Which dental procedure should not cause significant bleeding in HIV patients?

The answer is correct because routine check-ups typically involve minimal intervention, mainly consisting of examinations and possibly superficial cleaning. These procedures do not generally affect the tissues significantly nor require any invasive techniques that might lead to substantial bleeding.

In contrast, extractions and deep cleaning procedures involve manipulating the gums and soft tissue more aggressively, which can increase the risk of bleeding, especially in patients with compromised immune systems, such as those with HIV. Minor restorative work can also be associated with more potential for bleeding compared to the relatively non-invasive nature of routine check-ups. Therefore, it is reasonable to conclude that routine check-ups would not cause significant bleeding in HIV patients.
