Pain and Placebo Analgesia. Does Extended Information About Dental Procedures Reduce Pain Induced by Dental Treatment?

Not Applicable

Completed

• Conditions: Anxiety; Odontophobia
• Interventions: Other: anesthetics and extended information before dental treatment; Other: anesthetics and standard information before dental treatment

• Registration Number: NCT02160028
• Lead Sponsor: Norwegian University of Science and Technology

Brief Summary

Information about the effectiveness of treatment has been found to reduce pain, termed placebo analgesia. In this study it will be investigated whether this finding translates to the dental clinic. It will be investigated whether information that suggested that minimal pain will be experienced during filling therapy, can reduce the pain associated with that procedure compared to a group that receives standard information. All patients will receive the same amount of anesthesia and similar procedures during filling therapy. It is predicted that extended information should reduce pain, and that the reduction in pain should be associated with a reduction in stress.

Arm && Interventions

Group	Intervention	Description
Extended information	anesthetics and extended information before dental treatment	This group is given anesthetics and extended information before dental treatment about the anesthetics.
Standard information	anesthetics and standard information before dental treatment	This group is given anesthetics and standard information before dental treatment about the anesthetics.

Primary Outcome Measures

Name	Time	Method
Reduction of pain	1 hour	Pain intensity and pain discomfort will be measured by a VAS (Visual Analog Scale). The patients will report their experience of these factors verbally, four times during the treatment session.

Secondary Outcome Measures

Name	Time	Method
Reduction of stress	One hour	Stress is also measured using the VAS, i.e. using the same method as for pain. Stress or sympathetic activation is measured by using scin conductance on fingers (V-Amp (Brain Products, Munich, Germany).
