macule
an area that is usually distinguished by a color different from the surrounding tissue, it is flat and does not protrude above the surface of normal tissue. a freckle is an example of this
papule
a small circumscribed lesion usually less than 1mm in diameter that is elevated or protrudes above the surface of the normal surrounding tissue
pedunculated

sessile
describing the base of a lesion that is flat or broasd instead of stemlike
vesicle
a small, elevated lesion less than 1cm in diameter that contains serous fluid
nodule
a palpable solid lesion up to 1 cm in diameter founf in soft tissue it can occur above level with or beneath the skin

the elevation of a lesion by feeling it with the fingers to determine the texture of the area the descriptive term for palpation arc soft, firm semi/inn and fluid filled these terms also describe the consistency of a lesion

radiopaque
describes the light or white areas on a radiograph that results from the inability of radient energy to pass throught the structures the more dense the structure the more light or white it appears on the radiograph
root resorption
on radiograph when the apex of a tooth appears shortened blunted or irregularly shaped
scalloping aroung the root
a radiolucent lesion that extends between the roots as seen in a traumatic bone cyst this lesion appears to extend up the periodontal ligament
unilocular
having one compartment or unit that is well defined or outlined as in a simple radicular cyst
well circumscribed
term used to describe a lesion with boarders that are specifically defined and in which one can clearly see the exact margins and extent
