b. Therapeutic
c. Clinical
d. Surgical
A
a. Laboratory
Laboratory tests, including blood chemistries, can provide information that contributes to a diagnosis. Therapeutic testing applies the principle of diagnosis based on clinical and historical information with confirmation by the response of the condition to therapy. Clinical diagnosis suggests that the strength of the diagnosis comes from the clinical appearance of the lesion. Surgical diagnosis is based on information about a lesion gained during surgical intervention.

Trying to establish the correct number of primary and permanent teeth present in a 7-year-old child may best be accomplished by which diagnostic component?
a. Clinical
b. Historical
c. Radiographic
d. Differential
c. Radiographic
A radiographic examination including intraoral and extraoral images would provide sufficient information to establish the correct number of teeth present. The clinical diagnosis would be adequate to view only the erupted teeth, not the unerupted permanent teeth. Some historical data might be helpful in this case but would not be considered the best diagnostic component. Enough information should be present in the clinical and radiographic examinations that a differential diagnosis is not necessary.
