Heavy staining and calculus deposits exhibited on the lingual surface of the mandibular anterior teeth, along the gumline Calculus deposit (indicated with a red arrow) on x-ray image. In dentistry, calculus or tartar is a form of hardened dental plaque.
[11] These imaging techniques use ion radiation to make detailed images of the internal structure of body parts which are vital roles in healthcare for diagnostic and therapeutic purposes. The implementation of preventive measures is essential in order to decrease the risk of exposure and to make sure healthcare workers are safe and protected.
A dental laser is a type of laser designed specifically for use in oral surgery or dentistry.. In the United States, the use of lasers on the gums was first approved by the Food and Drug Administration in the early 1990s, and use on hard tissue like teeth or the bone of the mandible gained approval in 1996.

Scaling and root planing, also known as conventional periodontal therapy, non-surgical periodontal therapy or deep cleaning, is a procedure involving removal of dental plaque and calculus (scaling or debridement) and then smoothing, or planing, of the (exposed) surfaces of the roots, removing cementum or dentine that is impregnated with calculus, toxins, or microorganisms, [1] the agents that ...
English: Radiation Dose Chart by Randall Munroe as part of the webcomic xkcd (SVG version of ). In response to concerns about the radioactivity released by the Fukushima Daiichi nuclear disaster:Fukushima Daiichi nuclear disaster in 2011, and to remedy what he described as "confusing" reporting on radiation levels in the media, Munroe created a chart of comparative radiation exposure levels.

The energy-depth-dose profile is a curve starting with a surface dose, ascending to the maximum dose in a certain depth d m (usually normalized as 100% dose), then descends slowly through depths of 90% dose (d 90) and 80% dose (d 80), then falls off linearly and relatively sharply though depth of 50% dose (d 50).
Irradiation is the process by which an object is exposed to radiation. An irradiator is a device used to expose an object to radiation, notably gamma radiation , for a variety of purposes. [ 1 ]
