Self Etch

Self-Etch Bonding Agents — 6th, 7th & 8th-Generation Self-Etch Adhesives

Self-etch bonding agents are acidic resin monomer adhesives that simultaneously demineralise and infiltrate the smear layer on enamel and dentine in a single clinical step — eliminating the separate phosphoric-acid etch-and-rinse stage. The result is significantly lower post-operative sensitivity because the smear plug is incorporated into the hybrid layer instead of being washed away. Dentalkart stocks 6th-generation two-step self-etch, 7th-generation one-step self-etch and 8th-generation universal adhesives in self-etch mode from Kuraray Clearfil SE Bond, Bisco, Tokuyama, Shofu, Ultradent, Coltène, Nexobio, GC and SafeEndo.

Types of Self-Etch Bonding Agent

6th-generation two-step self-etch (separate primer + adhesive)

Two-bottle 6th-generation self-etch system with a self-etching primer applied first, then a separate adhesive layer light-cured before composite placement — delivers the highest dentine bond strength of any self-etch system and remains the long-term gold standard for posterior composite restorations. For example, Kuraray Clearfil SE Bond Introductory Kits and Shofu FL Bond II (with added fluoride release).

7th-generation one-step self-etch (single-bottle all-in-one)

Single-bottle 7th-generation adhesives that combine the etching primer and bonding resin into one application — etch, prime and bond in a single 20-second rub. Fastest workflow, slightly lower bond strength than 6th-gen on cut enamel. For example, Kuraray Clearfil Tri-S Bond Universal Quick, Tokuyama Palfique 7th Generation Bond, SafeEndo Recreate Bond 7 and Coltène One Coat 7 Universal Bond.

8th-generation universal adhesive (works in self-etch, selective-etch or etch-rinse mode)

Universal adhesives that work in self-etch mode on dentine and selective-etch mode on enamel for the lowest post-op sensitivity combined with reliable enamel bond — the current workhorse for restorative practice. Also bond to zirconia, lithium disilicate and metal without a separate primer. For example, Bisco All-Bond Universal, Shofu Beautibond, Ultradent Peak Universal Bond and Nexobio T-Bond Universal.

Self-etch coating for glass ionomer restorations

Specialty self-etch bonding agent designed to coat the surface of conventional GIC and EQUIA-class restorations to improve early moisture resistance, gloss and surface durability during the acid-base set. For example, GC EQUIA Forte Bond.

When Self-Etch Bonding Agents Are Used

• Direct composite restorations (Class I–V) where post-op sensitivity reduction matters
• Cervical Class V and root-surface restorations on exposed dentine
• Paediatric Class I and II restorations on cooperative children
• Bonded amalgam restorations
• Core build-up under indirect crowns (with dual-cure activator if needed)
• Repair of fractured composite or porcelain margins
• Indirect restoration bonding in self-etch mode (universal adhesives only)
• Coating of freshly placed GIC restorations (EQUIA Forte Bond)

How to Choose the Right Self-Etch Bonding Agent

1. For long-term dentine bond strength in posterior composite restorations pick a 6th-generation two-step self-etch (Kuraray Clearfil SE Bond) — the long-term gold standard.
2. For fast routine direct composite where workflow speed matters pick a 7th-generation one-step (Clearfil Tri-S Bond Universal Quick, Palfique 7th Gen).
3. For mixed enamel-dentine cavities use an 8th-generation universal adhesive in selective-etch mode (Bisco All-Bond Universal, Shofu Beautibond) — phosphoric acid on enamel only, then universal in self-etch on dentine.
4. For caries-active patients prefer a self-etch with fluoride release (Shofu FL Bond II).
5. Apply self-etch with active rubbing for the manufacturer-specified time (typically 20 seconds) — passive application reduces hybrid-layer formation.
6. Store self-etch adhesive bottles upright in the fridge per the manufacturer IFU, dispense onto a paper pad only at use, and cap immediately to prevent solvent evaporation that thickens the adhesive and reduces wetting.

What is a self-etch bonding agent?

A self-etch bonding agent is an acidic resin monomer adhesive that simultaneously demineralises the smear layer and infiltrates the enamel and dentine in a single clinical step. There is no separate phosphoric-acid etch-and-rinse stage. The smear plug is incorporated into the hybrid layer rather than washed away, which significantly reduces post-operative sensitivity.

What is the difference between 6th, 7th and 8th-generation self-etch?

The difference is the number of bottles and clinical steps. 6th-generation is two-step — a self-etching primer first, then a separate adhesive (Kuraray Clearfil SE Bond). 7th-generation is one-step single-bottle all-in-one (Clearfil Tri-S Bond Quick, Palfique 7th Gen). 8th-generation universal adhesives (Bisco All-Bond Universal, Shofu Beautibond) work in self-etch, selective-etch or etch-rinse mode.

Is self-etch as strong as total-etch bonding?

On dentine, modern self-etch matches total-etch for long-term bond strength and has lower post-operative sensitivity. On cut enamel, total-etch (phosphoric acid first) still produces a slightly stronger bond. Selective-etch — phosphoric on enamel only, then universal adhesive in self-etch mode on dentine — combines the strengths of both.

Does self-etch eliminate post-operative sensitivity?

Self-etch significantly reduces but does not entirely eliminate post-operative sensitivity. Because the smear plug is incorporated into the hybrid layer instead of being rinsed away with phosphoric acid, dentinal tubule fluid movement is reduced. Sensitivity can still occur from polymerisation shrinkage, hyper-occlusion or microleakage at marginal gaps.

Are the self-etch bonding agents on Dentalkart genuine and CDSCO-compliant?

Yes, every self-etch bonding agent on Dentalkart is genuine and CDSCO-compliant. All Kuraray, Bisco, Shofu, Tokuyama, Ultradent, Coltène, GC, Nexobio and SafeEndo self-etch adhesives ship in sealed primary packaging with original batch number and expiry printed on every bottle.
