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

Which of the following is NOT a contraindication for the regular use of hydrogen peroxide?

1. Sponginess of gingiva

2. Root hypersensitivity

3. Staining

4. Demineralization

The correct answer is: Staining

The correct choice identifies that staining is not a contraindication for the regular use of hydrogen peroxide. Hydrogen peroxide is often utilized for its bleaching and antimicrobial properties, making it a popular choice for whitening teeth and improving oral hygiene. While it is true that hydrogen peroxide can sometimes lead to temporary staining issues, this is generally not considered a contraindication for its use. Instead, the benefits of hydrogen peroxide can outweigh this concern for those looking to achieve whiter teeth. In contrast, sponginess of gingiva, root hypersensitivity, and demineralization are conditions that may indeed warrant caution or avoidance when using hydrogen peroxide. Spongy gingiva indicates a potential underlying periodontal issue, and using a strong oxidizing agent like hydrogen peroxide could exacerbate inflammation. Root hypersensitivity suggests that the teeth are more vulnerable and could react negatively to the oxidative properties of hydrogen peroxide, leading to discomfort. Similarly, demineralization can indicate weakened enamel structures that may benefit from more protective treatments rather than aggressive agents like hydrogen peroxide that could further compromise the tooth structure. Therefore, identifying staining as not a contraindication provides clarity about the specific context and use of hydrogen peroxide in dental hygiene practices.
