Early stages of decay (white spot lesions) and initial enamel damage are managed with non-invasive preventive methods and are closely monitored over time. High-risk children typically need more intensive treatment. This may include early restorative work to repair and address any existing decay to prevent further deterioration of the teeth.
Aggressive treatment, by filling, of incipient carious lesions, places where there is superficial damage to the enamel, is controversial as they may heal themselves, while once a filling is performed it will eventually have to be redone and the site serves as a vulnerable site for further decay. [13] In general, early treatment is quicker and ...
A systematic review concluded that for decayed baby (primary) teeth, putting an off‐the‐shelf metal crown over the tooth (Hall technique) or only partially removing decay (also referred to as "selective removal" [5]) before placing a filling may be better than the conventional treatment of removing all decay before filling.

Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments (dental drills) to prepare the tooth and can be performed in settings with no access to dental equipment.
Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha, beta, and gamma decay.
Some α emitting isotopes such as 225 Ac and 213 Bi are only available in limited quantities from 229 Th decay, although cyclotron production is feasible. [9] [10] [11] Among alpha-emitting radiometals according to availability, chelation chemistry, and half-life, 212 Pb is also a promising candidate for targeted alpha-therapy.

Radium-223 (223 Ra, Ra-223) is an isotope of radium with an 11.4-day half-life.It was discovered in 1905 by T. Godlewski, [2] [3] [4] a Polish chemist from Kraków, and was historically known as actinium X (AcX).
