Pulp Therapy and Zirconia Crown Restoration of Primary Molars with T-Scan Occlusal Analysis
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.
Study 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.

Inclusion Criteria:
* Children aged 6 to 9 years.
* Both boys and girls can participate.
* A pulp-treated primary molar (pulpotomy) that is healthy and shows no pain, no swelling, no mobility, and no radiographic problems (such as internal resorption or infection).
* The lower first permanent molar must be erupted.
* The child is cooperative during dental treatment (positive behavior on the Frankl scale).
* The child has no missing teeth.
* The child has a normal bite (normal overjet and overbite).
* The child is generally healthy with no systemic diseases, to ensure they can attend follow-ups.
Exclusion Criteria:
* Children with medical conditions or who are uncooperative during dental care.
* Children with parafunctional habits, such as teeth grinding (bruxism), thumb-sucking, or other habits that may affect bite-force measurements.
* Teeth that are close to falling out, have severe root resorption, or need extraction.
* Teeth with deep cavities below the gum line that prevent proper crown placement.
* Teeth that are mobile (Miller's Grade 2 or higher).
* Teeth that have had previous pulp therapy other than the included pulpotomy.
* Children who are unable to attend follow-up visits or whose parents do not agree to participate.
Primary outcome measure(s)
Mean Bite Force — Baseline (pre-operative), immediate post-operative, 2 weeks post-operative, 4 weeks post-operative Bite force will be measured using the T-Scan digital occlusal analysis system. Participants will bite on the sensor in a standardized position, and the system will record bite force as a percentage of total occlusal force distributed among teeth. This measure reflects functional adaptation of occlusion after crown placement.
