Deep pits and grooves can be found on the chewing surfaces of the back teeth.
Such pits and grooves are termed 'fissures' and are usually so narrow that toothbrush bristles and streams of water are not able to clean them effectively..
Bruxism: bruxism is usually the main cause of the appearance of dental fissures.
It markedly wears the surface of the tooth, this leads to the piece gradually weakening.
It should be added that the continuous pressure exerted can also lead to the appearance of dental fissures..
Tooth fissures are deep pits and grooves on the surfaces of the teeth.
They are particularly common in children and teenagers and can often cause cavities in the back teeth (molars) where they are normally found.
As tooth fissures are very narrow it is difficult to clean inside them when you brush your teeth..
Pits and Fissures are natural in tooth anatomy, however they can deepen over time.
Deep pits and fissures are the small holes and lines that can be seen on the biting surface of a tooth.
These pits and fissures often trap food and can harvest bacteria, leading to dental caries..
Internal fissures: these can cause quite intense pain in the tooth, as they pass the surface layer of the piece.
They can even affect dentin, leading to nerve damage.
In the event of a nerve problem, an endodontic solution would be required to save the piece..
Definition.
English.
The occlusal fissure is located on the occlusal surfaces of premolar and molar teeth, as variable shaped longitudinal furrow with transverse branches..
Caries in the pits and fissures follows the direction of enamel rods and characteristically forms a triangular or cone shaped lesion with its apex at the outer surface and its base towards DEJ.
Pits and fissures provide greater cavitations than smooth surface caries..
The fissure is formed by the free borders of the upper and lower lips that join each other in the corners of the mouth or commissures (Fig
2 1 )The lips (labialis, superioris, and inferioris) are mobile musculofibrous folds that meet laterally to form the cephalometric point, cheilion ( g, lips)
External surface features of the oral fissure are complex and clinically important
The contour of the line formed by the vermilion border of the upper lip is called “Cupid’s bow” (Carey et al
2009 )The upper lip is further characterized by an indentation of the vermilion border in its central part
The average fissure depth of the individual tooth ranged from 120 to 1050 μm
The average width in the middle part of the fissure varied between 40 and 156 μm, the average thickness of the enamel at the bottom of the fissure was between 270 and 1008 μm, and the occlusal angle was between 51
6 and 84 5° [ 11 ]Deep dental fissures are a natural part of a tooth’s anatomy, to a point. They exist to create a variable chewing surface that allows us omnivores to properly chew our food. However, some dental fissures can extend far below the enamel, allowing bacteria to enter and damage the teeth.
Groove—narrow linear depression (1) Fissure—structural effect of enamel formation manifested as developmental lines or grooves on the external surface of a tooth; the area where the centers of calcification coalesce during tooth development
