What the trial is, and whether it could suit you
Hall Technique is a non-invasive restorative approach for managing carious primary molars, increasingly used in pediatric dentistry due to its simplicity and patient tolerance. This study aims to evaluate and compare the occlusal changes that occur following Hall crown placement on different primary molar groups (maxillary first molar, maxillary second molar, mandibular first molar, mandibular second molar) using digital model analysis.
