Where are the sextants in the maxillary anterior?
Gingival crevices around each tooth were examined, and researchers recorded the deepest probing depth found in each sextant. The probing depths in the maxillary anterior and mandibular anterior regions ( sextants two and five) were shown to have significant relationships with OHIP-14 subscales.
Why was the sextant used in the Davis quadrant?
Like the Davis quadrant, the sextant allows celestial objects to be measured relative to the horizon, rather than relative to the instrument. This allows excellent precision. Also, unlike the backstaff, the sextant allows direct observations of stars. This permits the use of the sextant at night when a backstaff is difficult to use.
