#2: Toothbrushing

Bristles and Filaments
Most tb today are Nylon Natural bristles: unsanitary Factors influencing stiffness Depends on diameter and length of the filament Diameter: thinner = softer and more resilient Length: shorter are stiffer and less flexible Angle of filaments: more angled = more flexible and less stiff End-rounding : each nylon filament is sealed and rounded by heat treatment

Power Toothbrushes: Description
Motion Entire brush head moves as a unit in one type of motion Groups of tufts on the same brush head may move differently Entire brush head moves as a unit, but in different, yet simultaneous motions Different-shaped brush heads move separately, and in different, yet simultaneous motions Speeds: low to high Battery: slower Rechargeable: 3,800-40,000 movements per min

Brush head design Adult: Small and round, conical, or like traditional manual heads Child: Designed for smaller mouth, slower movement Interdental: Designed to fit a standard power brush handle and are similar in shape to manual interdental brushes Filaments: soft, end-rounded nylon Diameter nm Either flat, bi-level or multi-level trims

#7: Fluoride

Fluoride Strong affinity for calcified tissues – 99% located in mineralized tissues Stored in crystal lattice of teeth and bones Highest level is on the tooth surface Pre-Eruptive Stage Deposited during formation of enamel starting at DEJ Incorporated in crystals during mineralization New crystals = fluoroapatite = less soluble then hydroxyapatite Results = shallower grooves, less fissures

Fluoride Post-Eruptive Stage F benefits from topical application only
Uptake most rapid on enamel surface during 1st 2yrs after eruption Topical = fluorhydroxyapatite (Free F ion moves into crystal & forms) Mature enamel reacts with fluoride to primarily form CaF Demin: Calcium Fluoride dissolves 1st, then hydroxyapatite, then fluorhydroxyapatite (NEED TO KNOW THIS ORDER!)

Fluoride: Role in Caries Process
Reacts with hydroxyapatite to form FLUORAPATITE Interferes with bacterial metabolism High concentrations: bactericidal Low concentrations: bacteriostatic Has substantivity: ability to be bound to pellicle and tooth surface and be released over a period of time with retention of potency

Fluoride Therapy Methods Systemic: water, supplements, food
Most efficient from 6mo-14yrs Topical: toothpaste, rinse, in-office

Fluoride Therapy Professional Application
