Searching for the last generation of adhesives
Miami, FL, USA: Peruvian doctors Gilberto and Natalia Henostroza presented two research papers on self-adhesive composite cements at the recent Congress of the International Association for the Dental Research (IADR).
Dr Natalia Henostroza presented a poster on the adhesive interface of composite cements, while her father focused on research on their sorption and solubility characteristics.
“Composite cements have changed tremendously, which has allowed us to see the future, the aim of the profession — not just cement-based resins but restorative materials, composite materials that won’t need adhesion,” explained Dr Henostroza, professor at the Universidad Cayetano Heredia in Lima, Peru.
Dr Henostroza wrote seven years ago in the first “Adhesion” book of the Latin American Association of Restorative and Dental Biomaterials (ALOYD) “that the last generation of adhesives will be the one in which adhesives won’t be needed. We won’t need one container or two container, but zero containers. They would be handled like glass ionomers.”
The investigator explained that it’s a joint research project between the University Cayetano Heredia and the University of Granada, Spain, which is led by Dr Manuel Toledano. University Cayetano Heredia also has research and exchange student programs with the University of Sao Paulo (Brazil).
The work of Dr Henostroza focused on changes in adhesive materials under the influence of moisture and on how much water they absorb, since a resin deteriorates by hydrolysis. “Solubility is also important because the material loses its adhesive properties,” concluded the researcher.
