About this study
Official title: Clinical Performance of Indirect Adhesive Restorations Luted With Light-cured Composite Resin
Clinical performance of indirect adhesive restorations - onlays, overlays- luted with light-cured composite resin will be evaluated.
Read the detailed description
Indirect adhesive restorations are indicated in large Class II defects, replacement of large compromised existing restorations or endodontically treated teeth where cuspal protection is required. The need to perform adhesive restorations of posterior teeth is not only linked to esthetic purposes, but also have possibility of strengthening the remaining tooth structure. Indirect technique decreases polymerization shrinkage, reduces microleakage and also improves the marginal seal when comparing direct resin composites. Furthermore, it provides improved physical and mechanical properties, ideal occlusal morphology, more precise control of proximal contours and contacts. Indirect adhesive restorations are classically delivered with an adhesive procedure including dual-cure cement. Updated approaches now include the use of composite resins as luting agent.
This study will be carried out as a prospective study, with assessment of the restorations after three years. PASS 11 Software was used to calculate the sample size. At least 77 indirect adhesive restorations will be included for this study. Patients referred to Istanbul Okan University Faculty of Dentistry between 2016-2017 who had returned for the baseline recall and at least one year recall after the treatment will be invited for eligibility to participate in the study. 83 indirect adhesive restorations in at least 60 patients will be included. The patients who will not meet all the inclusion criteria will be excluded from the study. A signed informed consent form will be obtained from all patients before beginning the study.
Restorations will be evaluated clinically according to FDI World Dental Federation criteria. Three main groups- esthetic, functional, biological properties- and their sub-categorizes of FDI World Dental Federation criteria will be scored on a scale of 1 to 5. Statistical analysis will be performed using R (v.3.5.3) Software and the SIGN.test function in the BSDA package (p <0.05).

|---|---|---|
| Indirect restorations luted with light-cured composite resin. | Experimental | Subjects for the study will be identified from patients who had treated with indirect adhesive restorations onlay or overlay during the period 2016 to 2017 was performed at Istanbul Okan University Faculty of Dentistry by an experienced clinician.
Local anesthesia was applied if necessary. After caries and/or failed restorations were removed, the preparations were performed according to defined principles for adhesive onlays/overlays. At least one cuspal coverage was required for each restoration. All undercuts were eliminated using composite resin. Following the cavity preparation, immediate dentin sealing was applied and polymerized prior to impression taking. Indirect restorations were designed and fabricated with CEREC system. Surface treatments and clinical protocols were performed under manufacturer's instructions. Adhesive cementation with composite resin procedure was carried out with the rubber-dam isolation.

Questions about this trial
What is this clinical trial studying?
A study testing Indirect adhesive restoration of posterior teeth in people with Dental Caries and Endodontically Treated Teeth, run by Okan University 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 8 inclusion and 6 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 9 Apr 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 Gülşah Yenier, DDS, PhD (+905547810176, gulsahyenier@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Survival rate (time frame: at 5 years). 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 NCT04838483, which also lists 7 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 9 Apr 2021.
