TL;DR: The results lend support to the assumption that dentally fearful patients with a disposition to high anxiety sensitivity amplify pain anticipations when exposed to the critical situation.
Abstract: – Objectives: The personality disposition to anxiety sensitivity refers to beliefs about negative consequences of bodily arousal. The concept has recently been successfully applied in research on chronic pain conditions. The present study investigated whether anxiety sensitivity interacts with dental fear to increase expected and experienced pain during routine dental treatment.
Methods: Subjects were 97 patients undergoing dental procedures of excavation and filling. Anxiety dispositions were measured by the Anxiety Sensitivity Index and the Dental Anxiety Scale. Expected and experienced pain were assessed by affective and sensory verbal descriptor scales and a numerical rating scale measuring pain intensity.
Results: Dentally fearful patients scoring high in anxiety sensitivity both expected and experienced more pain than low scorers did. Significant interactions were found predicting expected affective and intense pain and experienced pain intensity.
Conclusion: The results lend support to the assumption that dentally fearful patients with a disposition to high anxiety sensitivity amplify pain anticipations when exposed to the critical situation. When dentally fearful patients are under treatment, their beliefs about negative consequences of bodily arousal may negatively influence their evaluation of treatment related pain.

TL;DR: In this sample, dental anxiety was not related to gender, age, educational level and family income; however, a previous traumatic event was related to dental anxiety, and there was no association between salivary cortisol concentrations and gender or dental anxiety.
Abstract: Dental anxiety is still prevalent, despite advances in treatment, and affects the utilization of health care services. The purpose of this cross-sectional study was to determine if patients with different degrees of dental anxiety and pain undergoing emergency dental care have different stress reactions as measured by salivary cortisol. Seventy three patients completed the modified dental anxiety scale (MDAS), and described any previous dental traumatic experience. Their socio-demographic characteristics were also recorded. They also rated pain intensity on a 100 mm visual analogue scale (VAS). A saliva sample was collected before the procedure, and analyzed by enzyme immunoassay. Thirty patients were dentally anxious and forty one complained of pain. In this sample, dental anxiety was not related to gender, age, educational level and family income; however, a previous traumatic event was related to dental anxiety. There was no association between salivary cortisol concentrations and gender or dental anxiety. Patients with pain showed higher cortisol levels. When gathering patient information, the dentist should note patients' negative dental experiences in order to provide more effective, less traumatic treatment. (J Oral Sci 51, 515-520, 2009)

TL;DR: Interventions for early-onset dental fear should aim to modify both the dental fear and the personality vulnerabilities that may contribute to the development of dental fear early in the life-course.

TL;DR: Men show a larger cortisol response to a noxious stressor than women that is not attributable to sex differences in subjective pain, and the conclusion of a causal relation between larger cortisol responses and higher pain tolerance thresholds in men is tempting but yet speculative.
Abstract: Objectives Evidence has accumulated that men and women show different responses to noxious stimuli, with women exhibiting greater sensitivity to pain than men. Data concerning sex differences in cortisol response patterns have revealed inconsistent results so far. The purpose of the present study was to examine sex differences in subjective pain and cortisol response to a noxious stressor. Methods Seventy-six subjects (39 male and 37 female) were investigated by a modification of the cold pressor test that consisted of intermittent immersion of the hand into ice water (plunge test, PT). The PT was conducted twice, in consecutive trials, to guarantee a sufficient exposure to the noxious stressor for eliciting cortisol responses. In each trial, tolerance time and pain ratings visual analog scale (VAS) were assessed. Seven saliva samples (c1-c7) were collected to determine cortisol levels at baseline (c1-c2), directly before (c3) and 20 minutes after noxious stress (c4), and during recovery period (c5-c7). Results We found no significant sex differences in tolerance time in trial 1, but highly significant differences in tolerance time in trial 2, with higher tolerance times in men. No significant sex differences were found for the VAS ratings of pain intensity and unpleasantness in the 2 trials. In contrast, a significantly larger cortisol increase in men was observed compared with women. Analysis of covariance revealed that this result could not be attributed to sex differences in cortisol level at baseline and in tolerance time. Discussion The present study demonstrates that men show a larger cortisol response to a noxious stressor than women that is not attributable to sex differences in subjective pain. The conclusion of a causal relation between larger cortisol responses and higher pain tolerance thresholds in men is tempting but yet speculative.

TL;DR: It is suggested that patients feel stronger pain if anxiety in the treatment environment is high and that it is, therefore, important to reduce anxiety during treatment to reduce pain.
Abstract: The purpose of this study was to clarify the effects of anxiety about dental treatment on pain during treatment. Subjects consisted of 57 consenting sixth-grade students at Tokyo Dental College (male: 32, female: 25), all of whom participated in this study during their clinical training program. They knew how third molars were extracted and all had experience of assisting in tooth extraction. Prior to the study, trait anxiety in the subjects was evaluated according to the State-Trait Anxiety Inventory (STAI, Japanese version). The students were asked to read one of two scenarios describing a scene in which a third molar was extracted while imagining themselves to be the patient. Scene 1 is set in an “environment where the patient feels safe and comfortable,” and the Scene 2 is set in an “environment where the patient feels strong anxiety”. The subjects were asked to imagine the anxiety and pain in that scenario and evaluate that pain according to a visual analogue scale (VAS). Two scenarios were randomly shown to the subjects in a crossover manner. No significant correlation between trait anxiety and preoperative anxiety was observed. There was no difference in level of preoperative anxiety for Scene 1 and Scene 2 between the high- and low-trait anxiety groups. This suggests that there was no relationship between sensitivity to anxiety as a characteristic of the subject and amplitude of anxiety immediately prior to treatment. Scene 2 elicited significantly higher anxiety before injection of regional anesthesia, significantly higher pain during insertion of the needle, and significantly higher pain during extraction of the tooth than Scene 1. This difference suggests that patients feel stronger pain if anxiety in the treatment environment is high and that it is, therefore, important to reduce anxiety during treatment to reduce pain.
