in related fields were collected through questionnaires to determine all potential failure modes in the severity (S), occurrence (O), and detectability (D) dimensions. The group score was then integrated through the median method and the risk priority number (RPN) was obtained. Finally, combined with expert experience, a score above 100 was considered to define a key potential failure mode. The data collection period for this study was from August to September 2023.

RESULTS

The key failure modes identified were "Patient concealed epidemiological history (A110) (RPN: 149.6; Rank: 1)," "At the pre-examination door, safe distancing cannot be practiced due to the large number of visitors (A120) (RPN: 147; Rank: 2)," "The patient does not cooperate in checking the health code or itinerary code (A18) (RPN: 128, Rank: 3)," "The patient provides a non-personal health code or itinerary code (A19) (RPN:121.5; Rank: 4)," "Pre-examination personnel did not strictly implement the inquiry of epidemiological history (A12) (RPN: 120; Rank: 5)," and "The patient did not wear a mask according to the specification (A111) (RPN:108.0; Rank: 6)". The key risk area was "Before diagnosis and treatment (A)".

CONCLUSION

Insufficient records of patient epidemiological history may increase the spread of COVID-19 in the oral diagnosis and treatment environment. High-density areas where patients gather are prone to become sources of infection. Finally, improper use of personal protective equipment increases the risk of cross-infection with COVID-19. However, in the face of the potential spread of major infectious diseases in the future, the government and hospitals need to build a more comprehensive epidemiological notification system to provide the population with early action trajectories and warning reports.

Disasters in pediatric dentistry: a systematic review

BACKGROUND

Disasters can harm many people, especially children, in unpredictable and public ways. One of the neglected aspects of children's health in disasters is oral and dental hygiene, which can affect their physical and mental well-being. This systematic review explores how dentistry can help children in disasters, focusing on two aspects: providing oral health care and identifying disaster victims.

METHODS

A thorough search of databases, such as PubMed, Cochrane Library, Scopus, Embase, ProQuest, and Web of Science, was done to find English-language publications from 1930 to August 31, 2023. The screening, data collection, and quality assessment followed the PRISMA guidelines.

RESULTS

Out of 37,795 articles found in the databases, seven research articles were chosen. Five articles were retrospective, and two articles were prospective. The results showed that dentistry for children is very important in disasters by giving information about the oral and dental problems and identifying the victims. The results also showed some of the challenges and difficulties in giving dental care for children in disaster situations, such as changing control, referral systems, and parental fear of infection.

CONCLUSION

Dentistry for children can improve the health and well-being of children affected by disasters.

Evaluating the Dental Hygienists' Exposure to the Risk of Musculoskeletal Disorders

OBJECTIVES

 The aim of the study was to evaluate dental hygienists' exposure to the risk of musculoskeletal disorders (MSDs), by the worksheets compatible with the Rapid Entire Body Assessment (REBA).

MATERIALS AND METHODS

 The research included 272 dental hygienists aged 23 to 52 years from the two administrative regions of Poland.

STATISTICAL ANALYSIS

 STATISTICA 12 and Microsoft Excel were used to analyse the results. The level of significance was p<0.05. The normality of the distribution was tested with the Shapiro-Wilk test. The relationships between the variables were assessed with the χ2 test. Due to the lack of "normality" of the REBA risk distribution, the Mann-Whitney test was used to verify the hypotheses.

RESULTS

 Overall, 48.5% of the examined showed a neck flexion >20, torsion of 80.1%, and 37.5% declared the presence of both types of loads. Also, 14.3% of the examined kept a vertical position, 53.7% flexion to the torso up to 20degrees, 31.4% to 60degrees, and 2.1% to >60degrees. Further, 78.3% of people indicated that they twist the torso. Then, 7% marked the low load's arms position, 45.6% marked the range from 20 to 45degrees, and 39.7% marked the range from 45 to 90degrees. Over 55% showed additional load related to the raising or abduction of the shoulders. Overall, 43% showed a wrong position of forearms. Also, 62.9% showed wrists flexed <15° and the rest showed >15degrees. Again, 79% showed additional twisting and flexion of the wrists. Almost 75% of the examined are exposed to overloads associated with the static load. The examined are not exposed to excessive loads resulting from sudden exertion. REBA scores indicate that the negligible MSDs risk concerns 0.7% examined; low risk, 5.5%; medium risk, 33,1%; high risk, 49.3%; and very high risk, 11.4%. The correlation coeffcients analysis showed that exposure risk is strongly correlated with the overloads on the tested parts of the body in both groups.

CONCLUSION

 The levels of MSDs risk indicate that hygienists more often should be subjected to periodic check-ups in the workplace. They also need ergonomic interventions (education, preventive technique, physical activity, and improvement of the working environment) and modifications of hygienist's college programs in the field of work ergonomics can be also considered.

Pandemic Preparedness and Response: A Foldable Tent to Safely Remove Contaminated Dental Aerosols—Clinical Study and Patient Experience

The D-DART (Droplet and Aerosol Reducing Tent) is a foldable design that can be attached to the dental chair to prevent the spread of contaminated dental aerosols. The objective of this study was to evaluate the ability of the D-DART to reduce spread of aerosols generated during dental treatment. Thirty-two patients (sixteen per group) undergoing deep ultrasonic scaling were recruited and randomly allocated to groups D-DART or Control (no D-DART). After 20 min from the start of the treatment, the clinician’s face shield and dental chair light were swabbed and the viable microbial load was quantified (ATP bioluminescence analysis, blinded operator). Statistical analyses were performed with Tukey’s Honest Test with a level of significance pre-set at 5%. There were significant increases in ATP values obtained from the operator’s face shield and dental chair light for the Control compared with baseline (31.3 ± 8.5 and fold increase). There was no significant change in microbial load when the D-DART was used compared with baseline (1.5 ± 0.4 fold increase). The D-DART contained and prevented the spread of aerosols generated during deep scaling procedures.

A multi-country survey on the impact of COVID-19 on dental practice and dentists' feelings in Latin America

BACKGROUND

The COVID-19 pandemic has significantly influenced the routine of healthcare workers. This study investigated the impact of the pandemic on dental practice and dentists' feelings in Latin America.

METHODS

A survey was conducted with dentists from 11 Spanish-speaking Latin American countries in September-December 2020. Professionals were invited by email and via an open campaign promoted on social media. The questions investigated dental care routines, practice changes, and feelings about the pandemic. Descriptive statistics were used to identify frequencies and distributions of variables. Proportions were compared using chi-square tests.

RESULTS

A total of 2127 responses were collected from a sample with diverse demographic, sex, work, and education characteristics. The impact of COVID-19 was considered high/very high by 60% of respondents. The volume of patients assisted weekly was lower compared with the pre-pandemic period (mean reduction = 14 ± 15 patients). A high rate of fear to contracting the COVID-19 at work was observed (85%); 4.9% of participants had a positive COVID-19 test. The main professional challenges faced by respondents were reduction in the number of patients or financial gain (35%), fear of contracting COVID-19 (34%), and burden with or difficulty in purchasing new personal protective equipment (22%). The fear to contracting COVID-19 was influenced by the number of weekly appointments. A positive test by the dentists was associated with their reports of having assisted COVID-19 patients. The most cited feelings about the pandemic were uncertainty, fear, worry, anxiety, and stress. Negative feelings were more prevalent for professionals who did not receive training for COVID-19 preventive measures and those reporting higher levels of fear to contract the disease.

CONCLUSION

This multi-country survey indicated a high impact of the pandemic on dental care routines in Latin America. A massive prevalence of bad feelings was associated with the pandemic.

Anxiety Levels among Polish and Turkish Dentists during the COVID-19 Pandemic

Working conditions, work-related stressors and high risk of infection, as well as the fear of contagion and spreading the disease to family members, may have influenced dentists' mental health during the COVID-19 pandemic. The aim of this study was to evaluate the anxiety levels among Polish and Turkish dentists during the COVID-19 pandemic and to investigate any relevant predictors. The study was an anonymous online questionnaire-based cross-sectional study that was conducted among dentists from two countries: Poland and Turkey. In total 400 dentists (200 from each country) participated in the study. The survey consisted of two parts: part 1 comprised demographic data, including age, gender, country of origin, COVID-19 infection history, place of work and lockdown history; part 2 was based on the State-Trait Anxiety Inventory (STAI). The mean trait and state anxiety levels of the Polish dentists was statistically significantly lower than that of the Turkish dentists (p = 0.000; p < 0.05). However, Polish dentists had higher state anxiety levels than trait levels, while both types of anxiety among Turkish dentists were almost at the same level. The number of dentists who suffered from COVID-19 was found to be statistically significantly higher in Poland (54%) than in Turkey (16%) (p = 0.000; p < 0.05). The percentage of dentists reporting anxiety was 51% in Poland and 95.5% in Turkey. Polish dentists reported a lower mean anxiety level during the COVID-19 pandemic than the dentists in Turkey but their anxiety levels were more affected by the COVID-19 pandemic as they had a higher difference between their state and trait anxiety levels. The higher coronavirus infection rate and lack of governmental lockdowns of dental practices during the pandemic in Poland compared with those in Turkey may explain the difference in the state and trait anxiety levels.

Influencing Factors of Mental Health Status of Dentists Under COVID-19 Epidemic

OBJECTIVE

To investigate dentists' psychological status and influencing factors in Shaanxi Province during the COVID-19 epidemic and assess their perceived wellness.

METHODS

The study was conducted among dentists from Shaanxi Province in China. The basic information was collected through the network questionnaire star platform. Depression, Anxiety, and Stress Scales (DASS-42) and Perceived Wellness Survey (PWS) were used to assess subjects' psychological status and perceived wellness. Univariate linear regression analysis and multivariate analysis were performed on the influencing factors of depression, anxiety, and stress, and t-test and analysis of variance were used to analyze the perceived wellness results.

RESULTS

The results demonstrated that 33.2% of the surveyed dentists were in a state of depression, 37.1% were anxious, and 34.4% reported stress among 256 subjects. Linear Regression analysis results showed that: "years of working," "the impact of COVID-19 on their life, work, and sleep," "worrying about occupational exposure/virus infection," "lacking the awareness of prevention and control measures," "overtime work during the epidemic," "worrying about participating in the supporting work," and "continuous exhaustion from work" were significant contributors to depression, anxiety, and stress status. In addition, the results of PWS found that each dimension of PWS was correlated with depression, anxiety, and stress state, which indicates the individual's physical and mental health state was associated with multiple factors.

CONCLUSION

COVID-19 has significantly impacted dentists' mental health in Shaanxi Province. With these findings, we aim to educate and promote targeted interventions that can be utilized to improve dentists' mental health by analyzing the influencing factors.

Emotional Health Status of Postgraduate Students of Periodontics in India During COVID Health Crisis-A Questionnaire-Based Study

Dental students, especially postgraduate students present a higher risk of getting infected because of their close contact with the patients during this pandemic. The objectives of the study include (a) the reasons for postgraduate students’ altered emotional status during coronavirus (COVID-19) infection. (b) To assess the kind of infection protocols adopted. (c) To assess the impacts of postgraduate students’ emotional status on treating patients with periodontal problems during the COVID-19 lockdown period from March 2020 to December 2020. The emotional status of postgraduate students was assessed in 2 phases that are at the initial phase of COVID infection and lockdown and the second phase when the lockdown was prolonged. Questionnaires were distributed to the Postgraduate students of periodontics all over India to assess their level of awareness of COVID infection, type of infection control measures followed during the pandemic period, as well as the outpatient turnout during the lockdown period. Results of this study stated that more than 80% of students addressed the decline in the number of patients to surgical clinics, 76.3% of postgraduates were worried about themselves and their families due to the pandemic situation. Surprisingly, 74.3% of them even worried about losing their expertize or skills due to a long lockdown period. Dental postgraduates all over India are willing to treat their patients during the period of a pandemic but in strict compliance with infection control guidelines. This study assessed the emotional responses of the postgraduates during the pandemic through the questionnaire and concluded that all the professionals are ready to resume their clinical activities with adequate guidelines provided.

Impact of the coronavirus disease 2019 pandemic on periodontal practice: A questionnaire survey

Aim

This cross‐sectional study sought to investigate the factors possibly related to the impact caused by the coronavirus disease 2019 pandemic in the practice of periodontists, in two countries.

Materials and methods

A total of 254 periodontists with active periodontics licensing in Brazil and the United States participated in the survey. Data were collected through an online questionnaire and the dependent variable was the perceived impact of the pandemic on periodontists' practice routines. Odds ratios were assessed by logistic regression analysis.

Results

Periodontists in private practice were 83% less likely to report a significant impact of the pandemic on their clinical routine as compared with professionals who work in the public sector or in academic institutions (CI 95%: 0.05–0.47). The financial impact of the pandemic was significantly associated with a perceived severe impact of the pandemic on their routines (OR: 1.36; CI 95%: 1.16–1.61). Professionals who have enhanced their hand‐washing routine were more likely to report a significant impact of the pandemic by 3.41 times (CI 95%: 1.28–9.04) relative to those who have not altered their hand‐washing protocols.

Conclusion

The pandemic is associated with a negative impact on the practice of periodontists, especially those working in public sectors and academic institutions.
