Root canal treatment is the core technology of modern endodontics. Under the abundant illumination and magnified field provided by the dental operating microscope, clinicians can clearly identify the intricate structures of the root canal system and manage complex cases that are difficult to resolve with conventional treatment. However, the microscope serves only as the “eyes” — what truly determines treatment success are the precision instruments held in hand, perfectly coordinated with the microscopic view.

HDY Medical has developed a comprehensive diagnostic and root canal instrument solution centered around the three core stages of microscopic root canal therapy: exploration, debridement, and obturation.

I. Exploration & Localization: The “First Touchpoint” Under Microscopy

The first step in microscopic root canal treatment involves precisely locating root canal orifices, exploring calcified canals, and assessing pulp chamber anatomy under 8–25× magnification.

HDY KB Mirror Handle + K05 Single-Sided Mouth Mirror: The ultra-clear mirror head refracts light within the narrow pulp chamber, expanding visual blind spots — serving as the clinician’s “second pair of eyes.” Paired with an ergonomic plastic handle, it remains comfortable even during prolonged procedures.

HDY TZDG16 DG16 Endodontic Explorer: The fine, sharp working tip delivers exceptional tactile sensitivity. The clinician gently “scrapes” along the junction between the pulp chamber floor and cavity walls, using the catch sensation to precisely locate root canal orifices and assess calcified boundaries. This is the irreplaceable “golden tool” of microscopic root canal exploration.

Application Tip: Explore with gentle, precise movements. Use the explorer to trace the junction of the pulp chamber floor and walls to detect catch points, avoiding excessive force that could cause lateral root perforation.

II. Debridement & Shaping: The “Fine Channel Battle” in Calcified Canals

Debridement of calcified canals, C-shaped canals, and retreatment cases represents the most challenging phase of microscopic root canal therapy.

HDY WG15 Oval Spoon Endodontic Excavator (1.5mm): A precision endodontic instrument specifically designed for root canal treatment. Its 1.5mm oval spoon-shaped working end provides excellent maneuverability and access within narrow root canal spaces, efficiently removing soft tissue and debris. When used under microscopy, it allows precise control over excavation depth and range.

Note: When operating under the microscope, keep the lens clean and free from debris that may obstruct the field of view. Clean the excavator promptly after use to prevent tissue residue from compromising sterilization effectiveness.

III. Root Canal Obturation: The “Precision Synergy” of Locking Dressing Forceps and Pluggers

Root canal obturation is the critical determinant of long-term treatment outcomes. Under microscopy, the clinician frequently handles cotton pellets, paper points, gutta-percha cones, and other small items for drying, trial fitting of the master cone, sealer application, and final obturation. Every second of this stage places exceptionally high demands on the instrument’s stable gripping capability.

HDY N19S Locking Dressing Pliers: Featuring a built-in self-locking mechanism that provides stable and secure gripping force, this is the ideal tool for holding cotton pellets, paper points, gutta-percha cones, and other small items​ during microscopic root canal obturation. Under the microscope, once the clinician locks the forceps, finger pressure can be completely released, allowing full concentration on observing instrument seating and material flow. This effectively prevents risks such as cotton pellet displacement, paper point slippage, or accidental gutta-percha cone ejection, while significantly reducing hand fatigue during prolonged microscopic procedures.

HDY CTG01 Root Canal Plugger (0.4/0.7mm) / CTG02 Root Canal Plugger (0.5/0.8mm) / CTG03 Root Canal Plugger (1.0mm/Paddle Tip): Dual-ended designs covering the full size spectrum from fine, curved canals to wider canals. Used in conjunction with warm gutta-percha techniques under real-time microscopic observation, these pluggers vertically condense the gutta-percha tightly into isthmuses and irregular areas of the root canal system, achieving true three-dimensional hermetic sealing.

Operational Points:

• When using the N19S locking dressing plier to hold the master gutta-percha cone, lock the forceps and gently advance the cone into the canal to ensure precise seating
• After applying sealer, use the locking dressing forceps to hold a paper point for uniform coating of the canal walls
• Vertical condensation must be performed under real-time microscopic observation of gutta-percha flow and adaptation to canal walls; apply even pressure and avoid excessive force

IV. Integrated Storage: HDY Instrument Cassettes — Ensuring Clinical Efficiency

Microscopic root canal treatment places elevated demands on instrument cleaning, sterilization, and organized management. The HDY instrument cassette series (/H1001) features one-piece stamped upper and lower covers with no welded seams, providing robust construction and corrosion resistance. Built-in high-elasticity silicone dividers securely hold instruments of varying diameters, preventing collision during transport. Dual-point locking clasps ensure the cassette remains tightly sealed throughout sterilization and transfer, maintaining sterility.
