Intermediate filaments¹ - unlike microfilaments and microtubules, they are verystable. Instead of being stacked proteins, as in actin, intermediate filaments are built of interlocking proteins. A dense² sheet of intermediate filaments strengthens the nucleus³. Skin cells are filled with keratin, which at the last moment, just before they die. they cross link, to provide a really insoluble barrier layer of the skin. The cross linkage⁴ is between the sulphur atoms of cysteine, one of keratin's amino acids.

Interproximal wear - loss of enamel⁵ on the adjacent surfaces of teeth which is due to continual friction⁶ between the two surfaces as teeth move against each other.

Intratubular dentine - dentine formed inside the tubule by the odontoblast process in response to tooth wear, ageing or arrested caries.

Intrinsic fibres - refers to those fibres of cementum which were laid down by cementoblasts.

Ionised - the loss or gain of an electron from an atom which makes it no longer neutral but an electrically charged ion. If the electron leaves the atom it becomes a positively⁷ charged ion, such when calcium⁸ or sodium⁹ becomes ionised (Ca+, Na+). If the electron is gained, the atom becomes relatively¹⁰ negatively charged such as when chlorine or a phosphate group of atoms lose an electron (Cl-, PO4-). Ionized atoms or groups of atoms are more reactive than when they are neutral.

Ions - an atom or molecules¹¹ which has a net electrical charge This may be caused by the temporary loss (positive ion) or gain (negative ion) of an electron. A calcium ion is written Ca+.

Ipsilateral - the same side as distinct from contralateral. Often used to refer to the teeth, joint¹² or muscles on the same side as chewing is occurring.
