简要总结
This in vivo study will be conducted in Department of Prosthodontics, Uttaranchal Dental and Medical Research Institute, Dehradun. The aim of this study is to compare the efficacy of three Aluminium Chloride based gingival retraction systems: Retraction cord , Astringent gingival retraction paste and Retraction paste system with comprecap in patients.
The main objectives of this study are :-
-
To compare the amount of lateral displacement and assess the changes in sulcus width by Retraction cord, Astringent gingival retraction paste and Retraction paste system with comprecap in patients.
-
To compare the amount of vertical displacement and to analyize changes in sulcus depth by Retraction cord , Astringent gingival retraction paste and Retraction paste system with comprecapin patients by clinically measuring with a flexible strip.
-
To compare the time taken for retraction by Retraction cord , Astringent gingival retraction paste and Retraction paste system with comprecap; the duration will be evaluated from the time of initiation of placement till the completion of placement.
-
To compare the haemorrhage after retraction by Retraction cord , Astringent gingival retraction paste and Retraction paste system with comprecap on the basis of haemorrhage score.

结局指标
主要结局
Vertical displacement (distance from CEJ to gingival margins in mm - sulcus depth) will be measured by three gingival retraction systems clinically.
时间窗: After retraction the sulcus depth( vertical displacement) will be measured at baseline with approximate duration of 30 minutes and sulcus width( horizontal displacement) will be measured microscopically from the casts obtained by baseline impressions.
Lateral displacement of gingiva achieved by three systems microscopically from the cast obtained by the die stones at baseline impressions.
时间窗: After retraction the sulcus depth( vertical displacement) will be measured at baseline with approximate duration of 30 minutes and sulcus width( horizontal displacement) will be measured microscopically from the casts obtained by baseline impressions.
次要结局
- The duration of time taken for placement of each retraction system can be evaluated by the time of initiation of placement till the time placement has been achieved. The duration of haemorrhage by each retraction system can be compared on the basis of haemorrhage score.(After retraction records will be measured at baseline with approximate duration of 30 minutes.)
