Almost to the end of how to use the acronym LESION with the letter O for other structures.  This is where you describe if the lesion is effecting other structures and how it is effecting those structures.  The three main structures I am going to discuss are the teeth, mandibular…

Next is the internal structure of a lesion.  There are only three primary descriptions with this letter.  They are radiolucent, radiopaque and mixed radiolucent/radiopaque.
