简要总结

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.

详细描述

Detailed Description of the Study

This clinical study is designed to evaluate and compare the clinical and radiographic effectiveness of the Hall Technique and the conventional crown placement method for restoring permanent first molars in children using a split-mouth design. The study will be conducted at the Department of Pediatric Dentistry, Faculty of Dentistry, Tishreen University.

A total of 10 pediatric patients will be recruited according to specific inclusion and exclusion criteria. Each child will present with at least two eligible permanent first molars requiring full coronal restoration with stainless steel crowns. In the split-mouth design, each child will serve as their own control: one molar will be treated using the Hall Technique (HT), and the contralateral molar will be restored using the conventional method. The allocation of which technique will be applied to which side will be randomized for each patient to minimize bias.

Inclusion criteria will include:

  • Permanent first molars with carious lesions affecting two or more surfaces or presenting Molar Incisor Hypomineralization (MIH).
  • Absence of clinical signs or symptoms of irreversible pulpitis.
  • Radiographic confirmation of an intact dentin layer and absence of internal or external root resorption or periapical pathology.

研究组 & 干预措施

Conventional Crown Preparation

Active Comparator

Permanent first molars are restored using the conventional method. Local anesthesia is administered, and the tooth is prepared with occlusal and proximal reduction before placement and cementation of a stainless steel crown using glass ionomer cement.

干预措施: Stainless steel crown placement using conventional method (Device)

Hall Technique

Experimental

Permanent first molars are restored using the Hall Technique. No local anesthesia, caries removal, or tooth preparation is performed. Orthodontic separators are placed if needed, followed by stainless steel crown (SSC) cementation using glass ionomer cement.

干预措施: Stainless steel crown placement using Hall Technique (Device)
