About this trial
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)

Trial outcomes
Primary outcomes
Diagnosis performance
The diagnostic performance will be described by sensitivity, specificity, accuracy, and the Area Under the Curve (AUC), with values ranging from 0 to 1 for each parameter. * For sensitivity, zero is equivalent to no true positives detected, and 1 indicates all true positives detected * For specificity, zero is equivalent to no true negatives detected, and 1 indicates all true negatives detected * For accuracy, zero is equivalent to all cases misclassified, and 1 indicates all cases correctly classified * For AUC, zero is equivalent to a perfectly incorrect classification, and 1 indicates a perfectly correct classification
Age-influenced on diagnostic performance
The diagnostic performance for each age group will be described by sensitivity, specificity, accuracy, and the Area Under the Curve (AUC), with values ranging from 0 to 1 for each parameter. * For sensitivity, zero is equivalent to no true positives detected, and 1 indicates all true positives detected. * For specificity, zero is equivalent to no true negatives detected, and 1 indicates all true negatives detected. * For accuracy, zero is equivalent to all cases misclassified, and 1 indicates all cases correctly classified. * For AUC, zero is equivalent to a perfectly incorrect classification, and 1 indicates a perfectly correct classification.
Secondary outcomes
Children's acceptance
Children's acceptance will be evaluated using the Simplified Facial Pain Scale (S-FPS), which ranges from 0 to 10. The minimum value is 0, representing "no pain", and the maximum value is 10, representing "severe pain".
