In dentistry, the linea alba (from Latin 'white line') [1] is a horizontal streak on the buccal mucosa (inner surface of the cheek), level with the occlusion (biting plane). ). It usually extends from the commissure to the posterior teeth, and can extend to the inner lip mucosa and corners of the mo
The presence of the dark lines is similar to the annual rings on a tree. They are named after Swedish anatomist Anders Retzius. In the longitudinal section of a tooth, these lines appear near the dentin. They bend obliquely near the cervical region. They curve occlusally near the cuspal regions or the incisal regions.
They develop where the mucosa is subjected to chronic minor irritants, mechanical or infective. They most frequently occur on the buccal mucosa (inner cheek) along the occlusal line where the teeth meet and the gingivae (the mucosa which covers the gums); reactive nodules occurring here are specifically categorised as epulides instead of polyps.

The clinical manifestation of mild dental fluorosis is mostly characterised a snow flaking appearance that lack a clear border, opaque, white spots, narrow white lines following the perikymata or patches as the opacities may coalesce with an intact, hard and smooth enamel surface on most of the teeth.

The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone.It forms a partition between the nasal passages and the mouth.On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
