Review of the Most Popular Rotary Files

With continuous rotation and advanced design, these files make the process of cleaning and shaping the root canal faster, safer, and more precise. In Iran, given the increasing demand for high-quality and cost-effective equipment, brands such as M3, Denco, MicroMega, and Eighteeth have quickly gained popularity. Based on market reviews and expert opinions, the review of the most popular rotary files often involves models featuring Heat Activation technology, which offers high flexibility and resistance.

In this article, we review the most popular rotary files and provide a guide for selecting the best option based on clinical needs.

Introducing the Most Popular Rotary File Brands in Iran

Iran has a dynamic market for endodontic equipment, with high-quality Chinese and European brands capturing a significant share. Based on online surveys and educational videos (such as Dentocourse reviews), the following brands top the list of popular rotary files in Iran:

• M3 Pro Gold Rotary File: This Chinese file, made with Heat Treated Nickel-Titanium alloy, offers extraordinary flexibility and excellent cutting power. Its diverse sizes (from 10/.04 to 30/.06) make it suitable for both straight and curved canals. The M3 Retreatment File is also ideal for re-treatments, featuring a non-cutting tip design that removes residual tissues without damaging the walls. Approximate price for a pack of 6: 800,000 to 1,000,000 Tomans.
• 2Shape MicroMega: A French product featuring T-Wire technology, which performs canal cleaning with just two files (TS1 and TS2). Continuous 360-degree rotation and high flexibility make it ideal for complex canals. This file is popular in the Iranian market due to its high durability (double resistance to cyclic fatigue).
• Denco Gold/Blue: The Chinese brand Denco is known for two models: Gold (high cutting power for posterior roots) and Blue (flexible for curves). Denco Gold/Blue, with a reasonable price (about 500,000 to 700,000 Tomans per pack) and quality competitive with European brands, is the first choice for many clinics.
• IMD M-Taper: An advanced file with a conical design and 4-6% taper, suitable for precise shaping. High fracture resistance and a price of around 600,000 Tomans have made it an economical option.
• Neolix Rotary File: Focusing on safety and speed, this Korean file is excellent for routine treatments. High flexibility and a non-cutting design reduce the risk of perforation.
• E-Flex Blue (Eighteeth): A Chinese file with Heat Activation, offering flexibility similar to Denco Blue but focused on narrow canals. Pack price: ~700,000 Tomans.
• Additionally, the Dentsply brand with models like EdgeFile X3 is included in the introduction of popular rotary file brands in Iran, although it is slightly more expensive.

Comparison of 2Shape and EdgeFile X3 Rotary Files

Among Iranian specialists, the comparison of 2Shape and EdgeFile X3 rotary files is a hot topic.

2Shape (MicroMega), with a two-file system (TS1: 15/.04 and TS2: 25/.04), continuous rotation, and high flexibility, cleans 90% of canals in less than 5 minutes. With its Heat-Treatment process, this file has double the fatigue resistance of standard models and is ideal for curved MB2 molar canals.

In contrast, EdgeFile X3 (Dentsply) with X3 Boost technology (variable taper 3-9%) offers more aggressive cutting and is more suitable for calcified canals. However, it has less flexibility compared to 2Shape, and the risk of separation (breakage) is higher in severe curves. Based on clinical reviews, 2Shape is more popular in Iran because it is more compatible with common devices like NSK and has a lower price (about 20% cheaper). The final choice depends on the canal anatomy: 2Shape for complex cases, EdgeFile for rapid cutting.

Pros and Cons of Blue and Gold Rotary Files (Heat Activation)

Heat Activation technology in Blue and Gold files alters the NiTi alloy structure and increases flexibility. Which is better for root canal treatment: Denco Gold or Blue? It depends on the canal type:

• Pros and Cons of Gold Rotary Files:

  • Pros: Excellent cutting power (twice that of standard models), high fracture resistance, suitable for anterior and posterior roots with mild curvature.

  • Cons: Less flexibility in severe curves (risk of canal transportation/deviation), requires lower speed (250-300 rpm).

• Pros and Cons of Blue Rotary Files:

  • Pros: Maximum flexibility (up to 3 times that of Gold), ideal for curved and calcified canals, reduced risk of perforation.

  • Cons: Slightly weaker cutting (suitable for final shaping), higher price in some brands.

How to Select Sizes: Sx, S1, S2, F1-F3

Selection of Sx, S1, S2, F1-F3 sizes based on the ProTaper protocol (common in most brands):

1. Sx (19mm, Taper 0.03): Coronal opener, for removing obstructing dentin. Initial use after hand file #10-15.

2. S1 (18/.04): Initial shaping, for narrow canals (Tip #18).

3. S2 (19/.04): Middle expansion, suitable for upper molars (Tip #19).

4. F1-F3 (20-30/.06): Finishing, for final tapering (F1: Tip #20, F3: #30). Proceed from small to large to maintain the conical shape.

Recommendation based on radiography: Start with Blue S1-S2 for curved canals; use Gold F1-F3 for straight canals.
