Exam 1: Chapter 11,12&13 Flashcards
mandibular movement toward the midline; the mediotrusive side moves toward midline in function
mediotrusion
what are active agents in triclosan toothpastes been shown to reduce plaque?
zinc citrate or copolymer of methoxyethlyene and maleic acid
the maximum intercuspation of the mand. and max. teeth, also called centric occlusion and habitual occlusion
intercuspal position
abnormal movement and can describe masticatory muscle incoordination or spasm
dyskinesia
which tooth brushing method is focused at the gingival margin?
bass method
this is a quaternary ammonium compound in mouthwashes?
cetylpyridinium
some also contain domiphen bromide
what is a disadvantage of the scrub brushing technique?
it has been associated with gingival recession
pain in the muscle
myalgia
this is a phenolic compound available without a prescription in toothpaste formulations with antiplaque, anticalculus, and antigingivitis agent..
triclosan
what happens in the phase 4 therapy?
evaluation of patients oral hygiene
smoking cessation
treatment depends on the condition of periodontium
relationship of form and function
morphofunction
what is the most effective antibacterial agent available?
chlorhexidine
root smoothness achieves all of the following except one.. which one is the exception?
delays tissue attachment enhances self cleaning promotes healing retards plaque formation sooths irritated tissues
(delays tissue attachment)
attachment gain after nonsurgical therapy should be measured carefully because inflamed tissues may not provide accurate reading
both are correct and related
these reduce the bacterial load and enhance the hosts defense to the infectious oral pathogens in chronic periodontitis, aggressive perio and perio
antibiotics
the concept of periodontal pathogens associated with different types of periodontal disease called
specific plaque hypothesis
plaque control for perio pts. include tooth brushing and use of an appropriate interdental aid. All periodontal pts. must use dental floss
the first statement is true, second is false
this is an effect enzyme suppressor including collegenase
periostat
a number of clinical trials have proved this shows no additional benefit to healing compared with scaling and root planing alone
curretage
this forces water between the teeth with a single or multiple jets of pulsed beads of water
supragingival irrigation
why is penicillin a type of antibiotic is not considered effective in perio diseases?
because the pathogens are resistant to penicillin..
enzymes produced by periodontal pathogens tend to break down thepeniclliin
the term that best describes heavy occlusal forces that have caused injury to tissues and bone in a normal periodontium
primary traumatic occlusion
dental hygiene support for home care for perio patient includes
demonstrating the necessary techniques in the office
understanding individual pt. likes and dislikes relating to oral care
ongoing encouragement
when is healing greatest for nonsurgical perio therapy?
3-6 weeks
treatment that alters the occlusal contacts or mandibular positin of the jaw
occlusal therapy
the antimicrobial minocycline is commonly used for antimicrobial agents for periodontal disease..what commercial agent, product form and how Is it placed?
arestin
microspheres
placed with syringe biodegrades
this is the simplest brushing technique and does not focus cleaning at the gingival margin
scrub method
this technique is beneficial for patients with orthodontics because the orientation of the bristles in this technique effectively removes debris trapped by brackets and wires
charters
as it ages, how does supragingival plaque become dominated?
by gram negative microbial species
what are some examples of antimicrobial irrigants?
- 12% chlorhexidine
- 4% stannous fluoride
- 05% povidone fluoride
the term for removal of inflamed soft tissue wall lining of perio pocket is
gingival curettage
movement of the mandible outside the range of function
parafunction
tooth contact that does not allow the teeth to achieve stable interdigitation; also called supracontact
interference
this antibiotic is successful of certain periodontal diseases and can accumulate high concentrations in the gingival sulcus
tetracycline (minocycline or doxycycline)
what are the phases of phase 1 or intial therapy?
ER care; relief of sudden symptoms
oral hygiene instructions
nutritional counseling
correction of inadequate restorations
periodontal debridement
antimicrobial therapy
systemic antibiotics
fluoride applications
smoking cessation
minor orthodontic movement
extraction of hopeless teeth
reevaluation of initial therapy
what is the normal mandibular side to side movement?
8 mm
clamping and forcing the teeth together without grinding
clenching
what are the four symptoms commonly reported in patients with TMDS?
pain and tenderness in muscles of mastication
pain and tenderness in TMJ
painful clicking of the joint during function
limitation of mandibular motion
pain in the joint structure
arthalgia
cracking or snapping noises in the TMJ because of disk and condyle incoordination; can occur in one or both joints
clicking
involuntary contraction of a muscle or muscles, usually a painful interfering with function
spasm
to provide the most beneficial effects, chemical antiplaque agent should demonstrate several properties
antiplaque action
substantivty
low toxicity and non irritating
low permeability
what are lasers used for?
in periodontics- used for removing calculus, subgingival bacterial flora, sterilizing periodontal pockets, enhancing root instrumentation and performing perio surgery
what are the four primary symptoms of TMDS?
muscle pain, jaw pain, clicking, and limitation of motion
who is bruxism most common with?
children ages 3-12 yrs of age
air powder polishing works by application of a mechanical abrasion of slurry of
sodium bicarbonate and water
myalgia is best described as
pain in the muscles
grinding or gnashing of the teeth usually during sleep; an oral habit that can cause periodontal injury and pain and discomfort in the jaw
bruxism
what state is the oral cavity in when talking, chewing and swallowing?
dynamic
all of the following are characteristics of chlorhexadine except..
substantivity
anticalculus agent
taste perversion
ada approved for gingivitis treatment
(Anti calculus agent)
what are the short term goals of evaluation?
clean and smooth root surfaces
these are repetitive masticatory activities outside the normal range of function
oral habits
this technique involves brushing the teeth the way that they grow
roll
what are side effects of chlorhexidine?
dark brown staining, increased supragingival calculus and altered taste
what is the long term goal of calculus and biofilm removal?
regular removal of new deposits at subsequent visits
what is metronidazole useful for?
patient who have ANUG or HIV
inflammation in a muscle
