Effect of Sucrose as a Gustatory Stimulus on the Flow Rates of Parotid and Whole Saliva
Bibliographic record
Abstract
This study, on 12 young adults, was designed to determine the relationship between the sucrose concentration (0–80%) in the mouth and the flow rates of both whole and parotid saliva. In addition, the peak flow rate of parotid saliva was determined and the time interval between sucrose ingestion and achievement of maximum flow rate (DELAY), since these parameters were identified as determinants of oral clearance of sugar in a recent theoretical study of that process (Caries Res. 17:321–334, 1983). The mean ( ± SD) value of DELAY was 6.5 ± 2.1 s, which was independent of sucrose concentration. The peak flow rate was maintained only for a few seconds and then declined to a level linearly related to the sucrose concentration. However, even with 80% sucrose, mean flow rates for parotid and whole saliva, over the initial 30 s of stimulation, were only 0.39 ± 0.10 ml/min/gland and 3.8 ± 0.51 ml/min, respectively, with peak parotid flow rates being about double the mean values. To promote oral sugar clearance, it is desirable that dietary sources of sucrose be consumed only in association with foodstuffs having strong stimulatory effects on salivary flow.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
