Dental Caries in Children

This study aims to compare salivary IL-6, MMP-8, MMP-9, and TIMP-1 levels between healthy children and caries-active children, and to evaluate the effects of 5% sodium fluoride (NaF) varnish and 2% chlorhexidine (CHX) used in caries prevention on these biomarkers. The study will be conducted at Alanya Alaaddin Keykubat University, Faculty of Dentistry, Department of Pediatric Dentistry. Informed consent will be obtained from children and their parents/guardians. Investigator calibration will be performed using Cohen's kappa method prior to data collection. Sample size was calculated assuming 80% power (1-β = 0.80), α = 0.05, and Cohen's d ≈ 0.8, resulting in 20 participants per group using G\*Power 3.1 software. Study groups: Group A: 5% NaF varnish. Group B: 2% CHX + 5% NaF varnish. Group C: Standard oral hygiene education (negative control). Group D: Caries-free children (biological reference; baseline saliva sampling only). Saliva samples will be collected at T0 (baseline), T1 (30 minutes post-application), and T2 (1 month). Unstimulated whole saliva will be collected, centrifuged at 5,000 g for 10 minutes at 4°C, and stored at -80°C. IL-6, MMP-8, MMP-9, and TIMP-1 levels will be measured using CE-marked/FDA-approved human saliva ELISA kits.

This randomized clinical trial aims to compare the clinical and radiographic performance of injectable composite versus packable composite in restoring cavitated primary molars in children aged 4 to 8 years. Study Purpose To determine whether injectable composite performs as well as packable composite in Class II restorations in primary molars clinically and radiographically.

The study aims to compare the efficacy of using bioactive cement versus resin-cement for cementation of anterior pediatric zirconia crowns.

The aim of the study is to identify adolescent patients that are at risk of developing oral diseases, and to assess if targeted preventive oral treatment with antibacterial dual-light therapy as an adjunctive treatment method can have a positive impact in preventing oral diseases from emerging.

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.

Dental caries remains a significant global public health issue, particularly affecting children's health, development, and well-being, with inadequate knowledge, attitudes, and practices around oral health exacerbating these impacts. To address this, a cluster randomized controlled trial will be conducted in four primary schools in Al Lith City, Saudi Arabia, targeting children aged 10 to 11 years. The intervention involves interactive, classroom-based educational sessions led by a dental care professional, supplemented by take-home materials, focusing first on enhancing knowledge and attitudes, and then on developing behavioral skills for improved oral hygiene and eating habits. Participants' knowledge, attitudes, and practices will be assessed via questionnaires before, immediately after, and six months post-intervention, with data analyzed using SPSS through descriptive statistics, chi-square tests, One Way-ANOVA, and Generalized Estimating Equations. The study expects that school-based oral health education will significantly improve children's oral health knowledge and certain hygiene behaviors, as well as positively influence eating habits and patterns.

There is a lack of evidence on the effectiveness of moderate sedation in pediatric dentistry, compared to protective stabilization, which remains routinely used in the Brazilian context despite moral questions. The objective of this prospective nonrandomized clinical trial is to evaluate the effectiveness of the use of moderate sedation, compared to the protective stabilization, in the dental care of children with fear / anxiety and / or dental behavior problem, and associated factors. The study will be carried out in outpatient clinics of the Dental Schools of the Federal University of Goiás (UFG) and University of São Paulo (USP), with the support of professors from King's College London through the partnership CEDACORE - Children Experiencing Dental Anxiety: Collaboration on Research and Education. Participants will be 152 children under 7 years of age with dental caries, who need specialized dental treatment due to a history of non-cooperation with dental care. The interventions to be compared are moderate sedation with oral administration of ketamine and midazolam (UFG) and protective stabilization (USP). The primary endpoint 'behavior / anxiety of the child during treatment will be assessed using the Ohio State University Behavioral Rating Scale. The secondary outcomes are: dental behavioral and anxiety evolution of the child, child' pain during procedure, impact on the quality of life related to oral health, parents and dentists' satisfaction and stress, adverse events for sedated participants, longevity of composite and glass ionomer cement restorations, chronotype and physiological stress of these children. A cost-efficacy analysis will be produced at the end of the study from the perspective of the Sistema Único de Saúde. Additionally, at the end of 36 months, the investigators expect to contribute to the identification of psychosocial aspects related to dental behavior problems in children in early childhood. It is important to highlight the perspective of technological innovation, with the creation of a digital platform that will allow the registration of data related to the dental care of children worldwide and favor analyzes in the methodology of data science.

This study proposes to conduct a randomized clinical trial (RCT), composed of a sample of 194 deciduous central and lateral incisors with active cavitated lesions, simplified ICDAS C+ score, with involvement of more than two surfaces. This sample will be divided into two experimental groups, both with selective removal of carious tissue: a group in which conventional restoration will be performed using opaque resins; and another group with monochromatic resin with chameleon effect and polyvinyl crowns.

Early Childhood Caries (ECC) is a significant clinical and public health challenge that the world and the Singapore population are facing. This study seeks to test the effectiveness of technology-enabled anticipatory guidance and peer support in empowering parents to establish proper childcare practices and prevent ECC.

The process of dental caries is dynamic and can be either reversible or irreversible depending on the balance between protective and pathologic factors in the oral cavity. Untreated dental caries causes pulpal injury, inflammation, and necrosis. Melatonin plays an essential role in the regulation of bone growth. The actions that melatonin exerts on odontoblasts may be similar to its action on osteoblasts.
