About this study

Official title: Clinical Performance of MTA Cavity Lining in the Treatment of Deep Caries Lesions: A 4- Year Randomized Controlled Clinical Trial

Aim of this clinical study is to compare the clinical success of two lining materials regarding the maintenance of pulp vitality in the treatment of deep caries lesions over 4- years.

A hundred permanent premolar and molars with deep caries lesions without pulp involvement (aged between 18 and 30 years) in 73 patients were randomly divided into the following groups: calcium hydroxide cement (Ca(OH)2) (Dycal, Dentsply/Caulk, Dentsply International Inc, Milford, DE, USA) group and mineral trioxide aggregate (MTA) (Dentsplay, Tulsa Dental, Johnson city, USA) group. Final restoration with a resin-based composite (Gradia Direct Posterior, GC, Tokyo, Japan) in a single session was performed. The following-up period was 6-, 12-, 24-, 36- and 48-months. Two calibrated examiners performed the clinical examination of the pulpal symptoms

Aim of this clinical study is to compare the clinical outcomes of mineral trioxide aggregate (MTA) cavity lining with calcium hydroxide (Ca(OH)2) regarding the maintenance of pulp vitality in the treatment of deep caries lesions over 4- years.

Materials and Methods: A hundred permanent premolar and molars with deep caries lesions without pulp involvement (aged between 18 and 30 years) in 73 patients were randomly divided into the following groups: calcium hydroxide cement (Ca(OH)2) (Dycal, Dentsply/Caulk, Dentsply International Inc, Milford, DE, USA) group and mineral trioxide aggregate (MTA) (Dentsplay, Tulsa Dental, Johnson city, USA) group. Final restoration with a resin-based composite (Gradia Direct Posterior, GC, Tokyo, Japan) in a single session was performed. The following-up period was 6-, 12-, 24-, 36- and 48-months. Two calibrated examiners performed the clinical examination of the pulpal symptoms. The data will be analyzed with Pearson chi-square, Fisher exact and logrank statistics tests (p < 0.05). The Kaplan-Meier survival analysis will be conducted to reveal the survival rate.

What is being measured

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

  1. Evaluating of clinical success of restorations

    The treatment consequence was judged as "clinically successful" when the following criteria were met: positive response to electric pulp testing, negative response to cold stimuli by air-water shrinkage, no general pain, normal response to tactile tests or triggered pain not lingering, no evidence of abscess, sinus tract and no abnormal tooth mobility. These teeth were considered to be "clinically healthy" and the treatment was successful.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing MTA and Dycal in people with Mineral Trioxide Aggregate and Calcium Hydroxide, run by Hacettepe University.

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 3 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 16 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

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?

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?

Evaluating of clinical success of restorations (time frame: 6 months). 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 16 Jul 2019.
