Types of location of 3rd Molar root to Inferior Alveolar Nerve Canal
The 3rd molar is the most commonly impacted tooth in the whole dentition because of the timing of eruption and the lack of length of Jaw which has been decreasing over generations thanks to Evolution. During 3rd molar impaction of the Mandible there are many factors which should be considered before going for Surgical removal […]
What are the Supporting Cells of Taste Buds
Taste Buds are the cells or group of cells which help in taste perception. The location of Taste buds is mainly on the inner walls of the trough surrounding the vallate papilla, in the folds of the foliate papillae, on the posterior surface of epiglottis, and on some of the fungiform papillae at the tip […]
What is Stippling of Gingiva and how is it formed and where it is seen

It is also called as Alternate protuberances & depressions on gingival surface. Stippling was thought to indicate good gingival health, but it has since been shown that smooth gingiva is not an indication […]
Rare Impaction of 3rd Molar between Roots of Adjacent tooth
Here are some images of Impacted teeth which are very Rare and we do not know whether they are Developmental Disturbances or Impacted Teeth. There are many types of Wisdom teeth Impactions depending on various factors which aid in its classification. Various authors have classified Wisdom Teeth like Archer, Pell and Gregory, Winters classification etc. […]
