This completed study from Saudi Arabia surveyed 100 adult denture wearers about their knowledge of denture care and oral probiotics. Participants also had a dental exam and provided plaque samples to check for bacteria and fungi. The goal was to see how awareness and practices re…

This study looked at 101 adults with gum disease and bad breath to see if treating the gums could also improve their sense of smell. Participants received standard deep-cleaning dental treatment. Researchers measured bad breath gases and smell function before and one week after t…

This study looked at whether showing children pictures of healthy teeth or decayed teeth helps them learn to brush better. Sixty kids aged 7 to 14 received hands-on brushing lessons, some with positive images, some with negative images, and some with no images. Researchers measur…
