What Needs to Be Completed Before Initiation of Orthodontic Treatment

What needs to be completed before initiation of orthodontic treatment for a client with multiple dental needs?

A) Dental caries and any endodontic pathology must be treated, dental hygiene periodontal debridement must be completed, and any areas of inadequate attached gingiva must be surgically corrected. Completion of periodontal surgery and prosthodontic therapy, if indicated, should be delayed until orthodontic treatment is completed.
B) Dental treatment, including the restoration of caries and endodontic therapy, dental hygiene, periodontal debridement, and surgical periodontal therapy, must be completed. Only prosthodontic therapy should wait until orthodontic treatment is completed.
C) All dental treatment, including the restoration of caries, endodontic therapy, nonsurgical and surgical periodontal therapy, and prosthodontic therapy, must be completed before orthodontic treatment.
D) All dental treatment except emergency treatment should be delayed until orthodontic therapy is completed because the relationships of the teeth will change dramatically during treatment.
