What was done
The authors conducted a narrative review evaluating the evidence base and cognitive biases behind nine biomimetic restorative dentistry (BRD) protocols compared to traditional adhesive techniques. They searched PubMed, Embase, and Cochrane Library CENTRAL for randomized clinical trials and systematic reviews examining these interventions.
What was found
No numerical results, effect sizes, or quantitative data were reported in the abstract. Qualitatively, the review reported: 1. Caries-detecting dyes cause excessive removal of dentin. 2. Aluminum oxide air abrasion contributes to overtreatment and potential occupational health hazards. 3. Beveling posterior enamel causes unnecessary tissue loss without clinical evidence of outperforming butt-joint preparations. 4. Chlorhexidine deactivation of matrix metalloproteinases lacks clinical evidence of improving restoration longevity. 5. Supposed gold-standard adhesive systems perform no better than other high-performing adhesive systems. 6. Immediate dentin sealing and resin coating result in similar post-operative sensitivity and longevity for indirect restorations compared to delayed dentin sealing. 7. Deep margin elevation is a viable alternative for subgingival occlusoproximal cavity margins. 8. Time-delayed decoupling lacks scientific evidence. 9. Fiber inserts placed on the pulpal floor or axial wall offer no benefit over conventional alternatives.
Why it matters
This review highlights that several widely promoted biomimetic restorative protocols rely on anecdotal claims and mechanistic assumptions rather than clinical trial evidence of improved restoration survival.
Limits
As a narrative review, the abstract does not report explicit systematic inclusion criteria, risk-of-bias assessments, or quantitative data. The number of reviewed primary studies and patient characteristics were not reported in the abstract. Longitudinal clinical trial evidence remains lacking for several assessed techniques.
