What is PIP?

The PIP Study is looking at alternative ways to treat toothache and tooth decay.

Severe toothache and pain can be caused by tooth decay. Tooth decay is very common and treating decay costs the NHS over £3.4 billion each year. Where the tooth decay has spread deep into the nerve, this is usually treated by taking out the tooth or by Root Canal Treatment. Root canal treatment removes all the nerve from the tooth.

An alternative treatment for this kind of toothache is called a Pulpotomy. A Pulpotomy removes only the damaged part of the nerve, which can be a quicker and less invasive treatment.

Pulpotomy is already used on children’s teeth and on adult teeth when they are being treated in dental hospitals. However, it is not yet routinely used on adult teeth in NHS dental practices. We have recently conducted a PIP Feasibility Study where we took patients’ and dentists’ experiences of the new treatment (Full Pulpotomy) into account to assist us in planning the PIP Study. We successfully met the following criteria and in August 2022 NIHR advised that we can progress on to main study:

Recruited 21 GDPs in 13 practices ✔
Successfully trained all dentists ✔
68% of treatments reached Clinical Fidelity. Once we introduced feedback forms, Clinical Fidelity was then 100% ✔
100% satisfaction from responding participants ✔
0.9 eligible patients were seen per practice per month ✔

Now we are moving onto planning and recruitment for the full PIP Study, where we will recruit 50 dental practices in England and Scotland. The dentists will recruit 530 NHS adult (16 years and older) dental patients who have Irreversible Pulpitis in permanent premolar and molar teeth and who agree to take part.

PIP Study primary objectives are:

To compare the clinical success of Full Pulpotomy (FP) with Root Canal Treatment (RCTx) (no re-intervention or symptoms of pulpitis or apical periodontitis) at 1 year.
To compare the costs and benefits of Full Pulpotomy (FP) with Root Canal Treatment (RCTx) over a modelled life-time horizon.

PIP Study Secondary objectives are:

To evaluate radiographic success (absence of radiolucency in participant’s initial intervention), patient health related quality of life, dental pain, dental anxiety, satisfaction with care/treatment and adverse events at 1 year. Patient health related quality of life and dental pain at 7 days.
To determine general population preferences for treatment and outcomes and predict uptake, NHS and patient perspective costs; incremental net benefit over the study follow up; and incremental cost per QALY over the 1-year follow-up and extrapolated over a modelled lifetime horizon.
To explore the implementation of technologies and the mechanisms of impact including acceptability of interventions to patient and clinicians.

The PIP Study is a £1.9m multicenter randomised controlled study.

Key facts about the study and documents

I am a dentist – how do I join the study?

The PIP Study

The PIP study will compare the effectiveness of Full Pulpotomy and Root Canal Treatment for Irreversible Pulpitis in permanent premolar and molar teeth in adults. The study will take place in primary care dental practices across Scotland and England.

PIP Study

We will recruit 530 patient participants from 50 general dental practices in Scotland and England. We are looking for dental practices to recruit 11 adult patients (16 years and older) seeking treatment at NHS dental practices with symptoms indicative of Irreversible Pulpitis in a premolar/molar tooth with deep caries and or a deep restoration.

The patient must be willing to be randomly allocated (computer generated) to one of the two study groups – Full Pulpotomy or Root Canal Treatment.
The PIP Study will take place over 12 months and patient participants will be followed up by the PIP Study Team in Dundee at 7 days and then again by GDP at 1 year after treatment. Link to PIP Flyer

The NHS National Institute for Health Research Health Technology Assessment programme has commissioned a collaborative team from the Universities of Dundee, Aberdeen, Glasgow, King's College London, Liverpool, Sheffield, and NHS Education for Scotland to conduct this research.

If you are interested in being involved in this primary care research study, or would like further details, please contact us to arrange a short briefing to answer any questions you may have about involvement with PIP.

Participant Information

The University of Dundee is the sponsor for this study based in the United Kingdom. We will be using information from you and your dental records in order to undertake this study and, will act as the data controller for this study. This means that we are responsible for looking after your information and using it properly. We will keep identifiable information about you for at least 5 years after the study has finished.

This information will include your name, contact details, date of birth, NHS number and CHI number (Scottish participants only). People will use this information to do the research or to check your records to make sure that the research is being done properly.

We will collect relevant data (e.g. about visits to the dentist and treatment to teeth) via NHS central registers. The reason for this is to make sure that we have the correct information about all the participants taking part in this study and ensure that the results are as accurate as possible. In order to do this, we will securely send the NHS central registers some information about you (e.g. date of birth, hospital number, name, address, CHI number (Scottish participants only). They will then match this information to their records and use your study number to securely send any relevant data back to the PIP Study Office.

People who do not need to know who you are will not be able to see your name or contact details. Your data will have a code number instead. We will follow ethical and legal practice and all information which is collected about you for the purpose of this research study will be handled in strict confidence and securely stored by the University of Aberdeen.

Your rights to access, change or move your information are limited, as we need to manage your information in specific ways in order for the research to be reliable and accurate. If you withdraw from the study, we will keep the information about you that we have already obtained. To safeguard your rights, we will use the minimum personally-identifiable information possible.
