(19) Second, is it possible - by combining the two technologies of endoscopy and computers - to provide an individual patient with a short-term prognostic prediction sufficiently accurate to affect patient management.
(20) Computed tomography does not allow differentiation between these lesions and surrounding normal tissues.
Scaler
Definition:
(n.) One who, or that which, scales; specifically, a dentist's instrument for removing tartar from the teeth.
Example Sentences:
