Oral Medicine
Boggy gums can be seen in both pregnancy and leukaemia.
Pregnancy: Hormonal changes during pregnancy can increase blood flow to the
gums, making them more sensitive, swollen, and prone to bleeding, which can be
described as boggy.
Leukaemia: In some forms of leukaemia, particularly acute myeloid leukaemia,
cancerous cells can infiltrate the gums, leading to swelling, bleeding, and a
boggy appearance.
Polycythaemia: While polycythaemia involves an increase in red blood cells, it
does not typically cause the characteristic boggy gum appearance in the same way
as pregnancy or leukaemia.

State PSC PYQThe viscerocranium, also known as the facial skeleton, is the part of the skull derived from the branchial arches, specifically the first and second arches.It forms the bones of the face and provides attachment for facial muscles.In contrast, the neurocranium (composed of the chondrocranium and desmocranium) forms the protective case around the brain.

Oral medicineEmergency measures for caustic ingestion include endoscopic assessment of degree of damage. Gastric lavage is contraindicated as it may cause further injury. Early endoscopy helps assess severity, guide treatment, and determine prognosis. Other options mentioned are consequences, not treatments.

ProsthodonticsKennedy-Applegate Class VI (missing canine) is probably the first edentulous situation to occur in the dental arch. Canines are often lost due to their prominent position making them susceptible to trauma, or due to orthodontic extractions. This single tooth loss typically occurs before more extensive edentulous patterns develop.

ProsthodonticsThe lingual cusp of a maxillary molar is a supporting cusp. Reduction of a supporting cusp is indicated when there are deflective occlusal contacts in both centric relation and all eccentric movements, to ensure proper occlusion and prevent damage to the tooth or surrounding structures. The goal of selective grinding is to eliminate premature contacts and establish a stable, functional occlusion.
