Clinical trials

The goal of this prospective, randomized, single-blinded is to learn if there is an ideal sedation protocol in cataract surgery in adults. The main questions it aims to answer are: * Does the combination of Dexmedetomidine and Propofol affect significantly Ramsay sedation scale, compared to Dexmedetomidine and compared to Propofol? * How does each sedation protocol affect hemodynamics? (Heart rate and blood pressure) * Are respiratory events more common in a certain group? * Is the surgeon's satisfaction similar among groups? * Are adverse effects (bradycardia, hypotension, nausea) more common in a certain group? Researchers will compare 3 sedation protocols : Dexmedetomidine versus Propofol versus the combination of these 2 drugs and to see if one protocol is overall superior to the others. Fentanyl will also be used in all 3 sedation protocols. Participants will : * Receive one of these three protocols * Be operated for one or both eyes * Monitored during the whole surgery and in the recovery room * Be evaluated by the Ramsay sedation scale by a trained Anesthesiologist or CRNA during surgery and in the recovery room Surgeons will be asked about how much they were satisfied.

The goal of this clinical trial is to evaluate the isolated and combined effects of orofacial myofunctional therapy (OMT) and continuous positive airway pressure (CPAP) in adults with mild-to-moderate obstructive sleep apnea. The main questions it aims to answer are whether OMT alone, CPAP alone, or combined OMT plus CPAP improves obstructive sleep apnea severity at Week 12, as measured by the apnea-hypopnea index (AHI), and whether these interventions improve mandibular excursion. Researchers will compare 4 groups-sham plus standard of care, OMT plus standard of care, CPAP plus standard of care, and combined OMT plus CPAP plus standard of care-to assess differences in respiratory and anatomical-functional outcomes. Participants will be randomized to 1 of the 4 study arms. During the 12-week supervised intervention phase, participants will receive their assigned intervention together with standardized sleep-hygiene and lifestyle counseling. Assessments include sleep recording, mandibular excursion measurements, questionnaires on sleepiness and sleep quality, dento-occlusal and anthropometric measurements, and treatment adherence monitoring. After Week 12, participants will enter an observational follow-up phase through Week 52 to evaluate durability of treatment effects, treatment persistence, symptom recurrence, and clinically indicated treatment modifications.

Maxillary posterior area is the most challenging site for dental implant placement. Indeed, complex remodeling processes, resulting in changes of the maxillary sinus and shape of the alveolar ridge will cause difficulties in rehabilitating the posterior maxillae sites. Various techniques have been proposed in order to achieve the necessary bone volume for the placement of long term successful implants. However, unbalanced crown to implant ratio remains a risk factor after successful dental implants installation following sinus graft. No study on humans assessed the effect of apical positioning of the implants in posterior grafted sites (sinus graft or sinus graft + vertical GBR) on the following clinical parameters: The peri-implant bone remodeling (vertical bone loss (mm) and probing depth (mm) around the implants, crown bulkiness, emergence profile and crown height, and Patients satisfaction, food impaction (PROM)). This study will elucidate these points and based on the parameter's results, suggest a treatment based classification facilitating the treatment decision-making of the clinicians in case of an atrophic posterior maxilla; aiming to ensure a long-term successful supra-implant rehabilitation which will maintain its bio-mechanically and biological success.

This research aims to investigate the influence of alveolar ridge preservation, after extraction of maxillary posterior teeth, on the potential need of sinus floor augmentation procedures (that include lateral or crestal sinus augmentations). From peri-apical radiographs, maxillary posterior teeth will be divided into 4 groups according to the relationship of their apexes with the sinus. Then, the patients will be divided into 2 sub-groups: unassisted socket healing (only extraction) and ARP group (extraction + ARP) and their CBCT scans before implant placement will be collected. The CBCT scans should be at least 4 months post-extraction and ARP. Depending on the residual bone height, patients will be divided into 3 categories, according to the ABC classification: 1. In need of lateral sinus floor augmentation 2. In need of crestal sinus floor augmentation 3. No need for sinus floor augmentation, therefore, implant placement. These divisions will be conducted, according to: \- The residual bone height (RBH) which is the height in mm from the alveolar ridge crest to the lowest point of the maxillary sinus floor. The results of the proposed hypothesis are verified and interpreted after statistical analysis.

This randomized clinical trial aims to compare two behavior guidance techniques used to reduce anxiety in children during local anesthesia injections in dental treatment. The study evaluates the traditional Tell-Show-Do (TSD) technique versus an artificial intelligence (AI)-driven, avatar-based video method called the "Mini Dentist." Children aged 5 to 7 years who require local anesthesia for routine dental treatment will be randomly assigned to one of two groups. The control group will receive the conventional Tell-Show-Do explanation from the pediatric dentist. The experimental group will watch a short animated video featuring an AI-generated avatar that explains and demonstrates the procedure in a child-friendly manner before the injection. Anxiety and behavior will be assessed using heart rate monitoring, behavioral observation (FLACC scale), and a self-reported pain scale (Wong-Baker FACES). The goal is to determine whether the AI-based method improves cooperation and reduces anxiety compared to the traditional approach. Participation is voluntary, and all procedures follow ethical research standards.

The goal of this clinical trial is to learn whether temporary atrial pacing improves heart function after cardiac surgery under cardiopulmonary bypass (CPB). It will also help determine the best pacing rate during the first 24 hours after surgery. The main questions it aims to answer are: * Does atrial pacing improve cardiac output after surgery? * Is 70, 80, or 90 bpm the most effective pacing rate? * Does pacing reduce the risk of atrial fibrillation after surgery?

Our study hypothesizes that fluorescein exposure in diabetic patients with advanced chronic kidney disease results in deterioration of kidney function. It will therefore aim to evaluate the incidence of acute kidney injury induced by fluorescein in diabetic patients with CKD. The objective is to determine the incidence, severity and risk factors associated with this deterioration to improve the care of this specific population.

The hypothesis of our study: presence of a relationship between the type of anesthesia and complications after cardiac surgery. The aim is to assess the benefit of using intravenous or inhaled anesthesia on the patients\' stay and its complications.

The goal of this clinical trial is to learn if perioperative Transversus Thoracic Plane Block (TTPB) decrease perioperative pain after cardiac surgery. The main questions it aims to answer are: 1. does Transversus Thoracic Plane Block decrease perioperative pain after cardiac surgery more than the standard analgesic treatment? 2. Are the results different if the investigators perform Transversus Thoracic Plane Block before surgery or at the end of surgery?

this study is the first to demonstrate the efficacy of minimally invasive root canal treatment combined with intracanal heating and activation of NaOCl using a prototype needle on the healing of asymptomatic apical periodontitis of necrotic single rooted teeth. 32 teeth will be randomaly assigned into 2 groups :conventional and conservative technique .In the conventional group : each canal will be prepared using Reciproc Blue 25/08, approximetly 27 ml of NaOCl will be used , the canal will be activated using 20.02 taper tip of a sonic decive . This cyclel will be repeated 3 times and the obturation will be done using a single cone technique with AH plus resin-based sealer . In the second group a size 10 k file will be introduced to confirm patency and to record working length after filling the canal with NaOCl. A glide path will be established using the size 10 FlexoFile to the WL, than Proglider 16.02 to the foramen. After the glide path, the canal will be irrigated with 3 ml of 5, 25 % of NaOCL .The prototype needle tip will be placed in the canal to the length that is a little shorter than the length at binding point , in order to heat and activate the irrigant solution for 30 seconds.Step one is repeated 4 more times and a fresh solution of NaOCl is replaced every time. Canals will be dried using sterile paper points size 15 and the obturation will be performed for all teeth using the same technique as group 1 but with a standardized gutta percha point 2% tapered
