Summary

This study tested three methods to reduce pain and fear in 166 children aged 5-9 during dental numbing injections: a device that cools and vibrates, gentle tapping near the injection site, and a thinner needle. Researchers measured pain scores, heart rate, and cooperation. The goal is to find simple ways to make dental visits less scary for kids.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could give dentists simple, low-cost ways to make dental injections less painful and scary for children, reducing lifelong dental anxiety.
What could go wrong
This is a small, completed study with no phase designation. Results may not apply to all children or dental settings, and the methods may not work for everyone.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Children aged 5 to 9 years. Requiring dental procedures under inferior alveolar nerve block (IANB) anesthesia. Medically healthy children classified as American Society of Anesthesiologists (ASA) Class I or II. Baseline Frankl Behavior Rating of 2 or 3 (indicating cooperative or potentially cooperative behavior). Written informed consent obtained from parents or legal guardians. Age-appropriate assent obtained from the child. - Exclusion Criteria: Presence of systemic illness. Neurological disorders. Developmental conditions affecting pain perception. Previous traumatic dental injection experiences. Allergy or hypersensitivity to lidocaine with epinephrine.
