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.
Causes[edit] Extra teeth, lost teeth, impacted teeth, or abnormally shaped teeth have been cited as causes of malocclusion. A small underdeveloped jaw, caused by lack of masticatory stress during childhood, can cause tooth overcrowding.
