National Board Dental Hygiene Examination (NBDHE) Dental Hygienist Practice Test

Which ethnicity has a higher prevalence of periodontal disease?

1. Caucasian

2. Hispanic

3. African-American

4. Pacific Islander

The correct answer is: African-American

The choice that highlights a higher prevalence of periodontal disease among African-Americans is supported by various studies and health surveys. Research indicates that African-Americans tend to exhibit a greater incidence and severity of periodontal disease when compared to other ethnic groups. Factors that contribute to this disparity include socioeconomic status, access to dental care, and variations in genetic predispositions that may affect oral health. Data have consistently shown that African-American communities face challenges such as higher rates of untreated dental issues and a lower frequency of preventive dental visits. Additionally, cultural and lifestyle factors, including dietary habits and oral hygiene practices, may also play a role in the increased prevalence of periodontal disease. While it is essential to recognize that periodontal disease can affect individuals across all ethnic backgrounds, the statistics point towards a marked difference in impact and prevalence among African-Americans, making the selection of this ethnicity as having a higher prevalence particularly relevant in discussions surrounding public health and oral hygiene awareness.
