WELCOME TO THE SCRiPT STUDY

Selective Caries Removal in Permanent Teeth

The Selective Caries Removal in Permanent Teeth Trial (SCRiPT)

The participant recruitment phase of the SCRiPT Study is now complete and the study continues in the participant Follow-up phase. SCRiPT’s new end date is 28 February 2026. The results of the study will be published after that date. The SCRiPT study question compares two treatments for deep tooth decay in the teeth towards the back of the mouth (molars and pre molars). The results of the study will help shape the future of dental care and hopefully ensure that our teeth last longer.

For further information or if you have any questions about SCRiPT please contact us via the study email address: script@dundee.ac.uk.

We are inviting members of the public who have had treatment for severe toothache or recently had dental decay treatment to join a Patient and Public Involvement Group to share their experience and give their opinion on how we give information to other dental patients. Please scroll down for further details or contact us at script@dundee.ac.uk.

What is SCRiPT?

The SCRiPT study is testing two treatments for deep tooth decay. We know both treatments work. However, we don't know which treatment is best overall for patients and for the NHS. The NHS has funded this research project so we can collect information on a large group of people having both types of treatment. At the end of the study we will report which treatment is best.

Who gets tooth decay? Tooth decay is very common. Most teenagers and adults will have some decay in their back teeth. Treating tooth decay (dental caries) costs the NHS over £3.4 billion each year.

How is deep tooth decay usually treated? There are different ways of treating teeth with decay where the decay has spread deep into the tooth close to the nerve.

The most common way is to take away all of the decay before placing a filling in the tooth. This is known as "complete decay removal" or complete caries removal (CCR). When removing all the decay there is a small chance of serious damage to the nerve. Such damage makes root canal treatment or tooth loss (extraction) likely. Also drilling the tooth to remove all the decay can weaken the tooth so it is more likely to break and need further treatment.

Dentists want to compare the complete removal of decay with a new way that does not remove all of the decay. In the new way, the dentists select only some of the decay for removal and a filling is then put in to stop the decay from getting worse. This is known as "selective decay removal" or selective caries removal (SCR). There is no chance that the nerve will be damaged when only some of the decay is taken out. If only some of the decay is taken out it is possible that the tooth will still need more treatment later. There is research in children's teeth that supports this new way. However, there are gaps in our knowledge about selective decay removal in adult teeth.

What is the aim of the SCRiPT study? The SCRiPT study will test "selective decay removal" compared to "complete decay removal" to find out if follow-up treatment was needed, the costs of this follow-up, the pain experienced by the patients and the impact on their lives.

Who is taking part in the study? The participant recruitment phase is now complete. We invited people over 12 years old to take part if they had one or more teeth that had deep decay which could be treated with a filling, and the patient received some or all of their treatment on the NHS.

People taking part have been given one of the two treatments for their deep caries – either selective decay removal or complete decay removal. A computer allocated which treatment they got. They are being followed up as normal by their dentists. Information about their teeth and their routine follow-up visits to their dentist is being collected. People taking part were asked to fill out a questionnaire about their health and their teeth when they started the study and will be asked again 1, 2, and 3 years afterwards.

Where can I find out more? Please download the patient information leaflet on this website which gives more information..

Who is running the study? The study is run by a team of experts in running dental research, led by Prof Jan Clarkson from the University of Dundee. Researchers from the University of Aberdeen and University of Sheffield are also involved. We also have patients and the public in our research teams to help us make sure that the important views of patients are included. The study is funded by the National Institute for Health Research (Health Technology Assessment project reference 17/127/07)
