Summary

The purpose of this study is to examine the relationship between placing specific retraction cord for different periods of time and the post-operative gingival margin level in humans. Determining the amount of immediate reversible and delayed irreversible gingival recession (vertical gingival retraction) that might happen after placing a retraction cord around a natural tooth in healthy humans. It also aims to investigate the impact of mechanical and chemo-mechanical gingival retraction on periodontal health.

Conditions

  • Gingival Retraction
  • Gingival Recession
  • Periodontal Health

Interventions

PROCEDURE

Non-impregnated retraction cords/ less than 10 minutes

lower first molar will be prepared for full coverage restoration, plain retraction cord will be placed in the sulcus just before impression recording (less than 10 minutes).

PROCEDURE

Non-impregnated retraction cords/ more than 10 minutes

the preparation of the lower first molar for full coverage restoration will be initiated - occlusal reduction, contact points breaking, and preparation with the roughest bur- then a plain retraction cord will be placed and kept in the sulcus until finishing the preparation and impression recording which will take more than 10 minutes.

DRUG

impregnated gingival retraction cord - less than 10 minutes

lower first molar will be prepared for full coverage restoration, Aluminum chloride-impregnated retraction cord will be placed in the sulcus just before impression recording (less than 10 minutes).

DRUG

impregnated gingival retraction cord - more than 10 minutes
