About this study

Official title: The CAP-1 Trial: Effect of Stepwise Versus One Completed Excavation in Deep Caries in Permanent Teeth: A Randomised, Patient - and Observer-blinded Multicenter Trial

Brief summary

Background:

Read more

A large proportion of dental practice involves the treatment of caries in the permanent dentition. In USA alone tooth related pain is annually responsible for 15 billions days lost through sickness. We do not know whether a stepwise excavation is better or worse compared with one final completed excavation in adults with deep caries with or without pain. A deep carious lesion is in the risk zone of being pulpal exposed during excavation.

Aim:

The aim of the CAP-1-trial is to investigate the beneficial effects of stepwise excavation during two visits versus óne completed excavation of deep caries in permanent teeth with or without pain.

Patients:

Consecutive patients contacting the units involved in the CAP trial for the treatment of deep caries. The trial will comprise 300 patients.

Design:

CAP-1-trial is a randomised patient- and observer-blinded multicenter trial, with two parallel intervention groups. Patients that fulfill the inclusions criteria and none of the exclusions criteria, will be centrally bloc-randomised in Copenhagen Trial Unit, Copenhagen DK, and stratified by age and pain. Allocation ratio is 1:1.

Interventions and products:

Patients are allocated for stepwise excavation in two visits or final excavation in one visit. The patients will not be informed about the result of the randomisation, i.e. the type of intervention. Therefore, all patients will be contacted for two visits. The second visit in the stepwise excavation group wil be used for the second and final excavation, and for the performance of a permanent restoration. The second visit in the one step excavation group will solely be used for the performance of a permanent restoration. The interventions in both groups are completed following 8-10 weeks after the randomisation.

A temporary calcium hydroxide based material is used in both groups (Dycal®). The temporary restoration material, glas-ionomer cement is used (Ketac Molar®) in between visits, and a resin material is used for the final restoration(Herculite®).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary outcome is whether the treatment can be made with a maintained sensible pulp and without root infection following a 1-year control.

    In this update we have also completed 5 yr control

    Measured: 1year control data for all treatments primo 2008

Secondary outcomes (1)
  1. Secondary outcome constitutes pain intensity using a visual analogue scale measured before the first visit and 1 and 7 days after.

    Measured: ultimo 2007

Questions about this trial

What is this clinical trial studying?

A study testing SW and DCE in people with Dental Caries and Reversible Pulpitis, run by University of Copenhagen at 1 site in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary outcome is whether the treatment can be made with a maintained sensible pulp and without root infection following a 1-year control. (time frame: 1year control data for all treatments primo 2008). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00187837, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Oct 2016.
