Study Overview

Brief Summary

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)

Detailed Description

  • 58 carious lesions classified as RA2 and RA3 according to the ICDAS II criteria from three groups of 4-6 years, 6-8 years, and 8-10 years pediatric patients will be examined by near-infrared light transillumination
  • The patient acceptance towards bitewing radiograph and near-infrared light transillumination will be evulated by Simplified Facial Pain Scale (S-FPS)
  • Diagnostic performance will be assessed by calculating sensitivity, specificity, accuracy, and the area under the curve (AUC)
  • The diagnostic efficacy of the caries detection methods will be analyzed using repeated measures ANOVA, and patient acceptance will be assessed using the Chi-square test, with statistical significance set at p < 0.05 and a 95% confidence level.

Outcomes

Primary Outcomes

Age-influenced on diagnostic performance

Time Frame: From enrollment to clinical examination at day 7th

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.
