Oral SurgeryFree margin should NOT be broader than the base in mucoperiosteal flap design. The base should be broader than the free margin to ensure adequate blood supply. A narrow base compromises vascularization and can lead to flap necrosis.

Oral SurgeryAnterior to lateral pterygoid plate. In the extraoral maxillary nerve block, the needle is inserted at the posterior aspect of the condylar neck and directed anteriorly to target the pterygomandibular space, which contains the maxillary nerve and its branches. This technique is used to anesthetize the molars and premolars of the upper jaw and is also known as the Vazirani-Akinosi technique.

Explanation: In bilateral balanced occlusion, if the incisal
guidance is steep, it is necessary to create a compensating curve that is also
steep to maintain balanced occlusion during lateral movements. This helps to
ensure that the occlusal contacts remain balanced and stable, preventing tipping
or dislodgment of the denture during function. The other options do not
adequately address the need for balance in occlusion.

Oral SurgeryAnalgesics should be administered before the effect of local anesthesia wears off (preemptive analgesia). This approach prevents the establishment of pain pathways and provides better pain control than waiting for pain to occur. It ensures patient comfort during the transition from anesthetic effect.

State PSC PYQChronic hyperplastic candidiasis is distinct because it forms firm, persistent white plaques that cannot be easily wiped off with a gauze. Crucially, these lesions have the potential for epithelial dysplasia and malignant transformation, which is a key differentiating feature from other more common, easily removable forms of oral candidiasis like pseudomembranous candidiasis..
