Vegetarian Diet and the Mechanics of Root Canal Dentin: Surface Hardness, Scanning Electron Microscopy-quantified Tubule Irregularity, and Diametral Tensile Strength

Why it matters for dental
Endodontists and restorative dentists should note that vegetarian diets may alter root-canal dentin biomechanics—surface hardness, tubule regularity, and tensile strength—potentially influencing long-term outcomes of root-canal therapy and post-and-core restorations.
Key points
- Study in JOE (Sep 2026) quantifies lower dentin microhardness, increased SEM-visible tubule irregularities, and reduced diametral tensile strength in teeth from vegetarian donors versus non-vegetarians.
- Clinical impact: altered dentin properties could affect sealer retention, fracture resistance of endodontically treated teeth, and choice of post materials.
- Authors recommend pre-op dietary history screening and consideration of reinforcement strategies (e.g., fiber posts, cuspal coverage) in vegetarian patients.
- Findings limited to extracted teeth; prospective clinical trials needed to confirm in vivo relevance.
