In a demographic survey, 300 residents of a German city were questioned to determine the prevalence of dental anxiety. The correlation between the amount of dental anxiety and the age, sex, and education of the subjects was examined and the reasons for avoiding dentist's appointments, the duration of this avoidance, and what the subjects desire from future dental treatment. The Hierarchical Anxiety Questionnaire (HAQ) was used to measure the amount of dental anxiety. The average level of anxiety was 28.8+/-10.1 according to the HAQ. Young people were more afraid than older people (p=0.007), and women were more anxious than men (p=0.004). Of the women, 72% go to the dentist regularly, but only 60% of the men do (p=0.020). A painful experience while receiving dental treatment was given by 67% as the main reason for their dental anxiety, followed by a fear of needles (35%). The people wished for the most accurate information available about the dental treatment they receive (69%), followed by a compassionate dentist (62%), and treatment that is free of pain (62%). Of the people, 11% [95% CI: (7.5%; 14.5%)] suffer from dental phobia. All dental phobics were able to state the cause of their fear and more urgently wished for help from the dentist in overcoming their anxiety than the non-phobics (p=0.030). To satisfy the needs of the phobic patients, it appears necessary to screen the phobics out of the group of all patients and then offer them adequate therapy, or refer these patients to specialised treatment centres.

Although medical interventions play an important role in preserving lives and maternal comfort they have become increasingly routine in normal childbirth. This may increase the risk of associated complications and a less satisfactory birth experience. Antenatal hypnosis is associated with a reduced need for pharmacological interventions during childbirth. This trial seeks to determine the efficacy or otherwise of antenatal group hypnosis preparation for childbirth in late pregnancy. METHODS/DESIGN: A single centre, randomised controlled trial using a 3 arm parallel group design in the largest tertiary maternity unit in South Australia. Group 1 participants receive antenatal hypnosis training in preparation for childbirth administered by a qualified hypnotherapist with the use of an audio compact disc on hypnosis for re-enforcement; Group 2 consists of antenatal hypnosis training in preparation for childbirth using an audio compact disc on hypnosis administered by a nurse with no training in hypnotherapy; Group 3 participants continue with their usual preparation for childbirth with no additional intervention. Women > 34 and < 39 weeks gestation, planning a vaginal birth, not in active labour, with a singleton, viable fetus of vertex presentation, are eligible to participate. Allocation concealment is achieved using telephone randomisation. Participants assigned to hypnosis groups commence hypnosis training as near as possible to 37 weeks gestation. Treatment allocations are concealed from treating obstetricians, anaesthetists, midwives and those personnel collecting and analysing data. Our sample size of 135 women/group gives the study 80% power to detect a clinically relevant fall of 20% in the number of women requiring pharmacological analgesia - the primary endpoint. We estimate that approximately 5-10% of women will deliver prior to receiving their allocated intervention. We plan to recruit 150 women/group and perform sequential interim analyses when 150 and 300 participants have been recruited. All participant data will be analysed, by a researcher blinded to treatment allocation, according to the "Intention to treat" principle with comprehensive pre-planned cost- benefit and subgroup analyses. DISCUSSION: If effective, hypnosis would be a simple, inexpensive way to improve the childbirth experience, reduce complications associated with pharmacological interventions, yield cost savings in maternity care, and this trial will provide evidence to guide clinical practice.

Hypnosis has been used in obstetrics for more than a century. However, with increasing numbers of women looking for alternative coping strategies for use during labour, the birth of a new discipline, HypnoBirthing, is gaining in popularity. HypnoBirthing is a hypnotherapy programme specifically designed for birth, employing the principles and techniques of hypnosis and self-relaxation. This article explains the philosophy and principles of HypnoBirthing, the evidence base and its physiological impact on labouring women, brought to life by real accounts.
