Oral SurgeryThe reddish patch of median rhomboid glossitis lacks filiform papillae, which are the most numerous papillae covering the anterior two-thirds of the tongue's dorsal surface. These papillae are highly keratinized and are responsible for the tongue's normal white-pink appearance. The absence of these keratinized papillae makes the affected area appear redder and smoother, standing out distinctly from the surrounding normal tongue tissue.

The typical force applied with a condenser during restorative procedures is 3.75 pounds for a 0.5 mm diameter nib, 8.43 pounds for a 0.75 mm diameter, and 15 pounds for a 1 mm diameter nib. The force is applied parallel to the long axis of the instrument shaft.

Oral PathologyThe prognosis of epidermoid carcinoma (squamous cell carcinoma) is generally considered least favorable in the posterior lateral border of the tongue compared to the lower lip, upper lip, or hard palate because the tongue has a rich lymphatic supply, leading to a higher risk of early metastasis to regional lymph nodes.

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.
