Carious Primary Molars

The goal of this clinical trial is to compare pain Perception, patient acceptability, and cavity preparation time between chemo-mechanical caries removal and Atraumatic restorative treatment Method in Primary Molars. The main questions it aims to answer: "Does chemo-mechanical caries removal show similar results compared to Atraumatic restorative treatment Method in terms of pain perception in Primary Molars?

This randomized controlled clinical trial aims to compare two restorative techniques for managing carious primary molars in children aged 6-9 years: the Hall Technique and conventional stainless-steel crown (SSC) placement. The study evaluates how each technique affects occlusal force distribution, mean bite force, and vertical dimension changes using the T-Scan digital occlusal analysis system. Additional outcomes include temporomandibular joint assessment, child discomfort levels, and parental satisfaction with treatment. Participants are allocated 1:1 to receive either the Hall Technique or conventional SSC restoration, and outcomes are measured at baseline, immediately after treatment, and at 2- and 4-week follow-ups. The study aims to determine whether the minimally invasive Hall Technique provides comparable occlusal function and patient-centered outcomes when compared to traditional SSC preparation methods.

Will Calcium-Enriched Mixture (CEM) cement pulpotomy have less postoperative pain and more clinical and radiographic success compared to Calcium Hydroxide/Iodoform (Metapex) pulpectomy when managing second primary molars with irreversible pulpitis?

The goal of this clinical trial is to evaluation of Zinc oxide-eugenol compared to Zinc oxide with Neem as obturating materials in primary mandibular molars pulpectomy for 5-7 Year-Old Children.The main question(s)it aim to answer : Could the clinical and radiographic success of a mixture of zinc oxide with Neem oil be comparable with Zinc oxide-eugenol paste in pulpectomy of primary mandibular molars?

This study aims to evaluate and compare the preparation time required for Bioflx crowns versus zirconia crowns on primary molars through a randomized clinical trial. • Primary Objective: To compare the preparation time required for Bioflex crowns and zirconia crowns on primary molars in pediatric patients. • Secondary Objectives: To evaluate the clinical performance of Bioflex crowns compared to zirconia crowns, including: Retention, Patient Satisfaction, Parental Satisfaction, Occlusal Wear and Gingival Health. the main question it aim to answer: Is there a significant difference in the preparation time required for Bioflx crowns compared to zirconia crowns in the primary molars of pediatric patients?

The goal of this clinical trial is to evaluate the Evaluation of Gingival Health and Bacterial Adhesion of Bioflx Crowns Compared to Zirconia Crowns on Primary Molars of Bioflx crowns compared to zirconia crowns in the restoration of primary molars. The main question\[s\] it aims to answer is there are the differences in bacterial adhesion and gingival health between bioflx and zirconia crowns The study will also assess the clinical performance of both types of crowns in terms of bacterial adhesion , child and parents satisfaction,as well as preparation time.
