Which sentence is correct?

• Anchorage is refer to the resistance to unwanted tooth movement

• Anchorage can be applied only in oral cavity

• Teeth always provide the best source for Anchorage

• All are correct

Which sentence is correct?

• Anchorage loss may not occur when excessive force is applied because this causes hyalinization of the periodontal ligament.

• Anchorage loss may occur when excessive force is applied because this causes hyalinization of the periodontal ligament.

• The best way to have maximum anchorage is to have compound anchorage

• All are correct

Which sentence is correct ?

• Orthodontic movement would not be possible without the ability of the alveolar bone to remodel

• The cell of the periodontal ligament are responsible for the bone remodelling and, hence, tooth movement.

• The osteoblast is the bone forming cell and is also responsible for the recruitment and activation of osteoclasts (bone- resorbing cells)

• All are correct

Which sentence is correct?

• A number of different growth factors and signaling molecules are now known to be intimately involved in bone removal and formation during orthodontic tooth movement.

• A number of different growth factors and signalling molecules are now known to be intimately involved in bone formation during orthodontic tooth movement.

• A number of different growth factors and signalling molecules are now known to be intimately involved in bone removal during orthodontic tooth movement.

• A number of different growth factors and signalling molecules are now known to be intimately involved in bone removal, formation, inflammation during orthodontic tooth movement.
