Total Etch

Total Etch Bonding Agents — 5th-Generation Etch-Rinse Adhesive Systems for Maximum Enamel Bond

Total etch bonding agents are 5th-generation two-step adhesive systems that use a separate 37% phosphoric acid etch on enamel and dentine, followed by a single-bottle bonding resin applied to moist dentine and light-cured. The etch-rinse step demineralises 5–10 µm of enamel rod and exposes the dentine collagen network, producing the highest enamel bond strength of any adhesive chemistry — still the long-term gold standard for indirect restoration bonding and large composite restorations. Dentalkart stocks total-etch 5th-gen bonds, 37% phosphoric acid conditioners and universal adhesives used in etch-rinse mode from Bisco, Dentsply, Coltène, SDI, Dentgist, Septodont, Bond Plus and GC.

Types of Total-Etch Adhesive System

5th-generation single-bottle total-etch bonding agent (etch-rinse)

Classic 5th-generation single-bottle adhesive — phosphoric acid etch first, rinse and lightly dry, then apply the bonding resin to moist dentine and light-cure. Highest enamel bond strength, ideal for indirect restoration bonding. For example, Dentgist Bonding Agent 5th Gen, Coltène One Coat 7 Universal Bond, Coltène SwissTec SL Bond, SDI Stae Bond and Bond Plus NT.

8th-generation universal adhesive in etch-rinse mode

Universal adhesives that work in etch-rinse mode on enamel and dentine for peak enamel bond, or in self-etch / selective-etch mode for lower post-op sensitivity — the most versatile current chemistry. For example, Bisco All-Bond Universal.

37% phosphoric acid conditioner (etchant for total-etch workflow)

Premium 36–37% phosphoric acid gel for the etch-rinse step of total-etch bonding — 15 seconds on enamel, 10 seconds on dentine, rinse 15 seconds, blot dry to leave moist dentine. For example, Dentsply Detrey Conditioner 36 and Septodont Septo-Etch.

Self-etch GIC coating (paired use with total-etch composite layer)

Specialty self-etch coating for sealing freshly placed GIC restorations against early moisture contamination. For example, GC EQUIA Forte Bond.

When Total-Etch Bonding Is Used

• Indirect restoration bonding — porcelain veneers, all-ceramic crowns, lithium disilicate inlays / onlays
• Large direct composite restorations on enamel-bordered cavities (Class II, IV, V)
• Bonded amalgam restorations
• Core build-up under indirect crowns (dual-cure activator)
• Bonded post cementation
• Repair of fractured porcelain restorations
• Orthodontic bracket bonding (etch-rinse mode preferred for retention)
• Class IV anterior composite where peak enamel bond drives aesthetic-edge longevity

How to Use Total-Etch Bonding Correctly

1. Etch enamel with 37% phosphoric acid for 15 seconds, then extend onto dentine for the final 10 seconds — total 15 s enamel, 10 s dentine.
2. Rinse thoroughly for 15 seconds; do not over-dry — leave the dentine visibly moist (wet-bonding) to keep the collagen network expanded.
3. Apply the 5th-gen bonding agent in two consecutive coats with a microbrush, gently air-thin for 5 seconds, then light-cure 10 seconds.
4. Place composite in 2-mm increments immediately after cure — delay reduces bond strength.
5. For universal adhesives in etch-rinse mode, follow the same etch-and-rinse protocol then apply per the manufacturer IFU.
6. Avoid contamination with saliva or blood after etching — re-etch for 5 seconds if contaminated.

What is a total-etch bonding agent?

A total-etch bonding agent is a 5th-generation adhesive system that uses a separate 37% phosphoric acid etch on enamel and dentine, followed by a single-bottle bonding resin applied to moist dentine and light-cured. The etch-rinse step demineralises enamel rod and dentine collagen for micromechanical infiltration — producing the highest enamel bond strength of any adhesive chemistry.

What is the difference between total-etch and self-etch?

The difference is whether the etch is a separate step. Total-etch (5th-gen, etch-rinse) uses phosphoric acid as a separate first step — peak enamel bond, more post-op sensitivity. Self-etch (6th–8th gen) combines etching with bonding — lower post-op sensitivity, slightly lower enamel bond on cut enamel. Selective-etch combines both for the best of each.

When should I use total-etch bonding?

Use total-etch bonding for indirect restoration bonding (porcelain veneers, all-ceramic crowns, lithium disilicate inlays and onlays), large direct composite restorations on enamel-bordered cavities (Class II, IV, V), bonded amalgam, core build-up under cast crowns, and orthodontic bracket bonding — any case where peak enamel bond strength drives long-term retention.

What is wet bonding in the total-etch technique?

Wet bonding is the technique of leaving the etched dentine visibly moist (not air-dried) before applying the 5th-gen bonding resin. The water keeps the demineralised collagen network expanded, allowing the resin monomer to infiltrate the full depth of the etched layer. Over-drying collapses the collagen and reduces bond strength by up to 50%.

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

Yes, every total-etch bonding agent and etchant on Dentalkart is genuine and CDSCO-compliant. All Bisco, Dentsply, Coltène, SDI, Dentgist, Septodont, Bond Plus and GC products ship in sealed primary packaging with original batch number and expiry printed on every bottle and syringe.
