Quadrant dentistry

From WikiMD's Wellness Encyclopedia

Quadrant dentistry is a treatment approach sometimes used in individuals who need much dental treatment.[1]: 189, 190  Quadrant dentistry means that all the dental treatment required in a quadrant is carried out in a single appointment. This is perceived as convenient for some dentists and some patients, as fewer appointments are required overall.

The dentition is divided into quadrants:

  • Upper right quadrant: upper right first incisor to upper right wisdom tooth
  • Upper left quadrant: upper left first incisor to upper left wisdom tooth
  • Lower right quadrant: lower right first incisor to lower right wisdom tooth
  • Lower left quadrant: lower left first incisor to lower left wisdom tooth

Inferior alveolar nerve blocks anesthetize all the teeth in a lower quadrant, so it can be convenient as only one injection is required for quadrant dentistry carried out in the lower teeth. Rubber dam is often used in this technique.[2] If a tooth extraction is carried out in the same appointment as placing an amalgam filling, amalgam tattoo can result.
