Abstract

Aim: To evaluate and compare four factors in gingival retraction using three different gingival retraction method (Retraction Cord, Magic foam retraction Cord and Laser gingival troughing). Vertical and horizontal gingival displacement, hemorrhage control and time taken for performing each method were evaluated.

Materials and Method: 30 patients requiring fixed partial denture with two abutments were selected for the study. Following tooth preparation, three gingival retraction systems were used on the prepared abutments randomly, such that each combination was repeated ten times with overall n value being 60. Williams probe was used to measure sulcus depth before and after retraction. The horizontal sulcular width was measured indirectly by making impressions and measuring them under stereomicroscope. Hemorrhage scores were recorded immediately after removal of the retraction system. The time taken for each method was recorded in seconds. All results were recorded, tabulated statistically, analysed and interpreted.

Conclusion: From the results of the present study, following conclusions were drawn;1) The depth and width or lateral displacement were more with retraction cord than with the other two method. 2) Hemorrhage control was best with magic foam, followed by laser with cord retraction having more haemorrhage. 3) Least time taken for gingival retraction was with Laser method, followed by magic foam, while retraction cord method consumed maximum time.
