Bacterial Contamination of the Internal Cavity of Dental Implants After Application of Disinfectant or Sealant Agents Under Cyclic Loading In Vitro
Podhorsky, Anke / Putzier, Sven / Rehmann, Peter / Streckbein, Philipp / Domann, Eugen / Wöstmann, Bernd
The aim of this in vitro study was to evaluate the influence of two sealants (Kiero Seal, Kuss Dental, and Berutemp 500, Carl-Bechem) and a disinfectant agent (Chlorhexamed gel, GlaxoSmithKline) on bacterial colonization of the implant-abutment interface. Implants were pretreated with the substances or left without sealing before standard abutments were fixed. Half the specimens were subjected to cyclic loading, and the others were not loaded. Following 7 days of incubation in a bacterial solution, bacterial counts of the internal part of the implants were determined by real-time polymerase chain reaction. All pretreatments lowered bacterial counts, but no substance could guarantee sterility of the implants' internal portion.
