Summary

The goal of this observational study is to evaluate the adaptation of occlusion and bite force after zirconia crown restoration in children with pulp-treated primary molars. The main questions it aims to answer are: How does occlusion adapt after placement of zirconia crowns? Does bite force change following crown restoration? Participants will: Undergo routine pulp treatment and restoration of primary molars with zirconia crowns. Have bite force and occlusal contacts measured using the T-Scan digital occlusal analysis system before and after crown placement.

Detailed description

his observational before-and-after study is designed to evaluate occlusal adaptation and functional outcomes in children undergoing pulp treatment and restoration of primary molars with zirconia crowns. The study employs the T-Scan Novus digital occlusal analysis system to objectively measure bite force distribution and occlusal contact patterns. After informed consent is obtained from parents or legal guardians, baseline occlusal measurements will be collected using the T-Scan system prior to crown placement. Standard pulp therapy and restoration procedures will be performed according to pediatric dental protocols. Prefabricated zirconia crowns will be selected and fitted, with occlusal adjustments performed as needed to ensure proper seating and contact. Participants will be scheduled for follow-up visits at 2 weeks and 4 weeks post-restoration, during which occlusal measurements will be repeated using the T-Scan system. These follow-ups are designed to track the progressive adaptation of occlusion and detect any functional changes following crown placement. Additional technical considerations include: Calibration of the T-Scan system prior to each measurement session. Standardized patient positioning during measurements to ensure reproducibility. Recording of bite force in a controlled environment, minimizing variables such as head posture and tongue position. Monitoring of crown integrity and fit during follow-up visits. This study will provide detailed insight into the functional adaptation of primary molars after zirconia crown restoration, including occlusal contact patterns and bite force distribution, contributing to evidence-based recommendations for pediatric restorative dentistry.

Interventions

Type	Name	Description
PROCEDURE	Pulp Therapy and Zirconia Crown Restoration of Primary Molars with T-Scan Occlusal Analysis	Participants will receive pulp therapy followed by restoration of primary molars with prefabricated zirconia crowns according to standard pediatric dental protocols. Occlusal function and bite force will be assessed using the T-Scan digital occlusal analysis system at baseline, and at 2 and 4 weeks post-restoration. This intervention combines a therapeutic dental procedure with objective, instrumented measurement of occlusal adaptation, allowing participants to act as their own controls. Follow-up visits will monitor crown fit, occlusal contacts, and bite force changes over time.
