1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

aimTo describe the use of a new protective device to reduce aerosol dispersion in dental clinics during the COVID-19 pandemic. METHODOLOGY: The device consists of a rigid translucent acrylic structure (methyl polymethacrylate), adjusted to the dental chair, involving the patient's head, neck and chest. There is also a piping system to generate negative pressure, for aspiration and filtering of the air inside the device chamber. The operator works through small holes in the acrylic structure, to reduce contact with the microparticles arising from aerosols during dental procedures. Simulated dental procedures using a fluorescent dye in the water of the dental equipment were carried out, with and without the use of the device. The presence of the dye was analysed at various locations, such as on personal protective equipment (PPE), the dental chair and on the clinic floor.

resultsIn the simulated dental procedure without the device, the dye was obvious on surgical gloves, aprons (waist, chest, legs, fists) and face shields, as well as on the dental chair (backrest, light reflector) and clinic floor. In the simulated dental procedure using the device, the dye was observed only on surgical gloves, apron (fists), inside the pipe system and internal walls of the acrylic chamber. There was a certain limitation of movement and visualization by the dentist whilst using the device.

conclusionsThe present device is a low-cost complementary resource for use in conjunction with standard PPE, to reduce the transmission of SARS-CoV-2 in the dental setting. Further clinical trials should be carried out to test the efficacy of this device to reduce aerosol dispersion and the consequent vector of contamination, as well as the ergonomic impacts related to its use.
