In this type reaction a reactant is replaced by another. The form is like this: A and BC produces AC and B. In this type of reaction, only a single one is replaced by another. Double Replacement: Among the types of reactions and balancing equations this one is very similar to the previous one. The only change is that it has double replacement instead of single replacement.
Extraction of Incisors and Canine Teeth Extraction of the equine incisor and canine teeth requires knowledge of regional and dental anatomy. Incisors are radicular, hypsodont teeth with long reserve crowns that erupt continually throughout the life of the horse. Therefore, as a horse ages incisor extraction should theoretically become easier.
The horse will normally have 24 deciduous teeth, emerging in pairs, and eventually pushed out by the permanent teeth, which normally number between 36 and 40. As the deciduous teeth are pushed up, they are termed caps. horse can have between zero and four canine teeth, also known as tusks (tushes for the deciduous precursor), with a clear prevalence towards male horses (stallions and geldings) who normally have a full set of four. Fewer than 28% of female horses (mares) have any canine teeth.
