Malayan Sun Bear – Part 1 The helarctos malayanus, commonly known as sun bear, is the smallest breed of bear in the world. An average a fully grown sun bear will weigh between 30kg and 60kg and will be 120cm to 150cm tall. A sun bear’s fur is also short and thick so that their fur doesn’t get stuck on branches but can still offer protection from branches so the sun bear doesn’t get scratched.

no teeth.5 How Streptococcus mutans causes dental caries. S. mutans is the main initiator of dental caries in human subjects because of a variety of factors. First, S. mutans can bind to tooth surfaces.1 S. mutans expresses adhesion that can bind to salivary glycoprotein that is on the tooth surface.8 The tooth surface is negatively charged and thus attracts proteins (glycoproteins) on its surface forming a layer called…

teeth get darker. The bulk of the tooth consists of dentin. Dentin is a substance that is kind of like bone but it is harder. Covering the dentin is a tough durable layer named enamel. “ Enamel is composed primarily of calcium phosphate and is the hardest substance in the body.” (Graaff & Fox 1999) “Enamel consist of approximately 97% calcified (inorganic) materials and only 3% organic material and water.” (Thibodeau & Patton 1999) That means that the tooth is not like any other part of the…

world. This is the process of when fluoride is added to water to prevent tooth decay, which toughens the enamel of teeth in children and adults, but has been a health issue in communities (“Fluoride Information Network”, n.d). The way that tooth decay forms is with bacteria that make acid to remove minerals from teeth. Therefore, fluoride prevents the cavities from expanding throughout the mouth. Other than just preventing tooth decay, water fluoridation prevents infection, loss of teeth, pain,…
