Question 1

What is the PEDDS

Answer 1

Wang group
P = Primary wound closure
E = Etiology
D = Debridement
D = Decontamination
S = Stability of Wound

Question 2

What is the average time of decontaminating the implant surfaces in implantoplasty?

Answer 2

Costa-Berenguer
10 minutes

Question 3

By what % does Er:YAG laser remove bacteria from the peri-implant surface?

Answer 3

Huang
84.1% of bacteria removed
(Using 100 mJ/pulse setting on SLA titanium surface)

Question 4

What is the wavelength of diode lasers?

Answer 4

810 and 980 nm

Question 5

Is laser effective in treatment of human peri-implantitis?

Answer 5

No -
Papadopoulos = used diode lasers. Found NSSD
Yayli = Used Er,Cr:YSGG (“Waterlaser”) and Diode lasers. Found NSSD
Strauss = NSSD

Question 6

What is the commercial name for Er,Cr:YSGG laser?

Answer 6

Waterlase

Question 7

What are the wavelengths of CO2 and Nd:YAG lasers?

Answer 7

CO2 lasers = 9600 - 10,600 nm.

Nd:YAG lasers = 1064 nm.

Diode = 810-920 nm

Dr. Wang says: Diode is not as effective; CO2 is much more effective

Question 8

How effective is electrolytic cleaning of peri-implantitis implants?

Answer 8

Schlee ‘19
50% of cases = achieved “re-osseointegration”

Question 9

How does Ti brush compare to ultrasonics with 3% H2O2 in peri-implantitis disinfection?

Answer 9

Monje ‘22 IJOI
Ti brush success rate: 66.7%
* PD reduction: 2.84mm
* R. bone fill: 2.61
Ultrasonic + H2O2: 23.1%
* PD reduction: 2.19mm
* R. bone fill: 1.17mm

Question 10

How do ti brushes compare to the plastic curettes and air abrasion?

Answer 10

Monje ‘22 IJOI
Success rates of implants decontaminated:
Ti brushes: 33%
Plastic curettes: 22%
Air abrasion: 27%
