This is referred to as a white spot lesion, an incipient carious lesion, or a "micro-cavity". [13] As the lesion continues to demineralize, it can turn brown but will eventually turn into a cavitation ("cavity"). Before the cavity forms, the process is reversible, but once a cavity forms, the lost tooth structure cannot be regenerated. A lesion ...
Incipient decay may develop in untreated pile tops within 1 year and reach the visible, advanced stage, termed rot, within 2 to 4 years and can extend 4 feet or more from the internally rotting areas of a Douglas-fir pile. [9]
Corpse farms are used to study the decay of the human body and to gain insight into how environmental and endogenous factors affect progression through the stages of decomposition. [8] In summer, high temperatures can accelerate the stages of decomposition: heat encourages the breakdown of organic material, and bacteria also grow faster in a ...
When it comes to repairing teeth affected by Early Childhood Caries, the extent of tooth decay will guide the choice of treatment. For moderate to severe decay, stainless steel crowns are a common option. These crowns are ready-made and can be tailored to fit over a child's primary molar. The crowns are then fixed in place to restore the tooth.

Life on Earth would be so dull without animals. Lucky for us, there are more than 8 million different species of them on the planet, many of which we might never encounter in our lifetime. From ...
It begins at the surface, and may progress into either cavitation (tooth decay) or erosion (tooth wear). Tooth decay demineralization is caused by acids from bacteria in the dental plaque biofilm whilst tooth wear is caused by acids from non-bacterial sources. These can be extrinsic in source, such as carbonated drinks, or intrinsic acids ...
