Evaluating Occlusal Changes After Hall Technique Crowns on Different Primary Molars in Children Aged 7 to 10

What this Trial Is About

Researchers are evaluating the occlusal changes that happen after placing Hall crowns on different primary molar groups in children aged 7 to 10 years. The study aims to compare these changes among maxillary and mandibular first and second primary molars and to understand how the molar group and jaw location affect occlusal adaptation using digital model analysis. This study is a randomized controlled clinical trial conducted at a pediatric dentistry clinic. In this study, 60 children with at least two carious primary molars will receive a Hall crown on one randomly selected molar without local anesthesia or tooth preparation. The crown is a preformed stainless-steel crown cemented with glass ionomer cement. Participants are divided into four groups based on the treated molar maxillary first or second molar and mandibular first or second molar. Digital intraoral scans will be taken before crown placement, immediately after, at two weeks, and at one month to assess occlusal changes. Participants will have digital scans and bite registrations taken at four time points to measure changes in tooth and cusp tip positions, occlusal vertical dimensions, and contact areas. Statistical analysis will compare these measurements among groups over time. All other necessary dental treatments will be completed before crown placement to avoid interference. The total participation lasts about one month with follow-up scans to monitor occlusal adaptation.
