q3 i? Success rates were greater for anterior and pre‐molar teeth than for molars in student‐performed root canal treatment. → Chien 2025

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 · r1

Weighted pooled success rates by tooth type from the three‐study meta‐analysis (351 molars, 216 pre‐molars, 202 anterior teeth). The review attributes the gradient to "the complexity of molar anatomy"; no standardized effect size is printed.

"Anterior and pre‐molar teeth showed greater success rates than molars (82.2% and 79.4% vs. 68.7%), which may reflect the complexity of molar anatomy."

Discussion¶

Related Claims¶

• Student root canal treatment success is lower in teeth with preoperative periapical radiolucencies (56.3%) than without (86.8%) — 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
• Only 4 of 11 studies (36.4%) of student root canal treatment had low risk of bias — related
• Student clinic success rates do not differ significantly from those reported for experienced clinicians and residents — related
• Root canal treatment by undergraduate students succeeds more often in teeth with vital pulps (87.8%) than necrotic pulps (65.6%) — related
