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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
No signs or symptoms of irreversible pulpitis
Molars with carious lesions affecting two or more surfaces
Permanent first molars with developmental defects

Crossover
Treatments tested in this trial
Stainless steel crown placement using Hall Technique
DevicePreformed stainless steel crowns are placed on permanent first molars without local anesthesia, caries removal, or tooth preparation. Orthodontic separators are used as needed, and crowns are cemented with glass ionomer cement
Stainless steel crown placement using conventional method
DevicePreformed stainless steel crowns are placed after administering local anesthesia and performing standard tooth preparation, including occlusal and proximal reduction. Crowns are cemented with glass ionomer cement.

Trial outcomes
Primary outcomes
1
Clinical and Radiographic Success
Clinical and Radiographic Success Definition: Absence of clinical symptoms (pain, swelling, mobility) and absence of radiographic signs of pathology (periapical radiolucency, internal/external resorption).
Time frame
Baseline, 1 month, 3 months, and 6 monthsSecondary outcomes

- Marginal Fit and Adaptation - Changes in Occlusion ( Overbite) - Patient Satisfaction (Likert Scale)
Secondary Outcome Measures Marginal Fit and Adaptation of Crown Definition: Clinical assessment of marginal adaptation (good, acceptable, poor). Time Frame: Post-treatment, 1 month, 3 months, and 6 months Changes in Occlusion (Overbite) Definition: Measurement of changes in vertical dimension of occlusion and overbite using clinical examination. Time Frame: Post-treatment, 1 month, 3 months, and 6 months Patient Satisfaction (Five-Point Likert Scale) Definition: Patient-reported satisfaction using a 5-point Likert scale (1 = very dissatisfied, 5 = very satisfied). Higher scores indicate greater satisfaction. Time Frame: Immediately post-treatment, 1 month, 3 months, and 6 months
