Clinical trials

The aim of this study is to evaluate the feasibility and preliminary effects of PrevED MR, a group-based preventive intervention for adolescents and young adults at risk of developing eating disorders. PrevED MR is based on dialectical behavior therapy skills and uses mixed reality and virtual reality activities to support emotion regulation, mindfulness, distress tolerance, and body-related acceptance. Participants will be randomly assigned to either the PrevED MR intervention group or a waiting-list control group. The intervention will be delivered over 6 weeks, with two sessions per week, for a total of 12 sessions. Assessments will be conducted at baseline and after the intervention to examine changes in eating disorder symptoms, body image acceptance, emotion regulation strategies, rumination, usability, sense of presence, cybersickness, satisfaction, and adherence.

The goal of this clinical trial is to evaluate whether two different techniques for treating palatal wounds-sutures and cyanoacrylate bioadhesive-can influence postoperative morbidity, clinical healing, and soft tissue dimensional changes in patients undergoing epithelialized gingival graft harvesting from the palate. The main questions it aims to answer are: Does the use of cyanoacrylate bioadhesive reduce postoperative morbidity compared to sutures? Does the choice of wound treatment technique affect clinical healing and three-dimensional changes in soft tissues? Researchers will compare the sutures (control group) to the cyanoacrylate bioadhesive (test group) to determine if the bioadhesive leads to improved postoperative outcomes. Participants will: Undergo epithelialized gingival graft harvesting from the palate. Receive either sutures or cyanoacrylate bioadhesive for wound closure. Be monitored for postoperative morbidity, clinical healing, and soft tissue dimensional changes.

This prospective observational cohort study aims to investigate the association between maternal musculoskeletal factors of the hip, lumbopelvic, abdominal, and pelvic floor regions and childbirth outcomes, as well as their consequences on pelvic floor function during the postpartum period. A total of 376 pregnant women will be recruited at 36 weeks of gestation and followed until 12 weeks postpartum. Musculoskeletal assessments will include hip range of motion, lumbopelvic mobility, abdominal muscle function, and pelvic floor strength and morphology. Obstetric outcomes such as mode of delivery and perineal trauma will be recorded after childbirth. The study will analyze whether maternal musculoskeletal function during late pregnancy is associated with delivery mode and pelvic floor dysfunction in the postpartum period.

This randomized, double-blind, split-mouth clinical trial evaluates the effectiveness of at-home dental bleaching using customized nightguards fabricated by digital (3D-printed CAD-CAM) and conventional methods, with and without reservoirs. Adult participants with good general and oral health and a baseline tooth shade of A2 or darker undergo bleaching with 10% carbamide peroxide. Outcomes include tooth color change (subjective and spectrophotometric measures), tooth sensitivity, gingival irritation, patient comfort, and patient satisfaction over time.

This randomized clinical trial aims to evaluate the clinical performance of a 3D-printed hybrid resin (VarseoSmile TriniQ) used for indirect restorations in endodontically treated teeth, compared with a CAD/CAM composite block (Cerasmart). In addition, two different luting protocols will be compared: a preheated microhybrid composite (Enamel Plus HRi) and a resin cement (RelyX Universal). Sixty patients requiring restoration of an endodontically treated molar with an indirect adhesive overlay will be recruited at the University Dental Clinic of the Universitat Internacional de Catalunya (Barcelona, Spain). Participants will be randomly assigned to receive restorations fabricated either using the printed hybrid resin or the CAD/CAM composite material. Each material group will be further divided according to the cementation technique used. All restorations will be fabricated following a digital workflow that includes intraoral scanning, CAD design, and either additive manufacturing (3D printing) or subtractive milling. Adhesive luting procedures will be performed according to standardized clinical protocols. Clinical evaluations will be performed at baseline, 3 months, 6 months, and 12 months, and annually thereafter. The clinical performance of the restorations will be assessed using modified United States Public Health Service (USPHS) criteria, including parameters such as marginal adaptation, contact points, color stability, wear, fracture occurrence, secondary caries, and patient comfort. The results of this study will provide clinical evidence regarding the behavior of 3D-printed hybrid resin restorations and their potential use as an alternative to conventional CAD/CAM composite materials for indirect restorations in endodontically treated teeth.

This prospective clinical study compares two cementation techniques for implant-supported zirconia fixed partial dentures on titanium bases (Ti-bases): extraoral cementation performed on the working model and intraoral cementation performed chairside. Thirty clinical cases with two osseointegrated implants requiring a multi-unit zirconia restoration will be recruited at the UIC Dental Clinic. For each case, two restorations with identical design will be produced: one will be cemented extraorally (control) and an identical replica will be cemented intraorally (test). Micro-deformation will be assessed as peri-implant microstrain (µε) using a standardized strain-gauge setup and the same recording protocol for both techniques. The primary analysis compares microstrain between intraoral and extraoral cementation within each case; implant/prosthetic events will be recorded descriptively.

This multicenter prospective observational feasibility study evaluates the implementation of the RAPHAEL model, a remote monitoring palliative care approach for patients with heart failure. The study aims to assess the feasibility, acceptability, usability, and implementation outcomes of integrating structured remote symptom monitoring and palliative care needs assessment into routine outpatient heart failure care. Adult patients with heart failure and worsening symptoms and/or potential palliative care needs will complete a structured digital questionnaire during a 4-week follow-up period. Healthcare professionals will review reported needs and conduct follow-up contact according to usual clinical practice. No experimental drugs or devices are administered, and clinical management remains at the discretion of the treating team. Primary outcomes focus on feasibility and implementation metrics, including participation rates, acceptability, usability, perceived burden, resource requirements, fidelity to the intervention model, training adoption, applicability, adaptation, and demand.

This study aims to evaluate the level of knowledge regarding periodontal disease and its association with periodontal health status among health sciences students. An observational, cross-sectional, analytical, and comparative design will be conducted involving two cohorts: final-year Dentistry students and Psychology students from the Universitat Internacional de Catalunya (UIC). A total of approximately 60 participants (30 per group) will be recruited using stratified random sampling. Eligible participants must be at least 18 years old and provide written informed consent. Students who have received periodontal treatment within the previous six months, present uncontrolled systemic diseases, or are pregnant or breastfeeding will be excluded. Data collection will take place during a single clinical visit between January and April 2026 and will consist of two phases. First, participants will complete a validated Knowledge, Attitudes, and Practices (KAP) questionnaire assessing understanding of periodontitis, attitudes toward oral health, and daily oral hygiene behaviors. Knowledge scores will be categorized into low, medium, and high levels. Second, a comprehensive periodontal examination will be performed by a certified periodontist under standardized conditions, including plaque index, bleeding on probing, probing depth, gingival margin position, clinical attachment loss, and radiographic assessment. Periodontal status will be classified according to the 2018 EFP/AAP classification system using staging and grading criteria. The primary outcome is the presence of periodontal disease (gingivitis or periodontitis). The main independent variable is the level of knowledge about periodontitis. Covariates include age, sex, oral hygiene habits, smoking status, perceived stress, and self-reported systemic conditions. Statistical analysis will be conducted using SPSS, Stata, or R software. Descriptive statistics will summarize participant characteristics. Bivariate analyses will assess associations between knowledge level and periodontal disease using chi-square tests and appropriate parametric or non-parametric comparisons. Multivariate binary logistic regression will be applied to evaluate whether lower knowledge levels are independently associated with a higher prevalence of periodontal disease, adjusting for relevant covariates. Statistical significance will be set at p \< 0.05. The study will be conducted following ethical approval from the UIC Research Ethics Committee. Participation will be voluntary, confidentiality will be ensured through anonymized data handling, and participants diagnosed with periodontal disease will be referred for appropriate periodontal care.

This clinical trial investigates the biological and clinical outcomes of immediate implant placement in aesthetic areas presenting with buccal bone dehiscence. Traditionally, these defects are treated with a bone graft and covered using a collagen membrane; however, there is ongoing debate about whether the membrane is necessary for optimal regeneration. This study proposes the use of a connective tissue graft instead of a collagen membrane, aiming to improve soft tissue volume and aesthetics without compromising bone healing. The objective of the study is to evaluate whether the use of an autogenous connective tissue graft in combination with a deproteinized bovine bone mineral with collagen (DBBM-C) achieves results that are not inferior to the conventional protocol that uses DBBM-C and a collagen membrane. The main outcome variable is the vertical buccal bone gain measured after twelve months of healing. The study design is a randomized controlled clinical trial including twenty-four patients divided equally into two groups. Each participant will attend eight follow-up visits over twelve months. After atraumatic tooth extraction, immediate implants (BLC, Straumann) will be placed using a prosthetically guided protocol. Buccal dehiscence will be measured intraoperatively, and a partial-thickness tunnel flap will be prepared to allow soft tissue adaptation and graft placement. In the control group, the defect will be filled with DBBM-C and covered with a collagen membrane stabilized with horizontal mattress sutures. In the test group, the defect will receive DBBM-C covered by a connective tissue graft harvested from the palate and fixed in a similar manner. When primary stability is equal to or greater than 35 N/cm, an immediate screw-retained provisional crown will be delivered; if stability is lower, a customized healing abutment or Maryland-type provisional will be used instead. After three months, digital impressions will be taken to fabricate the definitive zirconia restoration. All restorative steps will be performed by experienced clinicians using a standardized digital workflow. Patients will follow routine postoperative care instructions, including soft diet and restricted brushing in the surgical area for one week. The main benefits of this study include advancing the understanding of regeneration strategies for buccal bone dehiscence and improving clinical decision-making in immediate implant protocols. Participants are also expected to benefit from implant-supported rehabilitation, functional restoration, and aesthetic improvement. The potential risks are minimal and limited to typical surgical complications such as discomfort, swelling, or minor infection, which will be managed following established clinical protocols. If a patient declines participation, conventional implant treatment will be offered, or alternative prosthetic options such as fixed or removable restorations will be provided. Any intra- or postoperative complications during the study will be treated promptly and documented according to institutional standards. The biomaterials used include BLC Straumann implants, Bio-Oss Collagen (DBBM-C), Bio-Gide collagen membranes, and appropriate suture materials. Procedures will employ standard periodontal and tunneling instruments, as well as a digital intraoral scanner for accurate prosthetic fabrication. Statistical analysis will involve descriptive and inferential methods. The Kolmogorov-Smirnov test will assess normality, and mixed ANOVA models will evaluate differences between groups and across time points. Covariate adjustment will be performed using ANCOVA when necessary, and intra- and inter-examiner reliability will be tested with the intraclass correlation coefficient. The level of statistical significance will be set at 0.05. The expected outcome is that the use of an autogenous connective tissue graft will demonstrate bone regeneration results equivalent to those obtained with a collagen membrane, while potentially improving soft tissue thickness and aesthetic integration. This finding would support the clinical use of soft tissue grafts as an alternative to collagen membranes in immediate implant placement within aesthetic regions showing buccal dehiscence. All study procedures follow the principles of the Declaration of Helsinki and ethical standards for human clinical research. Participants will receive detailed information about the study protocol and will sign informed consent before inclusion. In summary, this study aims to determine whether a connective tissue graft can safely replace a collagen membrane in the management of buccal dehiscence during immediate implant placement, offering comparable regenerative outcomes with possible superior soft tissue aesthetics.

This study aims to compare 2 different groups of patients with both a healed site in the upper posterior sector after extractions, one treated with ultra-short implants, and another with long implants with bone regeneration. The objective is to evaluate if short-implants are superior in terms of better clinical outcomes, survival rates and safety, reduced surgical time, postoperative discomfort, and complication risk compared to conventional implants and bone regeneration.

This prospective cohort study aims to evaluate patient-related, psychological, and clinical factors influencing postoperative pain following gingival graft harvesting from the palate. Consecutive adult patients requiring mucogingival surgery for root coverage or soft tissue augmentation around teeth or dental implants will be recruited at the Clínica Universitària d'Odontologia of Universitat Internacional de Catalunya (Barcelona, Spain). All participants will undergo standardized pre-surgical periodontal care and oral hygiene instruction prior to surgery. Gingival grafts will be harvested from the palate under local anesthesia using a standardized surgical technique. Postoperative management will include analgesic medication, antiseptic rinses, and standardized postoperative instructions. Patient-reported outcomes will be collected using validated questionnaires to assess anticipated pain, postoperative pain, stress, dental anxiety, psychological profile, personality traits, pain catastrophizing, coping strategies, oral health-related quality of life, and analgesic consumption. Postoperative pain and discomfort during eating will be recorded daily for two weeks. Clinical variables, including palatal thickness, graft dimensions, operative time, operator experience, and donor-site wound healing, will also be assessed. The primary outcome is postoperative pain intensity following palatal graft harvesting. Secondary outcomes include operative time, donor-site discomfort, oral health-related quality of life, analgesic consumption, psychological and behavioral factors, and donor-site healing. The results of this study aim to improve understanding of factors associated with postoperative pain and to support individualized patient management in mucogingival surgery.

This randomized clinical trial aims to evaluate and compare the efficacy of different interproximal oral hygiene devices for biofilm removal around posterior single dental implants in patients diagnosed with peri-implant mucositis. Peri-implant mucositis is a reversible inflammatory condition of the peri-implant soft tissues caused primarily by bacterial biofilm accumulation. Effective plaque control is essential for the prevention of disease progression to peri-implantitis. However, there is limited clinical evidence regarding the comparative effectiveness of different interproximal oral hygiene devices in implant-supported sites. A total of approximately 75 patients with posterior single implants and peri-implant mucositis will be recruited. Participants will be randomly allocated to one of the study groups, each using a specific interproximal oral hygiene device as part of their daily oral hygiene regimen. All participants will receive standardized oral hygiene instructions at baseline. Clinical parameters related to peri-implant inflammation and plaque accumulation will be assessed at baseline and at follow-up visits at 1, 3, and 6 months. The primary outcome is the reduction of peri-implant biofilm accumulation. Secondary outcomes include changes in clinical inflammatory parameters around the implants. The results of this study are expected to provide clinically relevant evidence to support evidence-based recommendations for interproximal oral hygiene in patients with dental implants affected by peri-implant mucositis.

This study evaluates the clinical performance, marginal integrity, surface wear, color stability, and postoperative sensitivity of graphene-reinforced CAD/CAM indirect restorations (inlays, onlays, overlays) in molars affected by moderate to severe Molar-Incisor Hypomineralization (MIH) in adolescents. A total of 30 patients aged 10-16 years will receive minimally invasive indirect restorations fabricated from a nano-reinforced graphene polymer (G-CAM®). Clinical outcomes will be assessed using FDI criteria, VAS sensitivity scores, patient satisfaction, and digital 3D scans over a 12-month follow-up. The study aims to determine clinical acceptability and safety compared with historical outcomes reported for composite and lithium-disilicate indirect restorations.

Simulation is a cornerstone of health sciences education, with debriefing being its most critical component for fostering clinical skills. While various debriefing styles exist, there is limited evidence comparing the effectiveness of instructor-centered (ICT) versus learner-centered (LCT) approaches, specifically on the development of clinical judgment in nursing students.

The purpose of this study is to evaluate the clinical results in pain intensity, neck disability, range of motion, endurance deep cervical muscles, forward head position and kinesiophobia through thoracic spine mobility, deep neck muscles and thoracic strength training and pain education protocol versus a thoracic spine mobility, thoracic strength training and pain education protocol in patients with chronic non-specific neck pain.

Introduction and Significance: Preventive interventions have been shown to reduce the risk of developing anxiety and depression, making them a critical focus area in mental health promotion for children and adolescents. Enhancing emotion regulation (ER) skills in young people is one approach to preventing anxiety and depression, as ER involves cognitive processes of modifying thoughts and behaviors to manage emotional responses in different contexts. Executive functions (EF), such as cognitive flexibility, working memory, and inhibition, play a crucial role in ER development and regulation in children and adolescents. Recently, immersive virtual reality (IVR) has emerged as a novel tool for improving cognitive training interventions' accessibility and effectiveness. IVR allows users to experience immersive, three-dimensional environments, where they can interact with objects and events in a highly engaging and realistic way. Considering these developments, this study aims to explore the potential benefits of Enhance VR, a gamified IVR program designed to improve ER skills and reduce anxiety and depressive symptoms among children and adolescents. Methodology: The study will be a longitudinal, parallel, single-blind, randomized controlled pilot trial involving 80 Spanish - or English-speaking participants aged 10 to 16 years old. Participants will be excluded if they have severe psychiatric or neurodevelopmental disorders, physical, motor, or sensory impairments, or a risk of experiencing high cybersickness symptomatology during the VR experience. Participants will be randomly allocated into two groups: an experimental group receiving E-Emotio VR and a control group receiving a placebo-based VR relaxation experience. Both VR interventions will last five weeks, two times a week, for 30 minutes. The experimental group will engage in six games targeting cognitive flexibility, planning, reappraisal strategies, working memory, divided and sustained attention, and processing speed. The control group will be immersed in ten different nature-based VR environments and perform relaxation exercises. Baseline and post-intervention assessments will be conducted using age-adapted validated measures of depressive and anxiety symptoms, ER, executive function (working memory, cognitive flexibility, inhibition, and planning), and attention. Following the intervention, the assessment battery will be re-administered by a blinded assessor, and statistical analyses will be conducted for all the primary and secondary measures assessed before and after the intervention in both groups. Conclusion: In summary, this study aims to contribute to the development of effective preventive interventions for emotion regulation and mental health symptoms in children and adolescents by promoting ER through gamified VR cognitive training. The study's findings could have significant implications for mental health research, educational and clinical practice. By exploring the potential benefits of VR cognitive training, this research has the potential to inform future studies and clinical interventions aimed at improving young people's mental health and well-being. The gamification of cognitive training interventions could be a powerful tool for increasing engagement and motivation among young people, making them more likely to participate in such interventions.

This randomized, placebo-controlled clinical trial evaluates the efficacy of a polynucleotide and hyaluronic acid-based gel (PN-HA) as adjunctive therapy to non-surgical flapless treatment of peri-implantitis. The main goal is to assess probing pocket depth (PPD) reduction after 6 months compared to placebo. Study Design: * Type: Interventional (Clinical Trial) * Allocation: Randomized (computer-generated blocks) * Intervention Model: Parallel assignment * Masking: Single-blind (examiner-blinded) * Primary Purpose: Treatment * Estimated Enrollment: 32 participants * Duration: 6 month follow-up

This study aims to evaluate the effectiveness of a therapeutic exercise program designed specifically for women with breast cancer. The program includes general exercises along with specific movements for the upper limb to help reduce common side effects of cancer treatment such as lymphedema (swelling of the arm) and neuropathy (nerve pain or numbness). Participants will undergo the exercise program and be assessed before and after to determine improvements in their symptoms and overall quality of life. The goal is to provide evidence that targeted physical therapy can improve recovery and well-being in breast cancer survivors.

This study aims to evaluate the effectiveness of Capacitive Resistive Electric Transfer (CRET) therapy combined with post-competition massage in the recovery and muscle function of professional athletes. It is designed as a randomized, double-blind, crossover clinical trial. The primary objective is to analyze the efficacy of this combined protocol in muscle recovery after performing the Wingate anaerobic power and capacity test. Secondary objectives include assessing changes in muscle fatigue, muscle function of the rectus femoris and vastus lateralis, physiological changes in blood lactate concentration and oxygen saturation, and intramuscular structural changes through ultrasound before and after the intervention. The study will recruit professional athletes from disciplines that require anaerobic muscle metabolism, such as cycling, athletics, triathlon, CrossFit, and duathlon. Participants must be federated athletes who train at least four times per week and actively compete at regional, national, or international levels. Exclusion criteria include recent sports injuries preventing test performance, prior exposure to CRET therapy, allergies to conductive gel, language barriers, participation in other research studies, or ongoing pharmacological treatment that could interfere with measurements. Participants will attend four study sessions, divided into two sets of two consecutive days. On the first day, they will perform the Wingate test followed by the assigned post-competition massage with either CRET therapy or a placebo intervention. On the second day, they will repeat the Wingate test. After a three-week washout period, participants will switch to the opposite group. The intervention group will receive a 60-minute CRET therapy session with both resistive and capacitive modes applied at different power intensities, combined with a standardized recovery massage. The placebo group will receive the same massage while undergoing a simulated CRET therapy, with the machine turned on but without power application to prevent participant awareness of the placebo condition. The study will analyze various dependent variables, including Wingate test performance, blood lactate levels, subjective fatigue perception using the modified Borg scale, muscle stiffness and tone through myotonometry, muscle oxygen saturation via near-infrared spectroscopy (NIRS), cross-sectional muscle area and grayscale values from ultrasound imaging, body composition using a Tanita analyzer, maximum isometric quadriceps strength via handheld dynamometry, and muscle activity measured by surface electromyography (sEMG). Each of these variables will be assessed at specific time points before, during, and after the intervention. The estimated sample size is approximately 50 subjects, with 25 participants per group, determined through a preliminary pilot study. Statistical analyses will be conducted using IBM SPSS Statistics 26.0. Descriptive statistics will be calculated for quantitative and qualitative variables. A linear mixed model will be applied to compare changes between and within groups over five measurement periods using a one-way mixed ANOVA. If the sphericity assumption is violated, the Greenhouse-Geisser correction will be applied. Statistically significant effects will undergo post-hoc analysis with Bonferroni correction for multiple comparisons. All originally enrolled participants will be included in the final analysis following an intention-to-treat approach, and effect sizes will be calculated using eta squared. The significance level will be set at p \< 0.05.

Peri-implantitis is a plaque-associated condition occurring around dental implants, characterized by inflammation in the peri-implant mucosa and loss of supporting bone. To stop this progression, mechanical debridement of biofilm and calculus is commonly used to treat peri-implant lesions as well as the use of adjunctive measures such as titanium brushes. As observed, they improved plaque removal when compared with steel curettes alone. Therefore, it is of interest to evaluate the impact of this procedure in terms of clinical, radiographic and microbiological outcomes to assess their efficacy.

Gingival recession (GR) is a common oral health problem that causes sensitivity, esthetic concerns and hygiene problems. Successful root coverage can be achieved by various surgical techniques. The VISTA technique may overcome some of the limitations of other techniques and present equal results to techniques that are considered the "Gold Standard" in this area of periodontology. The objective of the research is to study the VISTA technique in terms of complete root coverage, % root coverage, gingival thickness gain, bleeding on probing, keratinized gingival width, PROMS, vestibular depth and esthetic results.

The purpose of the study is to compare soft tissue volume changes in terms of volume gain and stability around dental implants and PROMS in cases where a sub-epithelial connective tissue graft (SCTG) from the palate, Porcine collagen matrix (CM) or Porcine Acellular dermal matrix (PADM) is used after 3 and 15 months after implant placement.

Dental implants are worldwide recognized one of the best manners to replace lost or hopeless prognosis teeth. There are different variables that creates proper conditions for long-term prognosis of implant treatments. Implant position and surrounding bone around them, have been described in scientific literature to be key factors in the longevity of those treatments. It has to be defined the \&amp;amp;#34;critical bone thickness\&amp;amp;#34; around implants. It basically means that implants has to be completely surrounded by bone, that will serve as protection. If the implants are not surrounded by bone, procedures as guided bone regeneration may be performed. Those procedures can be executed before or simultaneously during the implant placement. In the standard procedure, the simultaneous guided bone regeneration during implant placement requires to leave the implant and the regeneration healing below the gingiva, needing a second surgery for accesing to those implants. In this randomized controlled trial the hypothesis is to discover if not submerging this regenerations may show the same results than submerged ones. For that, the objective is to study the different variables around these regeneration to evaluate the performance of non-submerged protocol.
