Development and Internal Evaluation of an Interpretable AI-Based Composite Score for Psychosocial and Behavioral Screening in Dental Clinics Using a Mamdani Fuzzy Inference System
The study developed an interpretable AI-based composite score for psychosocial/behavioral screening in dental clinics, integrating GAD-7, PHQ-9, and OBC-21 using a Mamdani fuzzy inference system (FIS). The score, called PCS, ranges from 0-10 and aims to provide a single, auditable output for stratification and documentation, demonstrating internal coherence and robustness against measurement noise.
Executive Impact & Key Metrics
This AI system streamlines complex multidomain psychosocial screening in dental clinics, offering a unified, interpretable score that enhances workflow efficiency and patient stratification. By reducing the need for multiple separate scores, it simplifies communication and documentation, directly impacting patient care and operational costs.

Fuzzy Logic Model
The Mamdani-type fuzzy inference system (FIS) integrates GAD-7, PHQ-9, and OBC-21 scores into a 0–10 psychobehavioral composite score (PCS). It uses triangular membership functions and 48 predefined IF–THEN rules, without supervised training, ensuring full interpretability and auditable logic. Centroid defuzzification yields a crisp output.
Internal Evaluation Metrics
PCS demonstrated strong positive correlations with all input measures (Spearman ρ: 0.886 for GAD-7, 0.792 for PHQ-9, 0.687 for OBC-21), increasing monotonically across severity strata. Robustness was excellent under input perturbations (ICC(3,1) > 0.983) and high for membership function variations (ICC(3,1) = 0.959). Concordance with linear baselines was high (Spearman ρ ≈ 0.956).
Clinical Utility & Limitations
The PCS is intended for non-diagnostic, screening-oriented stratification and standardized documentation. It does not replace clinical assessment. Limitations include its cross-sectional design, reliance on self-report, and the need for external clinical validation against independent outcomes to claim diagnostic or predictive utility.

Psychobehavioral Composite Score (PCS 0-10)
0
The median PCS indicates a generally low severity level in the study population, reflecting the distribution of input scores.
The median psychobehavioral composite score (PCS) in the study population was 2.30 (IQR 2.03–3.56). This value, on a 0–10 scale, reflects the overall psychobehavioral vulnerability, with higher scores indicating greater severity. This initial baseline indicates the typical patient profile encountered in participating dental clinics.

Case Study: Implementing PCS for Enhanced Dental Patient Management
Summary: A large dental network sought to standardize psychosocial screening across its multiple clinics to improve patient care pathways and reduce variability in clinical responses to anxiety, depression, and oral behaviors.
Challenge: Prior to PCS, clinicians used separate GAD-7, PHQ-9, and OBC-21 scores. This led to fragmented interpretations, inconsistent documentation, and varied referral decisions, making it difficult to identify patients needing tailored communication or specialized support efficiently.
Solution: The dental network adopted the interpretable AI-based PCS. This system integrated the three self-report measures into a single, continuous 0–10 score, providing a unified indicator of psychobehavioral vulnerability. Training focused on interpreting PCS levels for adaptive communication, pacing, and referral signposting, without replacing diagnostic assessment.
Results: Initial implementation showed a significant increase in standardized documentation and more consistent patient stratification. Clinicians reported improved ease of communication regarding patient psychosocial profiles. The auditable nature of the FIS allowed for transparent review of the integration logic, fostering trust and facilitating local refinements. This led to more proactive management of patient needs and a more cohesive care approach across the network.

Implementation Timeline
Our roadmap outlines a phased approach for integrating the Interpretable AI-Based Composite Score into your dental practice, ensuring smooth adoption and maximized benefits.
Phase 1: System Integration & Training
Integrate the PCS calculator into your existing patient management system and conduct comprehensive training for dental staff on interpreting and applying the PCS for patient stratification and documentation.
Phase 2: Pilot Program & Feedback
Implement the PCS in a pilot group of clinics. Collect feedback from clinicians and patients, and conduct an internal audit of initial outcomes and workflow adjustments.
Phase 3: External Validation & Refinement
Initiate prospective external validation studies against clinically meaningful outcomes (e.g., treatment adherence, patient satisfaction) to confirm predictive utility and refine the PCS mapping based on real-world data.
Phase 4: Full Network Rollout & Ongoing Support
Roll out the PCS across your entire dental network, establish ongoing support channels, and monitor long-term impact on patient care, operational efficiency, and clinical decision-making.
