About this trial
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.
