Guide to Properly Using Built-in Electric Suction Systems

In dental practice, dental chair built-in electric suction systems are widely adopted due to their efficiency and numerous advantages. While their working principle differs from traditional air suction systems, mastering the proper usage and maintenance of electric suction systems ensures optimal performance. This article explains the working mechanism, usage guidelines, and the benefits of electric suction over air suction.

Working Principles of Electric Suction vs. Air Suction

Air Suction

Air suction systems work by creating a vacuum using pressure differences to quickly remove fluids and debris from the oral cavity. It relies on airflow to suction waste through a vacuum, a commonly used method.

Electric Suction

Electric suction, on the other hand, operates by pushing fluids through water-driven mechanisms. Water enters the system through Water In, driving the motor’s fan, which pushes liquids and debris out through Water Out. Electric suction relies on water flow rather than a vacuum, and requires water intake before starting to ensure the motor functions properly.

Why Choose Electric Suction? Key Advantages

1. Low Noise Operation: Electric suction systems operate with minimal noise, making them suitable for quieter environments. In contrast, air suction systems often produce louder noise, which may cause discomfort for patients.
2. Stable Suction Power: Electric suction provides consistent and stable suction power through water dynamics, unlike air suction, which may fluctuate due to pressure variations. This is ideal for long, complex procedures.
3. Energy Efficiency: Electric suction systems consume less energy and have a simpler structure, eliminating the need for large air compressors, leading to lower maintenance costs.
4. Reduced Aerosol Generation: Since electric suction is driven by water, it helps reduce aerosol generation during procedures, enhancing safety within the clinic.

Key Steps for Proper Use of Built-in Electric Suction

1. Inject Water Before Use
   Before using the system, ensure a sufficient amount of water is injected into the system to allow the motor and fan to start working properly.
2. Clean the System After Use
   At the end of each day, flush the system with clean water to remove blood, saliva, and other debris from the motor and tubing to prevent clogs and maintain the system’s functionality.

Common Issues and Solutions

• Weak Suction: This typically occurs when there is insufficient water before use. Ensure that enough water has been injected into the system.
• Increased Noise or Poor Performance: This could indicate clogged tubing. Make sure to clean the system thoroughly with water after each use.
• Motor Malfunction or Failure to Start: Check the water flow and cleanliness of the system, ensuring there are no blockages.

Compared to air suction systems, electric suction offers lower noise, stable suction power, energy efficiency, and enhanced safety by reducing aerosols. With proper usage and regular maintenance, built-in electric suction systems can provide reliable, long-term support for dental clinics, improving operational efficiency and patient comfort.
