Oral Health and Hygiene Status of Global Transgender Population: A Living Systematic Review and Meta-Analysis

Due to several interpersonal, social, and organizational challenges, dental health has been occasionally compromised in the transgender population. There is a lack of awareness among transgender persons to access affordable trans-competent oral health care. More information is required to identify and assess the oral health condition of this population in order to encourage better access to oral healthcare and effectively influence public health policy and practice. This systematic review aims to provide evidence about the status of oral health and hygiene of the transgender population across the globe. A systematic literature search using keywords and MESH search terms was conducted using PubMed, Medline, Google Scholar, and EBSCO online databases. The references of included journal articles were manually searched and appropriate studies were included, which were then critically appraised using the Joanna Briggs Institute (JBI) tool and the Newcastle–Ottawa protocol for the risk of bias assessment of prevalence studies, with each study assessed by two independent reviewers. Based on the search procedures, a total of 2026 articles were initially screened and, after evaluation, 20 were included in the systematic review. Transgender persons often face stigma and discrimination in dental healthcare settings, which affects their oral health status. A greater prevalence of substance abuse stemming from anxiety, lack of adequate education, and poor socioeconomic status leads to an increased prevalence of oral health diseases in this marginalized population. There is a need for policies and reforms to appraise their oral health and hygiene status and improve access to oral health services in this population.
