Comparative clinical evaluation of the stability of implants using double acid etching treatment with and without the addition of fluoride solution: A randomized clinical trial.

Background: Osseointegration depends on primary stability, and further, implant surface modifications may improve secondary stability. This randomized clinical trial evaluates whether adding a fluoride solution enhances the implant stability.

Materials And Methods: Stability of dental implants with two different types of surface treatments was compared utilizing resonance frequency analysis (RFA).

HPV DNA/RNA detection in various oral and oropharyngeal biomaterials identifies active HPV infections also in non-neoplastic tonsils.

Previous studies describe a correlation between HPV-positivity and non-smoking in TSCC; p16-expression as surrogate-marker for HPV-DNA/RNA-positivity is discussed controversially. In the present study, these parameters are assessed prospectively. HPV-status of sputum and tonsillar-swabs was analyzed to determine their validity as surrogate-marker for tissue-HPV-status.

No association between HPV-status in tonsillar tissue and sexual behavior of the patients in a northern German population - Critical view of the link between HPV natural history and HPV-driven carcinogenesis.

HPV-infection in patients with HNSCC is reportedly correlated with sexual behavior, age, and tobacco/alcohol-consumption. HPV-infections of the oral cavity are regarded as sexually transmitted. Comparable data of patient populations outside the U.

Focal drug administration via heparin-containing cryogel microcarriers reduces cancer growth and metastasis.

Developing drug delivery systems that release anticancer drugs in a controlled and sustained manner remains challenging. We hypothesized that highly sulfated heparin-based microcarriers would allow electrostatic drug binding and controlled release. In silico modelling showed that the anticancer drug doxorubicin has affinity for the heparin component of the microcarriers.
