Which source is considered credible for clinical guidelines among the following?

• A. Peer-reviewed journals
• B. CDC
• C. ADA
• D. Official clinical guidelines

Answer: (C)

Clinical guidelines are most credible when they come from a professional organization that uses a formal, evidence-based process to develop recommendations. The American Dental Association provides dentistry-specific guidelines developed by expert panels, with systematic literature reviews and peer review before publication. This focus on a transparent, field-relevant process makes ADA guidelines highly trustworthy for clinical practice in dentistry.

Peer-reviewed journals are excellent venues for high-quality research and may publish guidelines, but they are publications, not a single issuing body of official guidelines. The CDC offers broad public health guidance, and “official clinical guidelines” is too vague without naming the issuing organization. In this context, ADA is the most credible source for dental clinical guidelines.
