reasons, it is imperative that dental professionals understand the different types of metals used in biomaterials, factors that increase corrosion susceptibility of dental restorations, and corrosion’s potential to increase patient hypersensitivity to Implicit bias in healthcare Implicit bias significantly affects how healthcare professionals perceive and make treatment decisions, ultimately resulting in disparities in health outcomes. These biases, often unconscious and unintentional, can shape behavior and produce differences in medical care along various lines, including race, ethnicity, gender identity, sexual orientation, age, and socioeconomic status. Healthcare disparities stemming from implicit bias can manifest in several ways. For example, a healthcare provider might unconsciously give less attention to a patient or make assumptions about their medical needs based on race, gender, or age. The unconscious assumptions can lead to delayed or inadequate care, misdiagnoses, or inappropriate treatments, all of which can adversely impact health outcomes. Addressing
metals. Doing so will help dental professionals make better- informed decisions about which biomaterials are the safest and most effective.
implicit bias in healthcare is crucial for achieving equity in medical treatment. Strategies to combat these biases involve education and awareness programs for healthcare professionals. These programs help individuals recognize and acknowledge their biases, fostering a more empathetic and unbiased approach to patient care. Additionally, implementing policies and procedures prioritizing equitable treatment for all patients can play a pivotal role in reducing healthcare disparities. Ultimately, confronting implicit bias in healthcare is essential to creating a more just and equitable healthcare system where everyone receives fair and equal treatment regardless of their background or characteristics.
THE ROLE OF METALS IN HEALTH
Metals, such as iron, zinc, copper, manganese, chromium, selenium, and boron, occur widely in nature and are essential for human health (Harvard Health Publishing, 2021; National Institutes of Health [NIH], 2016; Marieb and Hoehn, 2018). Only trace amounts of these metallic elements are needed to support a variety of enzymatic, metabolic, and biochemical functions (Harvard Health Publishing, 2021; Marieb and Hoehn, 2018). For example, small amounts of iron support hemoglobin and
bone growth, and zinc is important in wound healing and cellular metabolism (NIH, 2016; Harvard Health Publishing , 2021). Sometimes metallic elements work in tandem. For example, copper works with iron to help the body form red blood cells (National Library of Medicine, 2015b). The dietary sources of metals and the roles they play in health are summarized in Table 1.

Role in Health
Iron
Beans, chickpeas, dark chocolate, eggs, green leafy vegetables, iron-enriched bread and cereal, lean meat, liver, nuts, poultry, seafood, tofu. Crab, dairy products, fish, legumes, oysters, pork, poultry, red meats, whole grain products.
Is an essential component of hemoglobin; supports metabolism and bone growth; is necessary for growth, development, normal cellular function. Is important to numerous aspects of cellular metabolism, immune function, wound healing, and growth and development during pregnancy, childhood, and adolescence. Works with iron to aid in bone, hemoglobin, and red blood cell production; is important in healing and energy production; aids in iron absorption. Is needed for protein and fat metabolism, healthy immune system, nerve cells, and regulation of blood sugar; is required for normal bone growth, reproduction, and energy production. Is involved in glucose metabolism and cholesterol and protein synthesis. Is needed for nitrogen metabolism and the conversion of purines to uric acid. Plays critical roles in reproduction, thyroid hormone metabolism, DNA synthesis; is a vital antioxidant that protects the immune system by preventing the formation of free radicals; is necessary for pancreatic function and tissue elasticity. Is needed for calcium uptake to build strong bones; aids in building muscles and increasing testosterone levels; improves thinking skills and muscle coordination.
Zinc
Copper
Beans, cocoa, dried fruits, green leafy vegetables, nuts, organ meats, oysters and other shellfish, potatoes, whole grains.
Manganese Green leafy vegetables, legumes, nuts, seeds, tea, whole grains.
Chromium Basil, beef, brewer’s yeast, broccoli, grape juice, green beans, orange juice, potatoes, red wine, whole grain products. Molybdenum Beans, cereal grains, dark green leafy vegetables, legumes, peas. Selenium Beans, Brazil nuts, brown rice, chicken, dairy products, eggs, garlic, liver, muscle meats, organ meats, salmon, sardines, tuna, vegetables, whole grains.
Boron
Fruits, grains, leafy vegetables, nuts.
