WELCOME TO THE SCRiPT STUDY

Selective Caries Removal in Permanent Teeth

An update on the Selective Caries Removal in Permanent Teeth Trial (SCRiPT)

The study is open and some participating dental practices have started participant recruitment. There has been considerable interest from dentists in the SCRiPT study question which compares two treatments for deep tooth decay in the teeth towards the back of the mouth (molars and pre molars) . The results of the SCRiPT study will help shape the future of dental care and hopefully ensure that our teeth last longer.

COVID 19 restrictions have not changed either of the two treatments being compared in the SCRiPT study.

We would like to thank all the dental practices that have contacted us to date for their engagement and enthusiasm for the SCRiPT study.

For further information or if you have any questions about SCRiPT please contact us via the study email address: 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 can take part in the study? People over 12 years old can take part if they have teeth that have deep decay which can be treated with a filling, and if this treatment would normally be done on the NHS.

What does taking part in the study involve? People taking part will be given one of the two treatments for their deep caries – either selective decay removal or complete decay removal. A computer will allocate which treatment they get but they will always get a filling. They will be followed up as normal by their dentists. Information about their teeth and their routine follow-up visits to their dentist will be collected. People taking part will also be asked to fill out a questionnaire about their health and their teeth when they start the study and 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 about what taking part would involve. You can find out if your dentist is taking part by checking out the "Where can I take part" section below which will be regularly updated.

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)
