Background and study aims
Dental anxiety and avoidance of dental care due to anxiety cause major problems for both patients and dentists. Various distraction methods are used in daily medical practice to help patients cope with unpleasant procedures, but there is evidence that Virtual Reality (VR) distraction is more effective than other distraction methods. The main aim of the project is to find out if the use of VR during dental treatment can improve the overall dental experience and recollections of treatment for patients, breaking the negative cycle of memories of anxiety leading to further anxiety, and avoidance of future dental appointments. Additionally, the aim is to test whether the use of VR is suitable for dental patients with all levels of dental anxiety. The third aim is to test if the content of the VR distraction can make a difference by comparing two types of virtual environments, a natural area and an urban area.
Who can participate?
Patients who are scheduled to undergo dental treatment will be invited to take part in the
study.
What does the study involve?
After the pre-operative treatment appointment or annual check-up, patients will complete an initial questionnaire. During the dental treatment visit, the patient might be asked to wear some special goggles that will enable watching a VR scene. Whether a patient will be allocated to a VR group or a control group will be decided by a process called 'randomisation', which is like a coin toss. Following the appointment the patient will complete a questionnaire about the treatment experience. Patients will receive a phone call one week after treatment and will be asked to answer a few more questions.
What are the possible benefits and risks of participating?
We cannot promise the study will help you, but the information from this study may help improve the care provided to patients who experience anxiety regarding dental treatment in the future. However, some people may find that their dental experience is more pleasant and induces less anxiety than usual. There is little physical risk to participants involved in this project. Using the VR goggles and controller will not be for a long enough period to become a problem. Some people may have feelings of nausea when using the VR system. Patients will be informed that this may occur and that they should inform the dentist if they start feeling nauseous so the VR session can be stopped. Withdrawal during dental treatment won't affect the dental treatment; it only involves taking the VR goggles off the patient and taking back the controller from the patient. Patients are informed that they are free to withdraw at any time and without giving a reason. A decision to withdraw at any time, or a decision not to take part, will not affect the standard of care they receive.
Where is the study run from?
The study takes place at Torrington Dental Practice in Greater Torrington, UK.
When is the study starting and how long is it expected to run for?
It is anticipated that recruitment will start in August 2013 and finish by the end of 2014.

| Scientific title | The effects of virtual reality distraction during dental treatment: a first test of the elaborated intrusions account |
| Study objectives | It is hypothesised that exposure to virtual reality during dental treatment will lead to improved recollections of treatment and an overall improved dental experience. On 06/02/2014 the overall trial end date was changed from 31/12/2013 to 31/12/2014. |

| Health condition(s) or problem(s) studied | Dental treatment and anxiety |
| Intervention | Patients will be randomised to three groups: Two intervention groups: Two VR interventions will be investigated in this study. The first VR environment consists of a simulation of a natural area. The second VR environment consists of a simulated urban environment. In both groups, patients will be wearing VR goggles and will use a one-handed controller to navigate the environment. Control group: The patients in the control group will receive standard care |
| Intervention type | Other |
| Primary outcome measure | 1. The memories of patients about the dental treatment one week after treatment, consisting of 1.1. Remembered pain 1.2. Intrusive thoughts 1.3. Vividness of memories 2. Dental experience 3. Treatment experience 4. VR experience |
| Secondary outcome measures | 1. Treatment experience [pain, discomfort, stress - self-reported questionnaire and a physiological indicator (heart rate, measured with a pulse oximeter), time perception, perceived control] 2. Dental experience (communication with dentist, revisit intentions and likeliness of avoidance, dental anxiety, treatment satisfaction) 3. VR experience (presence, perceived restoration, attractiveness, environmental awareness, nausea, intention to use VR) All outcomes are measured using self-reported questionnaires. |

Eligibility
| Participant type(s) | Patient |
|---|---|
| Age group | Adult |
| Lower age limit | 18 Years |
| Sex | Both |
| Target number of participants | 120 |
| Key inclusion criteria | All patients, 18 years or older, who are scheduled to undergo dental treatment for fillings and/or extractions with a planned maximum treatment length of 30 minutes are eligible to participate in the study. This includes both referred patients and in-house patients. Both patients who need relative analgesia (RA) and who are treated without sedation will be included. |
| Key exclusion criteria | 1. Patients who need intravenous sedation 2. Patients who had epileptic seizures in the past cannot participate in the study due to the very small risk an episode can be triggered by using the HMD, similar to what may happen if they are exposed to a television 3. If a patient is scheduled for more than one treatment during the trial period, the patient will only be included for the first treatment |
