Current Primary Outcome Measures ICMJE |
The amount of irreversible gingival recession that might happen after gingival retraction. [ Time Frame: 4 weeks ] The amount of reversible and irreversible gingival recession (vertical gingival retraction) that might occur in healthy humans after placing retraction cords around prepared teeth for different periods of time. This will be measured after recording multiple digital intraoral scans pre-operative, 1 week, and 4 weeks post-operative using Medit i-700 then they will be superimposed using Medit Design tool (previously known as Medit compare) to track the vertical location of the gingival margin.

Official Title ICMJE | The Impact of Retraction Cords Used in Fixed Prosthodontics on the Gingival Margin Level in Humans: A Clinical Study. | ||||||||
Brief 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. | ||||||||
Detailed Description | Dental impression is the communication tool between the dentist and the dental technician during the fabrication of fixed dental prosthesis, capturing a precise impression of the prepared tooth and the finish line is mandatory to ensure the perfect fitting of the final prosthesis. Atraumatic gingival displacement is performed to provide sufficient both lateral and vertical space between the finish line and the gingival tissue that will allow recording adequate amount of unprepared tooth structure with the least distortion of impression material as well as minimal damage to attachment apparatus of the tooth as maintaining a healthy periodontium is an important factor in the survival of any fixed prosthesis. The gingival recession that might happen after soft tissue displacement may jeopardize treatment success in esthetic areas of the mouth. Knowledge about the soft tissue reaction to one of the most common gingival displacement methods (retraction cords) is critical yet limited. Also, there is a gap in knowledge about the safety of retraction cords when used for multiple teeth preparations and would then be left in the sulcus for an extended amount of time, as well as the potential harm they can do in terms of persistent gingival recession. The purpose of this study is to examine the relationship between placing specific retraction cords 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. This clinical study is expected to be useful for dental clinicians who use retraction cords during restorative procedures (cervical composite restorations) or for fixed prostheses; awareness about the amount of transient and permanent gingival recession that could occur is important to avoid undesirable effects such as esthetic issues and/or sensitivity. |
