This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Braces can make teeth straighter and result in a healthier looking smile But can they prevent tooth decay? New research says no Many people think braces early in life can help avoid future tooth decay Because people think straighter teeth are easier to brush But a study at the University of Adelaide found no proof of this The team followed more than 400 teens for 17 years—over 1/3 of whom had received braces By age 30, there was no difference in the number of decayed teeth between those who had received braces and those who had not Greater numbers of decayed teeth were strongly linked to brushing less than twice a day While the study focused on one Australian city, the message does appear clear To avoid tooth decay, there’s no better advice than brushing twice a day Doğramacı EJ and Brennan DS. “The influence of orthodontic treatment on dental caries: An Australian cohort study.” Community Dentistry and Oral Epidemiology (2019).
