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.

Protein C is a vitamin K-dependent plasma protein that acts as an anticoagulant. Upon activation, it forms a complex with protein S and inhibits factor Xa and thrombin, thereby preventing excessive clot formation and promoting clot dissolution.

Oral SurgeryThe line of withdrawal is mainly determined by the root pattern. This refers to the path along which a tooth should be removed to avoid interference from surrounding bone and adjacent teeth. Root morphology, including number, size, and curvature, dictates this extraction path.

Crohn/s disease is a type of inflammatory bowel disease (IBD) that can affect any part of the gastrointestinal tract from mouth to anus. A key pathological feature of Crohn/s disease is the presence of non-caseating granulomas (collections of inflammatory cells) in the affected tissue. These granulomas are not typically found in ulcerative colitis, the other major type of IBD.

Oral SurgeryIn children, the healing process for fractures is faster due to the high vascularity and rapid bone turnover in growing tissues. Mandibular fractures in children are typically immobilized for a shorter duration compared to adults, as prolonged immobilization can interfere with the growth of the jaw. Immobilization for 3-4 weeks is generally sufficient to allow proper healing without compromising growth.

Oral PathologyDry socket, also known as alveolar osteitis, is a painful condition that occurs after a tooth extraction when the blood clot fails to form or is dislodged before the wound has a chance to heal. It is an inflammation of the bone (osteitis) in the tooth socket, specifically the alveolar bone, but does not involve an infection of the bone marrow, which would be osteomyelitis.
