A patient presents with pain from tooth 4.7 which is an abutment for a 4 unit bridge from 4.4 to 4.7. Clinical and radiographic examinations reveal tooth 4.7 has extensive distal caries and apical rarefying osteitis. The most appropriate initial management is to

remove entire bridge and assess restorability of abutments

perform endodontic therapy through the 4.7 crown

prescribe an antibiotic and an analgesic and reappoint the patient

section the bridge at 4.4, remove 4.7 crown and assess 4.7.

refrain from performing any exposure-prone procedures for a period of 3-6 months followed by a full series of hepatitis B vaccinations

receive one additional vaccination followed by post-immunization testing

repeat the full series of hepatitis B vaccinations followed by postimmunization testing
