Does hiv cause acute necrotizing gingivitis very often?

Not necessarily: Hiv disease is usually quite controllable. Susceptibility to infection depends upon the degree to which the immune system is damaged, and this is estimated in HIV patients by the CD4 count and the ration between cd8 and cd4. Gingival infection is not commonly necrotizing, and progression to that stage suggests either a bad bug or ineffective treatment. See a good dentist, and an id doc.

HIV and ANUP: Hiv patient has low immunity and thus unable to combat the local microbial activity with low host reaction. As the result, bone loss and necrotizing of the tissue seen in the chronic situation of infection. Acute necrotizing uncerative periodontitis is seen more in HIV since chronic infection will lead straight to attachment loss (periodontitis) with minimal gum inflammation (gingivitis).
