⭐ High-Yield Facts for Exam

  • Gutta-percha = core material.
  • AH Plus = popular epoxy sealer.
  • Lateral condensation = classic gold standard.
  • Warm vertical = Schilder technique.
  • Goal = 3D seal to apical constriction.

Obturation

Obturation is the three-dimensional filling of the cleaned and shaped canal system to prevent reinfection.

Materials

  • Gutta-percha — the most common core material (β-form in points).
  • Sealer — fills voids and bonds GP to dentin; AH Plus (epoxy resin) is widely used. Bioceramic sealers are increasingly popular.

Techniques

  • Cold lateral condensation — traditional gold standard; spreader compacts accessory points.
  • Warm vertical compaction (Schilder) — better fills lateral canals/irregularities.
  • Thermoplasticised/carrier-based systems for speed.

Ideal Endpoint

A dense fill to the apical constriction with a good apical seal and no voids.

Exam Tips ⭐

GP = core; AH Plus = popular sealer; lateral condensation = classic gold standard; warm vertical = Schilder.
