This study tested whether a synthetic gum graft (Mucogain matrix) could be a good alternative to the standard connective tissue graft for treating receding gums. The goal was to see if the synthetic option covers the exposed tooth root just as well, but with less pain and fewer c…

This study looked at whether taking probiotic tablets (Lactobacillus reuteri) twice a day, along with regular tooth brushing, could reduce gum inflammation in teenagers with braces. Only 3 participants were enrolled before the study was terminated early, so no meaningful results …

This study tested an experimental drug called HZN-1116 in 209 people with Sjögren's syndrome, an autoimmune disease causing dry eyes and mouth. The goal was to see if the drug could reduce disease activity and symptoms. The trial was terminated early, so results may not be availa…

This study tested a special dental material (Vitrebond) used to cover and protect the soft inner part of a tooth (the pulp) when it gets exposed due to deep cavities, injury, or dental work. The goal was to see if the material keeps the tooth alive and healthy for up to 5 years. …

This study looked at adding two immunotherapy drugs (ipilimumab and nivolumab) to standard radiation for people with advanced HPV-positive throat cancer. The goal was to see if the combination was safe and could shrink tumors better than radiation alone. The trial enrolled 37 par…

This study looked at 15 people with gum recession and worn-down teeth near the gum line. Some had the worn area rebuilt with a tooth-colored filling before standard gum surgery, while others had surgery alone. The goal was to see if rebuilding the tooth first leads to better cove…

This early-stage study tested a new oral drug, ASP5502, for primary Sjögren's syndrome, an autoimmune condition causing dry eyes and mouth. It involved 116 healthy adults and patients to check safety and how the body processes the drug. The study was terminated, but results may g…

This early-phase study tested a treatment using donated natural killer (NK) cells from cord blood, combined with chemotherapy, for children and young adults with solid tumors that returned or didn't respond to standard care. The goal was to find the safest dose and check for side…

This study tested a gel made from hyaluronic acid and amino acids (Gumblast) to see if it helps surgical wounds in the mouth heal better. It involved 28 adults who needed at least two teeth extracted, with one socket treated with the gel and the other left to heal normally. The t…

This study tested an experimental drug called vobramitamab duocarmazine in people with advanced prostate cancer and other solid tumors that stopped responding to standard treatments. The goal was to see if the drug could shrink tumors or slow cancer growth. The trial was terminat…

This early-phase trial tested whether N-acetyl cysteine (NAC) could help stem cells in damaged teeth grow roots to full maturity. The study planned to enroll up to 18 people with immature, infected teeth, but was terminated early with only 7 participants. Researchers used NAC as …

This study tested a peptide-based immunotherapy in 17 people with head and neck cancer who were scheduled for surgery. The goal was to see if the vaccine could boost the immune system's attack on cancer cells and to check for side effects. The trial was stopped early, but the res…

This early study tested a device that places radioactive seeds directly into skin, mouth, or soft tissue tumors. The seeds release alpha radiation to kill cancer cells from within. Only 2 people took part before the trial was stopped, so we don't have enough information to know i…

This study tested lithium disilicate crowns made with CAD/CAM technology in 8 adults with cavities or damaged teeth. The crowns were placed using different adhesive methods to check for sensitivity and quality. The trial was terminated early, so the findings are limited.

This study tested whether a special laser (Er,Cr:YSGG) can kill bacteria in root canals better than the standard rinse. 56 adults undergoing root canal treatment had their canals cleaned with either the laser or standard sodium hypochlorite. Researchers measured bacterial levels …

This study tested whether a special imaging technique called narrow band imaging (NBI) can help surgeons find early cancer spots in the mouth that are not visible under normal light. The trial involved 23 people with oral cancer who were already scheduled for surgery. Doctors com…

This study tested a dye called tozuleristide that makes oral cancer cells glow under special light during surgery. The goal was to help surgeons see and remove all cancer while sparing healthy tissue. The trial included 8 adults with oral cavity cancer or high-grade dysplasia. Th…

This study tested a new dental liner called Vitrebond™ Pulp Protect Liner/Base, placed under fillings to reduce tooth sensitivity after treating decay. It included 5 people aged 7 and older with moderate to advanced tooth decay. The liner was compared to a similar existing produc…

This study tested a morphine gel applied directly to painful mouth sores caused by chemotherapy. The goal was to see if the gel could relieve pain better than morphine given through an IV. The study included children and young adults aged 5 to 25. The gel was applied four times a…

This early-phase trial tested a new eye drop called rhPRG4 in 8 people with Sjögren's syndrome-related dry eye. Participants received either the active drop or a placebo, then switched after 90 minutes. The study measured eye dryness and safety over a single day. Because the tria…

This study tested whether a special oral care routine (dental cleaning and mouth treatment) could reduce severe mouth sores in people getting radiation for head and neck cancer. About 60 adults were planned to join, but the study was stopped early. The goal was to see if this app…

This study tested a monthly solution called Tangible Boost that is meant to restore a special coating on contact lenses. The goal was to see if it could improve comfort and vision in people with severe dry eye from Stevens-Johnson syndrome, Sjogren's syndrome, or graft-versus-hos…

This study looked at why people with mouth or throat cancer wait before seeing a doctor. Researchers interviewed 90 patients and asked them to fill out questionnaires about their feelings, thoughts, and social situation. The goal was to understand what factors cause the delay, so…

This study tested a new planning method to protect areas where dental implants could later be placed in patients receiving radiation for head and neck cancer. Researchers used virtual implant markers on CT scans to adjust radiation doses, aiming to keep implant sites safe without…

This study aimed to find out how many people with Sjögren's dry eye have reduced feeling in their cornea (the clear front part of the eye). Researchers measured corneal sensitivity, tear production, and pain in 103 adults with confirmed Sjögren's syndrome and dry eye. The study w…
