Why must a digital sensor be protected from liquids?

A digital sensor must be protected from liquids primarily to avoid damage to the expensive equipment. Digital sensors contain sensitive electronic components that can be severely affected by moisture or any liquid intrusion. Exposure to liquids can lead to short circuits, corrosion, and eventual malfunction of the device, resulting in costly repairs or the need for replacement.

Protecting these sensors is crucial for maintaining functionality and ensuring the quality of dental imaging, as well as for safeguarding the investment in this critical technology. The question emphasizes the importance of proper handling and care of digital sensors in dental practice to ensure their longevity and reliability. Other factors, such as the sensor's weight or the ability to sterilize it, do not address the primary concern of preserving its operational integrity.
