About this study

Official title: Biofilm Inhibition and Remineralizing Potential of Bioactive Restorative Materials: Two-Year Randomized Clinical Trial in Class I Cavities

The objectives of this study are to evaluate and compare the biofilm inhibition and re-mineralizing potential at tooth restoration interface and their 2-year clinical performance in class I cavities.The patients will be selected from the Outpatient clinic at Faculty of Dentistry, Mansoura University. Patients will be informed about the steps of the study, whom will approve, will sign a written consent form. The form and protocol will be approved by the Ethics Committee. Each patient should have 4 frank carious dentinal lesions (ICDAS score 4 or 5) in posterior teeth. A periapical radiograph will be performed to evaluate the extension of the carious lesion and to ensure that there is no radiolucency in the periapical or furcation area. The teeth have to be vital, not sensitive to percussion and/or spontaneous pain. The patients will be required to have complete and normal occlusion as well as good oral hygiene.

Read the detailed description

This study will be intended to evaluate and compare the biofilm inhibition and re-mineralizing potential at tooth restoration interface and their 2-year clinical performance in class I cavities.

Null hypothesis This study will be designed to test the null hypothesis that there will be no significant difference in neither biofilm inhibition nor remineralizing potential at tooth-restoration interface of the used tested materials. Also, that there will be no significant difference in the 2-year clinical outcomes of the bioactive restorative materials in class I cavities.

Sample size calculation was based on clinical performance according to FDI criteria between different bioactive restorative materials that was retrieved from previous research.19 Using G power program version 3.1.9.7 to calculate sample size, using 2-tailed test, α error =0.05 and power = 80%, the total calculated sample size will be 30 cases at least in each group Patient selection The patients will be selected from the Outpatient clinic at Faculty of Dentistry, Mansoura University. Patients will be informed about the steps of the study, whom will approve, will sign a written consent form. The form and protocol will be approved by the Ethics Committee. Each patient should have 4 frank carious dentinal lesions (ICDAS score 4 or 5) in posterior teeth. A periapical radiograph will be performed to evaluate the extension of the carious lesion and to ensure that there is no radiolucency in the periapical or furcation area. The teeth have to be vital, not sensitive to percussion and/or spontaneous pain. The patients will be required to have complete and normal occlusion as well as good oral hygiene.

Study Design:

The total number of patients will be 30 patients. Each patient will receive restorative materials studied in this investigation.

Clinical procedures All restorations will be done by a single experienced operator and with proper magnification aids. The restorative procedures will be performed under local anesthesia and rubber dam isolation. Cavity preparations for resin composite restoration will be prepared using high speed handpiece.

Evaluation procedures All restorations will be clinically evaluated immediately after finishing and polishing (baseline), 6 months, 12 months, 18 months and finally after 24 months by two independent examiners. If any restoration failed, repair or replacement of the restoration will be considered.

  • application of beautiful blukfill II shofu compositeProcedure or surgery

    Operative procedures were performed under local anesthesia and rubber dam isolation. Cavities were prepared using round diamond points (for enamel) and straight fissure and round carbide burs (for cutting in dentin) in a high-speed handpiece. Remaining infected carious dentin was excavated using a hand excavator. Cavities were finished using fine grit yellow-coded tapered diamond stones. 37% phosphoric acid gel was applied for 15 seconds on enamel margins, rinsed with water for 15 seconds and cavities were air-dried with Teflon protection on dentin. Self-etching universal adhesive was actively rubbed on cavity surfaces. Light curing was performed for 20 seconds. In cavities without a liner, beautiful bluk fill II composite were placed in bulk (maximum 4mm thickness layer) and cured for 40 seconds, Occlusal adjustments were performed.

What is being measured

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

  1. Postoperative hypersensitivity/pulp status

    Postoperative hypersensitivity/pulp status.The postoperative hypersensitivity/pulp status will be assessed based on the updated FDI criteria

    • Intensity was assessed with Visual Analogue Scale. Postoperative sensitivity was evaluated by blowing a stream of compressed air for 3 seconds at a distance of 2-3 cm from the restoration. -Vitality was tested with application of cold (dry ice) and compared the reaction with the adjacent vital teeth . This parameter is evaluated by scoring the pain experienced during chewing and/or with cold or warm food items, as reported by the patient. The criteria consist of five scores: scores 1-3 indicate success, score 4 indicates the need for restoration repair, and score 5 indicates the need for restoration replacement.

    Measured: Two years after restoration

  2. Marginal adaptation

    The marginal adaptation will be evaluated through visual examination using a - A magnifying aid (loupe 4.5 x) was used for evaluation. Two special probes with different blunt tips (150 and 250 μm). This assessment will be conducted according to the updated FDI criteria. The criteria consist of five scores: scores 1- 3 indicate success, score 4 indicates the need for restoration repair, and score 5 indicates the need for restoration replacement.

    Measured: Two years after restoration]

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 3 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 4 Jun 2025. 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 Egypt. 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?

Postoperative hypersensitivity/pulp status (time frame: Two years after restoration). The study lists 2 primary outcomes in all. 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 4 Jun 2025.
