Hall Technique vs Conventional Crown Restoration in Permanent Molars: Split-Mouth Trial in Children
Syria10 participantsStarted 2025-11
Plain-language summary
The aim of this study is to compare the clinical and radiographic success of stainless steel crowns placed using the Hall Technique versus the conventional method in the restoration of permanent first molars in children, and to evaluate their effects on occlusal relationships, crown adaptation, and patient satisfaction.
Study Outcomes The primary outcome of this study was to evaluate the clinical and radiographic success of stainless steel crowns placed on permanent first molars using the Hall Technique in comparison to the conventional crown placement method. The secondary outcomes included assessment of the marginal fit and adaptation of preformed crowns using both techniques, analysis of changes in occlusal relationships-specifically the vertical dimension of occlusion and overbite-and evaluation of patient satisfaction. Patient satisfaction was measured using a five-point Likert scale at multiple time points: immediately post-treatment, and at one, three, and six months.

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?

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?
