In fixed restoration, gingival displacement plays an important role in excellent reproduction of marginal details. Gingival retraction involves deflection of gingival tissues away from the tooth to expose the cervical part or margins of prepared tooth. A sulcular width of 0.15 to 0.20 mm is needed for accurate impression. If the sulcus width is less than this value, impression material is subjected to rupture and deformation, with reduced marginal accuracy. An inappropriate gingival displacement technique can be a primary factor in defective recording of marginal details. Various methods for gingival retraction are mechanical, mechanochemical, electrosurgery, rotary gingival curettage, laser etc. Following are few acceptable criteria during gingival displacement:(1) Minimum of 0.22 mm space laterally and vertically should be present between finish line and gingiva for impression material to record without distortion. (2) for accurate trimming of recovered die additionally small amount of impression material should flow beyond prepared margins, (3) especially when elastomeric impression material, gingival fluid seepage and hemorrhage should be considered (4) protection from irreversible hard and soft tissue damages, (5) protection against dangerous systemic effects. Mechanical method of gingival retraction uses both impregnated and non-impregnated retraction cords. Common disadvantages including damage to junctional epithelium, post-retraction inflammation and gingival recession, bleeding and patient discomfort during procedure and technique sensitive. Various other techniques have been introduced to overcome all these disadvantages thereby replacing the use of retraction cord which includes retraction paste, gels, foams, lasers and surgery. While researches still conclude use of retraction cord as gold standard due to its cost-effectiveness and reliability and excellent displaceability of gingiva.Polytetrafluoroethylene (PTFE) tape, a synthetic fluoropolymer. Commercially referred as Plumber’s tape or Teflon is heat stable, nonadherent with low co-efficiency of friction inert and non-reactive to oral fluids as well as other acids used in dentistry. widely used in the field of clinical dentistry for isolation and in guided bone regeneration. Use of PTFE tape for gingival retraction is limited. Recent study has shown that conventional gingival retraction cord and PTFE cord incorporated with aluminium chloride displayed similar outcomes of ease of placement and bleeding after cord removal. This study will be focusing on a new technique to standardize the use of PTFE tape for gingival retraction in comparison with conventional retraction cord on an unprepared tooth.
