Heat maps for all six diseases and each disease. Heat maps depicting the prevalence of six oral diseases (caries, pulp exposure, periradicular lesions, impacted teeth, residual roots, and missing teeth) across tooth positions. Each map uses a gradient color scale where deeper red shades indicate higher prevalence. These maps emphasize disease hotspots, such as the mandibular first molars for caries and residual roots, highlighting their clinical importance for preventive care.
