About this study

Official title: Clinical Performance of Diagnostic Methods in Early Occlusal Caries

The investigators aim will be to compare the diagnostic performance of clinical visual examination (ICDAS II), intraoral/bite wing radiography (BW), near infrared light transillumination (NIR-LT), and laser fluorescence (LF), in comparison to microcomputed tomography (micro-CT) for the detection of non-cavitated occlusal enamel and dentin caries in third molar teeth. Potential participants will be consecutively recruited.

Read the detailed description

Studies regarding comparison of diagnostic techniques for caries detection are generally conducted under in vitro conditions due to ethical concerns. Considering the many recently published in vitro studies which attempted to assess the diagnostic ability of different caries diagnosis systems, it is not possible to know at what rate in vitro findings are applicable to the clinical situation.The investigators would like to assess initial occlusal caries lesions by using different diagnostic methods under in vivo conditions. In the present study, the investigators will assess diagnostic accuracy of clinical visual examination (ICDAS II), digital intraoral radiography, near infrared light transillumination (NIR-LT), and laser fluorescence (LF), by examining third molar teeth in comparison to gold standard micro-CT images. The null hypothesis of the study is that no significant difference exists for the clinical performance of the evaluated methods in detecting non-cavitated occlusal caries in either the enamel or the dentin. This prospective study will include 101 third molars of 101 patients with non-cavitated occlusal caries requiring extraction. ICDAS II, BW, NIR-LT and LF examinations will be carried out by two examiners. Gold standard will be determined by micro-CT imaging after extraction. Intraclass correlation coefficient (ICC) value will be calculated for examiner agreement. Accuracy rate, sensitivity, specificity, predictive values and areas under receiver operating characteristic curves (Az) will be calculated. Clinical application time and patient comfort/pain analysis will be compared. Nonparametric variables will be assessed by Kruskal Wallis Test. Significance level will be set at p<0.05.

What is being measured

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

  1. Accuracy

    The accuracy of caries detection methods will be evaluated when compared to the gold standard Micro CT.

    Measured: 1 month

  2. Receptor operating characteristic (ROC) curves

    Receptor operating characteristic (ROC) curves (Az) will be calculated to show the caries distinguishing ability of each caries detection method and the observer.

    Measured: 1 month

  3. Intraclass correlation coefficient (ICC)

    Intra- and inter-observer reproducibility will be assessed by intraclass correlation coefficient (ICC).

    Measured: 1 month

Secondary outcomes (2)
  1. Patient comfort/pain analysis by using Visual Analog Scale (VAS)(comparative assessment of the tests):

    The patients will be asked to rate their feelings (based on comfort and pain) from absence of discomfort and pain to extreme discomfort and pain (between 0 and 10) for each clinical method.

    Measured: 1 month

  2. Clinical time efficacy (comparative assessment of the tests)

    Clinical application times from the beginning of the procedure to the end of the procedure for each method will be calculated by using a stopwatch. (example: LF pen 10 sn)

    Measured: 1 month

Questions about this trial

What is this clinical trial studying?

An observational study of Caries and Diagnoses Disease, run by Nazan Kocak Topbas at 1 site in Turkey (Türkiye).

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 9 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 1 Oct 2021. 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 Turkey (Türkiye). 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?

Results are not available in the source record.

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

Contact Nazan Koçak Topbaş, PhD (+905458297898, nazankocak@mersin.edu.tr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Accuracy (time frame: 1 month). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Oct 2021.
