Study summary

This randomized, multicenter, open-label trial evaluates whether preoperative dental screening improves outcomes in patients undergoing surgical or transcatheter cardiac valve intervention. Participants are randomized 1:1 to preoperative dental screening or no screening. The primary outcome is time to first occurrence of all-cause death, redo-intervention of the index valve, or definite infective endocarditis within 2 years. The study uses registry-based follow-up to ensure complete outcome ascertainment.

Read the detailed description

Infective endocarditis is associated with high morbidity and mortality in patients with prosthetic heart valves. Current recommendations for preoperative dental screening are based on observational data, and randomized evidence is lacking.

This is a pragmatic, multicenter, randomized controlled trial conducted in Sweden. Patients accepted for surgical or transcatheter valve intervention are randomized 1:1 to:

  • Preoperative dental screening
  • No preoperative dental screening

Dental treatment in the intervention group is performed according to clinical practice. No routine dental screening is performed in the control group.

The primary endpoint is a composite of all-cause death, redo-intervention of the index valve, and definite infective endocarditis within 2 years.

All analyses will follow the intention-to-treat principle using time-to-event methods.

In context

Endocarditis

173 studies on the registry are indexed under Endocarditis; 57 are open to participants now.

This study's planned enrollment of 1,300 is above the median of 92 across 86 interventional studies indexed under Endocarditis.

  • Able to provide

Exclusion criteria

Exclusion Criteria:

  • Previous or ongoing infective endocarditis

  • Inability to provide
  • Expected loss to follow-up
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Composite outcome of death, redo-intervention, or infective endocarditis

    Time to first occurrence of all-cause death, redo-intervention of the index valve, or definite infective endocarditis.

    Time frame: 2 years

Secondary outcomes

  1. All-cause mortality

    Time frame: 2 years

  2. Redo-intervention of index valve

    Time frame: 2 years

  3. Definite infective endocarditis

    Time frame: 2 years

  4. CIED extraction

    Extraction of Cardiovascular Implantable Electronic Device (CIED)

    Time frame: 2 years

  5. Oral health (GOHAI score)

    The GOHAI consists of 12 items with a total score ranging from 12 to 60, where higher scores indicate better oral health-related quality of life.

    Time frame: 3 months

  6. Quality of life (EQ-5D-5L index and VAS score)

    The EQ-5D-5L descriptive system generates an index value typically ranging from less than 0 (worse than death) to 1 (full health), where higher values indicate better health-related quality of life. The EQ Visual Analogue Scale (EQ VAS) ranges from 0 to 100, where higher scores indicate better perceived health.

    Time frame: 3 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started May 2026 (actual). Primary completion is estimated for Dec 2030, 54 months after the start.

Of 34 interventional studies with no phase under Endocarditis, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 59. This study's planned 54 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 19, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
