what is non surgical perio tx

all measures, non surgical and educational used to control gingivitis and periodontitis

what are examples of NSPT

dental biofilm removal and control,supra and sub scaling, root debridement, adjunctive therapies, pt education

what is needed in the treatment of perio disease

effective removal of plaque, calc and associated endotoxins so that perio healing can occur in the oral enviroment

what indicates NSPT

- plaque associated gingivitis - slight perio - moderate perio (for most patients) - severe chronic perio (for a few patietns)

what are goals in perio therapy

control bacterial challenge (remove calc, plaque, homecare) minimize impact of systemic risk factors minimize local risk factors stabilize attachment level

what is scaling

instrumentation of the crown or root surfaces to remove plaque calc or stain

what is root planing

removing cementum or surface dentin that is rough impregnated with calc or contaminated with toxins or microorganisms

what is SC/RP

-complete removal of plaque and calc -smooth glassy root -often resulted in overinstrumentation -

what does root debridement do

treats preio as an infection or disease- is theraputic

what does SRP do

mechanical removal focued on plaque and calc

what is debridement

removal of disruption of bacterial plaque needed to reestablish perio health and restore balance

what is gross scaling

aka gross debridement or preliminary partial scaling removal of most accessable calc

what is the code for perio scaling and root planing for 4 or more teeth? 1-3 teeth?

4341 | 4342

is SRP prophylactic or theraputic

theraputic

what is full mouth debridement

gross removal of plaque and calc that interferes with ability of dentist to do a eval

what are the 3 steps of NSPD tx

- full mouth disinfection or partial mouth - re eval appt - perio maintenance

what is full mouth disinfection? partial?

- 2, 2 hr appts. 24-48 hrs apart | - 2-4, 1 hr appts in a 2 week time span

when should the reevaluation appointment be

4-6 weeks after instrumentation has been completed

What are signs of non reponsive sites

continued loss of attachment clinical signs of inflammation bleeding on probing

when should you refer

- moderate perio if cant be controlled with NSPT - severe or agressive perio - perio conditions that continue to decline

What is as important as intial therapy

homecare, talk to pt at every appointment

what is informed consent

patients voluntary consent to treatment after they have been informed of perio disease, tx, risks benefits ect

what is written consent

- formal consent form to document consent process - pt dates and signs form - dentist and witness sign - copy in chart, copy to pt

in verbal consent what do you do

record in chart

what stroke is used for a hoe? chisel

pulling, pushing

what is not a goal fo rNSPT

customize homecare instructions for pt

successful perio debride always results in complete removal of cementum from exposed root surface

false

full mouth disinfection is

perio debride completed in 2 appts within 24 hr period

what is the end point of instrumentation in NSPT

the root surface and pocket are in a state that healing can take place

when should the re-eval appt occur

4-6 weeks from end of NSPT

what is the active tip area of ultrasonic

last 2-4 mm

1 mm of wear on ultrasonic results in

____ loss of efficency
