Risk Factors on the Long-Term Success of Mineral Trioxide Aggregate Pulpotomy

The goal of this observational study is to learn about the long-term results of Mineral Trioxide Aggregate (MTA) pulpotomy in primary molars and the factors that may affect treatment success. The main question it aims to answer is: Do clinical, operator and restoration-related factors influence the long-term success of MTA pulpotomy in primary molars? In this study, children who received MTA pulpotomy treatment were examined at the 24-month follow-up visit, scheduled at the beginning of the study. Two examiners checked the clinical condition of the teeth, and two other examiners reviewed the radiographs without knowing the clinical results.

Diagnostic Performance and Children's Acceptance of Near-Infrared Light Transillumination and Bitewing Radiographs for Detecting Proximal Cavitation in Primary Molars of Patients Aged 4 to 10 Years

The goal of this observational study is to compare the diagnostic performance of three detection methods for approximal carious lesions in primary molars among pediatric patients aged 4-10 years. The study focuses on children in three age groups: 4-6 years, 6-8 years, and 8-10 years. The main questions it aims to answer are: * Are the sensitivity, specificity, accuracy, and area under the curve (AUC) different across the three diagnostic techniques (bitewing radiography, near-infrared light transillumination, and their combination)? * Are these diagnostic parameters influenced by patient age? * Which technique yields the highest level of patient acceptance? Researchers will compare the three diagnostic approaches to determine whether age influences diagnostic performance and patient acceptance. Participants will: * Be examined using bitewing radiography and near-infrared light transillumination * Undergo tooth separation for 7 days using orthodontic elastic separators * Receive clinical examination of the target approximal surface * Be asked to rate their experience using the Simplified Facial Pain Scale (S-FPS)
