NCT06183320
Treatment clinical trial, randomized, controlled, parallel, double-blinded, with two groups, that aims to evaluate the best application strategy when using a flowable bulk fill composite (Opus Bulk Fill Flow APS, FGM, Brazil) in class II cavities. Volunteers will be selected and recruited, following inclusion criteria and pre-established exclusion criteria. All volunteers will be informed and sign a term of clarification and consent. 38 enrolled patients will receive 76 Class II dental restorations, made in two different ways, one from each experimental group. Authors will perform restorations with an incremental composite (Vittra APS - FGM) associated with a bulk-fill flowable composite (Opus Bulk Fill Flow APS - FGM), in class II cavities, exposing (Group BP) or not (Group IP) the bulk fill flowable composite to the cavosurface angle on the proximal wall of the restorations. In both groups, Opus Bulk Fill Flow APS resin will be used in the bulk technique with up to 5mm depth increments, leaving 1 mm in the occlusal for incremental Vittra APS composite resin. Immediate post-operative tooth sensitivity will be evaluated after one week. Restorations will be evaluated every 6 months for pain assessment, shape, fractures, staining or recurrent caries, using FDI scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.
NCT03343184
Treatment clinical trial, randomized, controled, parallel, double-blinded, with four groups, that aims to evaluate the best application strategy when using a Universal Adhesive system, Single Bond Universal (3M ESPE, USA), in self-etch application mode, with or without enamel etching, associated wity a Bulk Fill Composite (Filtek Bulk Fill, 3M ESPE, USA), or with a conventional nanofilled composite (Filtek Z350 XT, 3M ESPE). Volunteers will be selected and recruited,following inclusion criteria and pre-established exclusion. All volunteers will be informed and sign a term of clarification and consent. 50 enrolled patients will receive 200 Class I or Class II dental restorations, made in four different ways, one from each experimental group, using the same universal self-etching adhesive system, with two application strategies, under the restorations that will use two different composites, a bulk fill composite, used in the bulk strategy, or a nanofilled composite, used in the traditional incremental strategy. Occlusal or Proximo-occlusal lesions will receive the selected adhesive system in 2 different protocols separated by groups. Group Self Etching and Bulk Fill (SETB), Group Selective enamel etching and Bulk Fill (SEEB), Group Self Etching and Filtek Z350XT (SETI), and Group Selective enamel etching and Filtek Z350XT (SEEI).Total time used in the restorations will be evaluated during the restorations. Immediate post-operative tooth sensitivity will be evaluated after one week. Restorations will be evaluated every 6 months for pain assessment, shape, fractures, staining or recurrent caries, using scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.
NCT07581938
This is a prospective, cross-sectional observational study designed to evaluate the Pediatric Sleep Questionnaire (PSQ) as a screening tool for sleep-disordered breathing (SDB) risk in a pediatric dental setting. Children aged 8-13 years will be classified as low- or high-risk for SDB based on PSQ scores and compared using physiologic sleep parameters obtained from a wearable, FDA-cleared home sleep monitoring device, alongside psychosocial assessments and craniofacial measurements derived from lateral cephalometric radiographs. Findings will inform the feasibility and accuracy of incorporating validated SDB screening into routine pediatric dental care.
NCT07348770
Cold plasma-mediated implant surface activation may reverse the biological aging of titanium by enhancing hydrophilicity and cellular response. The aim of this study was to clinically compare the effects of three different cold plasma systems on the stability of dental implants. In this prospective randomized controlled within-patient trial, a total of 44 implants were placed in 11 patients. In each patient, four implants were randomly allocated to one of the following groups: control, vacuum plasma, argon jet plasma, and cold atmospheric plasma. All implants were placed using a single-stage protocol with a minimum insertion torque of 45 Ncm. Implant stability was assessed using resonance frequency analysis (ISQ values) immediately after placement and at 2, 4, and 8 weeks.
NCT06647381
The population of interest will be recruited out of a cohort of patients who were initially treated at the Department of Oral Surgery and Stomatology between 1997 and 2001. The findings from a total of 56 patients that received tooth replacement treatment with dental implants during this period, were previously published in 2008. Now, 20 years later, the investigators will potentially recruit and re-examine as many patients as possible out of this original cohort. Exclusion criteria will be patients not able to come to the re-examination, concomitant diseases that compromise the health of this subject during the comprehensive examination (i.e., active severe infectious diseases, liver or kidney dysfunction/failure, currently under treatment), pregnant women, or unwilling to sign the consent form. Besides them, no further exclusion criteria are defined as patients receiving no intervention. The investigators assume that will be able to retrieve 40 patients having roughly 80 implants with sinus floor augmentation. Recruitment, screening, and informed consent procedure Patients treated at the Department of Oral Surgery between 1997 and 2001 and who were included in the previous case series study will be potentially recruited. Patients who are willing to participate will receive informed consent. The risks and benefits of being part of this study will be thoroughly explained to the patients without a limit of time. All the questions will be answered. After signing the informed consent patients will be examined. The participants will not be charged any costs for the recall examination. Study procedures After ethical approval, available patients will be screened and recruited for a re-examination visit. The anamnesis of the patients will be assessed using a questionnaire. In case of uncertainties regarding the medical history, a report from the patient's physician will be requested. During this re-examination, photographs, in combination with a comprehensive and standard clinical and digital examination will be taken. Further, patients will be given questionnaires to assess patient-reported outcomes. The evaluation visit will take place within a maximum of 1 hour, as the normal time required for a recall appointment on this type of patient with the presence of dental implants. Besides this one re-examination, no more visits will be necessary for the study outcomes. Data will be encrypted and collected in Redcap Software. The key for the encryption will be set up and stored by a person who is not involved in the study.
NCT04945993
The aim of root canal treatment, or endodontic treatment, is to treat pulpal or periapical diseases and thus transform a pathological tooth into a healthy, asymptomatic and functional entity on the dental arch. The diagnosis of pulp pathology is based on the symptomatology described by the patient, on data from the clinical examination and tests performed as well as the radiographic examinations. Different families of root canal sealers are used in endodontics: cements based on zinc oxide-eugenol (ZOE), resin-based materials, and calcium silicate-based cements. They provide a stable and hermetic sealing. The Septodont laboratory has developed and manufactured endomethasone N, a zinc oxide-eugenol root canal sealer. The aim of this retro-prospective PMCF study is to collect long term clinical and safety data on root canal obturation after treatment or retreatment by Endomethasone N.
NCT07555223
This prospective clinical study aims to evaluate the diagnostic accuracy of intraoral scans (IOS) for the detection of dental plaque and caries. The diagnostic performance of IOS will be compared with current clinical reference standards. For plaque assessment, IOS-based evaluation will be compared with plaque detection using disclosing agents. For caries detection, IOS (including white-light imaging and caries detection features) will be compared with conventional visual inspection and bitewing radiography. Adult patients aged 18 to 70 years will be included.
NCT04732533
In this project, the investigators propose to demonstrate the feasibility of remotely-monitored, caregiver (or spouse)-administered, home-based tES (transcranial electrical stimulation) intervention to improve mobility in ambulatory older adults with recent falls. This is a four-phase feasibility study in older, ambulatory adult participants at risk of falling due to a loss of balance (participant faller, PF) together with a willing and able participant administrator (PA) that is available during weekdays to administer tES to the PF. Phase 1 is focused on the development and refinement of our training materials for home-based tDCS (transcranial direct current stimulation) for PF/PA pairs. The objectives of this phase: 1. Identify areas of confusion and challenges for older adults. 2. Refine our training materials to accompany the home-based tDCS system. In Phase 2, the investigators will complete a pilot trial in 12 PF/PA pairs to assess the feasibility of deploying home-based tES in larger clinical trials, and to prepare for the development and implementation of such trials. The objectives of this phase: 1. Determine the mean/range number of visits needed for in-person training. 2. Compliance and retention with the study protocol. 3. Safety/side effects of home-based tES, as compared to previously established laboratory-based tES data. The investigators hypothesize that adult PAs are able to successfully administer home-based tES to PFs. The investigators also expect that PF/PA pairs will exhibit excellent adherence to the intervention and that the prevalence and severity of reported tDCS side-effects will be similar to that observed in previous laboratory-based studies. In Phase 3, the investigators will complete a pilot trial in up to 18 PF/PA pairs; i.e., those who have previously successfully completed either Phase 1 or Phase 2. The study objectives/aims for Phase 3 are: 1. Further explore compliance and retention with the study protocol over a longer time period 2. Identify safety/side effects of home-based tES over a longer time-period as compared to previously established laboratory-based tDCS interventions. In Phase 3, the investigators hypothesize that adult PA's who have previously demonstrated the ability to successfully administer tES at home, will retain competence and compliance with administration over a longer period, up to 1 year. In Phase 4, we will complete a pilot trial in up to 18 PF/PA teams; those who have previously successfully completed Phase 3. The study objective/aims for Phase 4 will be to: 1. Identify Safety, effectiveness and adherence to home-based tES over longer period of time as compared to previously established laboratory-based tES interventions. 2. Further explore the proof of Concept for the home-based tES interventions In Phase 4 we hypothesize that adult PA's who have previously demonstrated the ability to successfully administer tES at home, will adhere with the study protocol over a longer period of time, up to 3 years.
NCT07546773
Achieving effective root canal disinfection while minimizing postoperative pain is a critical goal in endodontic therapy. Advanced irrigation protocols, such as ultrasonic activation, laser activation, negative pressure irrigation (PulpSucker device), and mechanical activation (Easy Clean device), have shown promise in enhancing bacterial reduction within the root canal system. However, their impact on postoperative pain has not been fully explored. This randomized controlled clinical trial aims to compare bacterial reduction and postoperative pain levels in infected root canals using four different irrigation protocols. The study will use metagenomic analysis to evaluate changes in bacterial community composition and the Visual Analogue Scale (VAS) to assess patient-reported pain levels at multiple time points postoperatively.
NCT07346391
This clinical trial aims to evaluate the clinical effectiveness of combining a strip free gingival graft (sFGG) with Platelet-Rich Fibrin (PRF) for increasing keratinized mucosa around dental implants. The study compares this combined technique with the conventional free gingival graft (FGG) method through three primary objectives: 1. comparing the increase in keratinized mucosal height at immediate post-op, 1, 3, and 6 months; 2. assessing post-operative pain levels at 1, 3, 7, and 14 days; 3. evaluating soft tissue aesthetic outcomes at 4 and 6 months post-surgery.
NCT05816525
The goal of this prospective, observational clinical cohort study is to study the effect of the preoperative condition of the tooth on the outcome of partial removal of carious tissue in mature teeth in adults. The main questions the study aims to answer are: * Do preoperative symptoms affect the outcome? * Does the depth of the carious lesion affect the outcome? One hundred participants will be recruited. Patients who meet the eligibility criteria will be asked to give their informed consent to participate in the study. Partial carious tissue removal will be performed regardless of participation in the study because selective carious tissue removal is the standard treatment of choice for a vital tooth with a deep carious lesion according to the Finnish national treatment guidelines. Participants will be asked to fill in a questionnaire regarding symptoms 7 days post-treatment. The teeth will then be followed up for 12-24 months. The null hypothesis is that there is no difference in the success between i) deep and extremely deep carious lesions and ii) initial and mild pulpitis.
NCT07539181
This randomized controlled clinical trial aims to evaluate the effectiveness of plaque disclosing agents used as photosensitizers in antimicrobial photodynamic therapy (aPDT) for the control of dental biofilm in children aged 3 to 7 years. Participants will be allocated into groups to receive different treatment protocols, and biofilm levels will be assessed before and after the interventions. The primary outcome is the reduction of dental biofilm, aiming to determine whether disclosing agents can be an effective alternative photosensitizer in aPDT for pediatric patients.
NCT06581250
The goal of this study is to compare different no-show interventions in dental clinics serving underserved populations. The main question it seeks to answer is * How do different no-show intervention methods compare in reducing no-shows? Participants will be asked to * Implement different interventions * Report a limited set of data to researchers

Radiographic evaluation of the bone density and tissue thickness will be performed by CBCT preoperatively, immediate postoperative and after the procedure by 4 months. Clinical evaluation of the tissue thickness using periodontal probe preoperatively, immediate postoperatively and after the procedure by 4 months
NCT07480239
This cross-sectional study aims to evaluate how interdental spacing and crown width discrepancies in primary dentition influence the perception of smile esthetics. Standardized smile photographs obtained from children with physiologic spacing patterns will be digitally modified to create different dental scenarios, including variations in interdental spacing, midline deviation, and crown width discrepancies. The images will be presented to adult participants, including dental students and parents, who will evaluate the esthetic appearance of each smile using a visual analog scale (VAS). The study seeks to determine how different spacing patterns and tooth size discrepancies affect the perception of smile esthetics in primary dentition.
NCT07484334
This study evaluates whether physician-guided visual information provided before impacted mandibular third molar surgery can improve hemodynamic stability during the perioperative period. Participants are assigned to one of three preoperative information methods: standard verbal information, real surgical video information, or 3D animation video information. Changes in systolic blood pressure, diastolic blood pressure, heart rate, and oxygen saturation are assessed at multiple perioperative time points to determine whether visual information reduces stress-related physiologic responses. The study also examines whether these information methods influence preoperative dental fear.
NCT07509320
This systematic review aimed to synthesize current evidence regarding the prevalence, anatomical distribution, etiological determinants, and diagnostic assessment of permanent canine impaction. A comprehensive literature search was conducted in PubMed, PubMed Central, and ScienceDirect for studies published between December 2009 and December 2025. Study selection followed PRISMA 2020 guidelines. Two independent reviewers screened titles, abstracts, and full texts, and methodological quality was assessed using the Joanna Briggs Institute critical appraisal tools. Thirty-one studies met the inclusion criteria and were included in the qualitative synthesis. Reported prevalence of maxillary canine impaction ranged from approximately 0.97% to 7.10%, with mandibular impaction occurring less frequently. Palatal displacement represented the most common positional pattern. Major etiological factors included retained deciduous canines, dental arch constriction, supernumerary teeth, odontomas, and genetic anomalies. Cone-Beam Computed Tomography demonstrated superior diagnostic accuracy compared with conventional radiographic methods. The review provides a comprehensive synthesis of epidemiological patterns, etiological mechanisms, and imaging considerations associated with permanent canine impaction, highlighting the importance of early diagnosis and appropriate radiographic assessment.
NCT07507136
Cements on the base of the calcium silicates, like Mineral trioxide aggregate (MTA), and our cement mixture ALBO MPCA, as the object of this clinical trial, have various clinical applications. In the field of dentistry, they can be used in many ways during endodontic treatment procedures of both primary and permanent teeth. The high prevalence and recurrent nature of dental caries and periodontal disease demand endodontic treatment procedures. According to the World Health Organization (WHO), the Global Burden of Disease Study 2017 reported that untreated dental caries in permanent teeth is the most common health condition among the population. It has also been reported that 2.3 billion adults suffer from dental caries of permanent teeth, and over 530 million children suffer from dental caries of primary teeth (milk teeth) across the globe. Thus, the growing prevalence of tooth decay and gum diseases is likely to favor the growth of the market during the next period. The overall prevalence of caries increases with age, and the incidence rises steeply in adults older than 30-40 years. Such a burden of caries will continue to increase with the growing ageing population. The Global Burden of Disease Study in 2016 estimated that oral diseases affected half of the world's population (3.58 billion people), with dental caries in permanent teeth being the most prevalent condition assessed, while in children aged this number accounts for about 486 million. Early identification of children who are at high risk for dental caries indicates the need for a Caries-Risk Assessment (CRA) tool. Early CRA literature confirms the value of the identification of caries as a reliable way to predict future caries. On the basis of World Health Organization (WHO) data for decayed, missing, and filled teeth (DMFT), dental decay is the most prevalent chronic disease, and it is correlated to the consumption of carbohydrates and enamel demineralization due to microorganisms. More than 90% of people suffer from this disease. WHO reported that 60% to 90% of schoolchildren all around the world suffer from dental decay, and it is more prevalent in Asian countries and Latin America. In some reports in Bosnia and Herzegovina, almost all of the examined children had caries. The DMFT index shows that the number of diseased teeth is more than 4, even in the teenage years. In Serbia, only 8.5% of the population has all healthy teeth, while 9.3% of the population is toothless. Total income related to the caries healing is about 100 Euros per inhabitant, assuming that dental health control is regular, and if only one intervention on the teeth is made during one year. This is an enormous amount of money, showing the huge economic importance of the topic. Economical estimation for Bosnia and Hercegovina show income order of several tens of millions KM, therefore, successful treatment of caries has huge importance from the financial aspect also. In Serbia is a similar situation. The application of the ALBO-MPCA in various endodontic indications is considered the essential method for significant improvement of oral health for patients with advanced periodontitis. Following the main requirements for an ideal dental cement, such as its fast setting, pretty high compressive strength, satisfactory chemistry, antimicrobial properties, and particularly high biocompatibility and non-toxicity ALBO-MPCA shows the significant advantages compared with recently used dental calcium silicate cements, particularly expressed in its extraordinary high depth of the reparative dentin bridge, approved in a wide scale of animal assays. Therefore, it will be applied in clinical trials, for the healing of the tooth canal, direct pulp capping, and other endodontic applications, typical for such kinds of medical devices. Financial support of the study is provided by the sponsor's consortium, with ALBOS as the sponsor. The recruitment site is the House Health, Foča in the Republic of Srpska, Bosnia and Herzegovina.
NCT07452614
This prospective controlled clinical trial investigates whether metabolic biomarkers measured in pulpal blood at the time of carious pulp exposure can predict the 12-month outcomes of vital pulp treatment in symptomatic permanent teeth. Eligible patients aged 16-50 years presenting with deep carious pulp exposure will undergo vital pulp therapy (partial pulpotomy or full pulpotomy). Pulpal blood samples will be collected at the time of exposure and analyzed using High-Performance Liquid Chromatography (HPLC). Treatment outcomes will be assessed clinically and radiographically at 12 months. The study aims to identify objective, measurable biomarkers that can improve pulpal diagnosis and guide clinical decision-making in vital pulp therapy.
NCT07209696
This study is designed to evaluate strategies for reducing dental anxiety in pediatric patients. The commonly applied "Tell-Show-Do" method involves explaining and demonstrating dental procedures before they are performed. In this randomized controlled trial, three groups of children will be compared: Children who receive only the Tell-Show-Do method, Children who are prepared at home with a storybook prior to receiving the Tell-Show-Do method, Children who are prepared at home with an animation video prior to receiving the Tell-Show-Do method. Children's dental anxiety will be assessed using validated behavioral observation scales, including baseline measurement at the first examination, after preparation, and following completion of dental treatment. The study will determine whether the addition of a storybook or an animation video provides greater effectiveness in reducing dental anxiety compared with the Tell-Show-Do method alone.
