Pain of dental anaesthetic injection

▸ 

Crossover randomised controlled trial (RCT) (n=49).

Methods

Children scheduled for dental treatment using local anaesthesia received bilateral acupuncture at LI4 using indwelling fixed needles (Pyonex, 1.5 mm long, 0.2 mm diameter). This was started 5  min before the standardised anaesthetic procedure; the parents stimulated the needles by massage throughout. In repeat visits to the dentist, children were crossed over between acupuncture and no acupuncture.

Pain intensity during local anaesthetic injection, assessed by the patient with the Verbal Rating Scale, or Faces Pain Scale (0–10) for younger children, was the primary endpoint. Parent- and dentist-assessed pain intensity and heart rate were also recorded.

Results

From 72 children, 49 completed the study but the dropout rate was not related to acupuncture. As shown in figure 1, children reported less pain when acupuncture was used (p<0.001). Their heart rate was also lower. The differences in pain scored by parents and dentists were not significant.

Sham-controlled RCT (n=76).

Methods

One hundred and twenty women who had just had a normal spontaneous birth with epidural anaesthesia were included in a single-blind randomised trial. Women were randomly assigned to receive true or sham acupuncture immediately after the cord was clamped. Controlled cord traction was not used.

In the first group, a single needle …
