Skin reactions among Bulgarian dental students: A self-report questionnaire survey

Prevalence of Occupational Contact Dermatitis Among Dental Personnel Using the Nordic Occupational Skin Questionnaire-2002: A Prospective Cross-Sectional Study

BACKGROUND

Occupational skin disease (OSD), such as contact dermatitis, is widespread among dental professionals; however, reports regarding its prevalence have inconsistent findings and methodology. Therefore, we conducted a cross-sectional survey using a self-reported questionnaire to estimate the prevalence of work-related and occupational exposure-induced skin diseases.

METHODOLOGY

A self-administered questionnaire, based on the validated Nordic Occupational Skin Questionnaire-2002, was distributed to 15 dental clinics in Israel in the first half of 2022. The questionnaire included questions about the occupation, exposure, and history of atopic disease, dry skin, and hand/arm and wrist eczema, as well as participant demographics.

RESULTS

Overall, 312 dental professionals completed the questionnaires. Response rate was 80%. The lifetime prevalence of self-reported skin symptoms was 19.23%. Significant risk factors included exposure to metal objects, odds ratio (OR): 2.43, 95% confidence interval (CI): [1.02, 5.78]; p < .05, dry skin (OR: 3.54, 95% CI: [1.93, 6.5]; p < .001), itching when sweating (OR: 2.89, 95% CI: [1.39, 6]; p < .05), contact urticaria (OR: 10.67, 95% CI: [4.46, 25.49]; p < .001), hay fever (OR: 2.25, 95% CI: [1.14, 4.42]; p < .05), allergic symptoms (OR; 2.33, 95% CI: [1.18, 4.58]; p < .05), and asthma (OR: 4.8, 95% CI: [2.17, 10.36]; p < .001).

CONCLUSIONS

This is the first study to use the NOSQ-2002 among dental professionals. Our study provides a better understanding of the prevalence and consequences of OSDs among dental personnel by utilizing the validated tool NOSQ-2002.

Patch test results in dental staff with dermatitis

BACKGROUND

Dental workers are exposed to allergenic materials in the workplace.

OBJECTIVES

To summarize patch test results in dental staff with work-related dermatitis.

MATERIALS AND METHODS

Cross-sectional study of dental staff with dermatitis was conducted. Symptoms, clinical findings and results from patch tests with 40 dental allergens were summarized.

RESULTS

Of 329 participants, 155 (47.1%) had at least one positive patch reaction. The highest frequency of positive reactions was observed for metals (38.6%), acrylics (7.3%) and additives in acrylic resins (3.6%). One hundred and eighty-five (56.2%) participants were currently symptomatic; in this group, 79 (42.7%) had current dermatitis. Thirty-eight patients had at least one positive patch test considered occupationally related to their current dermatitis.

CONCLUSION

Almost half of the dental staff with dermatitis had at least one positive patch test and approximately 12% had current occupational relevance of the allergens. Our results underscore the importance of patch testing in the evaluation of dental staff with dermatitis.

Mask-related adverse skin reactions in orientals during COVID-19: Prevalence, social-psychological impacts and risk factors for acne exacerbation

BACKGROUND

COVID-19 pandemic has caused mask-related skin problems on health-care professions, yet very few studies have investigated the prevalence in oriental general population.

OBJECTIVE

To investigate the prevalence of mask-related adverse skin reactions in Orientals, to explore psychological influence, to identify risk factors for mask-related acne exacerbation.

METHODS

We performed a survey through social media. Participant demographics, skin condition before and after COVID-19, and the influence of adverse skin on social-psychological conditions were collected. We compared characteristics between individuals with or without acne exacerbation, and we performed a logistic regression to identify risk factors.

RESULTS

Six hundred and six participants (62.3%) responded the survey and 23.3% complained their facial acnes become exacerbated since COVID-19. The social-psychological impact of acnes is more prevalent in women. Risk factors for mask-related acne exacerbation were occupation as health-care workers (OR = 1.861, p = 0.027), prolonged wearing of N95 masks (OR = 3.167, p = 0.001), and touching of acnes (OR = 2.65, p = 0.002). Sex, pre-existed acnes, and prolonged wearing time per day are also associated with acne exacerbation.

CONCLUSIONS

Mask-related adverse skin reactions are common in Orientals, and could lead to negative social-psychological effects.

In Vitro Analysis of the Mechanical Properties of Hypoallergenic Denture Base Resins

The development of hypoallergenic denture resins is key to the treatment of patients with allergies to polymethyl methacrylate (PMMA). In this study, the in vitro mechanical properties of hypoallergenic and PMMA denture base resins were compared. Ninety-six test specimens of hypoallergenic denture base resins (Polyan Plus^®, Sinomer, TMS Acetal Dental, Erkocryl) and 72 test specimens of PMMA-based denture base resins (Paladon 65, PalaXpress, SR-Ivocap) were fabricated. The flexural strength, elastic modulus, compressive strength, macro- and microhardness, average roughness, water absorption, and water solubility of the resins were measured. None of the hypoallergenic denture resins matched all the mechanical properties of the PMMA resins. Polyan Plus^® and TMS Acetal Dental were closest to matching the mechanical properties of the PMMA resins, and TMS Acetal Dental had some superior properties. Consequently, Polyan Plus^® and TMS Acetal Dental hypoallergenic resins are recommended for further investigation as potential alternatives to PMMA resins for the fabrication of removable dentures.

Hand hygiene and hand eczema: a systematic review and meta-analysis

Hand eczema is a common inflammatory condition of the skin that has been linked to hand hygiene. This systematic review and meta-analysis aims to determine the risks of hand eczema associated with hand hygiene, including frequency of handwashing, wet-work and use of alcohol hand rub. A comprehensive search of MEDLINE, EMBASE and Cochrane Library was performed for cohort, case-control or cross-sectional studies that analysed the association between hand hygiene and risk of hand eczema. Results of individual studies were presented in respective forest plots and pooled summary relative risks were estimated using a random-effects model. Forty-five studies were included in analysis. Handwashing at least 8-10 times daily significantly increased risk of hand eczema (relative risk [RR] 1.51; 95% confidence interval [CI]: 1.35-1.68; P < .001). The risk was related to handwashing frequency, with higher pooled RR of 1.66 (95%CI: 1.51-1.83; P < .001) with increased handwashing at least 15-20 times daily. However, use of alcohol-based hand sanitizer was not significantly associated with risk of hand eczema. Given the widespread implementation of hand hygiene practices during the COVID-19 pandemic, there is a pertinent need to understand skin care habits specific to the hands to avoid a greater incidence of hand eczema.

Work-related skin symptoms among Bulgarian dentists

BACKGROUND

Dentists are at high risk of developing skin symptoms due to occupational contact with irritants and/or allergens.

OBJECTIVES

To assess the point prevalence of work-related skin symptoms and associated factors in Bulgarian dentists.

METHODS

A cross-sectional study was performed using a self-report questionnaire.

RESULTS

A total of 4675 dentists filled the questionnaire (response 48.1%). The point prevalence of self-reported skin symptoms was 31.6%. According to logistic regression analysis, factors significantly associated with work-related skin symptoms included a personal history of atopic dermatitis (odds ratio [OR] 2.72, 95% confidence interval [CI]: 2.24-3.31), allergic rhinoconjunctivitis and/or asthma (OR 1.85, 95%CI: 1.56-2.19), work experience >30 years (OR 2.21, 95%CI: 1.78-2.74), personal history of contact allergy (OR 1.79, 95%CI: 1.48-2.17), female sex (OR 1.87, 95%CI: 1.59-2.19), hand washing >8 times a day (OR 1.32, 95%CI: 1.03-1.69), daily contact ≥4 hours with protective gloves (OR 2.09, 95%CI: 1.64-2.67), and use >10 pairs of gloves per day (OR 1.51, 95%CI: 1.11-2.04).

CONCLUSION

Bulgarian dentists have a high prevalence of work-related skin symptoms. History of atopic dermatitis, prolonged work experience, and protective gloves use were the strongest risk factors.
