High Potential of Bacterial Adhesion on Block Bone Graft Materials.

Bone graft infections represent a challenge in daily clinics, resulting in increased patient discomfort and graft removal. The aim of this study was to investigate the initial adhesion of five representative pathogens on three different block bone graft materials (xenogeneic, alloplastic and allogeneic) and to assess if chlorhexidine (CHX) can effectively control the initial bacterial adhesion. Three different block bone grafting materials (Tutobone®, Endobon® and human spongiosa) were incubated with , , , and in the presence or absence of 0.

Integrity of dural closure after autologous platelet rich fibrin augmentation: an in vitro study.

Background: Watertight closure of the dura mater is fundamental in neurosurgery. Besides the classical suturing techniques, a variety of biomaterials have been proposed as sealants. Platelet rich fibrin (PRF) is an autologous biomaterial which can readily be obtained through low-speed centrifugation of patient's own blood.

Effect of thrombosis-related gene polymorphisms upon oral cancer: a regression analysis.

It is well-known that there is an interplay between hemostasis, thrombosis and cancer. Functional DNA polymorphisms in genes encoding factors related to thrombosis have been associated with increased risk for oral squamous cell carcinoma (OSCC). The present study investigated the possible combinatory effect of 10 such polymorphisms as primary risk predictors for OSCC in a European population.

Prevalence of human papillomavirus in saliva and cervix of sexually active women.

Objective: Human papillomavirus (HPV) is strongly associated with cervical cancer and possibly with some oropharyngeal cancers. However, the relation between oral and cervical HPV infection is not fully understood. This study evaluates the prevalence rate and type-concordance of HPVs in these areas.
