John Vivian Bingay OBE (1899-1973) and the New Cross School for Dental Auxiliaries.

It is easy to forget some of the people who helped to develop the dental care services. One person who should be remembered is Jack Bingay. He was a towering figure in the public dental services from just before to well after World War II. Jack was the first Director of the School for Dental Auxiliaries.

Secular trends in dental services provided by dental therapists and dentists in Southwest Alaska.

BACKGROUND: The goal of the study was to identify secular trends in dental service delivery between dental therapists and dentists in the Yukon-Kuskokwim Delta region of Southwest Alaska, the first area of the United States to authorize dental therapy practice. METHODS: Electronic health record transactions from the Yukon-Kuskokwim Health Corporation from 2006 through 2015 (n = 27,459) were analyzed. Five types of dental services were identified using Current Dental Terminology procedure codes: diagnostic, preventive, restorative, endodontic, and oral surgery. Main outcomes were percentages of services provided by dental therapists compared with dentists and population-level preventive oral health care. RESULTS: The overall number of diagnostic, preventive, and restorative services in the Yukon-Kuskokwim Delta increased. For diagnostic services, there was a 3.5% annual decrease observed for dentists and a 4.1% annual increase for dental therapists (P < .001). Similar trends were observed for restorative services. For preventive services, there was no change for dentists (P = .89) and a 4.8% annual increase for dental therapists (P < .001). Dental therapists were more likely than dentists to provide preventive care at the population level. CONCLUSIONS: Dental therapists have made substantial contributions to the delivery of dental services in Alaska Native communities, particularly for population-based preventive care. PRACTICAL IMPLICATIONS: The study's findings indicate that there is a role for dental therapy practice in addressing poor access to oral health care in underserved communities.

The knowledge, attitude and practice level of dental auxiliaries regarding oral health care for pregnant patients in the eastern province of Saudi Arabia.

Background : The purpose of this research was to assess the knowledge, attitude, and practice of dental auxiliaries related to oral health care for pregnant patients in the Eastern Province of Saudi Arabia. Methods: A cross-sectional study using a questionnaire survey was conducted. The knowledge, attitude, and practice were rated using the Likert scale out of 5. Knowledge and practice were categorized using Bloom's cut off point methods (≥80% is good, and <80% is bad) . Concerning attitude, (≥80% is positive, and <80% is negative). The questionnaires were sent to all dental hygienists and assistants (N=358), and responses were collected from 218. Statistical Package for the Social Sciences (SPSS) software was utilixed to conduct statistical analysis. Results: Out of the 358, 218 responded (response rate = 61%).  More than half of the respondents showed relatively good knowledge (57.3%). Most respondents had a positive attitude (89.4%). Regarding practice, approximately two-thirds had a good practice (67.4%). The knowledge score of hygienists was significantly higher than dental assistants, and respondents with experience in treating pregnant patients had significantly higher knowledge scores than others who did not have experience in treating pregnant patients. There is a statistically significant positive correlation between practice scores and education. Conclusions: The findings suggest the need to establish continuous education programs and for dental hygienists and dental assistants to adopt the best practice guidelines on perinatal oral health.

Pro-CAD: una alternativa para profesionalizar al personal auxiliar del odontólogo / Pro-CAD: a professionalizing alternative for the dentist's auxiliary staff

El presente artículo es el resultado de una investigación orientada a la implantación de un modelo educativo, que sustenta una propuesta para la capacitación de recursos humanos de apoyo técnico en el campo de la salud. Para este propósito se denominaron: Asistentes Dentales a quienes son el personal auxiliar que se desempeña con profesionales que ejercen la odontología en forma privada en México, y que no cuentan con escuelas para su formación, considerando sus diferencias individuales e involucrando las áreas cognoscitiva (conocimientos), psicomotriz (habilidades y destrezas) y afectiva (comportamientos). Los recursos humanos compiten fuertemente por encontrar un espacio de desempeño en un mercado altamente exigente, razón por la cual el eje principal de la investigación se fundamentó en el planteamiento del Consejo Normalizador y Certificador de Competencias Laborales (CONOCER). El modelo fue diseñado durante la formación doctoral, enmarcado en la línea de innovación curricular para la calidad total como consecuencia del interés personal por evaluar las competencias del personal auxiliar que se desempeña apoyando al gremio de la odontología; la población está organizada en un colegio local de profesionales filial a la Asociación Dental Mexicana. Se utilizó el método mixto, y la herramienta para recolección de datos fue la encuesta, misma que aportó información relevante para construir una propuesta denominada modelo Pro-CAD (Programa de Capacitación Asistente Dental), que se incluye brevemente al final de este artículo (AU)

This article is the result of research aimed at the implementation of an educational model, which supports a proposal for the training of human resources of technical support in the field of health. For this purpose they were called: Dental Assistants, who are the auxiliary staff who work with professionals who practice dentistry privately in México, and who do not have schools for their training considering their individual differences and involving the cognitive areas (knowledge), psychomotor (skills and skills), affective (behaviors). Human resources compete strongly to find a performance space in a highly demanding market, which is why the main focus of the research was based on the approach of the Standardizing Council and Labour Skills Certificater (CONOCER). The model was designed during my doctoral training framed in the line of curriculum innovation for total quality as a result of the personal interest in evaluating the work skills of the auxiliary staff who perform supporting the dental guild, the population is organized in a local college of professionals affiliated with the Mexican Dental Association. The mixed method was used, and the data collection tool was the survey, which provided relevant information to build a proposal called the Pro-CAD (Dental Assistant Training Program) model that is briefly included at the end of this article (AU)

An analysis of YouTube videos as educational resources for dental practitioners to prevent the spread of COVID-19.

BACKGROUND: Coronavirus disease (COVID-19) was first reported on 31 December 2019 and has rapidly been spreading day by day. Dental patients and professionals have a high risk of the coronavirus infection and also have a huge responsibility to prevent its spread during emergency dental treatment over the period of the COVID-19 outbreak. AIM: Informing patients and dental practitioners about the novel coronavirus in an accurate and effective way is very important. Therefore, this study aimed to evaluate the quality of dentistry-related medical information about COVID-19 on YouTube as educational resources for dental practitioners. METHODS: YouTube was queried for the search phrases 'COVID-19 and dental practice', 'SARS-Cov-2 and dental practice' and '2019-COV-2 and dental practice'. The first 100 videos for each term were viewed and analysed by 3 independent investigators. The scope was limited to videos in English. RESULTS: The search phrases yielded 1102 videos, among which 802 videos were excluded and 300 videos screened. Fifty-five videos were included in the final analysis. Of the 55 videos, only 2 videos (3.6%) were found to be of good quality, while 24 videos (43.6%) were found to be of poor quality. CONCLUSION: YouTube is a popular video broadcast site and can provide both relevant educational information and the spreading of misinformation. Health professionals should play a more active role with regard to educative information given on social media, especially YouTube, during global disease outbreaks.

Can preprocedural mouthrinses reduce SARS-CoV-2 load in dental aerosols?

Dental professionals work closely with patients and present an increased risk of person-to-person transmission of SARS-CoV-2. Moreover, the use of ultrasonic scalers, air-water syringes, and slow and high-speed handpieces, which are common in the dental office, generate spatter and aerosol. The use of preprocedural mouthrinses has been proposed to reduce the viral load in saliva and oropharyngeal tissues, thus decreasing viral load in dental aerosol. Although some mouthrinses demonstrates an antiviral effect, there is limited evidence about the clinical efficacy of any mouthrinse in the reduction of SARS-CoV-2 in the dental aerosol. We hypothesized that mouthrinses may reduce SARS-CoV-2 viral load in the oropharynx and its fluids reducing viral load in dental aerosol. The potential use of mouthrinses is discussed, along with proposal of in vitro and clinical studies, in order to evaluate this hypothesis. If this hypothesis holds true, dental professionals and patients may benefit from the routine use of preprocedural mouthrinses.

In Dentistry, Dental Surgery Assistants (DSA) are gaining more space by composing the oral health teams, favoring ergonomic and biosafety aspects, increasing productivity in the dental surgery and providing greater efficiency. In Brazil, in 2008, the Law 11,889 regulated the professional activity of this category. The regulation of the profession implies the adoption of procedures that allow to describe the professional profile and characterize the activities performed by these professionals. A questionnaire is an instrument that can be used for this purpose. The aim of this study was to measure psychometric properties of a questionnaire designed to identify the work characteristics of Dental Health Assistant (DHA). The project was approved by the Research Ethics Committee of the Federal University of Minas Gerais (CAAE n. 17378718.5.0000.5149 of 10/02/2019). The questionnaire was designed according to the Law 11,889 that regulated the professional activity of this profession, in Brazil. It contains 21 questions, seven referring to personal identification and 14 about professional attributions and was sent to 75 DHA through the WhatsApp app. The questionnaire was applied twice to the same participants, with an interval of one week. In the analysis of psychometric properties, internal consistency was verified through the total Cronbach's Alpha coefficient and temporal stability through Cohen's Kappa. The SPSS software version 25.0 was used for analysis. The internal consistency of the 14 questions related to the professional attributions resulted in a Cronbach's Alpha coefficient equal to 0.949 and a Cohen's Kappa coefficient greater than 0.6 in all questions. There was no major change in Cronbach's Alpha coefficient when any questions were removed. The psychometric properties found were considered satisfactory, revealing that it is an instrument with adequate reliability and temporal stability.

Knowledge of dentists, dental auxiliaries, and students regarding the COVID-19 pandemic in Saudi Arabia: a cross-sectional survey.

BACKGROUND: This study aimed to assess the knowledge of dental professionals in Saudi Arabia regarding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and coronavirus disease 2019 (COVID-19). METHODS: A questionnaire was developed to assess various dental professionals from both governmental and private sectors through online and social media outlets. RESULTS: A total of 1,033 questionnaires were collected (273 dental students, 193 dental auxiliary personnel, 544 dentists). In all, 63.4% of the respondents worked in hospitals. Of all the respondents, 44.9%, 33.4%, and 21.7% worked in governmental clinics, academia, and the private sector, respectively. Overall knowledge of the incubation period and route of transmission of SARS-CoV-2 was consistent across all dental professions. Knowledge of hand-soap cleaning time was significantly different among dental professionals (p < 0.001). Dental professionals displayed significant disagreement on the survival of SARS-CoV-2 outside the host (p < 0.001). Furthermore, 75.1% of the respondents were reluctant to treat a suspected COVID-19 patient, and 92% of the participants believed that the mode of transmission was droplet inhalation. Fever, coughing, and shortness of breath were identified as the most common symptoms of COVID-19. Most standard methods of prevention in the dental office were selected by at least 50% of the participants. CONCLUSIONS: Dental professionals seem to be consistent regarding their knowledge of the incubation period of SARS-CoV-2. However, knowledge of viral survivability and recommended hand-soap washing time was significantly variable among the professionals. A high degree of apprehension toward suspected COVID-19 patients existed among all dental professionals. Pandemic-awareness campaigns are essential among healthcare providers.

Ergonomic risk exposure and work ability among young dental professionals in China: A cross-sectional study.

BACKGROUND: Exposure to high ergonomic risk resulted in an increasing prevalence of musculoskeletal disorders among dental professional. However, little is known about the high exposure risk impact on work ability among dental professionals. OBJECTIVE: We conducted a cross-sectional study to examine the association between ergonomic risk exposure and work ability among young dental professionals in their early careers. METHODS: A total of 230 dental professionals including dentists, dental assistants, and nurses were clustered sampled from three hospitals in Guangzhou, south of China. We used the Quick Ergonomic Check (QEC) to assess participants' ergonomic risk exposure and Work Ability Index (WAI) to evaluate their work ability. Demographics and other factors related with WAI were also included in the data collection. Multiple linear regression was applied to analyze the association between ergonomic exposure scores and WAI. RESULTS: A total of 218 participants (94.8%) had valid data and consent forms. The participants' average WAI was 39.6, of which the poor and moderate WAI composed 31%. High and very high ergonomic risk exposure level was 45.9% for the neck and 21.1% for the wrist/hand. In general, WAI decreased with higher ergonomic exposure level. With adjustment of other potential risk factors, the ergonomic scores for wrist/hand and total scores for the whole body were significantly associated with the decreased WAI. CONCLUSION: High ergonomic risk exposure might risk in reducing work ability among young dental professionals. Intervention measures toward ergonomic risk should be taken to prevent WAI from decreasing in their early careers.

Risk for dental healthcare professionals during the COVID-19 global pandemic: An evidence-based assessment.

OBJECTIVES: Heightened anxiety among dental healthcare professionals (DHPs) during the COVID-19 pandemic stems from uncertainties about the effectiveness of personal protective equipment (PPE) against dental aerosols and risk levels of asymptomatic patients. Our objective was to assess the risks for DHPs providing dental care during the pandemic based on available scientific evidence. METHODS: We reviewed the best available evidence and estimated the annualized risk (p=das(1-1-p0p1(1-e)yn) for a DHP during the COVID-19 pandemic based on the following basic parameters: p0, the prevalence of asymptomatic patients in the local population; p1, the probability that a DHP gets infected by an asymptomatic patient; e, the effectiveness of the PPE; s, the probability of becoming symptomatic after getting infected from asymptomatic patient; da, the probability of dying from the disease in age group a; n, number of patients seen per day; and y, number of days worked per year. RESULTS: With the assumption that DHPs work fulltime and wear a N95 mask, the annualized probability for a DHP to acquire COVID-19 infection in a dental office, become symptomatic, and die from the infection is estimated at 1:13,000 (0.008 %) in a medium sized city in the US at the peak of the pandemic. The risk estimate is highly age-dependent. Risk to DHPs under the age of 70 is negligible when prevalence of asymptomatic cases is low in the local community. CONCLUSIONS: Risk of COVID-19 transmission in dental office is very low based on available evidence on effectiveness of PPE and prevalence of asymptomatic patients. Face shields and pre-procedure oral rinses may further reduce the risks. CLINICAL SIGNIFICANCE: DHPs should follow guidelines on pre-appointment protocols and on PPE use during dental treatments to keep the risk low.

Novel corona virus disease (COVID-19) awareness among the dental interns, dental auxiliaries and dental specialists in Saudi Arabia: A nationwide study.

BACKGROUND: Dental health care workers (DHCW's) are invariably at a higher risk of contracting COVID-19. The objectives were; to investigate the current knowledge on COVID-19 among the DHCW's; and to conduct quasi-experiment among the DHCW's who were unaware of the disseminated COVID-19 information. METHODS: A nationwide cross-sectional study targeting dental interns, auxiliaries, and specialists with a two-staged cluster sampling technique was performed. A 17-item questionnaire was subjected to reliability and validity tests before being administered. The participants for quasi-experiment were separated from the original sample after their initial response. Chi-square test assessed responses to knowledge statements between the participants. Difference in mean knowledge scores between the categories of DHCW's and sources of COVID-19 information was assessed using ANOVA. Data from the quasi experiment (pre vs post knowledge intervention) was subjected to paired t-test. Percentage of DHCWs providing correct or wrong responses to each knowledge statement at baseline and after 7 days were compared using McNemar test. RESULTS: The overall sample consisted of 706 (N) participants, and the DHCW's with no prior knowledge on COVID-19 (N=206) were part of the quasi experiment. Findings from cross-sectional study revealed that knowledge was significantly (p<0.05) related to the qualification level (interns vs auxiliaries vs specialists). However, the difference in the source of information (WHO/CDC vs Journal articles vs MoH) did not demonstrate any effect. Number of participants with correct responses to knowledge questions had significantly (p<0.05) increased after intervention. Also, the overall mean knowledge score (10.74±2.32 vs 12.47±1.68; p<0.001) had increased significantly after the intervention. CONCLUSION: In conclusion, the basic knowledge on COVID-19 among the DHCW's in Saudi Arabia is acceptable. Timely dissemination of information by the Ministry of Health, Saudi Arabia had a positive impact on the COVID-19 knowledge score of the DHCW's.

The role of healthcare professionals in HPV communication with head and neck cancer patients: A narrative synthesis of qualitative studies.

INTRODUCTION: Prevalence rates of human papillomavirus positive (HPV+) head and neck cancers (HNC) have increased over the last decades. Communicating about HPV is an increasingly relevant part of HNC patient care. This systematic review was conducted to explore healthcare professionals' (HCP) views and experiences of discussing HPV with HNC patients. It also examined perceptions among different HCP groups of their professional roles in HPV discussions. METHODS: A narrative synthesis of qualitative research was conducted. Three databases-Embase, PsycINFO and CINAHL+-were searched from January 2007 to August 2018. Relevant data were extracted and synthesised thematically. RESULTS: Five studies were identified: four were qualitative and one used mixed methods. HCPs varied in their experience and views of discussing HPV. HCPs who engaged in these discussions believed they were beneficial for patients. All HCPs described the need to address their HPV knowledge deficits in order to provide clear HPV information. Changes in professional roles which were linked to HPV communication for HCPs involved in HNC patient care were also evident. CONCLUSIONS: Effective HPV discussions are an important part of patient-provider interactions. Evidence-based interventions and professional development activities which support HCPs in their HPV discussions with patients would be valuable.

Dental auxiliary hepatitis B immunization: a cross-sectional study in the São Paulo state public health system, Brazil, 2018. / Imunização contra hepatite B em auxiliares em saúde bucal: estudo transversal no sistema público de saúde do estado de São Paulo, em 2018.

OBJECTIVE: to investigate dental auxiliaries (DA) hepatitis B immunization in Brazilian National Health System (SUS) services in nine cities in São Paulo State, Brazil, in 2018. METHODS: this was a cross-sectional study based on interviews using a questionnaire as well as evaluation of immunity using the anti-HBs test, evaluation of prior testing, test result and interpretation and guidance provided about hepatitis B. RESULTS: of the 70 registered DA, 35 completed the course of vaccinations, 29 had negative anti-HBs test results, 16 had tested previously, and 43 did not correctly understand their result; there was association (p=0.025) between completed course of vaccinations and receipt of guidance. CONCLUSION: most DA received guidance about hepatitis B; however, a considerable portion did not complete the course of vaccinations and had negative anti-HBs test results; few DA had tested previously nor correctly interpreted the result; evidence was found of an alarming scenario in which there are severe shortcomings in DA hepatitis B immunization.

Work-related musculoskeletal symptoms and coping strategies among dental auxiliaries at hospital universiti Sains Malaysia.

BACKGROUND: Dental personnel are vulnerable to work-related musculoskeletal symptoms (WMSS) due to the nature of their profession. AIM: To determine WMSS experienced by dental auxiliaries and their coping strategies toward these symptoms. SETTING AND DESIGN: A cross-sectional study was conducted on 82 dental auxiliaries at a university dental hospital in Malaysia. MATERIALS AND METHODS: Nordic musculoskeletal questionnaire and the Brief COPE questionnaire were used to measure the musculoskeletal symptoms and coping strategies of the respondents, respectively. Data were analyzed using IBM SPSS version 22.0. RESULTS: Dental auxiliaries consisted of dental staff nurses (30.5%), dental surgery assistants (40.2%), dental technologists (18.3%), and healthcare assistants (11.0%). Their mean [standard deviation (SD)] age was 33.4 (7.60) years. Most of the respondents had been troubled with ache, pain, and discomfort at the neck, 54.9% (95% confidence interval 44.0%, 66.0%]. In addition, they were troubled mainly with distress at the low back (34.1%) and the ankle or feet (34.1%) which had prevented the respondents from doing their regular job over the past 12 months. The most common areas that had troubled the respondents over the past 7 days were the neck (36.6%), low back (36.6%), and ankle or feet (36.6%). The coping strategy most commonly practiced by the respondents was religion with a mean (SD) score of 3.70 (2.15), followed by active coping [3.13 (0.68)] and acceptance [3.13 (0.69)]. CONCLUSION: The prevalence of WMSS was high in the dental auxiliaries particularly in the neck region. The most common coping strategy used was religion. Awareness programs on the prevention of WMSS among the dental auxiliaries should be increased.

Coronavirus (SARS-CoV-2) y el entorno odontológico / Coronavirus (SARS-CoV-2) and the dental environment

El coronavirus (SARS-CoV-2) es un virus que afecta las vías respiratorias del huésped infectado, provocando daños no solamente a ese nivel, sino una disfunción multiorgánica que provoca la muerte de la persona infectada. Factores como la edad (adultos mayores), comorbilidades (obesidad, diabetes, hipertensión, etcétera) favorecen que la afectación por este virus sea más letal. Esta pandemia que inició en China y se ha expandido en una gran cantidad de países en todo el mundo ha obligado a los servicios de salud no solamente a atender la pandemia, sino a desarrollar protocolos para la atención de los pacientes y la protección del personal de salud (AU)

The coronavirus (SARS-CoV-2) is a virus that affects the airways of the infected host, causing damage not only at that level, but also multiorgan dysfunction that causes its death. Factors such as age (older adults), comorbidities (obesity, diabetes, hypertension, etc.) favor that the affectation by this virus is more lethal. This pandemic that started in China and has spread in many countries around the world has forced health services not only to attend to the pandemic but also to develop protocols for the care of patients for their protection and the personnel of health (AU)
