Hard things Flashcards

1
Q

Discuss and inform the patient about a health diet with particular reference to vitamins and minerals that may influence both a healthy and unhealthy periodontium

A
  • Vitamin D and Calcium deficiencies
  • Vitamin C (Ascorbic Acid) deficiency: associated with changes in the periodontium

Q

Discuss the benefits of ultrasonic instrumentation

A

• Slim diameter tips offer greater access and effective instrumentation options for deep periodontal pockets and furcations
• Ultrasonic instrumentation removes less cementum
1. Irrigation flushes toxins and biofilm from the periodontal pocket and has been shown to increase tissue rate of healing
2. Cavitation destroys bacteria and disrupts biofilm colonization
3. Acoustic micro-streaming is thought to impede biofilm adherence

28
Q

How do you measure tooth mobility?

A
  • Grade I: Slight mobility, up to 1mm of horizontal displacement in a facial-lingual direction
  • Grade II: Moderate mobility, greater than 1 mm but less then 2 mm of horizontal displacement in a facial-lingual direction
  • Grade III: Severe mobility: greater then 2 mm of displacement in a facial-lingual direction or vertical displacement (tooth depressible in the socket)
29
Q

Describe the role of ultrasonic use

A
  1. Arrest infection and maintain a healthy periodontium by removing bacteria
