The systematic review evaluated the diagnostic performance of deep learning-assisted CBCT in detecting orthodontically induced root resorption (ERR). It confirmed high diagnostic accuracy and reproducibility of AI-based methods, particularly Convolutional Neural Networks (CNNs), in quantifying root volume changes and assessing ERR severity across various studies. This evidence underscores AI's potential to standardize and accelerate diagnostic processes, making it a powerful tool for early detection and objective assessment in orthodontic treatment.
The clinical case demonstrated the practical application of AI-enhanced CBCT in a high-risk scenario involving bilateral impacted maxillary canines and severe lateral incisor (LI) resorption. AI-assisted volumetric analysis provided objective evidence of progressive root damage, guiding a critical treatment modification from canine traction to LI extraction and canine substitution. This highlights AI's translational relevance in preventing irreversible damage and informing crucial, biologically safer treatment decisions in complex cases.
Key AI Performance Metric

Transformative Impact in Maxillary Canine Impaction
A 14-year-old female presented with bilateral impaction of maxillary canines (#13 and #23) and retained deciduous canines, leading to severe mesial displacement and complete overlap of canine crowns over the roots of lateral incisors (LIs) #12 and #22. Initial CBCT revealed extensive external root resorption (ERR) on the LIs, classified as Grade 3 (pulp involvement evident).
Despite attempts at distal canine traction with skeletal anchorage and auxiliary cantilevers, the canines remained unfavorably positioned. A subsequent retrospective CBCT evaluation with AI-assisted volumetric analysis was performed. This analysis confirmed significant and progressive structural deterioration: tooth #12 showed a volumetric reduction of 2.916 mm³ and tooth #22 a reduction of 2.082 mm³.
The objective AI-generated data provided critical evidence that further canine traction would be biologically unsafe. This led to a timely decision for bilateral extraction of LIs #12 and #22 and subsequent canine substitution. AI's role was decisive in recognizing biological limits, preventing further irreversible damage, and ensuring a safer modification of the treatment plan, validating its translational value in complex orthodontic decision-making.
