Introduction
Recent past has seen a tremendous increase in demand for dental implants. Dental implant failures have been a major drawback for scientists in this field. In many instances dental implant failures has been occasioned by an inflammatory disease called Peri-implantitis .Due to the complexity of the microbiota that cause PI, it has been extremely hard to pin down this dental disease. The microbiota responsible for this disease has for a long time remained inscrutable to medics and scientists. This is because the composition of the microbiota causing PI is similar to that of our teeth. Therefore, identification of micro organisms is very empirical to the authors in order to come up with solution or possible treatment to PI. It is after the authors have identified the microorganisms that they can study their composition and characteristics and consequently work on methods to kill the microorganisms and that way provide treatment for PI.
The basic objective of this research was to discover or identify the microbiota present in subjects with Peri-implantitis. Analysis of the results found that the authors were actually able to answer the questions that prompted their research. It was found that the main source of bacteria that infect implants was mainly the plaque in saliva or residue teeth. The microbiota that is around implants also tends to display similar traits to the one in residual teeth. A total of eight sites were analyzed during the research. There were three PI sites, three periodontitis sites and two healthy implants. The total number of bacterial species that were identified in the three sites was as follows; periodontitis (57), PI (77) and periodontal healthy implants (12).These organisms were later classified into different clusters in accordance to the phylum-level grouping. The authors were able to confirm that the microbiota for PI included Gram positive bacteria which exhibited more diversity than that of periodontitis or healthy implants. They were able to identify various PI microbiota and to name a few; Parvimonas micra, Pseudoramibacteralactolyticus and Peptostreptococcus stomatis. It was only the Chloroflexi, Synergistetes and Tenericutes phyla that were found at the PI sites and these were established as plausible candidates for the PI disease.
