Gingivitis and Periodontal Disease Flashcards

1
Q

Anatomy of the Periodontium in children compared to adults

A
  1. More red
  2. Lower prevalence of periodontal disease: Junctional epithelium is thicker -> Less permeable to toxins -> More resistant to inflammation
  3. Enhanced rate of progression of periodontal disease

Q

Why is there an enhanced rate of progression of periodontal disease?

A

PDL space is wider, less fibrous, and more vascular. Alveolar bone has larger marrow spaces, greater vascularity and fewer trabeculae

Epidermolysis bullosa, Inflammatory bowel disease

30
Q

Why does Down Syndrome lead to higher susceptibility of periodontal disease?

A
  1. Defective phagocytic function
  2. Possible defect in collagen
  3. Inappropriate regulation of matrix metalloproteinases
  4. Poor OH
31
Q

A
  1. Autosomal recessive
  2. Deficiency in cathepsin C-central coordinator of activation of many proteases in immune cells

33
Q

What is Hypophosphatasia?

A
  1. Deficiency of serum alkaline phosphatase
  2. Increased urinary excretion of phosphoethanolamine and defective bone and tooth mineralization -> Cementum hypoplasia/aplasia -> Premature exfoliation of primary teeth
