Posterior composite restorations: Theoretical and practical teaching of undergraduate students in Serbia and abroad
Bibliographic record
Abstract
Introduction. Due to the educational process inertia based on textbook literature, teaching of undergraduate students in dental schools is often behind modern practice. From the aspect of minimally invasive dentistry, composites are materials of choice for the reconstruction of most lesions in posterior teeth. The objective of the study was to systematize data about theoretical and practical teaching of undergraduate students regarding the application of posterior resin composites in the world?s dental schools and compare it with the data obtained from the School of Dental Medicine, University of Belgrade. Material and Methods. MEDLINE database was searched for articles based on keywords dental education and posterior composites. Only articles published in the last five years and those which used the same questionnaire were included in the study. Results. Data were analyzed for the dental schools from the UK and Ireland, Spain, Japan, United States and Canada. Increased theoretical and practical teaching of students regarding posterior composites is noted in most schools. The dominant contraindication for using resin composite is allergy to its ingredients. Rubber dam is the most common method of providing aseptic conditions and dry field in the world, whereas in our school it is used in negligible number of cases. In a number of schools, metal matrices and wooden wedges are recommended for the proximal cavity restoration. Glass-ionomer cement is commonly used as a liner. Polishing and finishing of restorations is performed in the same session in 90-100% of the schools except in Japan, where it is carried out after 24 hours. Conclusion. Theoretical and practical teaching of posterior composite restorations is increasing in the world?s dental centers. It is necessary to harmonize teaching in our school with international trends in the use of rubber dam, certain aspects of cavity design and protocols for the treatment of deep caries lesions.

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.
