NCT07551024
Some patients lose a large amount of bone in the upper jaw. When this happens, it can be difficult to place regular dental implants. In these cases, special implants called zygomatic implants can be used. These implants are longer than normal implants and are fixed in the cheekbone, which usually has enough bone to support them. They can help support fixed teeth for patients with severe bone loss in the upper jaw. Placing zygomatic implants requires careful planning and high accuracy. To help guide the surgeon during the operation, a surgical guide can be used. A surgical guide is a custom-made device that helps the surgeon place the implant in the planned position. Surgical guides can be made from different materials. The most common type is made from resin (a strong plastic material) using 3D printing. Recently, fully metallic surgical guides have been developed. These metal guides may be stronger and more stable during surgery, but it is not yet clear if they improve the accuracy of implant placement. The purpose of this study is to compare the accuracy of metal surgical guides and resin surgical guides when placing zygomatic implants in patients with severe bone loss in the upper jaw. Patients included in the study will undergo a clinical examination and a CT scan before surgery to plan the implant positions. During the surgery, each patient will receive zygomatic implants on both sides of the upper jaw. On one side, the implants will be placed using a metal surgical guide, and on the other side, they will be placed using a resin surgical guide. This allows the two types of guides to be compared in the same patient. After the surgery, another CT scan will be taken to check the final position of the implants. The planned implant position will be compared with the actual position after surgery to measure the accuracy of placement. The results of this study will help determine whether metallic surgical guides or resin surgical guides provide better accuracy when placing zygomatic implants. Participation in this study is voluntary. All patients will receive full information about the study and will sign a consent form before participating.
NCT04333537
This phase II/III trial studies how well sentinel lymph node biopsy works and compares sentinel lymph node biopsy surgery to standard neck dissection as part of the treatment for early-stage oral cavity cancer. Sentinel lymph node biopsy surgery is a procedure that removes a smaller number of lymph nodes from your neck because it uses an imaging agent to see which lymph nodes are most likely to have cancer. Standard neck dissection, such as elective neck dissection, removes many of the lymph nodes in your neck. Using sentinel lymph node biopsy surgery may work better in treating patients with early-stage oral cavity cancer compared to standard elective neck dissection.

NCT05964959
The goal of this cluster based intervention trial is to evaluate the effect of a nurse-led patient education program on dry mouth in patients with a life-limiting condition or frailty. The Mouth Educational Program (MEP) is a nurse-led patient education program, in which trained nurses use current clinical, palliative dry mouth guidelines in a structured manner to discuss causes, consequences and interventions with the patients and to create an appropriate treatment plan. This intervention will be compared to a control group receiving care as usual. Therefore, the main question it aims to answer is: Does a nurse-led patient education program reduce dry mouth complaints in patients with a life-limiting condition or frailty? Participants will be asked to answer questionnaires and, when part of the intervention group, partake in the Mouth Educational Program (MEP).
NCT07463469
This study was conducted at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tanta University. A prospective non-controlled clinical study was performed on ten patients with compromised zygomaticomaxillary bone. Surgical intervention was carried out using a customized surgical guide. Pre-surgical planning was performed using computed tomography (CT) scans for each patient. Surgical guides were fabricated using direct metal laser sintering technology. Zygomatic implants were inserted using a guided surgical protocol and specialized instruments. Postoperative CT scans were obtained to evaluate deviations between the planned and actual implant positions. Accuracy was assessed by superimposing the postoperative implant position onto the virtual pre-surgical implant plan using dedicated software. Descriptive and bivariate statistical analyses were performed.
NCT07456995
This clinical trial evaluates how different surface treatments on a metal base (Ti-Base) affect the success of dental crowns on implants. Patients receiving a zirconia crown for a missing lower back tooth are divided into three groups: one group receives no special treatment on the metal base, one group receives a silica coating, and the third receives both a silica coating and a chemical primer. The study monitors these crowns for one year to see which treatment best prevents the crown from coming loose or breaking, while also checking the health of the surrounding gums.
NCT05355792
This clinical study, funded by the company Dentsply Sirona, is being carried out to see if the newly developed tooth implant "OmniTaper EV" is safe, effective and functions as intended when replacing a lost or removed tooth. The OmniTaper EV implant is a further development of existing dental implants. It is made of titanium, a metal that is well tolerated by the human body, which has been successfully used in dental implants for more than 40 years. All components used in this study are available on the market, are CE-marked and will be used according to intended use and approved instructions. The study involves at 11 planned clinic visits including follow-up visits 6 months and annually until 5 years after installation of the permanent crown. after over a period of about five and a half years. The treatment method and healing period may vary depending on the individual case and treatment plan and additional visits may therefore need to be scheduled. The visits and procedures are the same as standard of care and no procedures will be done just for purpose of research. The study aims to recruit about 137 men and women from six clinics across Europe (Germany, UK and Switzerland) and participants can only receive one study implant each. Participation is entirely voluntary and participants can choose to withdraw from the study at any time, without giving a reason. The decision to decline or withdraw participation will not affect participants future treatment or care

The tested products were: * Listerine Total Care mouth rinse without alcohol. * Oral B Pro-Health Multi-Protection Mouth Rinse refreshing mint without alcohol. * Colgate total advanced pro-shield mouth rinse without alcohol. * Listerine Go Tabs. * Wrigley Extra White Soft Chew Peppermint chewing gum. The main questions it aims to answer are: Can the tested product lower the plaque formation? Can the tested product improve the mouth freshness and breath? Researchers will compare the tested products to not using any product (controls). Participants need to come for a screening appointment and sign a consent form at first. If they are eligible, they need to come 6 times to the clinic. On each day, they need to come twice (morning appointment at 8 a.m. and evening appointment at 4 p.m.). In the morning, they will have teeth cleaning and recieve one of the tested products to use on that day only (after tea break and lunch break), or they will recieve no product (control day). In the evening, participant's teeth will be stained and oral photos will be taken. They will be asked about their perciption of freshness and good breath after using the product.
NCT07402694
Periodontitis is a chronic inflammation caused by dental plaque that can destroy periodontal tissues. Current primary treatments include mechanical removal methods such as supragingival scaling and subgingival curettage. However, issues like microbial recolonization leading to inflammation recurrence exist, often necessitating the use of antimicrobial agents. Prolonged antibiotic use, however, can easily lead to bacterial resistance. Amphion oral rinse is a novel biomimetic material mouthwash. It inhibits plaque regrowth by forming a long-lasting physical barrier and avoids flora imbalance. Compared with traditional antibiotics, this product has shown unique advantages in the adjuvant treatment of periodontal diseases. This study aims to evaluate the efficacy of Amphion rinse combined with conventional periodontal therapy in patients with stage I-IV periodontitis, including plaque control and inflammation improvement. Additionally, it will analyze its impact on the oral microbiome and collect user experience feedback to provide a reference for its clinical application.

Oral potentially malignant disorders (OPMDs) are mucosal lesions that carry a risk of malignant transformation into oral cancer. Unfortunately, a general lack of knowledge and awareness of OPMDs is common among general dental practitioners. While thorough clinical examinations coupled with biopsy can identify most OPMDs, the absence of reliable non-invasive diagnostic tools and standardized risk stratification often delays early diagnosis and treatment of oral squamous cell carcinoma (OSCC).Early detection of suspicious oral lesions is crucial for reducing OSCC-related mortality and improving patient outcomes. Histopathological assessment of biopsied tissue remains the gold standard for diagnosis. However, since biopsy is invasive and may be associated with patient discomfort; numerous noninvasive diagnostic technologies have emerged to enhance the detection and diagnosis of oral mucosal lesions.Toluidine blue (TB) staining is one such adjunctive tool, where the degree of color retention aids in lesion characterization. Dark blue staining is considered positive for lesions highly suspicious for malignancy; light blue retention is considered positive for premalignant lesions pending histopathological confirmation, while lesions showing no stain retention are classified as negative.Exfoliative cytology represents another non-invasive diagnostic approach, wherein cells obtained via brushing the oral mucosa are spread on a slide for cytological evaluation. This technique, widely accepted and increasingly utilized, has proven valuable for early cancer detection. Notably, confocal microscopy has demonstrated high sensitivity and specificity (93%) in detecting malignant cells in exfoliative cytology specimens. Currently, TB staining and confocal microscopy remain the most commonly utilized non-invasive screening techniques in clinical practice.In recent years, artificial intelligence (AI) applications have shown remarkable promise in oncology, achieving high diagnostic accuracy across various cancer types. Deep learning models, in particular, offer exceptional performance, suggesting that AI-based solutions may be feasible for widespread community screening programs following further validation. In many cases, AI models have produced diagnostic outcomes that match or surpass those of experienced pathologists. Moreover, the combined application of AI with expert human evaluation has been shown to reduce diagnostic errors and improve diagnostic precision, particularly for poorly differentiated tumors and rare cases.Several studies have been done using different AI Models and revealed a promising application of AI in diagnosing OPMDs and cancers in different body sites.

Overall objective of this work is to develop better ways of detecting, diagnosing and measuring oral diseases and structures using light and optical approaches. All different areas of the mouth will be imaged, including healthy, diseased, dysplastic and malignant, as well as oral biofilm, and the imaging data compared against conventional diagnostic approaches such clinical and histopathological and molecular evaluations to (1) gain a better understanding of processes involved in oral pathology and (2) develop a combined patient specific, non-invasive method for the detection, diagnosis and screening of oral pathology and biofilm. Thus our goal is to identify and evaluate microstructural, metabolic, vascular, protein, genomic and metabolomics biomarkers of oral pathology can be used to detect, predict and map oral pathology, especially neoplasia. We are recruiting patients with a wide range of oral conditions including plaque, dry mouth, toothache, root canal treatments, gum disease, oral sores, dysplasia and cancer, autoimmune conditions and others as well as healthy control subjects. We will use a range of non-invasive imaging modalities to obtain information on the ways in which the oral health status affects optical properties, and determine means of detecting and quantifying these factors.. Imaging modalities to be utilized include: 1. Coherence and Doppler Tomography 2. Laser Speckle Imaging 3. Various forms of Spectroscopy 4. Fluorescence
