Defining characteristics: The presence of an area or multiple areas of decay/degradation has been identified within a tooth/teeth, likely secondary to a resorptive process. Resorption often appears as irregular radiolucencies throughout the tooth.
Common differential diagnoses: Radiolucent lesions in teeth are often attributed to primary resorptive lesions, trauma, neoplasia, inflammation/infection, caries (cavity), and enamel hypoplasia.
Helpful additional data: Has there been a decrease in appetite? Or the patient appears hungry but is unwilling to eat?
