Solid-head power toothbrushes retain less bacteria compared to hollow-head toothbrushes, according to researchers at The University of Texas Health Science Center at Houston (UTHealth) School of Dentistry, who found up to 3,000 times the bacterial growth on hollow-head toothbrushes The results of the study are published in the August issue of the Journal of Dental Hygiene. Lead author and professor at the UTHealth School of Dentistry, Donna Warren Morris, R.D.H., M.Ed., notes that microbial counts were lower in the solid-head toothbrush group than in the two hollow-head toothbrush groups in 9 out of 10 comparisons. The study was conducted over a three-week period where participants brushed twice daily with one out of three randomly assigned power toothbrushes. Participants used non-antimicrobial toothpaste and continued their flossing routine throughout the study, but refrained from using other dental products like mouthwash.
Salvatore Sauro, Professor of Biomaterials and Minimally Invasive Dentistry at University CEU Cardenal Herrera (CEU-UCH) in Valencia (Spain), has been working on an impressive research program where the main objective is the development of bioactive restorative and/or preventive materials with potential regenerative properties for dental tissues. Professor Sauro has more than 15 years of experience in dental adhesion, preventive and biomaterials research with more than 60 scientific articles in international peer-review journals, 1 international patent and 1 Brazilian patent. He has a wide international collaboration network with several centers of research and dental school around the world. His international and strong scientific reputation has allowed him to become visiting professor at the Federal University of Ceará, Brazil, where he is leading a research project for the development of innovative restorative materials with bioactive and anti-bacterial
