Abstract
OBJECTIVE: A systematic review and meta-analysis of the literature was carried out assessing the success and survival rate of anterior restorations used in localised wear cases. This also included assessment of posterior teeth re-establishing occlusal contact following use of the Dahl approach. DATA SOURCES: Two large databases; Medline via OVID, and Scopus were used to identify existing literature. The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and Meta-analyses guidelines and used the PIO framework [1]. Grey literature was also searched. STUDY SELECTION: Publications written in English were included between Jan 1970 and Nov 2020. POPULATION: participants with localised anterior tooth loss. INTERVENTION: anterior composite restorations. OUTCOME: success and survival rates of the composite restorations. Six cohort studies were included in the final analysis, with three prospective and three retrospective. These studies evaluated the success and survival rates of direct and indirect composite restorations, with a follow-up period ranging from 5 months to 10 years, which took place between 2000 to 2016. DATA EXTRACTION AND SYNTHESIS: Extracted data included: author(s) and year, study type, number and age of participants, number of restorations, location for intervention, type of intervention (direct vs indirect), type of composite, increase in OVD (amount of increase and period to re-establish posterior occlusion), follow up period, definition of failure, number of failed restorations, assessment of intervention and longevity/survival rate. Risk of bias in individual studies was assessed using The Newcastle Ottawa quality assessment scale (NOS) for cohort studies. Outcome measures were standardised as success or survival: Success - restoration assigned category A on the modified US Public Health Service (USPHS) criteria. Survival - restoration assigned category A or B on the modified USPHS criteria. The restoration was considered a failure if any other grades were allocated on the modified USPHS criteria. Results were visualised using forest plots. Heterogeneity between studies was measured by I-squared statistic. Sensitivity analysis was performed for each outcome. RESULTS: = 98%). Heterogeneity was generally considered high due to large variations in study design, sample size, type of intervention, and follow-up period. The success of the anterior composite Dahl approach in re-establishing posterior occlusion was reported at 85% (95% CI, 73%-94%), which took between 1.5 and 25.4 months. CONCLUSIONS: Anterior composite restorations had a high success rate over a period of 2-10 years in patients affected by localised tooth wear, which was higher over a 2-7 year interval. Although, the overall survival rates were considerably lower when accounting for minor and major types of restoration failure. This review supported continued use of anterior composites for restoring worn teeth, which had good short-medium term longevity. However, these conclusions should be interpreted with caution considering the quality of evidence, the heterogeneity of the studies and the limited number of studies included.

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 it
