A constant pressure periodontal probe (1) has a probing portion (3) and connected 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 probing portion (3) is inserted into a pocket between the tooth and gum, the amount of resistance causes the probe portion (3) to be displaced 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 depth of the pocket.Utilizing such a constant pressure periodontal probe (1) assures that each reading is taken at a set pressure, preventing damaging to the gum tissue and assuring accurate readings.

Sonde parodontale à pression constante (1) composée d'un élément d'exploration (3) et reliée à un manche (2) par une charnière flexible (10). Un élément de soutènement (15) s'étend du manche adjacent à l'extrémité de la sonde (6) mais non contigu à celle-ci, de façon qu'il existe un espace (17) entre l'élément d'exploration (3) et l'élément de soutènement (15). Lorsque l'élément d'exploration (3) est introduit dans une poche entre la dent et la gencive (10), le degré de résistance fait en sorte que l'élément d'exploration (3) se déplace autour de la charnière flexible (10), comblant ainsi l'espace entre l'élément d'exploration (3) et l'élément de soutènement (15). Lorsque l'élément d'exploration (3) est mis en contact avec l'élément de soutènement (15), une pression constante à l'insertion est obtenue et une lecture est faite afin de déterminer la profondeur de la poche. L'utilisation d'une telle sonde parodontale à pression constante (1) permet de s'assurer que la lecture est faite à une pression fixe; on évite ainsi de blesser la gencive et les lectures sont précises.
