Comparative evaluation of tensile bond strength of composite resin to etched and unetched glass ionomer cement-An in vitro study
Bibliographic record
Abstract
Background: Acid etching of Glass Ionomer liner to increase bond strength between Glass Ionomer cement and composite resin. Aims & Objectives: To compare the tensile bond strength of Glass Ionomer cement to composite resin with and without etching the cement. Materials and Method: Ten pairs of metal cylinders (mould) were prepared for this study. Four groups based on hybrid and micro filled type of composite resin in 10 pairs each. In each type, 10 Glass Ionomer specimens were treated with acid etching and 10 were not treated. Results: The results showed no significant differences between any of four groups, showing that application of 37% phosphoric acid did not result in significant bond strength between Glass Ionomer cement and composite resin. Conclusion: Both the types of composite resin did not show any significant difference in bond strength to Glass Ionomer cement, whether etched or unetched.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
