exam 4-lecture 2 Flashcards
(45 cards)
pad of fibrocartliage or dense fibrous tissue present in some synovial joints (TMJ)
articular disc
what is required before HIV testing?
informed consent by patient and protest counseling
what is the single most important clinical parameter used to asses implant health?
clinical mobility
direct apposition of bone to the implant surface
osseointegration
what results from radiation therapy?
mucositis- painful, erythematous, ulcerated mucosa
xerostomia
rampant decay and candidiasis
osteonecrosis- necrosis of bone
what does HIV infect?
CD4 T-helper lymphocyte for cell mediated immunity and regulating the immune response
what are the three types of immunodeficiency?
brutons disease
digeorges syndrome
severe combined immuneodefiency
with implants, this is infection of the issues around the implant and they are treated same as dentition
bacterial infection… local debride with plastic instruments, topical or systemic antimicrobials and improve patient oral hygiene
what are signs of peri implant disease?
BOP, swelling and erythema
transparent, viscous fluid that is secreted by the synvoial membrane and found in joint cavities
synovial fluid
when are HIV antibodies detectable in blood?
6 weeks after initial infection but some not until 6 months to a year…
time from HIV infection to AIDS is 2-10 years
what are causes of peri implant disease or failure?
poresthetic framework doesn’t precisely fit the abutment
patient demonstrates heavy occlusal function or parafunction
implant has been placed in poorly qualified bone or insufficient quality of bone
position or number of implants placed dose not favor ideal load transmission
what clinical manifestations occur as AIDS related complex?
oral candidiasis, fatigue, weight loss and lymphadenopathy
this is a number of opportunistic diseases… pneumocystis pneumonia, candidiasis and KAPOSI’s sarcoma and hairy leukoplakia
AIDS
this immunodeficiency involves B or T cells
primary immunodeficiency
what bacteria is associated with healthy implants?
nonmotile cocci and rods
these are immunodeficiencies are those that occur as a result of an underlying disorder, AIDS
secondary immunodeficiencies
this type of immunodeficiency is when B cells do not mature and thus a lack of plasma cells throughout the body
brutons disease
what are non surgical treatments of TMD?
pharmacological relief (analgesics, muscle relaxants and pain relievers)
physical therapy (ultrasound, warm heat and spraying and stretching of muscles and jaw exercise)
mandibular splints (mouth guard)
this identified the virus rather than antibody and thereby enables the ID of the infection earlier
polymerase chain reaction (PCR)
this is the articulation between the condyle and the glenoid fossa of the temporal bone
TMJ
this type of immunodefiency is common in infants… most infants die within the first year of life and are vulnerable to all forms of viral, fungal, and bacterial infections
Severe combined immunodeficiency
method of evaluating a joint involving the insertion of small cannulas along with a camera and instruments into a joint
arthroscopy
this was identified in 1983, transmitted through sexual contact with infected blood and infants of infected mothers.
HIV/AIDS
