NCT07515612

Brief Summary

This randomized controlled clinical trial aims to evaluate and compare the effectiveness of chamomile extract and valerian extract in reducing dental anxiety in healthy pediatric patients aged 6 to 10 years undergoing tooth extraction. Participants will be randomly assigned to receive one of the herbal interventions or a placebo prior to extraction. Dental anxiety will be assessed using validated anxiety rating scales and physiological parameters. This study seeks to explore a safe, easy to apply, and effective approach to manage child behavior and reduce dental anxiety.

Outcome Measures

Primary Outcomes (2)

  • Self-reported dental anxiety level

    Dental anxiety will be assessed using the Animated Emoji Scale (AES); a scale that consists of five facial expressions (emojis) scored from 1 (no anxiety) to 5 (high anxiety).

    Before the herbal extract administration - after 30 minutes from ingestion - after 5 minutes from local anesthesia - immediately after extraction.

  • Non-self-reported dental anxiety level

    Dental anxiety will be assessed using the Houpt Behavior Rating Scale, by an independent external observer based on video recordings.

    Throughout the dental procedure: 1. during local anesthesia (from needle insertion until needle withdrawal) 2. during extraction (from the initial application of forceps until complete tooth removal)

Secondary Outcomes (2)

  • Physiological response to dental anxiety - Heart rate

    Before herbal extract administration - after 30 minutes from ingestion - after 5 minutes from local anesthesia

  • Physiological response to dental anxiety - Blood pressure

    Before herbal extract administration - after 30 minutes from ingestion - after 5 minutes from local anesthesia
