s10-finals-Care and Maintainance Flashcards
(25 cards)
What is the minimum daily frequency recommended for effective plaque removal with a manual toothbrush?
At least once daily.
For patients with limited dexterity, which type of toothbrush is advised?
Automatic (powered) toothbrush.
How do interproximal brush color codes correspond to gap sizes?
Each color indicates a specific diameter, e.g.:
- pink 0.4 mm
- orange 0.45 mm,
- red 0.5 mm,
- blue 0.6 mm
- yellow 0.7 mm
- green 0.8 mm
- violet 1.1 mm
- grey 1.3 mm
- black 1.5 mm.
Why is dental floss essential in addition to brushing?
Brushing alone doesn’t adequately remove plaque from proximal surfaces.
When and why is a floss threader needed?
When spaces are limited or under fixed prostheses, to guide floss through tight areas.
What features make super floss particularly useful around FPDs?
It has stiffened ends for threading, spongy sections for cleansing under margins, and regular floss segments.
What material is dental cleansing tape made from, and what dual function does it serve?
Made of Hytrel elastomer; it flosses while providing polishing action.
How do oral irrigating devices assist in plaque control under fixed restorations?
They deliver pulsating or steady water streams to dislodge debris under FPDs and between crowns.
Approximately how many strokes per minute does a typical Waterpik provide?
Around 10,000 gentle strokes per minute.
What is the primary purpose of interdental cleansing devices like wood or rubber points?
To remove food particles and simulate gingival tissue stimulation.
Why should chewing gum be avoided immediately after crown and bridge work?
It can adhere to resin margins and exert hydraulic pressure that drives debris deeper.
At what concentration is chlorhexidine digluconate used for short-term plaque inhibition?
0.2% rinse twice daily.
What complication around implants is addressed by meticulous hygiene?
Prevention of mucositis and peri-implantitis and associated bone loss.
How often should patients with implant-retained restorations be professionally reviewed?
Every six months.
Which dietary change most directly reduces bacterial proliferation and caries risk?
Decreasing intake of sucrose and replacing with non-cariogenic substitutes.
What effect do processed foods have on oral health in fixed prosthodontics patients?
They increase plaque accumulation and caries potential.
Why should soft drink consumption be limited post-cementation?
High sugar content promotes caries, acids etch enamel, and increase cement solubility.
How can bruxism jeopardize fixed restorations?
Muscle pressure can cause tooth movement and fracture of restorations.
What is reverse swallowing and why is it problematic for prostheses?
Tongue thrust against teeth during swallowing, leading to occlusal and prosthetic misalignment.
How does habitual pipe clenching affect crown and bridge longevity?
Continuous pressure risks loosening or fracturing cemented restorations.
What stain-producing habit can affect the aesthetics of fixed prostheses?
Smoking.
What is the recommended interval for routine recall visits after cementation?
Every six months.
During a post-cementation visit after 7–10 days, what key checks should be performed?
Cement remnants in sulcus, occlusal contacts, and minor tooth shifts needing adjustment.
Which diagnostic tool is convenient for assessing pulp vitality under partial coverage restorations?
Electric pulp tester.
