Digital Occlusal Analysis and Bite Force Evaluation of Hall Technique Vs Stainless-Steel Crowns as Conventional Restoration of Carious Primary Molars Using T-scan: A Randomized Clinical Trial
This randomized controlled clinical trial aims to compare two restorative techniques for managing carious primary molars in children aged 6-9 years: the Hall Technique and conventional stainless-steel crown (SSC) placement. The study evaluates how each technique affects occlusal force distribution, mean bite force, and vertical dimension changes using the T-Scan digital occlusal analysis system. Additional outcomes include temporomandibular joint assessment, child discomfort levels, and parental satisfaction with treatment. Participants are allocated 1:1 to receive either the Hall Technique or conventional SSC restoration, and outcomes are measured at baseline, immediately after treatment, and at 2- and 4-week follow-ups. The study aims to determine whether the minimally invasive Hall Technique provides comparable occlusal function and patient-centered outcomes when compared to traditional SSC preparation methods.

- Stainless-steel Crown
Interventions
- Hall Technique Stainless Steel Crown Placement

Primary outcomes

Occlusal evaluation for bite force will be done using T-Scan III. Changes in bite force at different periods will be assessed using a standardized T-Scan III Software. The obtained bite force will be recorded in percentage concerning the crowned tooth, opposing tooth, right and left side of the arch, during preoperative, postoperative and follow up periods after 2 and 4 weeks. The maximum intercuspal position (MIP) will be measured by changes in the bite force %.
