简要总结
This study aims to compare the horizontal gingival displacement by using a retraction cord and aluminum chloride gel, and also to determine the time taken for placement and hemorrhage after the procedure by using a retraction cord and aluminum chloride gel. Patients of both genders, age ranges from 18 to 50 years, will be selecting requiring fixed prosthesis with of minimum two abutments. This study divided in two parallel groups of 33 patients in each group.
详细描述
To compare the effectiveness of a knitted retraction cord and 25% aluminum chloride-containing gel for horizontal gingival displacement, time taken for placement, patient discomfort and bleeding control after retraction cord removal and gel application with improved quality and better marginal fit of fixed prosthesis. This study include patients from range 18 to 50 years, Finishing line margins will be equigingival,Clinically and by radiographic analysis, healthy gingiva and periodontium around the abutments. Bleeding on probing index score-0 included,plaque index score(1-3) not included.
exclusion criteria is Sub-gingival or supra-gingival margins Patient having inappropriate root canal treated tooth. i.e Periapical pathosis over obturation, short root canal,Patient with probing depth 3mmm and above with uncontrolled bleeding. Patient with uncontrolled diabetes, hypertension or neurological disease.
SAMPLE TECHNIQUE: Non- probability consecutive sampling technique. Two groups will be formed among 66 patients with control group is retraction cord group and make two impressions after crown preparation with a finishing line Equiogingival margins will form than in group A in this study apply knitted retraction cord ultra Pak in thickness of .oo mm through retraction cord instrument by cord pecker retraction gel by company provided disposable tips with syringe into the circumferential area of sulcular preparation for 2 minutes and group B using gingival retraction gel containing 25% aluminum chloride viscous tat by ultra-dent after application of gingival retraction gel into sulcular area for 1-3minutes and wash with firm air water spray and will make impressions by one-step technique putty with the light body in metal stock trays then remove and check the impression for any inaccuracy then disinfect the impressions and pores with type 2 hard plaster and mention the code over cast that will not mix. The time required for placement of both gingival retraction systems will be recorded by using stopwatch in seconds and haemorrhage control will be checked by clinically observed with the naked eyes after air water spray up to 3 -5 seconds comparison of horizontal displacement on cast will be analyzed by stereomicroscope images using image analysis software at Dow dental lab.
