Abstract

Statement of problem. Lipopolysaccharide (LPS) affinity for titanium implant biomaterials could affect crevicular LPS concentrations and thereby influence periimplant inflammation. Purpose of study. The purpose of this study was to evaluate Porphyromonas gingivalis and Escherichia coli LPS affinity for titanium biomaterials groups that differed in surface oxide composition and surface roughness. Material and method. Polished and abraded grade 1 commercially pure titanium and grade 5 alloyed extra low interstitial titanium specimens were treated with 10 EU/mm² and radiolabeled LPS. Results. The resultant mean ± SD LPS adherence values ranged from 4.17 ± 0.29 to 4.79 ± 0.40 EU/mm². No difference in adherence and elution was indicated on the basis of LPS type, surface oxide composition, or surface roughness. Moreover, P. gingivalis and E. coli LPS desorption was below detection. Conclusion. Clinically, the high affinity of both LPS types of titanium biomaterials may adversely influence the periimplant tissue response. (J Prosthet Dent 1997;77:76-82.).
