Which type of thermometer is typically used for oral temperature readings?

A digital thermometer is typically used for oral temperature readings due to its ease of use, accuracy, and quick response time. Digital thermometers provide a clear digital display, which allows for straightforward reading of the temperature. They are designed to be safe and hygienic, making them suitable for oral use, as they can be easily cleaned and are less fragile than glass mercury thermometers.

While glass mercury thermometers can also provide oral readings, they are less common today due to safety concerns regarding mercury and the potential for breakage. Infrared thermometers, primarily used for measuring temperature without direct contact with the body surface, are generally employed for forehead readings rather than oral use. Rectal thermometers are specifically designed for rectal use and are known for providing accurate temperature readings, particularly in infants or patients who are unable to use oral thermometers. However, they are not suitable for oral readings.
