About this study
The objective of this study is to evaluate the clinical safety and performance of Optibond Universal (OBU), a single component universal dental adhesive intended for indirect dental restorations according to manufacturer's Instruction For Use.
Read the detailed description
The device used in the study, Optibond Universal (OBU) is a single component universal dental adhesive intended for direct and indirect dental restorations. OBU is formulated to provide reliable bond strength with any etch technique, on all common substrates and in combination with any resin cement without auxiliary products (silane or metal primers) even in absence of light. OBU is intended for general population use by a dental professional.
OBU contains an acidic component to etch the tooth surface in order to allow the adhesive to mechanically adhere to the prepared tooth surface. The adhesive can be used with light or without light cured prior to application of the restorative material. This allows for the adhesive to mechanically and chemically bond to the applied restorative material. OBU is formulated to provide a reliable bond strength, and it's compatible with all etching modes (self-etch, selective etch, and total etch).
Aim/Hypothesis/Objective The primary objective of this study is to evaluate the clinical performance of OBU used in the intended clinical conditions.
The device will undergo evaluation in the following categories:
Functional Properties Endodontic posts Ceramic restorations Composite and metal crowns Pretreatment for indirect restorations Core build-ups
Endpoints:
Primary endpoints:
Evaluation of clinical safety and performance of OBU, a single component universal dental adhesive intended for indirect dental restorations according to manufacturer's Instruction For Use.
(Indirect metal restoration is defined as any restoration made of precious or non-precious alloy such as inlays, onlays, porcelain fused to metal, metal full coverage crown, metal full coverage fixed partial denture). All implant restorations are excluded.
Secondary endpoints:
Post-operative sensitivity, retention, general periodontal health, and general optical properties after baseline, 6 months, 1 year and 2 years post-placement.
The hypothesis to be tested is that OBU is safe and effective in clinical settings when the device is used according to manufacturer's instructions:
H0: P ̂_T-P ̂_C≥ ∆ HA: P ̂_T-P ̂_C< ∆ Where ∆ (delta) refers to the non-inferiority margin set at 10%.

Questions about this trial
What is this clinical trial studying?
A study testing Optibond Universal in people with Sensitivity, Tooth, run by Kerr Corporation at 1 site in United States.
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 6 inclusion and 16 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: stopped early, as of the sponsor's last update on 12 Feb 2024. 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 United States. 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 was stopped early (reason given: Study halted prematurely and will not resume; participants are no longer being examined or receiving intervention.). Results are not available in the source record.
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?
Sensitivity Questionnaire-Visual Analog Scale 0 to 10 (0=No pain, 10=Worst pain possible) (time frame: Screening). The study lists 11 primary outcomes in all. 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 NCT06002880, which also lists 3 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 12 Feb 2024; AzTrials last refreshed its copy on 8 Nov 2026.
