ProsthodonticsIn anterior teeth, "rests" are ideally prepared and located on the lingual surfaces. This is because the lingual surfaces provide better support for the denture and distribute the occlusal forces more evenly across the palatal mucosa, reducing the risk of denture movement and discomfort.

Hypothyroidism decreases metabolic activity, leading to a decreased Basal Metabolic Rate (BMR).

PhysiologyThe macula densa is found in the distal convoluted tubule, where it senses sodium chloride concentration and helps regulate glomerular filtration rate.

Conservative DentistryDuring cavity preparation, the most common area for exposure is a Class V cavity in the first premolar. A Class V cavity is a five-sided cavity that involves the gingival margin of the tooth and the proximal surface. These cavities are particularly prone to exposure because the gingival tissue in this region can be thin, and the proximity to the bone can lead to inadvertent damage during the preparation process.

PedodonticsArkansas stone is lubricated with light mineral oil to prevent heat build-up, remove metal particles, and prevent it from drying up.

Awake fibreoptic intubation is preferred for skull base fractures to avoid accidental intracranial placement of the tube (a risk with blind nasal intubation) and to manage potential cervical spine injuries.

NEETMDSRoot canal morphology can be highly variable and complex. Clinically, it is best practice to assume the presence of additional canals until proven otherwise, as failure to locate and clean all canals can lead to endodontic failure. Canals often branch and can have multiple systems within a single root.
