This study looks at two different approaches to help pregnant people with gum disease get better dental care. Participants will receive free dental check-ups, cleanings, and supplies. The goal is to see which method reduces gum inflammation and improves oral health habits, and wh…

This trial asks whether GLP-1 receptor agonists, a class of drugs used for weight management, can improve gum health and boost the response to standard deep-cleaning treatment in people with obesity and periodontitis. Adults with both conditions will be split into two groups: tho…

This trial tests a new surgical technique that avoids cutting the gum tissue between teeth to repair deep bone defects caused by gum disease. The procedure uses a synthetic bone graft and a special gel to help the bone regenerate. The study includes 60 adults aged 35 to 65 with a…

This study investigates whether a daily probiotic lozenge containing Limosilactobacillus reuteri can reduce inflammation and improve gum health in adults with severe periodontal disease. Researchers will also analyze participants' oral and gut bacteria to identify who is most lik…

This study follows 100 adults who received short dental implants (7 or 8 mm) in the back part of the upper or lower jaw. Researchers want to see how well these implants hold up over 5 years by measuring bone loss, stability, and overall success. The goal is to determine if shorte…
