Comparative Evaluation of Clinical Performance of Bulk-Fill Composites With Incrementally Layered Conventional Composites
Pakistan50 participantsStarted 2021-07-18
Plain-language summary
This study aimed to compare the clinical effectiveness of bulk-fill composites with conventionally layered incremental composites in Class I cavities using modified USPHS criteria. Fifty patients were selected based on sample size calculations. Each patient received two restorations, one from each group. Group I received incremental layering composite restorations, while Group II received bulk-fill composite restorations. Group I restorations were placed on the right side, and Group II restorations were placed on the left side. A single trained operator placed all restorations. After one year, the restorations were evaluated using modified USPHS criteria. Periapical radiographs were taken, and postoperative sensitivity was assessed using cold testing (ethyl chloride spray), with pain responses recorded using the Visual Analogue Scale.

Eligibility Criteria
Inclusion Criteria:
Patients aged 15 to 50 years, of either gender. Visiting Fatima Jinnah Dental College and Hospital OPD. Vital first and second molar teeth with Class I cavities, 3-4 mm in depth.
Exclusion Criteria:
Patients with xerostomia or bruxism (assessed via medical history). Teeth with irreversible pulpitis or necrotic pulps. Previously restored or periodontally compromised teeth.
Confounding Variables:
Confounding factors like xerostomia and bruxism were excluded. Factors like smoking and soft drink consumption were considered during analysis.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
