The Mask Fitter, a Simple Method to Improve Medical Face Mask Adaptation Using a Customized 3D-Printed Frame during COVID-19: A Survey on Users’ Acceptability in Clinical Dentistry

COVID-19 has deeply impacted clinical strategies in dentistry and the use of surgical masks and respirators has become critical. They should adapt to the person’s facial anatomy, but this is not always easy to achieve. Bellus3D Company proposed to apply their face scan software, used with selected smartphones and tablets, to design and 3D-print a bespoke “Mask Fitter” to improve the sealing of surgical masks and respirators. Twenty dental staff participants were face scanned and a Mask Fitter for FFP2 respirators was designed and 3D-printed. Participants were asked to wear their Mask Fitter over one week and then completed a survey. Questions were asked about wearing comfort, sealing confidence, glasses or loupes fogging, both with and without the Mask Fitter. Dental staff gave positive feedback, with levels of comfort during daily use reported as similar with and without the Mask Fitter; and a higher confidence in achieving a proper seal, ranging from a 10% confidence rating of a proper seal without the Mask Fitter to 75% with the Mask Fitter. Moreover, fogging problems decreased considerably. The tested Mask Fitter device could represent an easy and low-cost procedure to improve the facial adaptation of the FFP2 respirator.

Conservative Approach of Fractured Tooth with 7-Years of Clinical and Radiographical Follow-Up: Case Report

Clinical and radiographical diagnosis is crucial to treat a tooth with transverse root fracture (TRF) due to dental trauma (DT). This paper aimed to report a clinical case of TRF at the cervical third of tooth 21 injured by recurrent DT with 7 years of follow-up. A 7-years old female patient was referred to dental care after the first episode of DT in 2014. Base d on the radiographical examination, splinting of teeth 11 and 21 was performed using resin composite. After 11 months, the splint was removed and the patient was discharged. In 2015, the patient suffered a second DT of the same tooth. The clinical approach was splinting the traumatized tooth using orthodontic wire and resin composite. In 2018, a third episode of DT occurred. Then, the dental staff chose to maintain the splint and evaluate the case in a long-term. In 2021, based on bone tissue condition, dental fragment stability and radiographical follow-up, the splint was removed. The patient remains under regular follow up evaluations. It can be concluded that a conservative approach in cases of TRF, when possible, can preserve biological tissues.

Prevalence of SARS-COV-2 Antibodies in Dental Healthcare Providers

Background: Occupational hazards and risks are a common public health issue, especially when healthcare workers safety is concerned; they are on high risk of catching infections such like COVID-19. The possibility of cross-infection between dental practitioners and patients is significantly higher due to the close exposure of dental staff to patient oral environment. Aim: To assess the prevalence of SARS-COV-2 antibodies in dental workers working in the Peshawar Dental College and Hospital, Peshawar. Study Design: Cross sectional study Place and Duration of Study: Department of Orthodontics, Peshawar Dental College & Hospital, Peshawar from 1st January 2020 to 31st December 2020. Methodology: One hundred and thirty three dental workers were enrolled. The investigation was run to detect immunoglobulin G and M antibodies against the SARS-CoV-2-2. The aspirated aerosol and air was evacuated and dissipated into the atmosphere. Results: Mean age was 29.4±1.4 years and males were dominant 74 (55.6%) and male workers found greater with positive antibodies. The prevalence of SARS-CoV-2 antibodies was 33.0%. Proportionately dental assistants (20.5% vs 16.9%) and ancillary staff (20.5% vs 10.1%) had higher prevalence. Sore throat and body aches were more common in positive antibodies cases while travel history was found significantly associated with it (40.9% vs 25.0%, p-value, 0.05). Conclusion: High frequency of SARS-COV-2 antibodies was found in dental workers showing a high infection rate of COVID-19 in healthcare workers in local settings. Keywords: Dental workers, COVID-19 infection, Antibodies, SARS-COV-2

“Difficult” dental patients: a grounded theory study of dental staff’s experiences

IntroductionThe “difficult” patient is a well-known and potentially negative character in various care contexts.ObjectivesThis study aimed to generate a conceptual framework explaining the main concerns about “difficult” dental patients, and obtain a deeper understanding of their characteristics, how they affect the dental staff and how the staff think and act in order to manage these patients.MethodsTen interviews were conducted with professional dental caregivers, including dentists, dental hygienists, and dental nurses. The audio-recorded interviews were transcribed and analyzed in accordance with the principles of grounded theory.ResultsThe main concern regarding “difficult” dental patients generated a framework of seven descriptive interrelated lower-level categories grounded in the data, subsumed in the core category “balancing subjective difficulties”. The informants perceived the possession of “showing interaction difficulties” and “having bio-psycho-social complexity”, as characteristic features of “difficult” patients, who could further adversely affect the dental staff by “evoking negative emotions and behaviors”, “hampering self-esteem and job satisfaction”, and “impairing life and health in general”. To manage the dental care of these patients, the staff used strategies aimed at “activating internal and external resources” and “creating adaptive treatment relations” with patients.ConclusionsThe dental staff’s meaning of the phenomenon of “difficult” dental patients points to specific characteristics, effects, and handling strategies. The core category captures the contradictory dynamics of characteristics and affects as these concepts seem interrelated to the caregivers’ handling capacity. The dental staff’s possibility of handling the main concern through balancing subjective difficulties depends on contextual conditions regarding time, to bring the patient and/or oneself at the center of attention. This indicates a need for further research regarding dental interactions and studies generalizing the outlook on “difficult” dental patients.

Improving the fit of filtering facepiece respirators.

Aims To assess the effectiveness and acceptability of smartphone customised frame technology to improve the fit of disposable filtering facepiece class 3 (FFP3) respirators for dental staff who previously failed fit testing.Method In total, 20 volunteers who previously failed FFP3 fit testing were recruited to use smartphone technology (Bellus3D FaceApp) to have a 3D-printed bespoke face frame produced for them. They underwent qualitative fit testing with and without the frame with two freely available disposable FFP3 respirator designs (mask A: GVS F31000 Segre folded model; mask B: Valmy Spireor). The order of testing was random. Ease of use of the smartphone technology and the comfort of the frame were determined by questionnaire.Results Fit test passes increased from 5% without the frame to 70% and 95%, respectively, for masks A and B with the frame (p <0.01). Very few participants reported using the technology as difficult (n = 1/20) or the frame uncomfortable (n = 3/20) or difficult to wear (n = 0/20).Conclusion Customised frames produced using smartphone technology improved qualitative fit test pass rates for two commonly available FFP3 respirators. Using smartphone technology for frame design, wearing a frame and frame comfort levels were all acceptable to the majority of participants.

Aerosol Management in Dentistry During the COVID-19 on YouTube

Aim: The novel coronavirus continues to spread around the world despite all efforts. Dental professionals and staff are exposed to high infection risks and have the potential to spread these infections. Web-based portals are widely used in dentistry for obtaining information. YouTube is one of the most popular web platforms provides a wide variety of information, however, concerns are raised regarding the quality of the videos. The purpose of this study is to analyze the content of YouTube videos on aerosol management in dentistry during the COVID-19 pandemic.&#x0D; Materials and Methods: YouTube search was performed using the terms “dental aerosol management and COVID-19”, “dental aerosol control and COVID-19” and “dental aerosol reduction and COVID-19” with the default filter set to ‘‘sort by relevance’’. The first 100 videos for each term were viewed and analyzed by 2 independent research. The Global Quality Scale (GQS) and the video information and quality index (VIQI) INDEX were performed to evaluate video quality. Viewers’ interactions and Viewing Rate index were chosen to evaluate the video popularity and also other parameters (number of views, duration, time since upload, and likes and dislikes, country of origin, source of upload) were evaluated. &#x0D; Results: After the exclusion criteria 57 videos were evaluated. 11 of the 57 videos had excellent quality and flow. It was observed that as the duration increased, the quality of the videos in both evaluation indexes (VIQI-GQS) were increased. There was no significant difference in terms of loading sources for VIQI and GQS index.&#x0D; Discussion and Conclusions: Besides high-quality videos on aerosol management, there were some low-quality videos that may cause spread of misleading information. Healthcare professionals should play a more active role in the educational videos about infection prevention and aerosol management during pandemic on YouTube.

Work-related musculoskeletal disorders among dental staff in Armed Force Hospital in Dhahran, Saudi Arabia.

Work related musculoskeletal disorders' (WMSDs) are the most important public health challenge among dental staff. The objective of study was to ascertain the prevalence and risk factors for work related musculoskeletal disorder among dental staff in Dhahran, Saudi Arabia. It is a cross sectional study and 130 dental staff with at least 1 year of working experience were random selected from Armed Forced Hospital. The self-administered validated and structured Standardized Nordic questionnaire was used. Logistic regression analysis was done to determine the association of risk factors with WMSD. the results of the present study revealed that there was a high incidence of MSDs in neck, shoulder, and lower back pain among dental personnel (72.6%). The common risk factors which contributed to WMSD were more than 5 year of experience (AOR 1.19(1.03-2.82)), Saudi nationality (AOR 4.88 (1.27 - 18.72)), working more than 12 hours (AOR 3.115 (1.258 7.578)) and resident doctors (AOR 1.14 (1.02 - 1.94)). The study conclude work related MSD were common with high rate of incidence among dental staff . There is need to make a policy which will reduce the burden of WMSD among dental staff.

Oral Care Cards as a Support in Daily Oral Care of Frail Older Adults: Experiences and Perceptions of Professionals in Nursing and Dental Care-A Qualitative Study.

Frail older adults often have poor oral health. In Sweden, oral care cards are designed to be used as an interprofessional tool for documenting the oral health status of older adults with extensive care needs and to describe oral care recommendations. The aim of this study was to explore nursing and dental professionals’ experiences and perceptions of oral care cards. Nursing and dental care staff were interviewed in groups or individually. The recorded data were transcribed verbatim and analyzed using qualitative content analysis. A theme emerged: Navigating an oral care responsibility that is not anchored in the nursing and dental care context. The theme was elucidated in three categories: “Accessibility and usefulness”, “Coordination between nursing and dental care”, and “Ethical approach”. The participants perceived a lack of surrounding frameworks and collaboration concerning oral care and the use of oral care cards. An oral care card could ideally facilitate interprofessional and person-centered oral care. However, oral health does not seem to have found its place in the nursing care context. Further research is needed to investigate how oral care cards ought to be developed and designed to support oral health care work.

Insights on selection of undergraduate dental students.

The goal of selection to dental education was to find those with the greatest aptitude for dentistry. Recently, schools have introduced a variety of tools; however, these have often been adopted without appropriate evaluation regarding existing evidence for fairness, reliability or validity. We explore dental admissions staff beliefs about the quality of different selection tools, with the objective of exploring their decision-making in implementing selection practices. This qualitative study is underpinned by a social constructionist epistemology, in which our principal concern is "explicating the processes by which people come to describe, explain or otherwise account for the world (including themselves) in which they live." We conducted individual interviews with 15 of the 16 UK dental admission leads to elicit their views around admissions processes and aims. Data coding and analysis were initially inductive, using thematic analysis. After the themes emerged, we applied a deductive framework of affordances to group themes and then examined these for heuristics. We identified three main themes; "Selection Tool Use," "Widening Participation Practices," and "Professionalising the Admission Lead Role." Admission leads spoke favourably of tools that allowed a "holistic" view of the applicants "potential". Selection tools were favoured if they enabled "Gut feeling". Leads spoke of evaluating candidates, making sure they were "rounded", and "know what dentistry is all about." In justifying the use of elements of their procedure, the use of heuristics was prominent. In order to minimise the potential consequences of poor selection decisions, it is important to acknowledge that dental admission leads are at risk of depending on sub-optimal heuristics to make judgements about effective selection (shaped by previous practices) rather than using more rational decision-making processes based on the extant evidence (regarding the quality of different selection tools). Future research may be usefully informed by the knowledge translation literature to offer solutions for improving selection practices in dental education.

How NHS Tayside dealt with the COVID-19 pandemic within Urgent Dental Care Centres: clinical staff views and experiences.

Introduction Dental staff are considered to be at increased risk of COVID-19 transmission, and national concerns about personal protective equipment (PPE) and staff safety have been widely reported. This study explores the views of staff working in Urgent Dental Care Centres (UDCCs) during the first COVID-19 lockdown.Aims To explore clinical staff views and experiences of PPE and personal safety while working in NHS Tayside's UDCCs during the initial months of the COVID-19 pandemic.Design Cross-sectional questionnaire survey.Materials and methods A questionnaire was emailed to staff working within NHS Tayside UDCCs during the first lockdown. The questions related to PPE, working environment, personal safety and wellbeing. This paper focuses on PPE and personal safety.Results Of the 176 invited to participate, 116 completed the questionnaire. The majority confirmed that they always had access to appropriate PPE and few had concerns about personal safety.Discussion Despite having worked in a high-risk environment throughout the lockdown, staff supporting the Tayside UDCCs felt safe and well-protected. This runs counter to widely reported anxieties about PPE and safety across the UK. Further investigation is required to understand this disparity.Conclusion The results indicate that PPE was adequate, accessible and staff felt protected.

Management of Dental and Orthodontic Practice in the COVID-19 Scenario.

The coronavirus disease-2019 (COVID-19) pandemic due to the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has casted a deep impact on every aspect of the human life all over the world. The healthcare professionals dealing with the patients have been at the greatest risk of exposure. Dental practitioners fall among the highest risk practitioners because of their field of operation being around the oropharyngeal region of patients, as well as due to the risk of generation of aerosols during various dental procedures. There is a continuous urgent need of modifying the dental practice in accordance with the guidelines issued by the health authorities time to time. Meticulously planned approaches, and adequate precautions and modifications need to be introduced into dental practice. The field of orthodontics also demands a high level of practice modification in order to ensure proper infection control for patients, practitioners, and dental staff.

Burnout assessment among academic dental staff during COVID-19: Data from Arab countries.

Purpose/objectiveThis study aimed to identify factors that were associated with high burnout and investigate the prevalence of burnout among academic dental staff during the COVID‐19 pandemic.MethodA cross‐sectional online survey was carried out among academic dentists who are working in multiple dental schools in Arab countries. The Copenhagen Burnout Inventory was used to assess participants’ work‐related burnout. Logistic regression was used to assess the factors that increase the risk of burnout among academic dentists.ResultsOf the 254 participants who took part in the study, 141 were males (55.5%). The average age of the participants in the study was 42.1 years (standard deviation = 10.0). The prevalence of burnout among participants was 44.9% (n = 114). Using a fully adjusted logistic regression model, age (odds ratio [OR] = 1.05, 95% confidence interval [CI]: 1.01–1.09, p = 0.008) and gender (OR = 0.54, 95% CI: 0.31–0.94, p = 0.03) were significant variables associated with high overall burnout. Female individuals had a substantially reduced risk of experiencing high personal burnout than male participants (OR = 0.56, 95% CI: 0.32–0.98, p = 0.043) in the personal burnout subdomain. While in the patient's burnout subdomain, age (OR = 1.04, 95% CI: 1.00–1.08, p = 0.048), type of speciality (OR = 2.44, 95% CI: 1.02–5.83, p = 0.044), and teaching place (OR = 2.49, 95% CI: 1.21–5.11, p = 0.013) were associated with higher burnout.ConclusionThis study concluded that gender and age are characteristics that increase the risk of higher burnout among academic dentists during the COVID‐19 pandemic.

Development and psychometric testing of the intention to engage in children’s healthy weight (iCHeW) guideline scale for dental staff

Statement of problemIn the evaluation of interdisciplinary interventions for childhood overweight and obesity, behavioural determinants can provide valuable insight into the reasons behind lack of adherence, or ineffectiveness of the intervention. Therefore, it is vital to assess the behavioural determinants of staff when evaluating the implementation of such interdisciplinary interventions. This study aimed to develop and psychometrically evaluate the intention to engage in Children’s Healthy Weight guideline (iCHeW) scale, which assesses the behavioural determinants influencing dental staff’s intention to conduct children’s growth assessments. MethodsInitial items were generated based on review of the literature and the dimensions of the integrative model of behavioural prediction (IM). To test this scale, a cross-sectional survey design was undertaken consisting of three phases: (i) face validity; (ii) content validity; and (iii) psychometric evaluation of the iCHeW scale with a national sample of 125 dental staff. ResultsThe 35 items generated for the iCHeW scale were revised following feedback from a reference group. These 35 items were then appraised by an expert panel, yielding 27 items for psychometric testing. Using exploratory factor analysis, a five-factor solution was extracted, which corresponded to the IM domains, with the deletion of two items. Overall, Cronbach’s alpha of the iCHeW scale was 0.95, with the following values for each subscale: (i) attitudes, 0.93; (ii) behavioural constraints, 0.83; (iii) perceived norms, 0.93; (iv) self-efficacy, 0.94; and (v) behavioural intention, 0.95. ConclusionsThe iCHeW scale is valid and reliable for assessing dental staff’s intention to provide routine growth assessments to children and demonstrates potential for use with non-dental staff.

Occupational Differences in Psychological Distress Between Chinese Dentists and Dental Nurses.

BackgroundDoctors and allied health professionals are facing serious mental health issues, which have received widespread attention. This study aimed to explore the occupational differences in psychological distress between Chinese dentists and dental nurses.Materials and MethodsThe data was collected from a cross-sectional study conducted by the Chongqing Stomatological Association. Medical personnel involved in this survey were invited to complete a battery of self-administrated questionnaires, specifically the General Health Questionnaire-12, Maslach Burnout Inventory, and career choice regret scale. Data on demographic characteristics and working conditions were also collected. The results of these questionnaires were analyzed with SPSS (version 23.0). Univariate and multivariable analyzes were conducted to explore the influencing factors.ResultsA total of 3,020 valid questionnaires, including 1,855 dentists and 1,165 dental nurses, were collected from 11 provinces of China. In general, 23.8% of responders exhibited psychological distress. The rate of dentists was 25.7%, and that of dental nurses was 20.8%. The prevalence was 4.9% higher in dentists than in dental nurses (P < 0.05). The multivariable analysis showed that factors associated with psychological distress for dentists were lower income, burnout, high job stress, career-choice regret, and lack of sufficient personal time, and that for dental nurses were age, lower income, longer working hours per week, burnout, high job stress, low job satisfaction, lack of sufficient personal time, and poor medical environment.ConclusionThe prevalence of psychological distress was relatively high among dental medical staff, and dentists showed a higher prevalence than dental nurses. Nurses have more risk factors for psychological distress than dentists. These results indicate that it is necessary to monitor the mental health status of dental medical staff and implement accurate strategies for dentists and dental nurses to promote their physical and mental health.

Occupational Physical Hazards and Safety Practices at Dental Clinics.

Worldwide, dentistry is known as a high-level occupational hazard profession. Dental staff is usually exposed to several types of hazards which include chemical agents, physical, psychological stress, and workplace violence, biological and ergonomics. The objectives of this paper were to assess levels of occupational hazards and evaluate safety practices at dental clinics. At several dental clinics, levels of noise, lighting, and radiation were measured by recommended instruments and the safety practice was evaluated using a validated and reliable questionnaire (during 3 months of 2020). The mean levels of noise ranged between 46.3 and 67.2 dB, while the noise dose percent (noise exposure level) ranged between 60.7 and 77.6 dB. The mean levels of lighting ranged from 236.3 lux in the X-ray room to 1,080.3 lux in the dental laboratory. The mean levels of radiation ranged from 7.8 to 12.1 µrem. The mean levels of the three physical hazards were lower than their permissible levels at all locations. Levels of noise in dental clinic were affected by the change in the work activities, while this factor has no effect on the levels of lighting and radiation except for certain processes. The demographic variables such as gender, specialization, and the average number of patients showed a significant association with physical hazards, safety practices, while there was no significant association with radiation protection.

The impact of covid-19 pandemic on dental practitioner.

Introduction: The coronavirus has so far been spread all over the world and hin-dered all aspects of person's life. This pandemic has adversely affected the profes-sional life as well.Objectives: To assess the impact of epidemic COVID-19 on dental practitioners.Methodology: Dentist were invited to participate in the study through social media/email. 250 dentist who give consent were selected randomly to be included in the study. Participants were assured about anonymity of the personal information and informed consent taken. Data collected by using an online questionnaire and ana-lyze by using SPSS® version 22Results: Majority (80%) dentists were facing financial constraint, 72% dentist agreed that reopening of clinics could result in transmission of virus. More than half of the dentist agreed that watching/listening news of COVID-19 is causing depression and anxiety. Nearly all the dentist revealed that they usually feel symptoms mimicking that of Covid-19.Conclusion: Dentists due to the direct result of overwhelming fear, confusion and anxiety among dental staff, strengthened by the high perception of the risk of COVID- 19 contraction, had a significant reduction in dental clinical practice. The sudden decline in the number of dental procedures and the implementation of a new infection control protocol has caused financial problems for most dentists.&#x0D; Keywords: COVID-19, Pandemic, dental practitioners.

Bacterial contamination on the inner surface of the masks used by clinicians in a dental clinic

Wearing masks has become an essential safety measure during the coronavirus 2019 (COVID-19) pandemic. Especially clinicians in dental clinics should focus on infection control. However, there is currently no data regarding the frequency of replacement of the masks used in hospitals. Hence, it is necessary for dental clinic staff, who deal with many patients in an aerosol-producing environment, to have precise mask-wearing guidelines. The aim of this study was to evaluate the contamination on the inner surface of the masks used by clinicians in dental clinics and provide basic data to describe hospital infection control guidelines in greater detail. For Study I,12 participants were recruited. The experiment was conducted indoors. After wearing the mask, the temperature and the humidity inside the mask were measured at the set time points (immediately after wearing the mask, and 10 min, 30 min, 1 h, 2 h, and 4 h after wearing the mask). During the experiment, talking was not allowed. For Study II, 23 clinicians from dental clinics were recruited. After wearing the mask, the temperature, the humidity and the number of colony-forming units (CFU) inside the mask were measured at the set time points. Finally, 15 samples were selected for the study based on a survey. Bacterial identification was conducted using the 16S rDNA sequencing. The temperature and the humidity inside the mask increased significantly relative to room temperature and room humidity, respectively. Bacteria were found in all the masks worn for more than 10 min and the CFU values increased with the mask-wearing time. Bacteria belonging to the genera Staphylococcus, Bacillus and Roseomonas were detected in the used mask. A mask should not be worn for more than 2 h; however, the frequency of mask replacement can vary, depending on the number of patients encountered and the working environment.

Self-perception of periodontal health and pain experience during periodontal examination in 14- to 15-year-old Danish adolescents

Objective To evaluate different aspects of periodontal examination among Danish adolescents. Materials and methods In all, 521 Danish adolescents underwent a periodontal examination and answered a questionnaire concerning their self-perception of periodontal health (PH). Furthermore, 107 participants reported their pain experience during periodontal examination using a visual analog scale. The self-perception of PH and the pain experience were correlated with plaque score (PS), bleeding on probing (BOP), probing pocket depth (PPD), and interdental clinical attachment loss (CAL). Results Good PH was reported by 424 (81%) of the participants. However, the association between PH and PS, BOP, PPD, and CAL was small (sensitivity: 7.7, 7.8, 12.0, and 0.0%, respectively). Only 57 (11%) of the participants reported bleeding gums (BG) during tooth brushing, but the correlation with BOP showed a sensitivity of 11.7%. The specificity of both self-perception of PH and BG was high. Sixty-seven (66.6%) of the participants experienced ‘mild pain’ during periodontal examination. There were no differences in periodontal outcomes between the pain groups (p > .05). Conclusions The adolescents showed a poor ability to identify themselves as having poor PH and BG, and 67 (66.6%) of the adolescents experienced mild pain during periodontal examination. The findings emphasize the need for dental staff to monitor the PH of Danish adolescents and advise them as necessary.

Digital revolution

The Covid 19 pandemic has had a huge impact on human society as a whole. The field of dentistry is not an exception to this. Adaptation to the new situations in the pandemic, due to the vulnerability of dental staff and students, is highly necessary. To do this newer protocols have been generated that are to be used along with the strict adherence of older safety methods. With the advancements of technology, Teledentistry, online learning and other digital alternatives are being introduced to enhance, preserve and continue the various fields of dental practice and education. With the onset of the pandemic, the amount of research being done in various fields of digital dentistry has increased from 2019 to 2020 compared to that of previous years. This review provides an insight about the digitalization of dentistry, the most common technologies in use, a few technologies that have a promising future and the tremendous rise in the research of digital dentistry.

Health risk assessment of inhalation exposure to dry fogging of hydrogen peroxide in a dental clinic during the COVID-19 pandemic.

After the outbreak of COVID-19, many dental clinics use dry fogging of hydrogen peroxide (H2O2) to disinfect the air and surfaces. Inhalation of highly concentrated solutions of H2O2 may cause severe respiratory problems. This study aimed to estimate the health risk assessments of inhalation exposure to dry fogging of H2O2 in a dental clinic. This cross-sectional, descriptive-analytical study was performed to determine the inhalation exposure and health risk of 9 dental clinic staff with H2O2 in six rooms. Occupational exposure to H2O2 was assessed using the OSHA VI-6 method and a personal pump with the flow rate of 500 mL/min connected to the midget fritted-glass impinger containing 15 mL of TiOSO4 collecting solution. The health effects of H2O2 exposure were assessed using a respiratory symptoms questionnaire. The health risk assessment of inhaled exposure to H2O2 was also performed using the method provided by the Singapore occupational health department. The mean respiratory exposure of clinic staff to H2O2 was ranged from 1.3 to 2.83 ppm for six rooms which was above the limits recommended by international organizations. Dyspnea (44.4%), cough (33.3%), and nasal burning (22.2%) were the most prevalent health problems. The results also showed a medium risk for endodontics and surgery, and lower risk for periodontics, restorative care, orthodontics, and prosthetics. The results of this study indicate that when using an automated hydrogen peroxide–vapor fogger, calculating the spraying time based on room volume and using the rooms after 30 min of fogging is very important and can greatly reduce the risk ranking.
