NCT07365865
Inadequacy of the attached keratinized tissue (\<2 mm) affects the long-term maintenance of prostheses and implants due to poor oral hygiene, plaque accumulation, inflammation, bleeding on probing, gingival recession , attachment loss, and crestal bone loss .Consequently, keratinized tissue augmentation is considered to compensate for keratinized attached gingival width inadequacy. Lack of keratinized tissue (KT) or KT with a narrow width (≤2 mm) compromise the long-term maintenance of peri-implant tissue health . Peri-implantitis was more frequently detected at dental implants sites with reduced width of KT than at those with adequate KT width. Free gingival graft (FGG) is regarded as an efficient method with significant clinical application . However, following harvesting larger grafts, some limitations arise in the donor site. Extensive palatal wound may cause discomfort and morbidity for the patient, the rugae area is unsuitable for graft material and the greater palatine artery will be of a great concern.
NCT07363031
Patients receiving radiotherapy for head and neck cancer often develop oral mucositis, a painful condition that causes redness and sores in the mouth. Oral mucositis can make it difficult to eat, drink, and speak, and may interfere with cancer treatment. Some viruses from the herpesvirus family, which commonly remain inactive in the body, may become active during cancer treatment and worsen mouth sores. However, the role of these viruses in oral mucositis is not fully understood. This study aims to understand whether herpesviruses present in the mouth are associated with the development and severity of oral mucositis in adults receiving radiotherapy for head and neck cancer. The study also evaluates whether taking an antiviral medication (valacyclovir) can reduce viral activity and improve mouth symptoms during treatment. Participants are randomly assigned to receive either valacyclovir or a placebo while undergoing radiotherapy. Samples from the mouth and saliva are collected at different time points before, during, and after radiotherapy to detect herpesviruses. Mouth sores are regularly examined, and pain levels are recorded throughout treatment. The results of this study may help clarify the role of herpesviruses in oral mucositis and support better strategies to prevent or manage this condition in patients receiving radiotherapy for head and neck cancer.
