Abstract

fetched live from OpenAlex

Aim and objective: This study aimed to evaluate the color stability, translucency, and wettability of a lithium disilicate dental ceramic.Materials and methods: Forty specimens (6 × 1 mm) of lithium disilicate dental ceramic were fabricated.Initial color and translucency readings were measured using a spectrophotometer.Then, the specimens were randomly separated into four groups (n = 10), according to the different types of surface treatment (control: control group; HF + S: hydrofluoric acid gel and silane; Al + HF + S: Al 2 O 3 , hydrofluoric acid gel, and silane; Al + S: Al 2 O 3 and silane) and new color and translucency readings were done.The wettability was analyzed using the sessile drop method in all specimens, and the results were statistically analyzed using one-way ANOVA and the Tukey test (p < 0.05). Results:The results showed higher color and translucency changes to the groups treated (HF + S, Al + HF + S, and Al + S), different (p < 0.05) from the control group, and without significance between them.All groups demonstrated different wettability (p < 0.05), lower for the control group.Conclusion: It is possible to conclude that the surface treatment can influence the color, translucency, and wettability of lithium disilicate dental ceramics.

Not 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.
