The goal of this clinical trial is to learn if prefabricated zirconia crowns (PZCs) improve gingival health compared to stainless steel crowns (SSCs) in primary molars of young children. It will also learn about plaque accumulation and parental satisfaction with the crowns. The main questions it aims to answer are: 1. Do PZCs lead to better gingival health than SSCs over time? 2. Do PZCs reduce plaque accumulation compared to SSCs? 3. Do parents report higher satisfaction with PZCs versus SSCs? Researchers will compare PZCs to SSCs in a split-mouth design (each child receives one of each crown type on contralateral molars) to see if PZCs provide superior gingival health, plaque control, and satisfaction. Participants will: 1. Receive PZCs on one primary molar and SSCs on the contralateral molar after tooth preparation 2. Attend follow-up visits at 12, 24, and 36 months for gingival health and plaque assessments 3. Complete parental satisfaction surveys at each follow-up visit
