The sparing of the forehead indicates an Upper Motor Neuron (UMN) lesion. This is because the upper face receives bilateral innervation from the motor cortex. A stroke typically causes UMN facial palsy (contralateral lower face only), whereas Bell's palsy is a Lower Motor Neuron (LMN) lesion affecting the entire half of the face including the forehead.

EndodonticsReplacement resorption results in ankylosis. This process involves: 1) Loss of periodontal ligament due to trauma or infection, 2) Direct contact between root surface and alveolar bone, 3) Osteoblasts lay down bone tissue directly on root surface, 4) Root dentin is gradually replaced by bone tissue, 5) Tooth becomes fused to surrounding bone (ankylosis). This condition is irreversible and eventually leads to complete replacement of root structure with bone. Pain and periapical abscess are not typical consequences of replacement resorption itself.
