Time of Treatment in HALL Technique Vs ART

The goal of this clinical trial is to assess the time of treatment of Hall Technique versus Atraumatic Restorative Technique in the management of carious primary molars. The main questions it aims to answer are: * Does the Hall Technique provide a faster and pain-free treatment compared to ART? * How do the outcomes of both techniques impact children's acceptance and behavior? Researchers will compare the Hall Technique, which uses preformed metal crowns without caries removal, to Atraumatic Restorative Treatment, which uses hand instruments to selectively remove carious tissue. Participants will: * Receive treatment using either the Hall Technique or ART in a single session. * Attend follow-up visits to monitor the effectiveness and acceptance of the treatment. * Complete assessments on their experience and comfort during and after the procedure.
