Occlusal Impact of Hall Crowns in Primary Molars

Turkey (Türkiye)60 participantsStarted 2025-09-15

Plain-language summary

Hall Technique is a non-invasive restorative approach for managing carious primary molars, increasingly used in pediatric dentistry due to its simplicity and patient tolerance. This study aims to evaluate and compare the occlusal changes that occur following Hall crown placement on different primary molar groups (maxillary first molar, maxillary second molar, mandibular first molar, mandibular second molar) using digital model analysis.

Inclusion Criteria: Inclusion Criteria for Participants * No skeletal or dental anomalies, * ASA (American Society of Anesthesiologists) physical status classification of I or II , * Frankl Behavior Rating Scale score of 3 or 4, * In the mixed dentition stage, * Fully erupted permanent first molars in occlusal contact at maximum intercuspation * No acute dental pain or need for emergency treatment, * Presence of at least two primary molars with carious lesions scored as 3, 4, or 5 according to the ICDAS (International Caries Detection and Assessment System), * Presence of an antagonist tooth for the molar planned to receive Hall Technique, * Provision of verbal and written informed consent by the participant and legal guardian after reading or listening to the consent form and fully understanding its content. Inclusion Criteria for Tooth Based on Clinical Examination: * No history of prolonged pain in response to thermal or chemical stimuli, or spontaneous pain suggestive of irreversible pulpitis, * No sensitivity to percussion or palpation, * Absence of both pathological and physiological mobility, * No signs of swelling, fistula, or discoloration, * Sufficient remaining tooth structure to retain a preformed stainless steel crown. Based on Radiographic Examination: * Radiolucent lesion associated with dental caries located within the outer one-third to two-thirds of the dentin, with a visible band of normal dentin between the lesion and the pulp, * At least two-thirds…

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.
