PERIODONTAL DISEASES

This study looks at whether vitamin D levels and supplements can reduce inflammation in people with gum disease (periodontitis or gingivitis). Researchers will measure markers of inflammation in blood and gum fluid before and after treatment. The study involves 120 adults with di…

This study tests whether adding special proteins or blood-based membranes to deep cleaning helps repair bone and gum damage from advanced gum disease. 88 adults with deep gum pockets and bone loss will receive one of three treatments or cleaning alone. Researchers will measure bo…

This study is testing whether a special laser device (FX-405) can improve the treatment of gum disease when used along with standard deep cleaning (scaling and root planing). About 70 adults with moderate to severe gum disease will receive eight 10-minute laser sessions over five…

This study tests whether a gel containing lovastatin, a cholesterol drug, can improve standard gum disease treatment. Researchers will compare the medicated gel to a placebo gel in 44 adults with periodontitis, including both smokers and non-smokers. The goal is to see if the gel…

This study tests a new surgical method for treating advanced gum disease. Instead of removing all inflamed tissue, the surgeon preserves the granulation tissue (the body's natural healing tissue) to see if it leads to better gum attachment and less bleeding. The trial involves 50…

This study compares three different surgical methods to treat gum disease (periodontitis). The goal is to see which technique best reduces deep gum pockets and helps gums reattach to teeth. About 60 adults with gum disease will be randomly assigned to one of the three procedures.…

This study tests whether a telehealth program can help cancer survivors prevent mouth sores, gum disease, and tooth decay. One hundred survivors who finished cancer treatment at least 6 months ago will either get the telehealth program or usual care. The goal is to see if the pro…

This study tests whether using a toothpaste with sodium bicarbonate (baking soda) and fluoride can help maintain gum health in adults who have already had non-surgical gum treatment. One hundred participants will use either the special toothpaste or a placebo for six months, whil…

This study tests whether a special dental gel (Livfresh) can improve gum health when used alongside standard deep cleaning. About 76 adults with moderate gum disease will brush with the gel twice daily for 6 months. Researchers will measure changes in gum pocket depth and bleedin…

This study tests two materials used to fill bone defects caused by gum disease: a collagen matrix and a bovine bone mineral. 80 adults with advanced periodontitis will receive one of the two during surgery. Researchers will measure changes in gum attachment and other healing sign…

This study tests whether adding injectable platelet-rich fibrin (i-PRF) to a standard bone graft helps fill in bone defects caused by advanced gum disease. Sixteen adults with stage III periodontitis will receive either the combo treatment or the graft alone during surgery. Resea…

This study is testing whether a simple online questionnaire can accurately assess a person's risk for gum disease (periodontitis or gingivitis). About 393 adults in Saudi Arabia will fill out the questionnaire and then have a dental exam to compare results. The goal is to see if …

This study compares two types of stitches (NOVOSYN quick and MONOSYN quick) used in gum surgery to see if they heal equally well. About 84 adults having gum surgery will be randomly assigned one of the two stitches. The main goal is to check early healing signs like skin regrowth…

This study tests whether using a microscope during gum surgery leads to better healing than standard dental loupes (magnifying glasses). About 25 adults with gum disease will take part. Researchers will check how well the gums heal and how long the stitching takes.

This study looks at how the types of bacteria in the mouth change in people with severe gum disease as they go from having some teeth left to having no teeth, and then after getting dental implants. Researchers will collect microbial samples and analyze DNA to see if different im…

This study follows 100 adults with healthy gums or various stages of gum disease over two years. Researchers will collect saliva and plaque samples at yearly visits to measure specific biomarkers. The goal is to see if these markers can predict who will develop or worsen gum dise…

This study looks at whether high uric acid levels (hyperuricemia) are linked to more severe gum disease and bone loss. Researchers will measure inflammation and oxidative stress markers in gum fluid and blood from 80 adults. Participants are grouped by gum health and uric acid st…

This study is checking how often the fungus Candida albicans shows up in the gums of 100 Syrian adults with periodontitis (serious gum disease). Researchers will collect plaque samples and measure gum health to see if the fungus is linked to more severe disease. The goal is to be…

This study looks at how oral hygiene habits and gum health affect quality of life in 160 adults. Participants will have a dental exam and fill out a questionnaire about how their mouth feels day-to-day. No treatment is given—the goal is simply to understand the connection between…

This study looks at how antibiotics like amoxicillin and metronidazole work in the body when used with deep cleaning for severe gum disease. Researchers want to find the best dose and treatment length (3 vs 7 days) to kill harmful bacteria without overusing antibiotics. About 45 …

This observational study at the University of Chile is examining whether a specific immune pathway (JAK1/2) is overactive in people with periodontitis, a common gum disease. Researchers will compare gum tissue from 30 healthy adults and those with inflamed gums to measure pathway…

This study looks at how the severity of pemphigus vulgaris, a chronic autoimmune skin disease, relates to gum health. Researchers will examine 20 adults with confirmed PV, measuring mouth sores and gum pocket depth, and comparing these with blood antibody levels. The goal is to u…

This study is looking at whether certain markers in blood and saliva can predict how well people with gum disease heal after non-surgical treatment. Researchers will measure these markers in 180 adults with healthy gums, gingivitis, or advanced periodontitis before and after trea…

This observational study in 46 people with severe gum disease aims to understand how two types of gum tissue (infra-osseous and supra-osseous granulation tissue) differ in their healing potential and infection-fighting properties. Researchers will collect tissue samples during pe…

This study looks at whether training medical staff and using electronic health records can encourage older adults (55+) on Medicaid to visit the dentist more often. About 929 participants from 12 primary care clinics will be split into two groups: one where doctors get extra trai…
