Accepted Answer

B)Smoking alters the body's ability to mount a host response at both the local and systemic levels by changes in vasculature.These changes manifest as reduced bleeding upon probing,potentially causing misinterpretation of periodontal health,and reduction of oxygen in the periodontal pocket,which may alter subgingival flora.

Question 3
