The authors aimed to compare the incidence of oropharyngeal cancer (OPC) from 2011 through 2015 and the rate of human papilloma virus (HPV) vaccination from 2015 through 2017 in the United States overall and in Florida.
Using SEER*Stat software (Surveillance Research Program, National Cancer Institute), the authors calculated age-specific OPC incidence rates for various age groups and age-adjusted rates by sex and race to analyze Surveillance, Epidemiology, and End Results program and National Program of Cancer Registries data. The authors used Joinpoint software (Surveillance Research Program, National Cancer Institute) to model time trends of OPC incidence. They estimated the rate of HPV vaccination among teenagers in Florida and explored the main reasons parents gave for not getting their children vaccinated by means of analyzing data from the National Immunization Survey-Teen. The authors used the χ2 test to determine the association between sociodemographic factors and HPV vaccination and to compare the rate of HPV vaccination in the United States overall with that in Florida.
The incidence of OPC was higher and the rate of HPV vaccination was lower in Florida than in the United States overall. The OPC incidence rate was highest in those who were aged 50 through 70 years, non-Hispanic white, and male. The rate of being up-to-date on HPV vaccination in Florida was higher among female teenagers than male teenagers but did not differ significantly by other sociodemographic characteristics. The top reason for not getting an HPV vaccination in Florida was that it had not been recommended.
The authors found relatively higher and increasing incidence rate of OPC in Florida and lower rate of HPV vaccination among adolescents in Florida than in the nation overall.
The trends illustrated may stimulate policy changes to increase HPV vaccination for children and enhance the understanding of its benefits.
Two opposites make a whole
A single composite for cementation and core build-up
This has long been considered impossible, due to conflicting requirements. By
means of patented Active-Connect-Technology (ACT), however, dental specialists
Kettenbach Dental have succeeded in meeting the challenge without
compromising the material. The result is the Visalys® CemCore system, which
enables both adhesive cementation and core build-up to be achieved with just a
few components. Interlinking brands and the business.
Cementation composites need to be as hydrophilic as possible and highly fluid, whereas
core build-up requires a high degree of stability, and a material that swells as little as
possible. Kettenbach Dental has now developed a groundbreaking technology that
simply eliminates the conflicts: Active Connect Technology allows optimal mixing of the
somewhat hydrophobic cementation composite, Visalys® CemCore, with the hydrophilic
Visalys® Tooth Primer, on the damp surface of the tooth.
Despite its hydrophobic properties, the innovative composite achieves a high adhesive
strength without swelling. Visalys® CemCore flows superbly into every clearance, and
yet displays a high degree of stability: gentle application of pressure ensures the degree
of flow required when carrying out restoration, for example. Release the pressure, and
Visalys® CemCore reverts to its firm consistency so that excess material does not expand
and is easy to remove after application.
The Visalys® CemCore system incorporates three basic components: the composite
cement after which it is named, one single-component primer for teeth and another for
restoration. It is exceptionally convenient to use and can be tailored to the application:
Visalys® CemCore is available in the tried and tested automix syringe. The range of five
different colors (Universal, Translucent, Bleach, Opaque and Dark) ensures an excellent
basis for the aesthetic outcome. For securing restorations where outstanding aesthetics
are demanded, additional color-matched try-in pastes are available where required. The
Tooth Primer can be applied direct to dentine or enamel without mixing, and the
Restorative Primer is suitable for pre-treatment of all restoration surfaces.
This makes the Visalys® CemCore system suitable both for cementation and also for core
build-up using a single composite – the Active-Connect-Technology ensures powerful
adhesion with Visalys® Tooth Primer and Visalys® Restorative Primer, while low liquid
absorption ensures a high degree of dimensional stability in the core build-up and hence
a reduced risk of fracture in the final restoration. Visalys® CemCore is available to try in
Universal color with a starter pack, which includes not only the Visalys® CemCore but
also Visalys® Tooth Primer and Visalys® Restorative Primer, along with the required
