What defines clinical signs in a dental examination?
Symptoms described by the patient
Physical findings observed by an examiner
Imagery from radiographs
Findings from lab tests
The correct answer is: Physical findings observed by an examiner
Clinical signs in a dental examination are defined as physical findings that can be observed directly by an examiner. These signs may include visual observations, such as swelling, discoloration, or lesions, as well as tangible findings like tenderness or mobility of teeth. Unlike symptoms, which are subjective experiences reported by the patient, clinical signs can be verified through examination and do not rely on patient description. This objectivity is crucial in diagnosing dental conditions accurately. Imagery from radiographs and findings from lab tests can support the clinical examination but are not directly observable signs. They provide additional data to supplement the clinical findings but don't replace the importance of the physical observations made during the examination. Thus, the correct choice highlights the role of observable evidence in patient assessment and diagnosis.
