About this study

Official title: Clinical Evaluation of Different Application Strategies When Using a Futurabond Universal Adhesive System in Class V Cavities

Treatment clinical trial, randomized, controled, parallel, double-blinded, with four groups, that aims to evaluate the best application strategy when using a new Universal Adhesive system, Futurabond Universal (VOCO GmbH, Germany). Volunteers will be selected and recruited,following inclusion criteria and pre-established exclusion. All volunteers will be informed and sign a term of clarification and consent. 50 enrolled patients will receive 200 Class V dental restorations, made in four different ways, one from each experimental group, using the same universal self-etching adhesive system, which is the tested material in this study. Non-carious cervical lesions will receive the applied adhesive system in 4 different protocols separated by groups. Group Self Etching (SET) (control): no conditioning, the adhesive system will be used in 50 teeth, according to the manufacturer's instructions, in the self-etching mode. The adhesive system will be brushed during 20 seconds in the cavity, will be air-dried during 5 seconds, and activated during 10 seconds with Light Emission Diode (LED) light; Group SEE (Selective enamel etching): 37% phosphoric acid will be applied during 30 seconds, only in enamel in 50 teeth. This acid will be removed using water, the cavity will be air-dried, and then, the adhesive will be applied according to the manufacturer's instructions, as described in group SET; Group ERDry (Etch\& Rinse Dry): 37% phosphoric acid will be applied during 30 seconds, only in enamel and during 15 seconds only in dentin, in 50 teeth. This acid will be removed using water, the cavity will be air-dried, keeping dentin dry, and then, the adhesive will be applied according to the manufacturer's instructions, as described in group SET; Group ERWet (Etch\& Rinse Wet): 37% phosphoric acid will be applied during 30 seconds, only in enamel and during 15 seconds only in dentin, in 50 teeth. This acid will be removed using water, the cavity will be air-dried, keeping dentin wet, and then, the adhesive will be applied according to the manufacturer's instructions, as described in group SET. After applying the adhesive, the restorations will be made with composite resin, and evaluated every 6 months for pain assessment, shape, staining or recurrent caries, using scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.

Read the detailed description

This is a Treatment clinical trial, randomized, controlled, parallel, double-blinded, with four groups, that aims to evaluate the best application strategy when using a new Universal Adhesive system, Futurabond Universal (VOCO GmbH, Germany). Volunteers will be selected and recruited,following inclusion criteria and pre-established exclusion. All volunteers will be informed and sign a term of clarification and consent. All 50 enrolled patients will receive Class V dental restorations, made in four different ways, one from each experimental group, using the same universal self-etching adhesive system, which is the tested material in this study. All patients must have at only 20 teeth in function, must have at only 2 non carious cervical lesions (NCCL), in different teeth, that need restoration. Those lesions must be non carious, must be more than 1 mm deep, should have exposed dentin, and must have at only 50% of margins in enamel. Teeth should not present periodontal mobility. Firstly, the patient will be anesthetized locally with 3% Mepivacaine solution, followed by prophylaxis with pumice powder and water. All cavities will be washed and dried after these procedures for optimal selection of color, using a color scale. Then, the rubber dam isolation of the teeth to be restored will be held. Non-carious cervical lesions will receive the applied adhesive system in 4 different protocols separated by groups. Group Self Etching (SET) (control): no conditioning, the adhesive system will be used in 50 teeth, according to the manufacturer's instructions, in the self-etching mode. The adhesive system will be brushed during 20 seconds in the cavity, will be air-dried during 5 seconds, and activated during 10 seconds with Light Emission Diode (LED) light; Group SEE (Selective enamel etching): 37% phosphoric acid will be applied during 30 seconds, only in enamel in 50 teeth. This acid will be removed using water, the cavity will be air-dried, and then, the adhesive will be applied according to the manufacturer's instructions, as described in group SET; Group ERDry (Etch\& Rinse Dry): 37% phosphoric acid will be applied during 30 seconds, only in enamel and during 15 seconds only in dentin, in 50 teeth. This acid will be removed using water, the cavity will be air-dried, keeping dentin dry, and then, the adhesive will be applied according to the manufacturer's instructions, as described in group SET; Group ERWet (Etch\& Rinse Wet): 37% phosphoric acid will be applied during 30 seconds, only in enamel and during 15 seconds only in dentin, in 50 teeth. This acid will be removed using water, the cavity will be air-dried, keeping dentin wet, and then, the adhesive will be applied according to the manufacturer's instructions, as described in group SET. After applying the adhesive, the restorations will be made with composite Admira Fusion (VOCO GmbH, Germany), and evaluated every 6 months for pain assessment, shape, staining or recurrent caries, using scores. To determine in which group each tooth will be enrolled, the authors will randomize the teeth.

A study testing Self-Etching Application Strategy, Enamel Etching Application Strategy and Etch&Rinse Dry Application Strategy in people with Dental Restoration Failure of Marginal Integrity, run by Universidade Federal Fluminense at 2 sites in Brazil.

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 1 inclusion and 1 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: under way, not looking for participants, as of the sponsor's last update on 15 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Brazil. 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?

This study is still under way. Results are not available in the source record yet.

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?

Restoration Loss (time frame: Four 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 NCT03244124, which also lists 13 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 15 May 2026.
