This was the first longitudinal study to analyze dental clinic wastewater to estimate asymptomatic SARS-CoV-2 infection trends in children. We monitored wastewater over a 14-month period, spanning three major COVID-19 waves driven by the Alpha, Delta, and Omicron variants. Each Saturday, wastewater was sampled at the Pediatric Dental Clinic of the only dental hospital in Japan\'s Saitama Prefecture. The relationship between the weekly number of cases in Saitama Prefecture among residents aged < 10 years (exposure) and wastewater SARS-CoV-2 RNA detection (outcome) was examined. The number of cases was significantly associated with wastewater SARS-CoV-2 RNA positivity (risk ratio, 5.36; 95% confidence interval, 1.72-16.67; Fisher\'s exact test, p = 0.0005). A sample from Week 8 of 2022 harbored the Omicron variant. Compared to sporadic individual testing, this approach allows continuous population-level surveillance, which is less affected by healthcare seeking and test availability. Since wastewater from pediatric dental clinics originates from the oral cavities of asymptomatic children, such testing can provide important information regarding asymptomatic COVID-19 in children, complementing clinical pediatric data.

BACKGROUND: This study aimed to determine the nature, frequency, and characteristics of medical emergencies occurring at the King Abdulaziz University Dental Hospital.
METHODS: The incident reports of medical emergencies recorded at the King Abdulaziz University Dental Hospital from January 2008 to December 2022 were retrospectively reviewed. The annual/overall incidence of medical emergency events was calculated per 100,000 patients. The following characteristics of the patients/events were evaluated: age, gender, operator, procedure, location, timing of treatment, administration of local anesthesia, past medical history, symptoms, diagnosis, outcome, and disposition. Multivariable logistic regression models were used to investigate the associations of these characteristics with two outcomes: syncope and transfer to the emergency room (ER).
RESULTS: The incidence of emergency events was 17.4 per 100,000 patients. Syncope and hypoglycemia were the most common emergencies. Most incidents recovered, with only 13% requiring transfer to the ER. Undergoing no procedure and American Society of Anesthesiologists (ASA) class 2,3 were associated with syncope. Undergoing a general dental procedure, ASA class 2,3, and a diagnosis other than hypoglycemia and syncope were associated with transfer to the ER.
CONCLUSIONS: The incidence of medical emergencies was low. Dental practitioners need to remain aware of the contributing factors, such as past medical history and anxiety, but medical emergencies can occur in healthy individuals as well. Preparation of the dental office, training of the personnel, and proper recording of the events are essential components of a well-established medical emergency protocol in dental institutions.

UNASSIGNED: Oral health literacy (OHL) is the ability of individuals to obtain, process, and understand oral health information and services, allowing them to make appropriate oral health decisions. The association between OHL and tooth loss and replacement have not been well understood.
UNASSIGNED: We aimed to determine the association between OHL and tooth loss and replacement in a Colombia population.
UNASSIGNED: A cross-sectional study of 384 older adults age 65 to 89 years from Pasto, Colombia was carried out. The number of lost and replaced teeth was assessed intraorally; sociodemographic and prosthetic characteristics were collected, and the Health Literacy in Dentistry questionnaire was used to evaluate OHL. Generalized linear models were estimated to assess associations between independent variables (including OHL) and the number of lost and replaced teeth.
UNASSIGNED: There were 224 (58.3%) men and 160 (41.7%) women. The mean (standard deviation [SD]) number of lost and replaced teeth was 27.78 (4.03) and 12.53 (9.89), respectively. One hundred fifty five (40.4%) individuals had full removable dental protheses, 122 (31.8%) partial removable dental protheses, 68 (17.7%) fixed prosthetics, and 36 (9.4%) dental implants. OHL was 33.29 (6.59) and significantly positively associated with the number of replaced teeth (β = 0.65, 95% confidence interval [CI]: 0.52-0.78, p < .001), but not with lost teeth.
UNASSIGNED: OHL may foster individuals\' capabilities to replace lost teeth, although we did not find it associated with reduced tooth loss, likely as tooth loss was highly common in this older population. [HLRP: Health Literacy Research and Practice. 2024;8(1):e21-e28.].
CONCLUSIONS: The association between OHL and tooth loss and replacement has not been well understood. A study of 384 older adults was designed to evaluate the number of lost and replaced teeth and the association with OHL. We found that OHL may foster tooth replacement but was not associated with tooth loss itself.

BACKGROUND: Ocular issues such as impaired vision, ophthalmia, orbital cellulitis, and blindness are not common with dental infections. However, there is absence of set guidelines in prevention and management of ocular issues arising from dental infections. Hence the knowledge and vantage point of the dentists with respect to ocular complications arising from dental infections was evaluated.
OBJECTIVE: This study reviews the knowledge of dentists with association of eye infection due to dental contamination.
METHODS: A cross sectional survey using standardized questionnaires were sent suing social media platform among the academicians and practicing dental clinicians. All the questionnaires were content validated by three ophthalmologists. Descriptive statistics was scrutinized and tabulated by employing the Statistical Package for Social Sciences (SPSS), version 17 (SPSS Inc., Chicago IL). Chi square tests was used.
RESULTS: About 69.1%(65) and 30.9%( 29) of BDS and MDS grduates have experienced ocular complications because of dental contamination. This distribution showed no statistical significance (p = 0.25). 73.8% (183) and 28.2%( 65) had compliance with the eye protection, 77.7% (160) of BDS graduates and 22.3% (46) of MDS graduates preferred safety eye wear. This distribution showed statistical significance (p = 0.00). About 76.2% (279) of BDS graduates and 23.8%( 67) of MDS graduates faced ocular infections because of different types of splashes which included water, blood and saliva. (p = 0.23) CONCLUSION: This study puts an emphasis on the knowledge assessment among the dental practitioners on the importance of preventive barriers, and how special protective gear is required for doing cases undergoing dental treatment.

Frequency of emergency department (ED) use for nontraumatic dental conditions (NTDC) is a well-researched community health concern. However, research predominately relies on ambulatory ED discharge records. This explanatory sequential mixed methods study reviewed NTDC ED use in hot-spot counties and assessed perceptions around preventable and appropriate use among EDs and dental clinics.
Tooth pain data (2015-2021) were drawn from State Medicaid, and the Early Notification of Community-Based Epidemics (ESSENCE). NTDC data were compiled using International Classification of Disease, Ninth and Tenth Revisions. Employing extreme case sampling, providers in counties with the highest per-capita NTDC ED use were interviewed.
North Dakota experienced a decline in NTDC ED visits between 2017 and 2020, though the rate is now increasing. The greatest proportion of NTDC ED visits were among persons ages 20 to 34 and 35 to 44. ED and dental care staff have misconceptions around each other\'s roles in reducing NTDC ED visits, but unanimously suggest community-level prevention as a solution.
NTDC ED use was perceived as \"appropriate\" care. However, there is consensus that improved access to, and utilization of, affordable and quality preventative dental care would reduce NTDC ED visits and improve overall community health, especially among populations experiencing greater inequities.

OBJECTIVE: Cigarette smoking negatively affects oral health. Nicotine replacement therapies (NRT; e.g. nicotine patch or lozenge) and brief interventions (e.g. Ask-Advise-Refer; AAR) can improve cessation outcomes but are underutilized. NRT sampling (NRTS) increases NRT utilization by providing patients with samples of NRT as part of routine healthcare. Ask-Advise-Refer is a brief intervention where practitioners: ask patients about tobacco use, advise those using tobacco to quit and refer to the state quit line. The objective of this qualitative study was to explore dental care practitioners\' and patients\' attitudes and experiences regarding tobacco cessation treatment and perceptions of two brief intervention models, assessed separately: NRTS and AAR.
METHODS: Twenty-four dental care practitioners and nine patients, recruited through the National Dental Practice-Based Research Network, participated in semi-structured telephone interviews. Interviews assessed experiences with tobacco use intervention and attitudes towards NRTS and AAR. Thematic analysis identified emergent themes related to feasibility and acceptability of NRTS and AAR.
RESULTS: Practitioners varied on how they address tobacco use, from systematically to idiosyncratically. Some practitioners recommend NRT; few had prescribed it. Practitioners had favourable attitudes towards AAR and NRTS, with most believing that both interventions would be acceptable and feasible to implement. Concerns regarding AAR were time and patient resistance to discussing tobacco use. Concerns regarding NRTS were patient resistance to using NRT, side effects or medication interactions, and capacity to provide follow-up. Patients reported that oral health practitioners generally ask about tobacco use but do not provide interventions. Patients were open to discussing their tobacco use with practitioners and had favourable attitudes about NRTS.
CONCLUSIONS: This formative work suggests that NRTS and AAR may be feasible to implement in dental care settings. Future studies are needed to assess the effectiveness and implementation potential of NRTS in dental care settings.

Positive psychological well-being has a favorable impact on survival rates in both healthy and unhealthy populations. Oral health is also associated with psychological well-being, is multidimensional in nature, and includes physical, psychological, emotional, and social domains that are integral to overall health and well-being. This study aimed to identify the associations between individual and environmental characteristics, oral condition and nutritional status in relation to subjective well-being among older adults using the Wilson and Cleary conceptual model. The participants were older adults (age ≥ 60 years) attending a university hospital. Subjective well-being was assessed using the World Health Organization-5 Well-Being Index, oral condition was assessed based on the number of bacteria in the tongue coating, oral wettability, tongue pressure, occlusal force, oral diadochokinesis, and masticatory ability, and subjective swallowing function was assessed using the Eating Assessment Tool, number of remaining teeth, and number of functional teeth. In addition, factors related to well-being, including social networks, life-space mobility, nutritional status, smoking history, drinking history, and medical history were assessed. In the analysis, structural equation modeling was used to investigate the association between oral condition and subjective well-being. Confirmatory factor analysis revealed oral condition as a latent variable, including tongue pressure, oral diadochokinesis /pa/, /ta/, /ka/, occlusal force, masticatory ability, subjective swallowing function, and number of functional teeth. Structural Equation Modeling revealed that oral condition was positively correlated with nutritional status, and nutritional status was positively correlated with the World Health Organization-5 Well-Being Index. These findings suggest that oral condition may influence subjective well-being via nutritional status or social environmental factors.

A Legionella pneumophila bacterium is ubiquitous in water distribution systems, including dental unit waterlines (DUWLs). Legionellosis is atypical pneumonia, including Legionnaires\' disease (LD) and the less acute form of Pontiac fever. Legionellosis occurs as a result of inhalation/aspiration of aerosolized Legionella-contaminated water by susceptible patients, health workers, and dentists. In this study, we undertook to determine the prevalence of Legionella in water and biofilm samples from Tap and DUWLs collected from five sites of dental clinics and faculties across the West Bank. Water samples were tested for physical and chemical parameters. The study samples included 185 samples, 89 (48%) water samples, and 96 (52%) biofilm swabs, which were analyzed by cultivation-dependent analysis (CDA) and by the cultivation-independent technique (CIA). Also, partial sequencing of the 16S rRNA gene for fifteen L. pneumophila isolates was performed for quality assurance and identification. L. pneumophila was isolated from 28 (15%) of 185 samples using CDA and was detected in 142 (77%) of 185 samples using CIA. The abundance of culturable L. pneumophila was low in DUWL of the sampling sites (range: 27-115 CFU/Liter). PCR was 5× more sensitive than the culture technique. L. pneumophila Sg 1 was detected in (75%) of the isolates, while (25%) isolates were L. pneumophila Sg 2-14. All fifteen sequenced Legionella isolates were identified as L. pneumophila ≥ 94.5%. The analysis of phylogenetic tree showed that L. pneumophila branch clearly identified and distinguished from other branches. These results show that DUWLs of the examined dental clinics and faculties are contaminated with L. pneumophila. This finding reveals a serious potential health risk for infection of immunocompromised patients and dentists\' post-exposure.

Given the lingering threat of COVID infection, questions are being raised if coronavirus disease 2019 (COVID-19) vaccine needs annual or regular boosters to maintain high levels of immunity against both the original virus and variants. This study was designed to evaluate the knowledge, acceptance, motivators and barriers of the booster dose of COVID-19 vaccine among the dental patients of District Lucknow, India. A total of 297 respondents were selected by a convenience sampling method in this cross-sectional study from various dental clinics. An anonymous, self-administered, closed-ended questionnaire was used. Overall 37.7% respondents reported to have taken all 3 doses and 57.9% had taken single/double doses. Correct information about booster doses shows a significant association with the number of doses taken. The majority had information about the availability of the Pfizer booster vaccine (69.0%). About 58% of participants had information about the technology used in booster doses. The hesitancy for booster doses and the development of natural immunity by infection show significant associations with the number of doses taken. Only 18.2% patients had hesitation about the booster dose and most of them 78.8% recommended others to take the booster vaccine as soon as possible. The majority assumed that previous COVID-19 vaccines can help them get immune (21.5%) followed by not much research has been done on the booster vaccines (15.5%) and their chronic diseases warn them against the booster dose administration (12.5%). Nearly 18.2% of respondents had hesitation about booster dose and less than one third of the respondents trusted a government source for information about booster dose of COVID vaccine. Nearly 36 % did not know that the booster dose of COVID vaccine is available at health centers. Dental health professionals and policymakers should implement and support strategies to ensure people are vaccinated for COVID-19 booster doses.

BACKGROUND: Practical hands-on training is necessary for clinical competence in managing medical emergencies in the dental setting. Therefore, the King Abdulaziz University Faculty of Dentistry developed a role-play simulation-based clinical module for training clinical years (Years 4, 5, and 6) dental students in medical emergency management between 2016 and 2020. This study aimed to assess the knowledge and skills of years 4, 5, and 6 dental students before and after the completion of the role-play simulation-based medical emergency training module.
METHODS: A mandatory four-hour annual training module was designed consisting of a 45-minute lecture on the medical emergency basic action plan and overview, four hands-on stations, and six role-play simulation-based medical emergency stations. A 16-item multiple choice test was used to assess the knowledge of the students before and after the training module every academic year. An objective structured clinical exam (OSCE) on a medical emergency scenario was administered to the students graduating each year. The difference between the pre- and post-module test scores and the one-time OSCE pass/fail rate were analyzed statistically using appropriate tests.
RESULTS: A total of 846 students participated in the study between 2017 and 2020: 275 once, 483 twice, 87 thrice, and one participated four times; in total, 1,506 assessments were conducted. Overall, the pre-test and post-test mean scores were 9.4 ± 3.0 and 13.5 ± 1.6, respectively. All students showed significant improvements in the post-test scores compared to the pre-test scores. Year 4 students showed the highest improvement, followed by Year 5 and Year 6. There was a statistically significant association between the pass/fail rate of the OSCE station and the number of times the module was taken.
CONCLUSIONS: The significant improvement in the scores of clinical year students in this study supports an annual mandate for all dental students to undergo simulation-based competency training in their clinical years. Teaching institutions are recommended to utilize simulation and hands-on instruction to teach medical emergency management.
