Oral Manifestations of HIV Infection and AIDS
Acquired Immunodeficiency Syndrome (AIDS) represents the advanced stage of infection caused by the Human Immunodeficiency Virus (HIV). HIV is a retrovirus that primarily targets CD4+ T-helper lymphocytes, progressively weakening the immune system. As immune function deteriorates, patients become increasingly susceptible to opportunistic infections, unusual malignancies, and systemic complications. Because the oral cavity contains a complex […]
Oral Manifestations of Neurological Disease
Neurological diseases frequently produce signs and symptoms within the oral and maxillofacial region. Because the mouth, face, and jaws are richly supplied by cranial nerves—especially the trigeminal (CN V) and facial (CN VII) nerves—neurological disorders often present with sensory, motor, or autonomic disturbances in these areas. Careful examination of the cranial nerves is therefore essential […]
Oral Manifestations of Endocrine Disease
Endocrine disorders frequently produce systemic effects because hormones regulate growth, metabolism, calcium balance, immune responses, and tissue integrity. Since the oral cavity contains rapidly dividing tissues, bone, mucosa, salivary glands, and a rich vascular supply, it is often affected in endocrine disease. In some cases, oral findings may even provide the first clinical clue to […]
Oral Manifestations of Haematological Disease
Haematological diseases frequently present with oral signs and symptoms. In some cases, oral findings are the earliest clinical indicators of systemic blood disorders. Because the oral mucosa has a high cell turnover rate and is richly vascularized, it is particularly sensitive to abnormalities in red blood cells, white blood cells, platelets, and plasma proteins. Recognition […]
Oral Manifestations of Gastrointestinal Disease
The oral cavity frequently reflects systemic disease, and disorders of the gastrointestinal (GI) tract are particularly notable for producing oral signs and symptoms. In some patients, oral lesions may precede intestinal manifestations, making dental practitioners pivotal in early diagnosis. The conditions most commonly associated with oral findings include coeliac disease, ulcerative colitis, Crohn’s disease, orofacial […]
Facial Pain
Facial pain is a common but complex clinical problem encountered in medical and dental practice. Pain itself is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. It is a subjective phenomenon influenced by biological, psychological, and social factors, and its assessment […]
