CONSTANT PRESSURE PERIODONTAL PROBE

摘要

A constant pressure periodontal probe (1) has a probing portion (3) and connecte d to a handle (2) through a flexing joint (10). A backing portion (15) extends from the handle adjacent to but spaced away from the probe tip (6) such that a gap (17) exists between the probe portion (3) and the backing portion (15). As the probin g portion (3) is inserted into a pocket between the tooth and gum, the amount of resistance causes the probe portion (3) to be displ aced about the flexible joint (10), closing the gap between the probing (3) and backing (15) portions. When the probing portion (3) contacts the backing portion (15), a constant insertion pressure has been reached and a reading is taken to determine the dept h of the pocket.Utilizing such a constant pressure periodontal probe (1) assures that each reading is taken at a set pressure, prev enting damaging to the gum tissue and assuring accurate readings.
