Tori, Torus, Exostoses

Is it due to ionization?

Tori: Non-pathologic outgrowth of bone.

I believe this is one way bone responds to stresses

applied to it.

2

HypothesisTori are very common in today’s population (2004). I believe they are a result of stresses on the bone and are mainly found on nervous, anxious and driver-type personalities. The significant increase in the number and size of tori seen today as compared to prehistoric times are the result of society stresses.

Tori, I believe, will not be found in prehistoric skulls in the frequency or size of today’s tori. Prehistoric man had stresses, but their stresses were the result of survival, not of society stresses.

Difference will be in frequency (can be seen on a daily basis in dental offices today) and size (massive today – not as massive in prehistoric times).

3

ToriMay be genetically linked.

20-25% of people have them.

Females more affected.

Mendelian Dominate.

Evidence of what causes them is lacking.

40-60% of children of parents who had them, will have them.

‘Lips together - teeth apart.’

Only time your teeth should be squeezed together and touching is when you

swallow. Even when you are eating there are usually food particles keeping

your teeth apart.105
