Purpose:
This study aimed to evaluate and compare occlusal adaptation and bite force distribution following the placement of stainless steel crowns (SSCs) and BioFlx crowns in children aged 4-8 years using the T-scan system.
Materials And Methods:
A randomized controlled clinical trial was conducted on 50 children requiring pulpectomy and crown restoration in primary molars. The participants were randomly assigned to receive either SSCs (n = 25) or BioFlx crowns (n = 25). Occlusal contacts and bite force parameters were recorded at three intervals: baseline (precementation), immediately postcementation, and at 2 weeks postplacement using the T-scan system. Statistical analysis was carried out using Friedman's test, Mann-Whitney U test, Cochran's Q test, and McNemar's test. A p-value < 0.05 was considered statistically significant.
Results:
Both crown types initially disturbed occlusal equilibrium and bite force distribution immediately after placement. At the 2-week follow-up, the BioFlx group demonstrated significantly better occlusal adaptation, with a quicker return to baseline bite force values and fewer persistent premature contacts compared to the SSC group (p < 0.05). Older children (>7 years) showed faster occlusal adaptation in both groups, especially in the BioFlx group.
Conclusion:
BioFlx crowns provided superior short-term occlusal adaptation and faster normalization of bite force distribution when compared to SSCs. Their flexibility and biocompatibility may contribute to enhanced patient comfort and rapid occlusal integration. The T-scan system served as a reliable tool for objectively assessing occlusal changes in pediatric restorative procedures.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
01:09Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
