Conservative DentistryExplanation: The lingual approach to the distal surface of a canine for Class III amalgam restoration is primarily related to aesthetics. This approach minimizes visibility of the restoration from the facial aspect, which is important for maintaining the natural appearance of the tooth. Aesthetic considerations are particularly significant in anterior teeth, where the visibility of restorations can impact the overall smile and facial aesthetics. While retention, outline form, and resistance are important factors in cavity preparation, the lingual approach is specifically chosen to enhance the aesthetic outcome.

Oral and Maxillofacial SurgeryThe primary function of sutures in oral surgery is to control bleeding and stabilize the tissues involved. By holding the tissue flaps in place, sutures protect the underlying structures and promote proper healing.

Dental Materials
The polyethers are susceptible to dimensional change if immersed for a long time (>10 min) because of their pronounced hydrophilic nature.

NEETMDSThe function of a fixer solution in radiographic film processing is to dissolve and remove the unexposed silver halide crystals from the film emulsion. This process "fixes" the image, making it permanent and preventing the remaining silver from darkening when exposed to light.

Oral PathologyMucous patches are characteristic of secondary syphilis, presenting as multiple, painless, grayish-white plaques with an ulcerated surface on oral mucosa, especially buccal mucosa. The positive VDRL test confirms syphilis. Decubitus ulcers are traumatic, lichen planus shows white striations without ulceration typically, and pemphigus vulgaris shows vesiculobullous lesions rather than plaques.

Explanation: It is usually not associated with a sore mouth: This
statement is true. Denture stomatitis can occur without
significant soreness, although some patients may experience discomfort. The
condition is often asymptomatic, especially in its early stages. It is usually associated with wearing a denture at night:
This statement is true. Wearing dentures continuously,
especially at night, can create a favorable environment for the growth of
Candida species, which is a common cause of denture stomatitis. It is more common in diabetes: This statement is true.
Individuals with diabetes are at a higher risk for infections, including
oral candidiasis, which can lead to denture stomatitis. It is more common in men: This statement is not
true. Denture stomatitis is generally more prevalent in women,
particularly postmenopausal women, due to hormonal changes that can affect
oral mucosa and immune response.

ProsthodonticsShrink-free ceramic (Cerestore) contains organic silicone which gets converted to silica during processing. This transformation occurs without dimensional change, eliminating shrinkage typically associated with ceramic processing. The organic silicone matrix provides shape stability during the conversion process, resulting in precise fit and minimal distortion.
