periodontal instruments and their uses periodontal instruments and their uses Presentation Transcript

  • PERIODONTAL INSTRUMENTS & there uses Wtar omer Zara khasrow Azmar akram
  • PERIDONTAL INSTRUMENTS  PERIODONTAL PROBES  EXPLORERS  SCALING, ROOT-PLANING & CURETTAGE  PERIODONTAL ENDOSCOPE  CLEANSING & POLISHING INSTRUMENTS
  • CLASSIFICATION • PERIODONTAL PROBES- • EXPLORERS-
  • SCALING, ROOT-PLANING AND CURETTAGE INSTRUMENTS A. Curette : for sub gingival scaling, root planning and removal of the soft tissue lining the pocket B. Sickle Scaler : to remove supra gingival calculus C. File D. Chisel E. Hoe to remove tenacious calculus and altered cementum
  • Ultrasonic and sonic instruments- for cleansing and polishing tooth surface and curetting the soft tissue wall of the periodontal pocket CLEANSING & POLISHING INSTRUMENTS eg : rubber cups, brushes, dental tape, air-powder abrasive system
  • PARTS OF INSTRUMENT
  • • It is usually long, thin, and blunted at the end. The primary purpose of a periodontal probe is to measure pocket depths around a tooth in order to establish the state of health of the periodontium . There are markings inscribed onto the head of the instrument for accuracy and readability. PERIDONATAL PROBES
  • SICKLE SCALERS
  • SICKLE SCALERS / SUPRAGINGIVAL SCALERS • USED TO REMOVE LARGE CALCULUS DEPOSITS FROM THE ENAMEL SURFACE • USED WITH A PULL STROKE.
  • HOE SCALERS  HOE SCALERS ARE USED FOR SCALING OF LEDGES OR RINGS CALCULUS
  • CHISEL SCALERS • IT IS DESIGNED FOR THE PROXIMAL SURFACE OF TEETH TOO CLOSELY SPACED TO PERMIT THE USE OF OTHER SCALERS • IT IS USUALLY USED IN ANTERIOR PART OF THE MOUTH
  • FILES • THEIR PRIMARY FUNCTION IS TO FRACTURE OR CRUSH LARGE DEPOSITE OF TENACIOUS CALCULUS • FILES CAN EASILY ROUGHEN ROOT SURFACES WHEN USED IMPROPERLY THEREFORE, THEY ARE SUITABLE FOR FINE SCALING
  • CURETTES CURETTES ARE OF TWO TYPES 1. UNIVERSAL 2. AREA SPECIFIC UNIVERSAL CURETTES -USED IN ANY AREA -BOTH CUTTING EDGES USED -CURVED IN ONE PLANE -FACE OF BLADE AT 90 DEGREE TO SHANK AREA SPECIFIC -USED IN SPECIFIC AREAS -ONE CUTTING EDGE USED -CURVED IN TWO PLANE OFFSET BLADE
  • • SCHWARTZ PERIOTRIEVERS A SET OF DOUBLE ENDED HIGHLY MAGNETISED INSTRUMENTS DESIGNED FOR THE RETRIEVEL OF BROCKEN INSTRUMENT TIPS • PLASTIC INSTRUMENTS FOR IMPLANTS TO AVOID SCARRING AND PERMANENT DAMAGE TO IMPLANTS
  • DIAMOND COATED FILES UNIQUE INSTRUMENTS USED FOR FINAL FINISHING OF ROOT SURFACES
  • QUETIN FURCATION CURETTES HOES WITH A SHALLOW, HALF MOON RADIOUS THAT FITS INTO ROOF OR FLOOR OF FURCATION & DEVELOPMENTAL DEPRESSIONS OF ROOT SURFACE
  • SONIC AND ULTRASONIC ULTRASONIC INSTRUMENTS :USED FOR REMOVING PLAQUE, STAINS, FOR SCALING & CURETTAGE SONIC INSTRUMENTS : LESS POWER FOR CALCULUS REMOVAL THAN ULTRASONIC UNITS
  • MAGNETOSTRICTIVE ULTRASONIC UNIT
  • PERIDONTAL ENDOSCOPY Use of a small fiber optic endoscope attached to a specially designed dental instrument, such as an explorer, showing sub gingival deposits in a magnified view.
  • CLEANSING & POLISHINING • RUBBER CUPS:- CONSIST OF A RUBBER WITH OR WITHOUT WEBBED CONFIGURATIONS IN THE HOLLOW INTERIOR • USED IN HANDPIECE WITH A SPECIAL PROPHYLAXIS • A GOOD CLEANSING & POLISHING PASTE THAT CONTAIN FLOURIED SHOULD BE USED & KEPT MOIST TO MINIMIZE FRICTION HEAT
  • BRISTLE • AVAILABLE IN WHEEL & CUP SHAPES • USED IN PROPHYLAXIS ANGLE WITH A POLISHING PASTE DENTAL TAPE DENTAL TAPE WITH POLISHING PASTE IN USED FOR POLISHING PROXIMAL SURFACE THAT ARE INACCESSIBLE TO OTHER POLISHING INSTRUMENTS
  • AIR POWDER POLISHING Air-powder polishing is used with a specially designed handpiece. This device is called Prophy- jet. It delivers an air- powder slurry of warm water and sodium bicarbonate for polishing. It is very effective for the removal of extrinsic stains and soft deposits
  • PERIDONTAL KNIVES • USED FOR GINGIVECTOMY
  • SURGICAL BLADES • USED IN PERIDONTAL SURGERY
  • PERIOSTEAL ELEVATOR • NEEDED TO REFLECT & MOVE THE FLAP AFTER THE INCISION HAS BEN MADE FOR FLAP SURGERY
  • TISSUE FORCEPS • USED TO HOLD THE FLAP DURING SUTURING • USED TO POSITION & DISPLACE THE FLAP AFTER THE FLAP HAS BENN REFLECTED
  • SCISSORS AND NIPERS • USED TO REMOVE TABS OF TISSUE DURING GINGIVECTOMY, TRIM THE MARGIN OF FLAP, ENLARGE INCISION IN PERIDONTAL ABSCESES ,REMOVE MUSCCHMENT IN SURGERY GOLDMAN – FOX SCISSORS
  • NEEDLE HOLDER • USED TO SUTURE THE FLAP AT THE DESIRE PORTION AFTER SURIGAL PROCEDURE HAS BEEN COMPLETE. CASTROVEJO NEDDLE HOLDER
  • THANK YOU
