Osteitis fibrosa cystica is a characteristic bone change seen in hyperparathyroidism. It results from excessive osteoclastic activity and is characterized by the replacement of normal bone marrow with fibrous tissue and cyst-like spaces.

Primary prevention aims to stop disease before it starts. Pit and fissure sealants protect tooth surfaces and prevent caries formation.
Serial extraction and scaling and root planning are examples of secondary or tertiary prevention, as they involve treatment after a condition (malocclusion or periodontal disease) has already started.
Fluoride use on incipient caries is also secondary prevention as it aims to halt the progression of an already existing early lesion.

In muscular dystrophy, there is ongoing muscle fiber destruction and regeneration, which leads to the release of muscle enzymes into the bloodstream. CK-3 is the muscle-specific isoenzyme that is most commonly elevated in muscular dystrophies, indicating damage to skeletal muscles.

Oral PathologyEpiphora (excessive tearing) is an associated symptom of periodic migrainous neuralgia (cluster headache). Cluster headaches are accompanied by autonomic symptoms including lacrimation, nasal congestion, and conjunctival injection on the affected side. Trigeminal neuralgia, acute periodontitis, and ptyalism are not typically associated with excessive tearing.

ProsthodonticsBefore altering the abutment contour for clasp retention, it is essential to establish the guiding planes. This is done by disking the proximal surfaces of the abutment teeth to create a flat, smooth surface that will guide the RPD during insertion and removal. Once the guiding planes are in place, the contour of the abutment can be altered to accommodate the placement of the retentive elements such as rests and minor connectors.

Oral SurgeryA bilateral inferior alveolar nerve block is not inherently contraindicated. It is commonly performed in cases requiring surgery on both sides of the mandible. However, it should be done with caution in patients with certain medical conditions or anatomical variations that could increase the risk of complications. It is important to assess each patient individually before administering the block.
