What indicates an increase in internal resorption in a tooth?

• A. Larger crown size
• B. Increasing root size
• C. Widening of the pulp chamber
• D. Decay on enamel

Answer: (C)

The widening of the pulp chamber is indicative of an increase in internal resorption within a tooth. Internal resorption is a pathological process in which the tooth's internal structures, particularly the pulp and surrounding dental tissue, begin to dissolve due to the activity of odontoclasts, which are cells responsible for the resorption of dental hard tissue. As this process progresses, it results in an enlargement or widening of the pulp chamber as the internal appearance of the tooth begins to change in response to this resorptive activity. This widening is an important diagnostic feature that is often assessed through radiographic imaging. It provides valuable insight into the health of the tooth and can indicate underlying issues such as trauma, chronic inflammation, or other pathological conditions that might be affecting the pulp and surrounding tissues. Recognizing this change is critical for diagnosis and treatment planning in endodontics. In contrast, larger crown size and increasing root size do not necessarily relate to internal resorption. These factors can be associated with normal tooth development or variation in morphology rather than pathological change. Similarly, decay on the enamel typically indicates caries rather than changes in the internal structure of the tooth.
