Introduction: Understanding the bacterial flora in relation to the development of a disease is critical for evaluating the efficacy of various treatments. The bacterial profile around healthy periodontal and peri-implant sulci is still not clear. The purpose of this systematic review is to examine the specific microbiological variations between healthy periodontal and peri-implant sulci. Materials and Methods: A thorough search was conducted in electronic databases such as PubMed, Google Scholar, and Cochrane, as well as a manual search employing the eligibility criteria. After a thorough review, studies evaluating the microbial composition acquired from plaque samples obtained from patients with periodontal and peri-implant health were selected. Results and discussion: All 8 studies evaluated the differences in microbial profile in periodontal and peri-implant health. Out of them, 1 study suggested that tooth harbours more pathogenic bacteria than implants, 1 study claimed that healthy peri-implant sulci showed higher levels of anaerobic organisms than healthy teeth, while 4 confirmed no significant difference in bacterial profile around healthy teeth and implants. Also, 2 studies assessed the anaerobic bacteria count, 1 study suggested that anerobic count was higher around healthy implants and the other study was in favour of implants.  Conclusions: According to the existing studies, there is minimal evidence about the difference in microbial profile around natural teeth and implants in healthy state.
