Pulpitis requires a visit to the department of stomatology or the department of dental cariology and endodontics. Some hospitals, with more detailed department divisions, differentiate between adults and children. Generally, individuals under 18 years old fall under the pediatric dentistry department. Those 18 and older need to visit the department of dental cariology and endodontics. Pulpitis is a painful condition caused by bacterial infection of the dental nerve, clinically manifested by pain when eating, night-time pain, localized pain, and worsening pain upon exposure to hot and cold stimuli. Treatment for pulpitis involves root canal therapy. This involves drilling to remove the infected dental tissue, then performing root canal medicament filling, followed by inflammation control and root canal filling.
