Perio Final Flashcards
(269 cards)
Most common chromosomal anomaly in humans, affecting about 5,000 babies born each year and more than 350,000 people in the United States
Trisomy 21
Genetic condition caused by an extra chromosome of the 21st chromosome (47 instead of 46)
Trisomy 21
Generalized early periodontitis, begins in the deciduous dentition and continues in the adult dentition
Trisomy 21
Prevalence and severity of perio is extremely high when compared to either their siblings or other mentally challenged individuals
Trisomy 21
Where are the most frequent sites of perio destruction in pts with Trisomy 21?
Molars
Incisors
The roots of the lower incisors are characteristically short which, in combination with the loss of bone, predisposes to premature tooth loss
Trisomy 21
Delayed eruption of both primary/permanent dentitions, microdontia, macroglossia
Trisomy 21
Molecular biology research has underlined the
important role of several cell-cell adhesion
receptors on the neutrophil surface; emphasizing
that defects in numbers of these receptors may
lead to increased susceptibility to infectious
disease
Leukocyte-adhesin deficiency syndrome
Associated w/ perio, oral ulcers, and chronic necrotic skin lesions
Leukocyte-adhesin deficiency syndrome
An inborn error of metabolism with highly variable clinical severity caused by loss-of-function mutations in the gene encoding tissue nonspecific alkaline phosphatase (TNSALP)
Hypophosphatasia (HPP)
Decreased serum alkaline phosphatase and severe loss of alveolar bone and premature loss of the deciduous teeth, particularly in the anterior region
Hypophosphatasia (HPP)
Mutated Gene CTSC
Papillon-Lefevre syndrome
Encodes for cathepsin C, key activator of serine proteases in immune cells
Papillon-Lefevre syndrome
Autosomal recessive, characterized by the presence of hyperkeratotic skin lesions
Papillon-Lefevre syndrome
Exhibits diffuse palmar and plantar keratosis
Papillon-Lefevre syndrome
Severe generalized periodontitis, commonly before puberty with early loss of deciduous and permanent teeth
Papillon-Lefevre syndrome
Teeth are lost in order of eruption and as yet there is no general agreement on the success of dental therapy
Papillon-Lefevre syndrome
Associated with complete edentulism early in life
Papillon-Lefevre syndrome
Chemotaxis association
Papillon-Lefevre syndrome
LYST gene lysosomal trafficking regulator protein affecting phagocytosis
Chediak-Higashi syndrome
Autosomal recessive trait associated with severe periodontitis
Chediak-Higashi syndrome
Neutrophil chemotaxis and bactericidal functions are abnormal in these patients
Chediak-Higashi syndrome
Immune system abnormalities, bleeding abnormalities, and multiple infections
Chediak-Higashi syndrome
C1R and C1S serine proteases of the complement cascade
Ehrlers-Danlos syndrome
