Which of the following is a common sensation reported by patients during an injection?

The sensation most commonly reported by patients during an injection is a feeling of burning. This sensation often arises due to several factors associated with the injection process. Primarily, it can be attributed to the acidity of the solution being injected, the speed and volume of the injection, and the specific type of anesthetic used.

When local anesthetic solutions are administered, particularly those containing preservatives or that are not at body temperature, patients may experience a burning sensation as the solution enters the tissue. This is a common and usually temporary sensation that can effectively be managed by the clinician, such as by adjusting the technique or using buffered solutions.

Understanding patient feedback related to this discomfort is crucial in ensuring a more comfortable experience during procedures that require local anesthesia. Recognizing and addressing the sensation of burning can help in enhancing patient comfort and trust in the dental care process.
