5. A 21 year old female presents for the first time to your practice. She is

very upset with the appearance of her upper left central incisor. On examination

A. Oral hygiene instruction and fluoride application

B. Excavation of caries and placement of a permanent restoration

C. Root-canaltreatment

D. Indirectpulpcapandrestoration

E. Direct pulp cap and restoration
