Flashcards

Radiographic Caries Detection

Identifying tooth decay using X-rays, focusing on areas of radiolucency, specifically desmineralization of at least 30-40%.

Radiographic Periodontal Disease

Diagnostic radiography used to spot periodontal diseases, focusing on the periapical tissues and interproximal areas.

Radiolucent Areas

Areas appearing dark/radiolucent on X-rays, often indicating decay, but may also be restorations or other issues.

ICDAS Caries Classification

A system (0-6) for classifying the severity of dental caries based on clinical and radiographic observations (extent of decay and enamel/dentin/pulp involvement.)

Study Notes

Diagnóstico Radiográfico de Caries Dental

  • Áreas radiolucentes: These areas show up as lighter on X-rays, indicating possible dental caries.
  • Tejidos periapicales: X-rays can reveal areas around the tooth roots; changes here can also signal problems.
  • Áreas interproximales: X-rays can detect caries between teeth.
  • Proceso de caries: Caries progresses through demineralization, followed by potential remineralization.
  • Lesiones de caries: Detection of caries depends on the degree of desmineralization and remineralization; it might not show up clinically or radiographically in early stages.
  • Superficie proximales: Caries in the surfaces between teeth commonly become noticeable when 30-40% of the tooth surface has demineralized.

Diagnóstico Radiográfico de Enfermedad Periodontal

  • Áreas radiolucentes: These areas can show up in an X-ray, which suggests possible pathology.
  • Restauraciones: X-rays can reveal fillings, which can have different shapes and degrees of extensions.
  • Cambios dentarios: Teeth can be affected by past restoration, revealing radio translucent areas.
  • Áreas radiolucentes cervicales: X-ray images can sometimes show radiolucent areas associated with the tooth root's neck. This could have multiple causes, not just pathological ones.
  • Áreas Radiolucentes debajo de Restauraciones: There can be radiolucent areas below existing restorations that could indicate ongoing problems. The analysis should focus on the edges of fillings, including convex or concave shapes and adjacent caries.
  • Diagnóstico de caries en radiografías: Accurate diagnosis depends on proper x-ray angle and technique. Incorrect technique could lead to misdiagnosis.

Otros Aspectos Radiográficos de Áreas Radiolucentes

  • Caries residuales: These are remains of demineralized tooth tissues.
  • Restauraciones adhesivas: X-rays can detect fillings, their extensions and types .
  • Cambios dentarios: Radiographs reveal changes related to dental restorations.
  • Cervical burn-out: A radiolucent area at the cervical region of a tooth that usually shows symmetrical pattern.
  • Áreas Radiolucentes: This includes various factors such as caries, restorations and more. This area of focus is crucial when evaluating an X-ray.

Diagnóstico Radiográfico de Tejidos Periapicales

  • Tejidos periapicales: X-rays help evaluate areas surrounding tooth roots for any problems (e.g., infection, inflammation).
  • Rizogénesis: X-rays document developmental stages or teeth, distinguishing between crown and root formation.
  • Corona: X-rays depict the visible portion of the tooth, including any restorations and morphology.
  • Raíz: X-rays reveal root shape, canals, and any abnormalities.
  • Hueso: X-rays evaluate the density and structure of bone surrounding the tooth roots.
  • Cresta alveolar: X-ray images of this area reveal its form and condition near the ligament and cement.
