Benefits of Solea in a Post COVID-10 Environment

Solea lowers the risk of bacteria and virus transmission than the drill

We are still not able to assess the full impact on the medical profession of the COVID-19 epidemic. The guidelines for the dental industry are evolving, but the considerations are clear – reducing the risk of virus and bacteria transmission between patients and staff and patient-to-patient will become a top priority in the post COVD-19 environment.

There are many important differences between the Solea and the Solea.®As they get ready to reopen their doors, practices need to be aware of the all-tissue laser and the traditional drill.

Lower Water Flow and Air Pressure than with the Drill

Water spray is an important factor in aerosolization.

Drills use 1 to 4 water ports. They are driven by a pressure of 38 psi with a flow rate of 30-60 ml/min (Cavalcanti, 2005). Solea can use air pressures as low as 10 PSI and water flows as low as 10ml/min. This is 74% and 67-83% lower air pressures than drills. These factors show that Solea has a significantly lower risk of aerosolization or splatter causing the transmission of viruses including COVID-19 than the drill.

Decontamination of Hard and Soft Tissues

Hard Tissue
Solea vaporizes the tooth structure with thermal energy, rather than using conventional drills. During laser treatment, the surface temperature of the tooth reaches more than 1,200° C without transferring heat to the surrounding tissues. Viruses and bacteria are destroyed at temperatures above 60° C which means Solea kills any virus or bacteria with which the beam comes in contact.*

In contrast, surface temperatures increase by only 11° C when using the drill, allowing viruses and bacteria to survive. Additionally, drills can be cut mechanically with burs rotating up to 400,000 RPM. These burs have been found to project material beyond 18 inches of the mouth cavity, potentially spreading infectious contagions.

Soft Tissue
Solea, a CO2 laser has hemostatic properties (Olivi 2008), (Niemz2003). It delivers energy that acts as a sterilizer by eliminating bacteria and viruses. This is vital for treating periodontal diseases and periimplantitis. The pocket can harbor millions of bacteria. These lasers are a common application and have proven to be very effective.

Expense Savings and Time Savings

Post COVID-19, dentists might be required to change their PPE more often. They may need to change it every time they leave the operatory. This new burden for dentists could lead to significant time and cost increases.

Providers may face a challenge in injecting patients, then returning to the original patient. In situations where multiple patients are required to see each other for different problems, this problem can be even worse.

Solea allows dentists the ability to treat all four quadrants of cavities in one visit and perform multiple soft tissue procedures without the use of local anesthetics. By working without anesthesia, efficiency is increased and four-quadrant dentistry can be achieved. The staff and dentist can stay together in one place without having to wait for the patients to numb. This allows them to work from start to finish with no downtime or additional PPE.


Solea has significant advantages for dental practices, both in soft and hard tissue. This all-tissue laser can significantly reduce aerosols, splatter, through less water flow, air pressure, and kill viruses and bacteria wherever it touches. It can also reduce the need for PPE and allow dental practices to save time and money.

Solea should be considered for dentists who are opening new practices.
