INTRODUCTION: Implicit bias is a form of unconscious bias that can affect judgment, decisions, and behaviors. OBJECTIVES: This scoping review examined what scientific literature exists about implicit bias demonstrated by dental/dental hygiene students and providers and, when possible, how these implicit biases are associated with patients' oral health outcomes. METHODS: This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR). This review included English-language PubMed peer-reviewed studies meeting inclusion criteria, published through October 2023, measuring the implicit bias of dental/dental hygiene students or professionals and how such bias can affect patient oral health outcomes. RESULTS: A total of 363 records were found. After removing duplicates ( CONCLUSION: Despite small sample sizes and a lack of racial/ethnic diversity that limit their generalizability, the included studies provide evidence for implicit racial bias held by some dental/dental hygiene students and professionals that may affect the oral health outcomes of patients. Training to increase awareness of and reduce implicit bias among those providing oral health care is an important first step to providing a more equitable health care system for all patients.Knowledge Transfer Statement:Despite small sample sizes and a lack of racial/ethnic diversity that limit their generalizability, the included studies provide evidence for implicit racial bias held by some dental/dental hygiene students and professionals that may affect the oral health outcomes of patients.
