Subgingival is below the gum line and supra gingival is above the gum line

The function of salivary pellicle is is to protect the teeth from erosion, caries and helps to maintain oral health.

# data[].attributes.body
Salivary pellicle is a thin film of protein,lipid's and other molecules that form on surfaces in the mouth.

Day 1 of plaque build up contains 2 different bacteria’s

Salivary Pellice is thin protein film which protects tooth surface from direct contact from acid and bacteria after eating or cleaning teeth

Acute necrosis ulcerative gingivitis is more common in young adults due to bacterial overgrowth

# data[].attributes.body
perio disease is caused by plaque being left on the teeth then hardening up to tartare which causes the gums to become inflamed and start to shrink away from the teeth causing a pocket

There are 3 stages of bone loss - minimal, moderate, severe.

Salivary pellicile is a protein based layer that covers all exposed surfaces on the teeth, this acts a barrier to protect the teeth.

Once the gum has separated from the teeth due to gum disease it is not reversible but it can be stabilised and preventative methods can be done to prevent it getting worse.

Xerostomia smoking bulimia are all factors that increase decay/problems in the teeth/ oral cavity due to acid erosion (bulimia) xerostomia not allowing a buffer to protect the teeth (salivary pennicle) and smoking as it reduces size of blood vessels and reduces saliva

A false pocket is 2 mms and a true pocket is 3 mms or more

Plaque is made up of streptococcus and lactobacilli

Day 1 plaque contains 2 different bacteria’s

Gum disease can not be reversed and only stabilised

# data[].attributes.body
Gingivitis is reversible once there is pockets it’s irreversible

# data[].attributes.body
A periodontal abscess if formed when infection is present in a pocket. This often drains into the mouth. The tooth doesn’t have decay for this to happen.

Gingivitis is the inflammation of the gums and is reversible. This causes the gums to bleed but this will only settle if OH is improved. Once pockets are more than 3mm it is perio. This is irreversible but can be stabilised .

Acute necrotizing ulcerative gingivitis is an acute infection, is really painful, strong smelling, and is most commonly found in age 25-30 year old patients.

A salivary pellicle is a natural barrier to prevent a tooth’s surface from being attacked by acids and to protect it from erosive demineralisation.
