Abstract

Dental cone-beam computed tomography (CBCT) provides volumetric evidence for diagnosis and treatment planning, but construct- ing a structured report from a full volume remains challenging because clinically relevant findings are distributed across numerous slices and must be consistently linked to patient-specific tooth positions, diagnoses, and treatment actions. This challenge is amplified under limited paired supervision, where unrestricted text generation is prone to memorizing training reports or producing unsupported clinical content. To address these challenges, we propose DentSAFER, a dental self-supervised action- aware field retrieval framework with entity refinement. DentSAFER first pretrains a compact 3D encoder using variance-invariance-covariance reg- ularization and then jointly learns representations for seven report fields together with predictions for 32 FDI tooth positions and 21 treatment actions. At inference, the seven report fields are constructed through constrained retrieval from the labeled report library rather than unre- stricted decoding. During retrieval, the diagnosis and treatment plan are selected jointly using action compatibility, while patient-specific tooth codes are removed from the retrieved text and replaced with tooth codes derived from image-conditioned predictions before final report assembly. On the official test set, DentSAFER achieved a Weighted Score of 0.2193, demonstrating the feasibility of structured dental report construction under limited paired supervision.
