CASE A
This 54-year-old female is undergoing orthodontic therapy in response to temporomandibular disorder (TMD) . The maxillary orthodontic appliances were placed 18 months ago after an examination revealed various issues with malocclusion that were contributing to her chief complaint of temporomandibular joint (TMJ) pain and "sore jaws." (See Figure 6-31.)
-What is the most likely reason for the shortened appearance of the roots of the maxillary central and lateral incisors?

A) Use of the bisecting instead of the paralleling technique
B) External resorption possibly linked to the orthodontic movement of teeth
C) A development anomaly that caused incomplete root formation
D) Incorrect positioning that caused the roots to be located outside of the focus layer
E) Supereruption that resulted when painful TMD impeded the client's ability to occlude normally
