Summary
This study analyzed cement types under pediatric stainless steel crowns on primary molars. Stiffer cements increased tooth stress but reduced crown stress, with minimal bone impact.
Area of Science:
- Pediatric Dentistry
- Biomaterials Science
- Dental Mechanics
Background:
- Stainless steel crowns (SSCs) are common for primary molars.
- Cement selection influences restoration performance.
- Understanding cement effects on stress distribution is crucial for pediatric dental restorations.
Purpose of the Study:
- To evaluate the impact of four different cement types on stress distribution under pediatric SSCs.
- To analyze stress and deformation in the mandibular second primary molar using 3D finite element analysis.
Main Methods:
- A 3D finite element model of a pediatric mandibular molar was created.
- Four cement types (zinc phosphate, glass ionomer, resin-modified glass ionomer, resin) were simulated.
- Simulations included loads of 330 N at vertical, 45° oblique, and lateral angulations.
Main Results:
- Stress and deformation patterns were similar across cement types, but values varied.
- All simulated stresses and deformations remained within acceptable physiological ranges.
- Increasing cement stiffness elevated stress in tooth structure while decreasing it in the crown.
Conclusions:
- Cement type significantly affects stress distribution within the tooth and crown.
- Stiffer cements may increase stress on the tooth structure but reduce stress on the crown.
- The surrounding bone tissue showed minimal sensitivity to the type of cement used.
