Hi
Welcome to Just Answer
If the tools were not properly disinfected, then there are chances of transmission of HIV virus via dental procedures, if the tools were infectious with this virus.
To be sure about this, you can get yourself tested for HIV after 6 weeks, 3 months and then at 6 months.
If at the end of 6 months your test remain negative, that it is almost certain that you do not have the infection.
Always make sure that you receive sterilized instruments for any intervention.
I hope this clarifies and answers you.
Kindest Regards and Good luck.

Hello again.
A risk of HIV transmission exists if instruments contaminated with blood are either not sterilized or disinfected, or are used inappropriately between clients. This is a leading cause of HIV transmission in many countries. Needle sharing transmits the virus in similar way.
You can use either; Routine Elisa or Combo whatever available. Combo is new and carries a good sensitivity for HIV detection.
Kindest Regards and Good luck.
