Sybele Saska, a doctoral candidate at the Institute of Chemistry (IQ) of UNESP, Araraquara campus, created a membrane that can replace current treatments to regenerate minor trauma to the teeth. The product is based on cellulose from Acetobacter xylinum, a micro-organism easily found in fruits and vegetables rotting.
Laboratory tests and a test pilot rabbits showed that the biomaterial retrieves bone tissue for a period 7-15 days, depending on the size of the damage. Only small bone defects can be treated with the film positioned on the traumatized area.
Lesions may be caused, for example, around a dental implantante in extraction processes when there is tooth or bone cysts. The biomaterial does not replace pins, plates and titanium screws.
The product was developed in about a year and a half, and his patent was filed in May, with support from FAPESP. Tests in mice are due in the first half of 2011.
The study Sybele Saska was considered the best dental materials in the category at the 88th General Session of the International Association for Dental Research in Barcelona, Spain.
