Effect of AI-Supported Child-Friendly Communication on Dental Anxiety in Pediatric Patients

This study compares the effects of traditional behavior management techniques and AI-assisted child-friendly communication on dental anxiety, physiological stress, and pain perception during local anesthesia in healthy children aged 6-12. The aim is to evaluate the effectiveness of AI-supported communication tools in reducing anxiety and improving comfort in pediatric dental treatments, potentially enhancing clinical outcomes and advancing technology use in pediatric dentistry.

Efficacy of Solventum™ Vitrebond™ Pulp Protect Liner/Base Used as a Liner/Base Under Dental Restorations

This is a clinical study evaluating a new dental product called Solventum™ Vitrebond™ Pulp Protect Liner/Base. This new product is designed to be used as a liner or base between the tooth and the dental filling, as well as for a procedure called direct pulp capping (DPC) if there is exposed pulp. Dental pulp is the part of the tooth that contains the nerves, blood vessels, and cells that keep your tooth healthy. This study will focus specifically on the liner/base application. In this study, the Solventum study product will be compared to a similar, commercially available product made by Solventum called 3M™ Vitrebond™ Plus Light Cure Glass Ionomer Liner/Base (Vitrebond Plus for short). The study will include participants who are at least 7 years old who have at least one tooth with moderate or advanced caries (tooth decay). The entire duration of the study is anticipated to be 2 years from when the first subject begins the study until the last subject completes the study. The duration of each study subject's participation will be up to 1 year consisting of an initial tooth restoration visit at baseline, a subject self-reported post-operative sensitivity assessment at 1 week reported by phone call, and in-person follow-up assessments at 1 month, 6 months, and 1 year post-restoration to confirm safety and effectiveness. The study will be partially blinded, which means that the participant and the dentist doing the assessments won't know which liner/base product is used on their tooth.

Clinical Evaluation of a New Dual-cure Universal Adhesive

The overall aim of this study is to evaluate the clinical performance and safety of the new dental dual-cure adhesive for luting indirect ceramic restorations (inlays and onlays). The primary aim is to determine the rate of postoperative hypersensitivity occurrence after using the new adhesive for the placement of indirect restorations. The secondary objective of this study is to assess the long-term clinical performance of the new adhesive in terms of marginal quality, retention/fracture rate of the ceramic restorations, and vitality/fracture rate of the restored teeth.

Comparative Study of Caries-Preventive Effects: 2% Calcium Hypophosphite Toothpaste vs. Sodium Fluoride Toothpaste (1450ppm F)

The aim of the study is to compare the caries-preventive effect of the test and control toothpaste in order to proof the non-inferiority of the test toothpaste compared to the control.

3D-printed Ceromer Crowns Versus Stainless Steel in Posterior Primary Molars

The aim of the study is to compare preformed metal crowns and 3D-printed ceromer crowns in primary molars of 4-9 years old children. The main questions it aims to answer are: * How does 3D-printed ceromer crowns compare clincally to stainless steel crowns when restoring posterior molars? * What is the level of satisfaction of the patient with both materials? * What is the level of parental satisfaction with both materials? Study methodology: This study is a split-mouth clinical trial where participants will receive at least one of each materials in different quadrants of the mouth.

Orthodontic Treatment on Oral Microbiota and Salivary Proteins

Study on the changes in oral microbiota during orthodontic treatment in patients aged 8-18 years. Orthodontic patients treated at Stomatology Hospital of Xi'an Jiaotong University from March 2025 to March 2027 will be recruited. Prior to orthodontic treatment, routine preoperative examinations will be conducted, informed consent forms will be signed, baseline oral conditions will be recorded, and oral and psychological-related questionnaires will be completed. Patients will be informed of the need for regular oral hygiene check-ups, caries risk assessments will be performed, and plaque, saliva, and intraoral photographs will be collected. During orthodontic treatment, plaque samples will be collected every 3 months, and saliva samples will be collected every 6 months until the treatment is completed to evaluate the changes in oral microbiota throughout the orthodontic process.

Performance of Bioactive Low Viscosity Composite in Deep Marginal Elevation Restorations

The goal of this study is to evaluate the clinical, radiographic and periodontal performance of bioactive Giomer Shofu Flow Plus X F03 compared to nanohybrid resin composite restoration in deep subgingival proximal cavities over a period of 12 months.

Effect of Caries Conceptualizing and Residential University Life

The study aims to detect the conceptualization of dental caries among dental student and compare the caries prevalence in residential and non residential dental student

Partial Caries Removal in Permanent Molars Restored Using Giomer

Dental manufacturers\' constant tweaks and improvements to composite compositions have resulted in a wider spectrum of restorative materials with positive long-term clinical performance. For example, the creation of bioactive giomer material with proven continuous multi-ion release has been beneficial in avoiding demineralization and imparting acid resistance to enamel and dentin.
