Which of the following is not a function of the periodontal ligament?

Contains nerve fibres than transmit tactile pressure

Blood vessels to nourish enamel and alveolar bone

Provides cementoblasts to produce cementum throughout tooth’s life

Osteoblasts that maintain bone tissue of tooth socket

Induction of tooth movement occurs by which four stages (in which correct order)?

Cell activation and differentiation, cell strain, matrix stain and fluid flow, remodelling

Matrix strain and fluid flow, cell strain, cell activation and differentiation, remodelling

Remodelling, cell strain, cell activation and differentiation, remodelling

Cell strain, remodelling, matrix strain and flow, cell activation and differentiation

Which words fills in the gap from the image below?

Strain of PDL cells: osteoblasts and fibroblasts

Activation of osteoclasts

Initiation of differentiation

Preparation of osteogenic cells

Which word fills in the gap of the blanked out box?

Absorption of alveolar bone

PDL strain

ECM synthesis

Breakdown of proteins

Which word fills in the gap of the blanked out box?

Bone recession

Bone remodelling

PDL fixation

Loss of attachment

Which of the following does NOT occur during the cell activation and differentiation stage?

New extracellular matrix is formed during remodelling when collagen increases

Transforming growth factor, cathepsins and interleukin-1 beta found in the gingival crevicular fluid of teeth and help synthesise extracellular matrix

Nitric oxide promotes osteoblast activity at apposition side so bone is formed

Bone formation at the apposition side is through extracellular matrix production and mineralisation

During the cell strain phase

Direct deformation of PDL cells via strain of cell matrix attachment

Protein kinases initiate intracellular signalling pathways

PDL osteoblasts release signalling molecules

Extracellular matrix is degraded

Which of the following does not occur at the resorption side during the remodelling stage?

PDL is being formed to maintain the tooth's support

Osteoclasts attach to alveolar bone via integrins

Type 1 collagen is replaced by Type 3 connective tissue so movement occurs

PDL and alveolar bone do not breakdown

Which of the following does not occur at the apposition side during the remodelling stage-?

Collagen production increases to fix tooth back into place

Osteoclasts destroy bone to allow tooth to move

New PDL fibres become trapped in new alveolar bone and are termed Sharpey's fibres

PDL fibres are stretched to move the teeth through the bone

Which substances are involved in cell activation and differentiation?

RANKL, osteoprotegerin, colony-stimulating factor

RANK, prostaglandins, modafinil

Osteocalcin, alkaline phosphatase, collagenous proteins

Osteoprotegerin, alkaline phosphatase, benzodiazepine

During cell activation and cell differentiation, - made by - activate - on - side to form bone

Chemokines; osteoblasts; PDL osteoclasts; apposition

Cytokines; osteoblasts; alveolar bone cells; apposition

Cytokines; osteocytes; PDL osteoblast precursors; resoprtion

Chemokines; osteoclasts; alveolar bone cells; resorption

During matrix strain and fluid flow, stretching of the collagen fibres occurs at the - side?

Resorption side

Apposition side

How to osteoclasts attach to the bone surface during cell differentiation and activation?

Osteoblasts degrade the non-mineralised layer of the osteoid

Osteoblasts create an adhesion layer for molecules to attach

Surface tension increases as the ligament is stretched on one side

Vesicles carrying adhesion molecules breakdown and release factors
