Which of the following signs could indicate reflux esophagitis?

Tooth erosion and persistent coughing are indeed indicative of reflux esophagitis. Reflux esophagitis occurs when stomach acid flows back into the esophagus, leading to inflammation and irritation. This condition can affect dental health, as the acid can erode tooth enamel, leading to tooth erosion. The persistent coughing can occur as a reflex reaction due to the acid irritating the throat and esophagus, which may cause a sensation of difficulty swallowing or trigger a cough to clear the airway.

In contrast, signs such as rashes and skin irritations are more commonly associated with allergic reactions or dermatological conditions rather than reflux esophagitis. Similarly, chest pain and shortness of breath might suggest other underlying conditions such as cardiac issues or respiratory problems rather than directly indicating reflux. Headaches and dizziness generally relate more to neurologic or systemic issues and do not specifically point to esophageal reflux. Each of these other signs might suggest different health concerns that require distinct evaluations and interventions.
