SOLUTION Stress is the force applied per unit area while strain can be defined as the internal distortion per unit area.
Stress and strain are inter-related terms as stress is an external force acting upon a body while strain is the resultant of stress on that body.
Strain can be expressed in the form of a change in either the external dimension or internal energy of the body.

NEETMDSFor diagnosing proximal caries in a deciduous molar, especially when the extent of decay needs assessment, a periapical (IOPA) radiograph is the standard and first line of investigation. This imaging technique allows visualization of the interproximal surface and the pulp status, which is crucial for treatment planning. Electric pulp testing, thermal testing, and test cavities are typically used to assess pulp vitality in more complex cases or when the diagnosis is uncertain, not as a primary diagnostic tool for proximal caries.

Diabetic neuropathy leads to loss of protective sensation, allowing for unnoticed trauma and subsequent ulceration. Abnormal foot biomechanics can cause increased plantar pressure and foot deformities such as hammertoes or calluses that may progress to ulcers. PAD reduces blood flow to the feet, impairing the healing process and making infection more likely. Poor wound healing is a direct consequence of both neuropathy and vascular compromise.

RadiologyThe recommended time for developing an X-ray film at a solution temperature of 20 degrees Celsius is 4.5 minutes. This time may vary slightly depending on the specific developing solution and film type, but 4.5 minutes is the commonly suggested time to ensure proper exposure and development.
