Definitions

  • the present invention generally relates to a field of medicine. More particularly it relates to a method and a device to measure the width of attached gingiva in human jaws.
  • Oral mucosa consists of three zones namely the gingiva and hard palate, termed as the masticatory mucosa; the dorsum of the tongue (specialized mucosa) and the oral mucous membrane (lining mucosa).
  • Gingiva is that part of oral mucosa that surrounds the neck of teeth in collar like fashion.
  • Gingiva is comprised of unattached gingiva, attached gingiva, and interdental gingiva.
  • the unattached gingiva is free and not attached to the underlying periosteum.
  • the attached gingiva is that part of gingiva which is attached to the underlying periosteum and it’s an important dimension for periodontal health. So, it is of utmost importance to maintain the width of attached gingiva.
  • the width of attached gingiva varies from tooth to tooth and also among the individuals with the need to maintain "adequate” or “sufficient” dimension of the gingiva.
  • the need for an adequate amount of keratinized tissue or attached gingiva for maintenance of periodontal health is desired and the mucogingival junction serves as an important clinical landmark in periodontal evaluation.
  • There are various methods of locating the mucogingival junction namely the functional method and the visual method, which aids in the measurement of the width of attached gingiva.
  • the simple roll test or functional method for determining the mucogingival junction is done by assessing a borderline between the movable and immovable tissue wherein, tissue mobility is determined by running a periodontal probe positioned horizontally from the vestibule toward the gingival margin with light pressure. [1] And at a point where the probe stops rolling upwards it is regarded as MGJ.
  • the dimension which is to be recorded is the depth of the pocket or sulcus and it is regarded as the first dimension. Once the position of mucogingival junction (MGJ) is detected, the length from MGJ to gingival margin is recorded externally as is regarded as the second dimension.
  • MGJ mucogingival junction
  • the problem is that we have to take the recordings for both the dimensions at separate times, i.e. one after another by periodontal probe.
  • the solution to this problem is the present invention which can simultaneously take both the readings and save the time.
  • the present invention has come out with the method and the design of bifurcated periodontal probe, which can simultaneously record depth of periodontal pocket (First Dimension) and the length of keratinized tissue (Second Dimension) and further the important dimension width of attached gingiva by subtracting the two mentioned dimensions at a point of time.
  • One arm of the bifurcated periodontal probe seats inside into the periodontal pocket and the other arm remains externally and can be adjusted to coincide with the mucogingival junction.
  • Indian patent application number 202147016668 with priority number U.S. A.62/729460 characterized by a system for detecting tissue inflammation, and gingivitis specifically, including a light emitter configured to emit light at a tissue region within a user's mouth; a light detector configured to detect optical signals diffusely reflected through the tissue region over a period of time, wherein the present invention is characterized for calcula tion of width of attached gingiva.
  • W02005011518A1 the invention disclosed a dental instrument and the use of this dental instrument to measure deposits and other imperfections on a tooth surface.
  • EP0435912B1 is characterized by an invention for means of improving oral hygiene which includes a dentifrice for the differential disclosure of "new" and “old” plaque, a toothbrushing apparatus which has a head provided with an arras'- of upstanding bristles formed into a V-shaped and a probe adapted for use in assessing the degree of inflammation of various animal tissues.
  • JPH101317268A describes a gingival evaluation method to evaluate the surface layer state of gingivae with high accuracy in a short time by measuring the dielectric constant of the gum, obtaining the moisture density of the gum from the dielectric mitigation of the water of the gum and evaluating the surface layer state of the gingiva based on the obtained moisture density.
  • the principle objective of this disclosure is to provide a periodontal probe which measures the width of attached gingiva as, it is an important dimension for evaluation of periodontal health.
  • Another objective is to provide a simple and easy method which saves time as the bifurcated periodontal probe has first probe that measures the depth of pocket while it is seated, simultaneously, the second probe externally measures the length of keratinized tissue. The readings of both the probes are subtracted to determine the width of attached gingiva.
  • Another objective is to provide the rotating screw which can be manually adjusted to coincide with the mucogingival junction.
  • the embodiment rotating screw facilitates the worm gear mechanism for moving the second probe up and down.
  • the present invention pertains to a bifurcated periodontal probe for calculating the width of attached gingiva which has a handle made up of stainless steel and is hollow from inside.
  • the handle is 10 cm long with a diameter of 7- 8 mm.
  • the handle extends to another embodiment neck which narrows down in width from 7- 8 mm at the proximal end to 5 mm at the distal end.
  • the embodiment’s handle extends into the neck which constricts and converges down making an outer angle of 120-130 degrees with the shaft.
  • the neck terminates into a shaft which bifurcates into distal arm and proximal arm.
  • the distal arm extends into an embodiment first probe and the proximal arm extends into the second probe.
  • the first probe is a fixed probe which measures the depth of periodontal pocket and rests into the periodontal pocket.
  • the first probe is 15 mm long with marking from 1- 10 mm staring from the lower distal end.
  • the diameter of probe is 1mm.
  • the rotating screw is in the midway of handle which is facilitated by the working mechanism of worm gear for the present invention.
  • the embodiment axle extends from the centre of the rotating screw, the axle extends through the distal end of the rotating screw and is suspended with the first wheel in the centre of axle.
  • This assembly of wheel- axle joint propagates the worm gear mechanism.
  • the rotating screw has an axle in the centre which is connected to the first wheel of the worm gear, this wheel and axle joint gets rotated inside the hollow handle, when, the rotating screw is rotated externally from the outer surface of the handle.
  • the wheel and axle in turn rotates the next wheel which is suspended at an angle of 90 degrees, this facilitates the rotation of chain of wheels working on worm gear mechanism.
  • the distal most wheel of the chain propagates the movement of the second probe as the serrations of the distal wheel interlock with the serrations on the upper end of the second probe (towards the neck) which moves the second probe up and down.
  • the horizontal distance between two probes is 2mm.
  • the second probe that extends from the proximal arm of the bifurcated probe is 20 mm long and has markings from 1-10 mm starting at the lower distal end. It has diameter of 1.5- 2mm. It is the movable probe which works on the worm gear mechanism and the second probe has the provision of moving across an open gap on the shaft which facilitates its movement up and down for adjusting the lower end of the probe to coincide with the MGJ.
  • Embodiments explained herein relate to the bifurcated probe for calculating the width of attached gingiva.
  • the rotating screw (102) is in the midway of handle which is facilitated by the working mechanism of worm gear for the present invention.
  • the embodiment axle (109), extends from the centre of the rotating screw (102), and the distal end of the axle (109), is suspended with the first wheel. This assembly of wheel- axle joint propagates the worm gear mechanism.
  • the second probe (104) that extends from the proximal arm of the bifurcated probe with the markings from 1-10 mm starting at the lower end. It is the movable probe with two ends the lower end and the upper end. The lower end is made to coincide with the mucogingival junction (MGJ), while, the upper end of the second probe can move across an open gap on the shaft (111) which facilitates its movement up for adjusting the lower end of the probe to coincide with the MGJ.
  • the present disclosure is user friendly and saves time. It provides the design of the bifurcated periodontal probe for calculating the width of attached gingiva by simultaneously making two measurements; i.e. the depth of periodontal pocket from first probe (103) and length of keratinized gingiva from the second probe (104).
