Background:
Anxiety is an important problem in children in dental clinics. Acupressure may be a useful tool to assist in dental procedures in anxious children.
Objectives:
This pilot study was performed to examine the effects of acupressure on dental anxiety in children undergoing restorative procedures.
Methods:
Fourteen children aged 7-10 years and with at least one primary molar with caries on the dentine were included in the study. The participants also needed to score at least one point on the modified Venham Picture Test (VPTm) for the determination of anxiety. The children were randomly allocated to two groups: group A - non-documented points for the reduction of anxiety and induction of relaxation; group B - documented points (EX-HN3, Shen Men of auricular acupuncture). The anxiety scale was administered on three occasions: prior to the application of acupressure; immediately after sitting in the dental chair to undergo restorative treatment; and after removal of acupressure at the end of the restorative procedure. Heart rate (HR) was measured when each child sat in the dental chair, after the removal of carious tissue, and after the removal of acupressure.
Results:
After the procedure, HR (as an indicator of anxiety) was statistically significantly lower in group B than group A (p = 0.02). However, there was no significant difference between the groups regarding anxiety before and during the restorative procedure (VPTm and HR: p > 0.05).
Conclusion:
The children who received acupressure on documented points for the reduction of anxiety had a significantly lower HR after the restorative procedure. No significant between-group difference was found regarding anxiety measured using a psychometric evaluation (VPTm).
