In IUPAC nomenclature, however, hexane is the unbranched isomer (n-hexane); the other four isomers are named as methylated derivatives of pentane and butane. IUPAC also uses the term as the root of many compounds with a linear six-carbon backbone, such as 2-methylhexane (C7H16), which is also called isoheptane.
Dentin is the substance between enamel or cementum and the pulp chamber. It is secreted by the odontoblasts of the dental pulp. The formation of dentin is known as dentinogenesis. The porous, yellow-hued material is made up of 70% inorganic materials, 20% organic materials, and 10% water by weight.
Below the enamel is the dentin that is also a solid part of the teeth. The inner pulp part of the teeth is made up of a soft core that is connected to nerves. In simple terms, dentum in the teeth is mainly made up of calcium.Featured Dental Videos about Teeth.elow the enamel is the dentin that is also a solid part of the teeth.
