National Board Dental Hygiene Examination (NBDHE) Dental Hygienist Practice Test

Which instrument is designed to reduce trauma to the surfaces of dental implants during cleaning?

1. Stainless steel scaler

2. Plastic resin scaler

3. Metal curette

4. Regular hand scaler

The correct answer is: Plastic resin scaler

The instrument specifically designed to reduce trauma to the surfaces of dental implants during cleaning is the plastic resin scaler. Dental implants are made from materials that can be sensitive to abrasive forces, and using instruments that can scratch or damage the implant surface is a significant concern. Plastic resin scalers are crafted from non-metal materials, ensuring that they effectively remove plaque and tartar accumulation without harming the delicate surfaces of the implants. Their design allows for effective cleaning while minimizing the risk of implant surface abrasion or scratching, which could potentially lead to complications such as peri-implantitis. In contrast, stainless steel scalers, metal curettes, and regular hand scalers can all be too harsh for implant surfaces. These metal tools are effective for traditional teeth cleaning but can easily create micro-scratches or other damage to the implant surface, leading to higher risks of infection and implant failure. Therefore, the use of plastic resin scalers is essential for maintaining the integrity and longevity of dental implants.
