No it acts as a membrane to which bacteria attach
This is the Occlusal surface
A fissure or a pit is formed in the occlusal surface when multiple cusps join together.
Dental pellicle can be removed by abrasion involving extensive polishing which can only be performed by a dentist. Dental pellicle is the protein film which forms on the enamel surface.
A thin skin or film., A thin film formed on the surface of an evaporating solution.
an area on the occlusal surface of the teeth where the grooves come together or the fissures cross
"Occlusive" is an adjective that refers to the occlusal, which is the chewing surface of molar and pre-molar teeth.
maxillary first molar
When bacteria are grown in broths such as trypticase soy broth (TSB), they may exhibit patterns of growth ranging from a sediment at the bottom of the tube, turbid growth throughout the tube, or a pellicle (thick growth at the top of the tube).
deciduous molar with their occlusal surface below that of adjacent teeth most common is mandibular second deciduous molar may become ankylosed
Those surfaces would be called the Occlusal surface of the posterior teeth.
thyroxine
The evolutionary advantage that would be there to the formation of a pellicle in a liquid medium by a bacterium is they could form colonies and have a greater chance of survival. Two ways to determine motility of a bacteria is using a agar deep or the hanging drop technique.
