Hall Technique in Pediatric Dentistry Across Arab League Countries: Clinical Success, Parental Acceptance, and Pediatric Dentists Adoption – A Systematic Review and Meta-analysis

eview question / Objective Among pediatric patients in Arab League countries: 1.What are the clinical success rates of preformed metal crowns placed using the Hall Technique for carious primary molars?2. What is the level of parental acceptance and satisfaction with the Hall Technique?3. What is the extent of knowledge, attitude, and adoption of the Hall Technique among pediatric dentists?Rationale Background & Rationale Dental caries in primary teeth is highly prevalent in many Arab League countries, and access to childfriendly, minimally invasive treatments is a major public health need.The Hall Technique (HT) is a minimally invasive method for managing carious primary molars using preformed metal crowns without caries removal, tooth preparation, or local anaesthesia.Evidence from international studies suggests that the Hall Technique achieves high clinical success, with good acceptance by children and parents, and increasing adoption by pediatric dentists.However, practice patterns, parental expectations, c u l t u r a l f a c t o r s , a n d h e a l t h c a re s y s t e m organization differ across Arab League countries, w h i c h m a y i n fl u e n c e c l i n i c a l o u t c o m e s , satisfaction, and uptake of the technique.The Arab League countries represent a diverse region with varying healthcare infrastructure, dental training standards, and clinical practice patterns.Understanding the adoption, effectiveness, and acceptability of the Hall technique across these nations is essential for informing evidence-based clinical practice and policy development.Several studies from the Arab region (clinical trials, observational cohorts, and questionnaire-based surveys) have investigated:• Clinical success/failure rates of Hall Technique crowns in children.• Parental acceptance and satisfaction.• Knowledge, attitudes, and adoption of the Hall Technique among pediatric dentists.To date, no comprehensive systematic review and meta-analysis has synthesized this evidence specifically for Arab League countries, nor
