Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The interplay between periodontics and restorative dentistry is present at many fronts, including location of restorative margins, alloy sensitivity, crown contours, and response of the gingival tissues to restorative preparations.
Periodontal tissues form the foundation for proper esthetics, function, and comfort of the dentition, as well as the periodontal health at the restorative gingival interface consider as prerequisite for successful outcome.
Success of fixed prosthodontics restorations is largely dependent upon the long term health and stability of the surrounding periodontal structures.
The purpose of the present study was to evaluate the clinical efficacy of 4 new gingival retraction systems; traxodent, Gingitrac, Nocord, and cord , on the basis of the time taken for placement, hemorrhage control ,the amount of horizontal gingival displacement and periodontal parameter (PI, GI, CAL and PD).

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
And from fixed prothodontic point of view there are several factors affect the success and durability of restorations. In general, the type of impression making, setting accuracy, material flow, temperature, humidity, mixing, disinfection and pouring time have effects on the final accuracy of the indirect restorations. Supra-gingival margins are effective in periodontal health maintenance, but do not provide optimal aesthetics.
The primary factor in defective record of marginal details is due to the inefficacy of the gingival displacement technique.
Traditionally, procedures for soft-tissue management and isolation are classified into three main approaches: Mechanical, chemical or surgical.
material and method:-
40 subjects were selected requiring fixed prosthesis according to inclusion and exclusion criteria.
The 4 gingival retraction systems were used on the prepared abutments randomly. The time taken for placement of each retraction system was recorded.
Hemorrhage score will be recoreded. The horizontal retraction was measured on polyether impressions made before the retraction and after retraction using stereoscope.
The periodontal parameter (PI, GI, CAL and PD) will be recorded pre-operative, 1 day post-operative and 7 days post-operative.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Gingitrac
The gingitrac cartridge was attached to the automixing gun and then the mixing syringe with intraoral tip was placed into the gingival sulcus and gingival retraction material was applied all around the selected abutment. After injecting the retraction material ,the corresponding comprecap was placed on to the abutment to push the material deep into the gingival sulcus. After 4 min, the comprecap with the set retraction material attached to it was removed from the patient mouth.
No Cord impression material
the no cord self- retracting impression material placed directly in the tray
cord
Cords were placed in the gingival sulcus with use of a cord packer, and left in situ for 10 min before making the impression. None of the retraction cords were immersed in any solution or medicaments prior to insertion.
