  2. 2. Isolation Of Operating Field Presented by : Arpit Viradiya Guided by : Dr. Sandeep Metgud Dr. Deepali Agrawal
  3. 3. Contents  Introduction  History  Classification – Isolation from moisture – Direct methods - Indirect methods - Isolation from soft tissues Direct methods • Rubber dam • Cotton rolls & holder • Throat shield/Gauze piece • Absorbent wafers • Suction devices • Gingival retraction cord
  4. 4. Indirect methods • Comfortable position of the patient & relaxed surroundings • Local Anesthesia • Drugs  Isolation from Soft tissues • Retraction of cheeks, lips and tongue • Retraction of gingiva  Advancements  References  Conclusion
  5. 5. Introduction Isolation of operaring field is essential to the correct performances of most operative procedures. The term oral environment refers to the following items which require proper control to prevent them from interfering with the execution of any restorative procedures •Saliva •Moving organs, i.e. tongue •Lips & Cheek •The periodontium •The contacting teeth and restoration •The sulci, floor of the mouth and palate •Respiratory moisture
  6. 6. History •The rubber dam was first described over 120 years ago when in March 1864 Dr. Sanford Barnum first explained its use at meeting of Valley Dental Society in New York. •Rubber dam frames were described in early 20th century as Metal Fernauld’s design. More recent designs have taken advantages of developments in plastics to produce frames which are radiolucent.
  7. 7. Goals of isolation Acc.to Sturdevant 1. Moisture control  It refers to excluding sulcular fluid, saliva & gingival bleeding from the operating field. 2. Retraction & Access  retraction & access provides maximal exposure of the operating site
  8. 8. 3. Harm prevention • Small instruments and restorative debris can be aspirated or swallowed. •Soft tissue can be damaged accidentally. •With moisture control and retraction, a rubber dam, suction devices, absorbents, and occasional use of a mouth prop prevents harm to the patient and improves operator efficiency.
  9. 9. Local anesthesia Use of these agents reduces salivation apparently because the patient is more comfortable, less anxious and less sensitive to oral stimuli thus reducing salivary flow.
  10. 10. Rubber Dam Isolation  First introduced in 1864 by S.C.Barnum •Reasons for using a Rubber dam Safety Moisture control Patient management
  11. 11. Advantages of using a rubber dam 1. Dry, clean operating field 2. Access & Visibility 3. Improved properties of dental materials 4. Protection to patient and operator 5. Increased operator efficiency
  12. 12. Disadvantages • Asthmatics and mouth breathers • Partially erupted and severely malpositioned teeth. • Some 3rd Molars. • Patients who are allergic to latex • Psychological reasons • Minor damage to marginal gingiva &cervical cementum during clamp removal. • Metal crown margins show microscopic defects following clamp removal. • Ceramic crowns could fracture if clamps are allowed to grip the margins. • Time consumption and patient objection.
  13. 13. Armamentarium 1. Rubber dam sheets 2. Rubber dam clamps 3. Rubber dam retainer forceps 4. Rubber dam holder 5. Rubber dam punch 6. Rubber dam template/stamp 7. Dental floss 8. Wedget 9. Lubricant 10. Modeling compound 11. Anchorage other than retainers
  14. 14. Rubber dam sheets • Rubber dam is made from natural latex rubber • manufactured as continuous rolls in two widths (5*5 inch or 6*6inch) • Traditional rubber dam is black in color but it is now made in at least four alternative color green, blue, grey and natural (natural color is translucent). Thickness Manufactured in range of five thicknesses: Grade Thickness mm (inches) Thin 0.15 (0.006) Medium 0.20 (0.008) Heavy 0.25 (0.010) Extra heavy 0.30 (0.012) Specia heavy 0.35 (0.014)
  15. 15. Rubber dam frame (Holder) The rubber dam frame maintains the borders of the dam in position. The young holder is a U shaped metal frame with small metal projections for securing the borders of rubber dam.

  17. 17. PLASTIC FRAMES NYGARD-OSTBY FRAME SAUVEUR OVAL FRAME
  18. 18. Rubber dam clamps (Retainer) • Consists of 4 prongs and 2 jaws connected by a bow • Used to anchor the dam to the most posterior teeth to be isolated • Also retract gingival tissues • Winged & wingless retainers are available.
  19. 19. •When positioned on a tooth, a properly selected retainer should contact the tooth in four areas-two on the facial surface and two on the lingual surface. •Retainer should not move on the anchor tooth or it will injure the gingiva and tooth, resulting in postoperative soreness or sensitivity.
  20. 20. Rubber dam punch • A precision instrument having a metal table and a tapered, sharp pointed plunger which is used to produce clean-cut holes in the rubber dam sheet through which the teeth can be isolated. • 1. single hole punch • 2. multi-hole punch a.

  27. 27. Rubber dam stamp & template
  28. 28. Accessories Dental floss • Required for testing the Interdental contacts and for making ligatures when they are needed. • Also aid in flossing the rubber dam through tight contacts
  29. 29. Napkin : • The rubber dam napkin is a precut sheet of absorbent material which can be placed between the rubber sheet and the oral soft tissues.
  30. 30. Lubricant: A water-soluble lubricant applied to both sides of the dam in the area of the punched holes facilitates the passing of the dam through the proximal contacts.
  31. 31. Modeling compound • Low fusing modeling compound is used sometimes used to secure the retainer to the tooth to prevent retainer movement during the operator procedure. • Wedget This is an elastic cord generally used to secure the dam around the teeth farthest from the clamp. It can also be used to push the dam through the interproximal contact and also in some places as a retainer instead of clamp.
