Comparison of the Treatment Outcomes of the Conventional Stainless Steel Crown Restorations and the Hall Technique in the Treatment of Carious Primary Molars

Vietnam100 participantsStarted 2024-09-04

Plain-language summary

Stainless steel crowns have shown high success in restoring carious primary molars over a longer period of time than conventional restorations. This study aims to evaluate the treatment effectiveness of conventional SSCs restoration and Hall technique in treating carious primary molars

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion criteria

. Agree and voluntarily participate in the research (with the patient's parent/guardian consent for participation)
. Children have a primary molar with at least 2 carious lesions corresponding to International Caries Detection and Assessment System (ICDAS) scores 4 or at least 1 carious lesion corresponding to ICDAS scores 5 and 6.

Exclusion criteria

. Children with systemic diseases such as immunodeficiency, cardiovascular disease, or bleeding disorders.
. Children are allergic to nickel and resin.
. Children unable to return for recall visits.
. Primary molar has signs of pulpal/periapical diseases (irreversible pulpitis, pulp necrosis, loosening, fistula, or abscess).

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?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
