What are the three components of evidence-based dentistry?

• A. Dentist's expertise
• B. Scientific evidence
• C. Patient needs & preferences
• D. All three of the above

Answer: (D)

Evidence-based dentistry rests on combining three elements: solid scientific research, the clinician’s professional experience and judgment, and the patient’s needs, values, and preferences. The research provides the best available data on what works, for whom, and under what conditions. The clinician’s expertise is essential to interpret that evidence, judge its applicability to a specific patient, and carry out the chosen approach with skill and nuance. The patient’s values and circumstances ensure that decisions align with their goals, tolerance for risk and cost, and lifestyle, which affects adherence and satisfaction.

If you relied only on research without clinical judgment, you might misapply findings to a unique patient without considering practical nuances. If you leaned on the clinician’s experience alone, you could miss updates or higher-quality evidence. If you focused only on patient preferences, you might pursue options lacking solid evidence of effectiveness. Integrating all three leads to decisions that are scientifically sound, practically feasible, and personally acceptable.
