GOTHENBURG, Sweden: Pain or fear of pain during dental treatment, whether it be from anaesthetic injections, tooth extraction or orthodontic treatment, is stressful for many patients. In a pilot study, researchers from the University of Gothenburg investigated a patient group that might not yet be able or confident enough to express this stress—adolescents. Therefore, they tested a device to detect stress indicators during dental care in order to raise dental professionals’ awareness and allow intervention.
