About this study

Official title: Evaluation of Two Resin Composites and Two Adhesives for a Novel Surgical-restorative Protocol for the Treatment of Non-carious Cervical Lesions Associated With Gingival Recession: a Randomized Controlled Clinical Trial

Non-carious cervical lesion is frequently associated with gingival recession, resulting in a combined lesion that has a different treatment prognosis when the two lesions appear alone. The literature presents few studies that propose a multidisciplinary approach (restorative and root coverage surgery procedures) to optimize the treatment of this combined lesion. The previously proposed approaches and materials have limitations and an optimal clinical protocol has not been established yet. Thus the aim of this study is to evaluate a novel multidisciplinary protocol with two resin composites and two different adhesive systems through a randomized clinical trial and laboratory studies. 120 combined lesions will be randomly assigned to one of the following groups: NP + TE (n = 30) - Partial restoration of cervical lesions with nanofilled composite and total-etch adhesive system and periodontal surgery for root coverage, NP + UA (n = 30) - partial restoration of cervical lesions with nanofilled composite and self-etching adhesive system and periodontal surgery for root coverage, MH + TE (n = 30) - partial restoration of cervical lesions with microhybrid composite and total-etch adhesive system and periodontal surgery for root coverage, MH + UA (n = 30) - partial restoration of cervical lesions with microhybrid composite and self-etching adhesive system and periodontal surgery for root coverage. Restorations will be assessed using the USPHS criteria after one week, six months and twelve months.

What is being measured

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

  1. Modified United States Public Health Service (USPHS) criteria

    USPHS criteria is based on the following ratings: Color compatibility, retention, marginal adaptation, anatomic form, surface texture, marginal discoloration, sensibility pre-operative and postoperative and the presence of secondary caries

    Measured: 1 year

Secondary outcomes (2)
  1. Aesthetics (Visual Analogue Acale - VAS)

    The esthetics of the treatment will be evaluated by patients´ point of view using the VAS scale

    Measured: 1 year

  2. Dentin Hypersensitivity (Visual Analogue Acale - VAS)

    The Dentin Hypersensitivity will be evaluated by patients´ point of view using the VAS scale

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing Periodontal surgery, Total Etch adhesive and Universal Adhesive in people with Dental Abrasion and Gingival Recession, run by Universidade Estadual Paulista Júlio de Mesquita Filho at 1 site 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 5 inclusion and 7 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: finished, as of the sponsor's last update on 13 Jun 2019. 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 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Modified United States Public Health Service (USPHS) criteria (time frame: 1 year). 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 NCT03215615, which also lists 1 linked publication.

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 13 Jun 2019; AzTrials last refreshed its copy on 6 Nov 2026.
