Effects on Alkaline Phosphatase Level in Crevicular Fluid Produced by Rapid Palatal Expansion with Hyrax Expander
Bibliographic record
Abstract
Introduction: Rapid maxillary expansion (RME) is a dramatic and preferred procedure having a history of over 100 years. When a transverse maxillary Arch is diagnosed it is corrected by doing RME. Although several studies have been done in last four decades on gingival crevicular fluid, no data have been reported on the repeatability of gingival crevicular fluid collection and then following its quantification procedure. The objectives of this study were to examine the changes in alkaline phosphatase (ALP) activities in gingival crevicular fluid (GCF) during rapid palatal expansion and in retention period by hyrax, and to explore the relationship between these changes and periodontal tissue remodeling. Methodology: Seventeen patients with age between 9-14 years were selected according to inclusion and exclusion criteria. Periodontal parameters, including probing depth, were recorded at 3 months after RME. Furthermore, the GCF ALP activity was measured at the buccal and palatal sites. Results: Periodontal parameters were generally similar between the Testing and Control sites during the study, with the exception that probing depth underwent a slight increase at the Testing sites. It was observed that at baseline, the GCF ALP activity was similar between the buccal and Control sites; however, at 3 months of retention period a significantly greater enzymatic activity was seen at the Testing sites.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
