Q

What mechansims of adhesion are observed in restoration cements, and give examples of materials for each:
Non-adhesive
Micomechanical bond
Molecular bond

JVD 2018 issue 1, Review of Dental Cements

A

Nonadhesive: cement fills the restoration-tooth gap and holds by engaging in small surface irregularities - I.e. relies on geometric form of tooth preparation - zinc phosphate
Micromechanical: surface irregularities are enhanced through air abrasion or acid etching to provide larger defects – good for materials with large tensile strength – resins, resin-modified GIC
Molecular: bipolar Van der Waals forces and weak chemical bond (material ions bind to Ca of hydroxyapetite) - polycarboxilate, GIC

Q

What is film thickness, and which materials have the relative higher and lower film thickness?

JVD 2018 issue 1, Review of Dental Cements

A

Aka viscosity of the dental cement
Low film thickness → improves setting of crown and decreases marginal discrepancies → reduces plaque accumulation, PD, cement dissolution and caries (humans)
Resins - highest
GIC - lowest

Q

What reaction occurs to set glass ionomer (GIC)?

A

Acid-base reaction
reaction of (a basic) silicate glass powder and an ionomer liquid containing carboxylic acids (or polyacrylic acid). (They form ion cross-linked polymer matrices surrounding glass-reinforcing filler particles).

GIC/composite hybrid) using liquid water-free polyacid monomer in place of polyacrylic acid that leads to a polyacid-modified composite resin. These materials possess a combination of characteristics of composites and glass-ionomers- but are essentially polymer-based composites that have been modified to permit fluoride release from the glass phase.

What does a red ring on a low speed handpiece indicate?

JVD 2019 Issue 3 “The Air-Driven Dental Unit: Form and Function at a Mechanical Level”

A

Red rings indicate a speed increasing handpiece such as a 1:5

which would take a 20 000 RPM motor to an attachment at 100 000 RPM

Q

What handpiece is shown here? What is the RPM for this instrument?

JVD 2019 Issue 3 “The Air-Driven Dental Unit: Form and Function at a Mechanical Level”

A

High speed handpiece
Eqipped with light (arrowhead)

350,000-400,000 RPM

No gear ratios for this instrument

Q

What type of coupling is shown here for the highspeed handpiece? What does each hole connect to?

JVD 2019 Issue 3 “The Air-Driven Dental Unit: Form and Function at a Mechanical Level”

A

(A) Four-hole coupling on a high-speed handpiece.
1. Drive air (smaller of the two large holes)
2. Exhaust air (larger of the two large holes)
3. Water.
4. Chip air - atomizes the water

Q

What are these couplings for the highspeed handpiece? What does 5 and 6 do?

JVD 2019 Issue 3 “The Air-Driven Dental Unit: Form and Function at a Mechanical Level”

A

(B) Five-hole coupling. 5. Light via fiber optics.

(C) Six-hole handpiece. 6. Electricity to a bulb within the handpiece.

Q

In Ringeisen’s 2018 paper “Influence of dental materials on cells of the equine periodontium” what materials were deemed safe and which had adverse effects on PDL fibroblasts?

Ringeisen 2018 EVJ

A

Pericare (oily CaOH suspension) and Provicol (temporary luting cement with CaOH used to affix crowns) had no adverse effects

Calyxl (barium sulphate pulp capping paste) and Honigum (impression material with monophase silicone base and VPS) had severe cytotoxic effects

Calyxl - immediate loss of cell viability
Honigum - increase IL-6 and COX-2 at 24 hrs and decreased viability then
