In a deep proximal caries near the pulp in a mature tooth, how do you decide among indirect pulp therapy, direct pulp capping, pulpotomy, or full-coverage restoration?

• A. Only the color of the tooth.
• B. Predictable to choose pulpotomy in all cases.
• C. Assess pulp vitality, caries depth, symptoms, and tooth strategic importance; reversible pulpitis supports protective caries control; necrotic pulp requires RCT; extensive structure loss may require full-coverage restoration.
• D. Always perform full-coverage restoration.

Answer: (C)

The main idea is to tailor the plan to the pulp status, how deep the caries is, the patient’s symptoms, and how important that tooth is for function. When the pulp is still vital and the caries hasn’t exposed it, indirect pulp therapy lets you seal off the deepest carious dentin and promote remineralization, reducing the risk of exposure and future pulp problems. If there is an exposure but the pulp responds well and symptoms point to reversible inflammation, direct pulp capping can be used to encourage a dentin bridge and maintain pulp vitality, though its success depends on careful technique and case selection.

If inflammation is limited to the coronal pulp and keeping the radicular pulp alive is desirable, a pulpotomy may be considered, especially in teeth where maintaining vitality supports long-term success. When the pulp is necrotic or there are signs of irreversible pulpitis, root canal therapy becomes the appropriate course to remove infection and preserve the tooth.

Finally, if there has been extensive loss of tooth structure or the tooth’s role in the bite requires maximum protection, a full-coverage restoration (such as a crown) helps restore form and function and shield remaining tooth structure.

In short, the right choice comes from assessing pulp vitality, how deep the caries is, the patient’s symptoms, and how strategically important the tooth is. This approach accounts for protective caries control when possible, escalation to definitive pulp therapy if needed, and restoration options to preserve tooth integrity.
