A suction tool for connection to a dental suction system can include an elongate body, a tip portion, and a screen mechanism positioned within the elongate body. The tip portion can extend over at least a portion of the elongate body. The tip portion can include an upper portion and a lower portion integrally formed with the upper portion and at least partially spaced apart from the upper portion by a recessed portion.

Hygiene regulations and social distancing are very effective in blocking short distance infections. During the lockdown, the distance rules can usually be adhered to, but what happens when the actual lockdown is over and the people meet again in a confined space? Then additional effective and efficient protection is essential to stabilize infection rates. Since the viruses are spread by contact and droplet infection, technical devices are required that effectively intervene in the chain of infection and effectively block infection. An effective protection is the respiratory mask as known since 100 years. An alternative to mask is an aerosol protection system for various applications in environment. The protection system consists of adjustable air sucking device and air blowing device in different form factors based on application. The aerosol protection system uses either an air curtain or air shield to prevent the aerosol going from one side of the curtain or shield to the other side.

A compact extraoral suction passage tip to help protect a dentist from infectious materials. The compact extraoral suction passage tip is made of an internal suction passage. The proximal end can be slid into a High Volume Evacuator (HVE) valve or other suctioning device, and the distal end can be placed near a patient's mouth to collect infectious materials and placed in a position that will not significantly impede dental operations. The distal end is shaped so that it can lie on or near the upper portion of a patient's bottom lip to provide suction capability. One embodiment contains ridges to help patients know where to hold the compact extraoral suction passage tip.

Various implementations include a dental suction device configured to be disposed on a toothbrush having at least one bristle head. The dental suction device includes a main conduit, at least one pair of secondary conduits, and a shaft. The main conduit includes a first end and a second end spaced apart from the first end. Each of the secondary conduits includes a first end and a second end spaced apart from the first end. The first end of each of the secondary conduits is connected in fluid communication with the main conduit. The shaft is coupled to and disposed between the pair of secondary conduits. The shaft is shaped to receive and retain a portion of the toothbrush in between the pair of secondary conduits such that the pair of secondary conduits is configured to apply suction at least subjacent the bristle head.
