6 topics with concise breakdowns: definitions, key facts, and class questions.
Semiotics is the alphabet of a dentist's clinical thinking. In this chapter, we analyze how the tissues and organs of the maxillofacial region "signal" the development of pathology. Without a clear understanding of basic symptoms and syndromes, making a correct diagnosis in clinical departments will be impossible.
This section covers the manifestations of diseases across all key structures. We will consistently analyze the signs of lesions affecting hard dental tissues, pulp, and periodontium, as well as periodontal diseases. Special attention is paid to the semiotics of pathologies of the oral mucosa, jaw bones, and temporomandibular joint (TMJ).
During practical classes and colloquia, the differential diagnosis of pain syndromes (for example, how to distinguish pulpitis from periodontitis by the nature of the pain), as well as primary and secondary mucosal lesions, are most frequently asked about. Learn to connect the patient's subjective complaints with objective clinical signs — this is the foundation of your future practice.
What is the difference between a pathognomonic and an obligate symptom?
A pathognomonic symptom occurs in only one specific disease (it is unique). An obligate symptom is a leading sign that is necessarily present in a given disease, but it may also occur in other pathologies.
How to properly check Schmreker's sign?
The clinician should gently palpate the mucosa overlying the apex of the causative tooth while simultaneously performing light percussion on its crown. A sensation of jarring felt under the finger indicates the presence of a granuloma or cyst.
What radiological signs of periodontitis are observed in Cushing's syndrome?
Osteoporosis of the alveolar processes, thinning of the compact lamina, widening of the periodontal ligament space, and uniform atrophy of the interdental septa are detected.
How does Hunter's glossitis in pernicious anemia differ from changes in essential hypochromic anemia?
The local picture on the tongue in these conditions is similar. The main difference is that in hypochromic anemia, painful, stubbornly treatment-resistant fissures simultaneously form at the corners of the mouth.
In which disease does tooth loss occur painlessly and begin with the molars?
This symptom is a hallmark of Hand-Schüller-Christian disease (a type of histiocytosis).
What is Costen's syndrome?
This is temporomandibular joint (TMJ) pain dysfunction. Another name for this pathology is craniomandibular dysfunction.
