Study summary

Objectives: The main objective of the study is to investigate

  1. How many patients will attend and complete dental care if they are offered it for free during the stay at "The department of substance abuse treatment, University Hospital North Norway (UNN) in Narvik".
  2. Explore whether a parallel dental treatment in addition to the other treatment at the department has a beneficial effect on the abuse treatment, or whether it can be disruptive to offer dental treatment in combination with admission for drug rehabilitation?
Read the detailed description

This is a non-randomized clinical study without a control group. Approximately 50 persons admitted to "The department of substance abuse treatment (Russeksjon UNN Narvik)" will be offered free dental service during treatment for drug addiction.

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 Apr 2022 (actual). Primary completion is estimated for Dec 2025, 44 months after the start.

Of 814 non-industry interventional studies with no phase under Substance-Related Disorders, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 53. This study's planned 44 months is above that.

Counting every sponsor, half of 854 studies reached it within 34 months; a quarter within 17 and three quarters within 53.

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 Nov 4, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
