Special Issue Information

Dear Colleagues,

Pediatric dentistry is at a turning point. The next decade will determine whether the specialty evolves into a precision-based, child-centered discipline or continues to fragment under oversimplified, policy-driven models.

This Special Issue invites authors to rethink pediatric dentistry through two converging lenses:

  1. Precision & Preservation—Advancing biologically grounded, minimally invasive, and data-driven care using biomimetic materials, regenerative endodontics, salivary and microbiome biomarkers, and AI-assisted risk prediction models tailored to children.
  2. Equity & Reform—Addressing the ethical, educational, and systemic disparities that shape access, training, and quality of pediatric oral care worldwide.

We seek original research articles, reviews, and other papers that unite technological precision with social responsibility—a vision where innovation serves preservation, and preservation serves justice.

The topics of interest include, but are not limited to, the following aspects:

  • Vital pulp therapy and regenerative endodontics in immature teeth
  • Bioactive and biomimetic restorative materials in pediatric populations
  • AI and predictive analytics in risk assessment for early childhood caries and malocclusion
  • Salivary and microbiome biomarkers for personalized pediatric diagnostics
  • Digital and radiographic tools for precision-based child assessment
  • Comparative studies on pediatric dental training structures (2-year vs 3-year residencies)
  • Ethics of corporate influence and guideline formulation in pediatric dentistry
  • Global models of community-based and school-based oral health programs
  • Equity and access in pediatric oral healthcare in low- and middle-income countries
  • Integration of behavioral, psychosocial, and developmental dimensions in precision care
  • Policy, curriculum, and leadership reform in pediatric dental education

This Special Issue aims to bridge scientific innovation with moral reform, emphasizing that actual progress in pediatric dentistry depends not only on improved materials and algorithms but also on enhanced systems, practical training, and sound ethics.

By merging the scientific rigor of precision models with the global conscience of reform, this initiative aspires to set a benchmark for the "Preservation-to-Precision Era" in children's oral health.

Background/Objectives: Reliable detection of residual root canal filling material after retreatment is essential for comparing retreatment protocols. However, available methods quantify different clinical–physical dimensions and may not yield comparable estimates. This in vitro study compared cone-beam computed tomography (CBCT) and digital microscopy (DGM) for detecting residual obturation material after retreatment, using microcomputed tomography (micro-CT) as the reference standard. Methods: Fifteen extracted human mandibular premolars with single, straight canals were instrumented, obturated with gutta-percha and a calcium silicate-based sealer (AH Plus Bioceramic), and retreated with ProTaper Universal Retreatment files. Residual material was assessed in the coronal, middle, and apical thirds using CBCT (voxel size 0.10 mm), micro-CT (voxel size 60 µm), and DGM after longitudinal root splitting. Surface-based (DGM) and volumetric (CBCT and micro-CT) outcomes were analyzed separately using Wilcoxon signed-rank tests, diagnostic accuracy metrics (sensitivity, specificity, predictive values), and Cohen’s kappa for agreement. Results: DGM showed low median residual surface percentages across thirds (0.34–1.52%), whereas CBCT yielded higher median residual volume percentages (10.20–14.20%) than micro-CT (3.27–5.04%). The difference in the middle third between CBCT and micro-CT remained significant after Bonferroni correction (p = 0.002). For binary detection, CBCT showed higher sensitivity but lower specificity (overclassification of positive thirds), whereas DGM showed high specificity but limited sensitivity in the coronal and middle thirds. Conclusions: Within the limitations of this laboratory study, micro-CT was the most reliable reference method. CBCT tended to overestimate residual material, suggesting that clinical decisions based solely on CBCT may lead to unnecessary retreatment. DGM underestimated remnants because it assesses only the exposed split surface. These method-specific limitations should guide both clinical interpretation and future research design. Full article
