Physiology
Answer: 4) The ionic gradients involved in RMP generation are the same in both neurons and muscle cells
Explanation: The RMP in both neurons and muscle cells is generated primarily by the difference in potassium ion concentration across the cell membrane. The concentration gradient of K+ is maintained by the sodium-potassium ATPase pump, which pumps 3 Na+ ions out and 2 K+ ions into the cell, contributing to the negative resting membrane potential.

Midline diastema is a common condition involving a gap between the two upper
front teeth.
Various orthodontic techniques and appliances can be used to close this space,
which typically involves applying controlled force to move the teeth closer
together.
(a) Lingual bow with inter tooth traction: A lingual bow is an orthodontic
appliance that can be used with traction (force) between teeth to close a
diastema.
(b) Hawley's appliance with finger springs: A Hawley appliance is a type of
removable retainer often used in orthodontics.
It can be modified with finger springs to apply gentle pressure and move teeth,
including closing a diastema.
(c) Bonding tooth and inter tooth elastics: Bonding brackets or buttons to the
teeth and using intermaxillary elastics (rubber bands) is a standard method to
apply force and close gaps.
(d) Use of steel ligature directly on tooth: Applying a steel ligature wire
directly around a tooth to move it would likely cause uncontrolled tilting of
the tooth and potential damage to the tooth and surrounding tissues, rather than
a proper, controlled correction of the diastema.It is not a standard or safe
method for this purpose.

ProsthodonticsA complete denture wearing patient complains of tingling sensation in the lower premolar region. The ridges are resorbed. The most possible explanation is pressure on the mental foramen due to ridge resorption.

1) Laterally positioned graft: This technique is used when there is a loss of
interdental papilla, which may occur due to periodontal disease or trauma.
2) Free gingival graft: This involves the transfer of a piece of tissue from the
palate to the affected area to cover the exposed root surface and increase the
zone of attached gingival tissue.
3) Coronally displaced graft: This technique involves moving the existing
gingival tissue coronally over the exposed root to cover it.
4) Maintenance and recall visits: After the resolution of inflammation through
scaling and root planing, if the recession is minimal and the tooth is not at
risk of further damage, regular maintenance and recall visits may be sufficient
to monitor the area.
Since the question mentions that the tooth is normally placed and the issue is
resolved after scaling and root planing, the correct answer is 4) Maintenance
and recall visits to ensure the area remains healthy and monitor for any
recurrence of recession.
