Lightweight, low-noise, high-performance: Dentsply Sirona Instruments

Noise as a stress factor at the dental practice

Rotating instruments, suction systems and other sources of noise: Many devices at the dental practice generate a noise level reaching up to 90 decibels – 5 dB over the limit value for possible hearing impairment. The frequency of the noise plays a major role in this aspect: Contra-angles and turbines generate high-frequency noise directly at the ear of the dentist and of the patient. The instrument noise creates additional strain for the dental intervention. The patient feels uncomfortable, tenses up and in the worst case becomes a phobic patient.


The impact of noise on the dental team

Dentists and their assistants are also exposed to high noise levels daily. Even contra-angles and turbines operating far below 85 dB generate a high noise level. The body reacts with stress:1 It produces hormones such as adrenaline, noradrenaline and cortisol. Blood pressure increases and in the long term it can result in headaches, muscle stiffness, gastrointestinal problems or sleep disorders.2 These factors cause a performance drop and concentration difficulties for the dental team and they can lead to mistakes at work.3

In particular, the smell of the dental practice and certain sounds such as the drill are especially bad for many patients.

The new red contra-angle by Dentsply Sirona – quieter than ever before

If you would like more peace of mind for both you and your patients, use the new red contra-angle from Dentsply Sirona in classes T1 and T2. As a result of continuous development efforts, the rotating instrument is significantly quieter than the previous model, and it is one of the lowest-noise models on the market today. The new contra-angle not only works very quietly, it is also very lightweight, provides optimum visibility during treatment and offers a constantly high performance output:
