Abstract: Objective: To evaluate the effect of FTA-DNA direct extraction method in the detection of peri-implantitis (PI) and periodontitis. Methods: Fourteen PI patients and 26 periodontitis patients were selected. Traditional method, boiling method, and FTA-DNA direct extraction method were used respectively to extract DNA. 16S-rDNA was amplified and gel electrophoresis was carried to compare the differences among three DNA extraction methods. Results: There was no significant difference between the peri-implantitis and periodontitis. DNA could be extracted by these three methods. FTA-DNA direct extraction significantly increased the success rate, when compared with traditional method and boiling method. Conclusion: Bacterial DNA in PI and periodontitis patients can be efficiently extracted and saved by FTA-DNA direct extraction method, which may be used to study and diagnose peri-implantitis and periodontitis.
