A cervical lesion should be restored if it is _____.
**Core Concept**
Restoration of a cervical lesion involves the process of filling and shaping the tooth to prevent further decay and ensure proper oral function. This procedure is crucial in maintaining the integrity of the tooth and preventing potential complications. In dentistry, the decision to restore a cervical lesion depends on various factors, including the size, location, and depth of the lesion.
**Why the Correct Answer is Right**
The American Dental Association (ADA) recommends restoring cervical lesions that are deep enough to expose the pulp or dentin, as these lesions can be painful and may lead to further complications. The restoration of cervical lesions helps to prevent the progression of the lesion, alleviate pain, and restore the tooth's function and aesthetics.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because cervical lesions that are small and superficial may not require restoration immediately, as they may be asymptomatic and not cause significant discomfort.
**Option B:** This option is incorrect because the size of the lesion alone is not a sufficient criterion for restoration, as even small lesions can be symptomatic and require treatment.
**Option C:** This option is incorrect because the location of the lesion is not the primary factor in deciding whether to restore it, as lesions in visible areas may still be asymptomatic and not require immediate restoration.
**Clinical Pearl / High-Yield Fact**
The ADA recommends restoring cervical lesions that are deep enough to expose the pulp or dentin to prevent further complications and alleviate pain.
**Correct Answer: C.
