Periodontopathogen and Epstein-Barr Virus Contamination Affects Transplanted Bone Volume in Sinus Augmentation

Background: Bone microbial contamination can impair osteogenesis. Human herpesviruses-associated vasculitis can cause vascular damage within the osseous graft and host. This study is conducted to substantiate specific contamination and assess the impact 6 months after sinus augmentation.Methods: Culture- and polymerase chain reaction (PCR)-based identification were done on harvested bone particles and unstimulated whole saliva in a group of 30 patients undergoing maxillary sinus augmentation. Patients were divided into two groups: those with and those without a history of periodontitis. Radiographic evaluation was done to assess and compare bone healing and volume gain at baseline and 6 months post-transplantation.Results: Seventeen patients had a history of periodontitis, and 13 did not. Ten showed culture- and PCR-negative results and belonged to the periodontally healthy group. The 17 patients with periodontitis showed culture- or PCR-positive results for the targeted periodontal pathogens. Patients wi...
