Oral health promotion activities in the workplace: a scoping review

There is limited literature and no reviews on oral health promotion activities in the workplace to guide planning and practice. This review summarizes evidence about oral health promotion activities in the workplace (nature and extent), its impact and the factors that facilitate or act as barriers to implementation. Using the PRISMA-ScR guidelines, scientific articles written in English and published in peer-reviewed journals up to April 2021, from six databases (Medline, PubMed, CINAHL, Scopus, EMBASE and Emcare) were screened and selected. The full texts of 95 articles were then considered; 21 articles met the inclusion criteria of using oral health status or oral health predisposing factors as primary outcome after an intervention in the workplace. Almost all included articles took a quantitative approach (n = 18), two used a qualitative design and another used a mixed-method approach. The most common activities were personalized or group oral health education interventions and oral health screenings conducted by a dental professional. Two studies reported the cost-benefit of workplace oral health promotion (WOHP). The literature indicated that WOHP interventions can be successful in achieving improvements in oral health, measured using a range of clinical (plaque accumulation, gingival inflammation, periodontal inflammation) and self-rated oral health indicators. Based on the limited literature available, WOHP may have benefits for employee oral health and employers, and the support of managers and organizations potentially improves the success of programmes. The workplace would appear to be an ideal setting to promote oral health. However, there is limited information to guide oral health promotion planning and implementation, and policy.
