RadiologyTo localize a supernumerary or an impacted tooth and determine its exact relationship to the other teeth, the most effective radiographs would be two or more periapical views at different angles and an occlusal view.

Subgingival curettage involves removing the inflamed soft tissue lateral to the periodontal pocket wall. It is indicated in cases of oedematous gingivitis because the inflamed, soft, and retractable tissue is easier to remove and responds favorably to this procedure.
In contrast, fibrotic gingivitis involves dense, firm tissue that is not easily removed by curettage, and
infrabony pockets require more advanced procedures like surgical flap access for effective treatment.

The RAS gene produces a
protein (Ras) that acts as a molecular switch in cell signaling
pathways, typically promoting cell growth and proliferation when
bound to GTP (guanosine triphosphate). To
turn this signal off, the Ras protein must hydrolyze its bound GTP
to GDP (guanosine diphosphate). This
hydrolysis is significantly accelerated by GTPase activating
proteins (GAPs), which inhibit the active state of the Ras
protein by promoting its deactivation.

•In two ways the overall pattern of growth of the mandible can be represented .It will depend on the frame of reference if both are correct. The chin moves downward and forward if the cranium is the reference area.
On the other hand, it becomes apparent that the principal sites of growth of the mandible are the posterior surface of the ramus and the condylar and coronoid processes if data from vital staining experiments are examined. Along the anterior part of the mandible there is little change
• The chin is almost inactive as a growth site. As the actual growth occurs at the mandibular condyle and along the posterior surface of the ramus it is translated downward and forward. By periosteal apposition of bone on its posterior surface the body of the mandible grows longer , at the condyle accompanied by surface remodeling while the ramus grows higher by endochondral replacement
• Conceptually,wiht is correct to view the mandible as being translated downward and forward,though at the same time it increases in size by growing upward and backward. As the bone moves downward the translation occurs largely. As the bone moves downward and forward along with the soft tissues in which it is embedded the translation occurs largely

Oral SurgeryLe Fort III fractures are characterized by a fracture pattern that involves the separation of the facial skeleton from the cranial base. This type of fracture typically extends across the orbits and involves the zygomatic arches, leading to significant facial disfigurement and potential complications.

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..
