Objectives: To compare the oral microflora at implant and tooth sites in subjects participating in a periodontal recall program, to test whether the microflora at implant and tooth sites differ as an effect of gingival bleeding (bleeding on probing) or pocket probing depth. Material and methods: Data were collected from 92 implants and from all teeth at 38 subjects. The clinical evaluation was made by periodontal probing; the determination of the gingival bleeding index and microbiological examen of microbial species identification through the hybridization technique.
Results: A pocket probing depth ≥4 mm was found at 17,3% of t eeth and 21,3% of implant sites. T he d ental sites with a pocket probing depth ≥4 mm had a bacterial
load of 3,1 higher than the implant sites. No differences were found for the red, orange, green and yellow complexes. A higher total bacterial load was found at implant sites with a pocket probing depth ≥4 mm. atimplant sites, the bleeding on probing had no impact on bacterial load, but it influenced the bacterial load in dental sites.
Conclusions: The bleeding on probing and smoking had no impact on bacteria at implant sites, but it influenced the bacterial load in dental sites. The dental sites presented more bacteria than the implant sites with a comparable pocket depth. The subject factor is explanatory to bacterial load at both tooth and implant sites.
