Periodontics instruments.

  1. 1. PeriodonticsInstrumentsExplorers- Use:1.Locate Sub-gingival Deposits and Caries.2.Check Smoothness of root surface after planning.3.Assess Restorative problems.- Thin, Flexible, Wire-like working end. Taper to sharp point.- Curved, Right-angled & Area specific.Periodontal Probes- Use:1.Locate &Measure depth of pocket and determine it’sconfiguration.2. Assess Loss of Attachment.3. Detect Sub-gingival Deposits.- Tapered with blunt round tip, mm markings for accuracy.- Ball-end to avoid penetration into junctional epithelium.- Diameter less than or equal 0.6 mm.- Probing Force more than 0.25 N traumatize healthy tissue. (25-50g forclinic)- Ball-end to avoid penetration into junctional epithelium.A, Marquis color-coded probe. B, UNC-15 probe. C, University of Michigan “O”probe, with Williams markings. D, Michigan “O” probe with markings at 3, 6, and8 mm. E, World Health Organization (WHO) probe.
  2. 2. WHO Probe or Screening Probe- 0.5 mm ball at tip- mm markings at 3.5, 8.5, 11.5 mm- Color coding from 3.5 to 5.5 mmWilliams Probe- Marking at 1, 2, 3, 5, 7, 8, 9, 10 mm- Color & non-Color codingMarquis Color-coded Probe:- Calibrations in 3 mm sectionsUNC-15 Probe- 15 mm long- Marking at each mm- Color coding at 5, 10, 15 mmMichigan “O” Probe- With Williams markings, or- With markings at 3, 6, 8 mmNabers Probe- Used for Furcation- Accurate Horizontal detection- 1 N for Mesial & Distal- 2 N for Facial & Lingual – Color coding 3, 6, 9, 12 mmGoldman Fox- Flat end- with Williams marking at 1, 2, 3, 5, 7, 8, 9, 10 mmMaryland Moffit- with Williams marking at 1, 2, 3, 5, 7, 8, 9, 10 mm- Ball endA, Curette; B,sickle; C, file; D, chisel; E, hoe.
  3. 3. Sickle Scalers- Use: 1. Coronal & Supra-gingival Scaling only, due to large blade.2. Removal of Supra-gingival Deposits especially below contactsin Anterior region.- Method:Pull Stroke.- Thin, Triangular cross section, Point to Tip, Double cutting edge andWorking tip.- Pointed Tip increases root surface roughness.- Straight for Anterior & Curved for Posterior.- Single-end or Double-end.- Other types: Cumine Universal Scaler& Posterior JacquetteScaler.Hoe Scalers- Use: 1. Remove Ledges or Heavy Rings of Calculus Supra & Sub-gingival.2. Planning & Smoothening Root surface.3. Remove Calculus remnants.4. Remove Heavy deposits on Distal of Terminal Molar.- Method:Pull Stroke.- Cutting edge beveled at 45 degrees.- Blade bent at 99 degrees, back of blade is rounded.- 2 contact point with tooth.Files- Use: 1. Fracture or Crush Large Deposits in Deep, Narrow PeriodontalPockets.2. Effective for Burnished or Smooth Calculus, TenaciousCalculus. (Remove Tenacious Sub-gingival Deposits).3. Remove Overhanging Restorations.- Method:Pull & Push and Pull Strokes.- Doesn’t reach apical portion of pocket.- Not indicated to remove Bacterial Plaque or Endotoxins.- Head (Body), Shank & Handle.- Hirschfield series: 3 cutting edges – Fracture Heavy Calculus- Orban design: 6 cutting edges – Fracture Heavy Calculus- Bendbug File: 10-11 cutting edges – Smoothen Roots and CEJ, &Remove Moderate Deposits.- Less no.of cutting edges more the fracture of large deposits.
  4. 4. Chisel Scalers- Use: 1. Proximal of Anterior Teeth.2. Remove Tenacious Sub-gingival Deposits.- Method:Push Stroke. Horizontally from Labial to Lingual.- Double-ended.- Curved & Straight Shanks on ends with 45 degrees bevel.Curettes- Use: 1. Remove Deep Sub-gingival Calculus2. Root Planning altered Cementum.3. Remove Soft Tissue lining of Periodontal Pocket.4. Used on Flat concave and convex root surfaces.- Method:Push Stroke. Horizontally from Labial to Lingual.- Single-ended or Double-ended.- Semi-circular cross section; convex base.- Rounded Tip.- 1 or 2 Cutting edges.- No sharp points other than cutting edge of blade.Universal Curettes- Use:Remove Plaque & Calculus at Interproximal surface, betweengingival or crown margin & Inaccessible Furcation.- Used in Most Areas.- 90 degrees with lower shank. (when seen in cross section from tip)Face offset beveled at 80 to 90 degrees to Terminal shank.Gracey- Area Specific Curettes- Use:Sub-gingival Scaling & Root Planning.- Only instrument with Curved Cutting edge. Adapt to curved tooth surfaces.- Face offset beveled at 60 to 70 degrees.- Lower number more anterior in mouth.#1-2 and #3-4 : Anterior#5-6 : Anterior & Premolar#7-8 and #9-10 : Posterior Facial & Lingual#11-12 : Posterior Mesial#13-14 : Posterior DistalGracey after Five e.g: Hu-Friedy after Five- Extend shank 3 mm. Used for Pocket more than 5 mm.Gracey Mini e.g: Hu-Friedy Mini- Half Standard.
  5. 5. Periodontal Endoscope- Use:Visualize Deep pockets and Furcation during scaling and rootplanning.SchawartzPeriotreivers- Set of double-ended highly magnetized instruments designed for retrieval ofbroken instrument tips from periodontal pocket.Plastic Instrument- Avoid Permanent Damage to Implant surfaces.Diagnostic InstrumentsPeriodontal Probes, Nabers Probes, & Explorers.Scaling & Root Planning and Curettage InstrumentsSupra-gingival Scaling (Sickle scaler, Cumine Universal scaler, PosteriorJacquettescaler)Sub-gingival Scaling (Hoe, Chisel and File scalers& Curettes)Sonic & Ultrasonic InstrumentsCleansing & Polishing InstrumentsRubber Cups, Brushes, Air Power Abrasive System.Surgical InstrumentsExcisional & Incisional Instruments, Surgical Curettes and Sickles,Periosteal Elevators, Surgical Chisels, Hoes, Files, Scissors & Nippers.
