Oral irrigation is aka

Water flosser

Water flossers lower

Bleeding and gingivitis

Water flossers recommended for what?

pretty much everything

How to use a water flosser

Lean over sink, turn on unit LOW, then increase to a higher pressure

Dentifrice is

toothpaste

Less common interdental tools

Single-tuft brush, interdental tip, toothpick holder, wooden interdental cleaner

Benefits of dentifrices (5)

Prevent caries, reduce biofilm formation, reduce gingivitis, reduce dentinal hypersensitivity, reduce supragingival calculus formation

Ingredients that prevent caries

Fluoride + xylitol

Ingredients that reduce biofilm formation

Zinc citrate, stannous fluoride

Ingredients that reduce gingivitis

Stannous fluoride

Ingredients that reduce dentinal hypersensitivity

Potassium nitrate and sodium fluoride

Ingredients that reduce supragingival calc formation

Pyrophosphate salts, zinc salts, sodium hexametaphosphate

Cosmetic effects of dentifrices

Remove extrinsic stain, reduce halitosis

Inactive components of dentifrices (6)

Detergents, cleaning/polishing agents, binders, humectants, preservatives, flavoring

Detergents do what?

Foam and loosen surface deposits

Cleaning/polishing agents do what?

Smooth tooth

Binders do what? (think peanut butter)

Chlorhexidine is recommended for…

Pre-procedural rinse, perio debridement, immunocompromised pts, post-surgery

Oxygenating agents in mouth rinses do what?

Alter cell membrane, increasing permeability

Quaternary ammonium in mouth do what?

rupture cell wall, decreasing bacteria ability to attach to the pellicle

Phenolic-related essential oils Mechanism of action

Disrupt cell walls, decrease pathogenicity of biofilm

Alcohol function in mouth rinses

Enhances flavor impact and contributes to cleansing
