What is the diagnosis when a patient has a normal reaction to cold, no percussion sensitivity, and no X-ray findings?

In this scenario, the patient exhibits a normal reaction to cold, which indicates that the pulp is still vital and responsive. The absence of percussion sensitivity suggests that there is no inflammation or irritation affecting the surrounding structures, which often become sensitive in such conditions. Furthermore, the lack of X-ray findings indicates that there are no obvious pathological changes in the bone or tooth structure, such as resorption, lesions, or other indicators of disease.

Together, these factors strongly support a diagnosis of normal pulpal health. The pulp's normal response to cold tests, combined with the non-sensitive percussion results and clear radiographic imaging, collectively confirm that the pulp is healthy and functioning as expected. This state is characterized by the absence of any significant dental issues, such as pulp necrosis, inflammation, or infection, which would typically present with altered clinical findings.
