Obstructive sleep apnea (OSA) is a sleep-related respiratory dysfunction. The prevalence of OSA is increasing with the increasing rates of obesity and elderly population worldwide. Perioperative anesthesia management should be adjusted to improve patient safety in patients with OSA. In OSA patients, positive pressure ventilation support may be required in the preoperative period, various ventilation strategies may be required in the intraoperative period, different pharmacologic agents may need to be avoided, and intensive care unit follow-up or noninvasive ventilation support may be required in the postoperative period. However, it is reported that a significant percentage of OSA patients remain undiagnosed. ASA (American Society of Anesthesiologists) has reported the criteria that should be questioned in order to determine the risk of patients in terms of OSA and to initiate the diagnostic process in risky patients and to make appropriate anesthesiologic arrangements in the perioperative period. In addition, the STOP-BANG assessment scale, which is widely used all over the world in OSA risk assessment, is also used in OSA risk assessment. It is thought that dental caries and extraction needs may be higher in OSA patients, especially since open-mouth sleeping accompanies the situation. In this respect, it is also important for patients to be diagnosed with OSA as it may prevent dental damage due to open-mouth sleeping in the future. Identifying patients at risk for OSA and directing them to the diagnostic process is very important for patient safety. Within the scope of the study, the criteria recommended by ASA and STOP-BANG score will be evaluated and recorded. Risk stratification in terms of STOP-BANG questionnaire and ASA criteria will be done separately for each patient and for each classification method. Patients at high risk will be consulted to the relevant medical department in the preoperative period for further investigation and treatment. In addition, it is aimed to correlate the risk levels determined in the study with postoperative respiratory complications and recovery time.

Dental caries is a major public health probleme the result of hard tissue demineralization and oral microbiota changes. Methanogenic archaea, mainly Methanobrevibacter oralis, are associated with various oral problems, including pathologies periodontal. Previous research has not really studied the Archaea in carious lesions, hence the importance of our study. Our study aims to explore their potential role in the the development of caries by analysing their prevalence and their quantification in relation to the carious risk individual. The aim is to improve understanding of the Cavity microbiology to advance management of this pathology in terms of prevention or of treatment. Our team is particularly competent in the field of Archaea, especially in the cultivation of Archaea methanogens since we have a dedicated platform. We also discovered the first human Nanoarchaea, opening up a whole new possible search field.

NCT07394751
The aim of this clinical study is to evaluate the performance of three different bioactive restorative materials against a composite resin for a period of 9 months. This randomized, split-mouth, single-center trial was performed on patients having occlusal caries (ICDAS 3 and 4) in both molars of the same jaw. The restorative materials used were Tetric N-Ceram Bulk-fill (control, Ivoclar Vivadent, Liechtenstein), Stela (SDI, Australia), Cention Forte (Ivoclar) and Activa BioActive Restorative (Pulpdent, USA). The restorations were evaluated at baseline, 3-6 and 9-month according to FDI-2 criteria, in terms of functional, biological, and aesthetic parameters, by two experienced evaluators.

Prevention of oral diseases is preferable to treatment and is the key method of achieving cost effectiveness for oral health improvement programs. Various preventive strategies for dental caries have been tried and are still being developed. The occlusal pits and fissures of posterior teeth are highly susceptible to caries because of the anatomy of pit and fissure surfaces, which favours stagnation of bacteria and substrates. Fissure sealing has been shown to be an evidence-based caries preventive method for protecting the occlusal surfaces against caries. Non- sealed teeth need to be restored approximately 50% more frequently compared to their sealed counterpart. Sealants are effective caries preventive agents as long as they remain bonded to teeth. It has been proposed that sealants should be placed on both sound teeth and incipient non-cavitated carious lesions on permanent teeth of high caries risk patients in order to prevent the onset of caries and its progression. According to the American Dental Association Guidelines for the use of pit and fissure sealants, ICDAS II codes 0, 1 and 2 are recommended for sealant application.A variety of dental materials have been used as sealants using different application techniques. Their effectiveness depends on the formation of a complete seal and is increased by correct technique and moisture control, appropriate follow-up and resealing as necessary. Resin-based conventional sealants are preferred choice, however use of phosphoric acid demineralizes the enamel layer and have elongated treatment time and is more technique sensitive.

NCT05096897
IBD patients have a higher risk of oral diseases that affect the oral mucosa, the teeth and the tooth supporting tissues. These conditions are often associated with pain, bleeding and impaired masticatory function which may have an impact on the oral health-related quality of life (OHRQoL). However, few studies have investigated the self-evaluation of oral quality of life in IBD patients. The rare existing studies focus on very specific patients (elderly patients, patients with stomas) and do not use validated tools for the evaluation of OHRQoL. We also lack data on the effect of treatments such as immunosuppressants and type of IBD on OHRQoL. The aim of this study is to (i) compare oral quality of life in a cohort of IBD patients versus non-IBD patients and (ii) explore potential factors that influence oral quality of life in IBD

NCT07262086
Introduction: Resin-based composites (RBCs) have become the gold standard in restorative dentistry due to their superior aesthetics, adhesion, and minimally invasive application. However, wear remains a critical drawback, compromising their longevity and clinical performance. Various techniques have been suggested to measure the clinical performance of (RBCs). Recent advancements in digital dentistry, such as intraoral scanning, offer a more precise and efficient approach for quantitative wear assessment. Aim: This study aims to evaluate wear resistance and bioactivity of self cured bioactive resin composite vs nanhybrid resin composite. Methodology: Twelve healthy patients with 24 carious molar teeth will be selected where each patient should have two oclusso- mesial cavities. Standardized oclusso- mesial cavities will be prepared for all the selected teeth, for each patient the first tooth will be restored with conventional nanohybrid RBC (M1). Meanwhile, the second tooth will be restored by self-cure bioactive RBC (M2). Then, wear resistance will be evaluated by intraoral scanner immediately after restoration (T0), six months later (T1), after 12 months (T2), 18 months (T3) and 24 months (T4). Software analysis will be done by superimposing the 3D digital impression and evaluate the restoration wear by calculating the 3D volume loss. Also, bioactivity of the restoration will be measured by measuring the mineral density beneath the restoration. Digital radiographic images will be taken for the restoration by parallel technique and grey scale of the pixels under restoration will be measured by software immediately after restoration (D0), one month later (D1) and after 3 months (D2).

Background This study is part of a doctoral research project at Universidad Cardenal Herrera CEU (Spain), directed by Prof. Santiago Arias de Luxán and conducted by doctoral candidate Shirli Kelmendi within the PhD program in Translational Medicine. Fixed orthodontic appliances complicate oral hygiene by creating retention areas that favor bacterial colonization and alter microbial balance. These conditions increase plaque accumulation and Streptococcus mutans (S. mutans) proliferation in saliva and plaque. The frequent low-pH environment favors aciduric bacteria such as S. mutans and lactobacilli, promoting enamel demineralization and formation of white spot lesions (WSLs) or cavitations. WSLs appear as opaque white areas due to subsurface mineral loss, mainly in the gingival third of the crown. They may develop as early as one month after bracket placement, while in patients without appliances, progression occurs after at least six months. Increased S. mutans levels have been reported as early as six weeks after treatment start. Risk factors include poor brushing, lack of floss or rinse use, time since last cleaning, and presence of caries or lesions. Intervention MI Paste Plus (GC, Japan) is a remineralizing cream with 0.20% sodium fluoride (900 ppm) and 10% CPP-ACP (RECALDENT™), providing calcium and phosphate stabilized by casein phosphopeptides. It has antibacterial and remineralizing effects, suitable during or after orthodontic treatment to prevent or reduce WSLs. Objective To evaluate whether MI Paste Plus during fixed orthodontic treatment reduces S. mutans counts in saliva and/or WSL incidence. Study Design A prospective, triple-blind, randomized clinical trial, approved by the Ethics Committee of the Ministry of Health of Albania and the Ethics Committee for Human Research of Universidad Cardenal Herrera CEU, Spain. The study will include 200 patients (100 per group) from two orthodontic clinics in Tirana, Albania. Participants will be stratified by age, risk level, and appliance type, then randomized by third parties. Outcome Measures Primary variables: S. mutans counts in saliva and number of WSLs after 3 months. Standardized saliva collection, culturing, and bacterial quantification ensure consistency. Clinical assessments will be performed at 1 and 3 months using QRay Cam Pro (Inspektor Systems, Netherlands) for quantitative fluorescence and ICDAS for visual inspection. Data will be analyzed using SPSS/R Commander software.
NCT07289022
This clinical study aims to investigate whether a single flowable composite resin system can achieve adequate color matching in posterior restorations and to compare it with a polychromatic composite system, which will serve as a control group. Clinical success will also be assessed using data obtained from the initial, six month, one-year, two-year, three-year, four-year, and five-year recall checks of the four different composite resin systems used in the study over a five-year period. L, a, and b parameters will be determined using the Vita Easyshade Compact (VITA Zahnfabrik, Bad Sackingen, Germany) Spectrophotometer device used in the study at the initial, half-year, one-year, two-year, three-year, four-year, and five-year intervals. Based on the obtained data, intraoral color changes will be determined using the CIEDE2000 color system. Each patient will be scanned with an intraoral scanner at each session. The hypothesis tested was that color matching and long-term clinical follow-up would be successful for all composite materials used in the study.

Digital technology is playing an increasingly important role in dentistry, because of its ability to support the practitioner and increase work efficiency. Among digital tools, orthopantomogram (OPT or panoramic) radiography is currently the most widely used. It provides a global view of the jaws, highlighting internal structures in 2D. As in other fields, scientific advances have made it possible to go beyond the limited representation of two planes of space and obtain 3D images. The intraoral scanner (IOS) or "optical impression camera" appeared in the mid-80s. They use light to create a digital optical impression that reproduces the surface of external anatomical structures in 3D images. It improves dental practice, making impressions less uncomfortable for patients, saving clinical time, facilitating storage and archiving, and facilitating transmission to the prosthetist where appropriate. This type of device is already well established in dental practices. More recently, Cone Beam Computed Tomography (CBCT) has also begun to develop. This 3D sectional imaging technique adds an extra dimension to the exploration of internal structures. Imaging examinations provide additional information to that obtained from the visual clinical oral examination. Together, they help the practitioner to establish the diagnosis and treatment plan. Currently, visual information has to be collected manually. Collecting this data represents a significant amount of information. Its quality and completeness are crucial to the success of the treatment. Given the high volume of consultations, and practitioners' need to optimize their time, it would be interesting to assess whether optical impressions, at least in part, could help to acquire this clinical data more systematically and more rapidly, in order to improve patient management. Similarly, Cone Beam CT (CBCT), with its 3D data, improves the accuracy of diagnostic information. It would also be interesting to assess the real added value of this examination. The RESTODATA-NUM study follows on from the RESTODATA study, the results of which provided recent information on the oral status of adult patients, and their care needs. The aim of this study is to compare the performance of a standard real-life examination by the practitioner combining clinical and radiographic examinations (referred to here as practitioner-on-patient detection) on the one hand, and an examination based on imaging results obtained using digital tools on the other, in terms of detecting dental condition in a sample of adult patients consulting for an oral examination at one of the participating centers.
