Comparison of 3 different gingival retraction agents

Phase 3

Completed

Conditions: Disease of hard tissues of teeth,unspecified,

Registration Number: CTRI/2023/09/057754

Lead Sponsor: Dr Unnati Agarwal

Brief Summary: The above study *"* A Comparative Evaluation of Different GingivalRetraction Methods â€“ A Double Blinded In Vivo Study *"* is going to compare three different methods ofgingival retraction using three different gingival retraction materials andtheir potential in gingival retraction when used in single unit fixed partialdenture cases. It is going to be held over a period of 3 months. The study willbe carried out on patients requiring two separate single unit fixed partialdentures attending the Out Patient Department of Prosthodontics and Crown &Bridge in Sardar Patel Post Graduate Institute of Dental andMedical Sciences. A written informed consent will be obtained from each patientafter explaining the nature and outcome of procedure and the possibleconsequences and complications.

Gingival retraction reversiblydisplaces the gingival tissues so that bulk of low viscosity impressionmaterial can be introduced in the widened sulcus and the margins can be captured.Gingival tissues are displaced both laterally and vertically. Lateralretraction displaces the tissues and provides adequate bulk of impressionmaterial so that it can be removed from the mouth intact with no tearing.Vertical retraction exposes the undercut portion of the tooth apical to thefinish line.

Thepresent study is therefore undertaken to identify the most efficient gingivalretraction method out of Retraction Cord with Epinephrine, Retraction paste (3M)and Retraction Gel (Smart Retract) by measuring sulcus width and depth.

Acontrol group of plain Retraction cord will be used in one single unit FPD andthe retraction method to be compared will be used in another single unit FPD inthe same patient, and the two groups will be compared.
