Principles Of Instrumentation Flashcards
Define root planning
Removal of dental plaque, calculus and then smoothing of root surfaces, removing dentine or cementum
(Historical)
What is curettage
Removal of the soft tissue lining of the periodontal pocket with a curette
(Historical)
What is NSPT
Non surgical periodontal therapy
When would you use prophylaxis
Less than 10% bleeding in mouth
Healthy gingival tissue
Minimal plaque and no supra gingival calculus.
What is known as the first step therapy
Supra professional mechanical plaque removal (PMPR)
When would you carry out supra PMPR and what does it involve
Bleeding 10-30%
Personalised oral hygiene advice
Patient education and prevent advice
Support in controlling risk factors
Supra gingival biofilm removal
What is the second step therapy?
Subgingival professional mechanical plaque removal (PMPR)
What’s the aim of subgingival PMPR
To remove endotoxins (biofilm, calculus) sitting on cementum to control bacterial load, reduce inflammation and bleeding, whilst maintaining structure of tooth
When would you perform subgingival PMPR
Periodontitis patients
What is phase of maintaining a periodontal stability?
Supportive periodontal therapy (SPT)
How often are supportive periodontal therapy appointments?
3-4 monthly
What consists of supportive periodontal therapy
Periodontal revaluation
Risk assessment
Oral hygiene instruction
Supra and sub gingival professional mechanical plaque removal.
What are the principles of instrumentation
Patient compliance
Accessibility
Visibility, illumination, retraction
Condition of instruments
Clean field
Operator action (stabilisation, action, stroke)
Objectives of non surgical periodontal instrumentation
Remove and disrupt biofilm
Remove calculus
Eliminate or reduce inflammation
Promote soft tissue attachment
Present optimal tooth surface for host
Steps to be taken before treating patient
Inform patient of diagnosis
Why they have the condition
What are their risk factors
What treatment alternatives is there
