Evidence¶

Chien 2025¶

Chien, P.Y.‐H., Hosseinpour, S., Peters, O.A. & Peters, C.I. (2025). Outcomes of root canal treatment performed by undergraduate students: A systematic review and meta‐analysis. International Endodontic Journal. https://doi.org/10.1111/iej.14246

q3 · i? · quant-synthesis · r2

Weighted pooled success rates from the same three‐study random‐effects meta‐analysis of student‐performed treatment (294 roots with lesions, 477 without, per Table 3). The review reports "86.8% vs. 56.3%"; no standardized effect size is printed.

"Similarly, teeth without preoperative periapical lesions demonstrated higher success rates compared to those with and without preoperative radiolucencies (86.8% vs. 56.3%)."

Discussion¶

Related Claims¶

• Root canal treatment by undergraduate students succeeds more often in teeth with vital pulps (87.8%) than necrotic pulps (65.6%) — related
• Pooled risk difference across 11 student‐clinic studies is 0.43 but with considerable heterogeneity (I² = 93%) — a broader claim this one bears on
• Anterior and pre‐molar teeth show higher student treatment success rates (82.2% and 79.4%) than molars (68.7%) — related
