Simply deduct this from the gross figure. I am assuming a vat rate of 17.5%. I have tried to show the underlying methodology, because if the vat rate changes you won't understand how to re-calculate. If the vat rate was 20% you would multiply the gross by 20 and divide by 120.
2013 2 Apr. A dental ABFRACTION is a notched-out area on the root of a tooth at the gumline. There are several causes for this. It can be caused by toothbrush wear over a period of timeâ¦usually by vigorous brushing in certain areas or by the use of a hard-bristled toothbrush.
It come from a frequent rubbing or scraping against the tooth surface, that over time results in the loss of some tooth tissue. This is caused in most cases by our trusted friend the tooth brush being used over zealously. Toothbrush abrasion is by far the most common cause; so much so that 'abrasion' and '.brasion is a term we use to describe mechanical wear that comes from something other than teeth.
