# One of the following procedures falls under high bacteremia risk for infective endocarditis: 
a. Post-operative suture removal 
b. Intraligamentary and intra-osseous local anesthetics injections 
c. Intracanal endodontic treatment 
d. Placement/ removal of removable orthodontic appliances 


The correct answer is B. Intraligamentary and intra-osseous local anesthetics injections.

All dental procedures that involve manipulation of gingival tissue or the periapical region of teeth or perforation of the oral mucosa are the procedures for which endocarditis prophylaxis is reasonable.

The following procedures and events do not need prophylaxis: 
  • routine anesthetic injections through noninfected tissue,  
  • taking dental radiographs, 
  • placement of removable prosthodontic or orthodontic appliances, 
  • adjustment of orthodontic appliances, 
  • placement of orthodontic brackets, 
  • shedding of deciduous teeth, 
  • and bleeding from trauma to the lips or oral mucosa.
