Author(s): Inchara R and Karthickraj SM*
Finish line exposure has to be adequate during impression making. The goal of gingival retraction is to a traumatically displace gingival tissues to allow access for impression material to record the finish line and provide sufficient thickness of gingival sulcus so that the impression does not tear off during removal. Supra-gingival margins are effective in periodontal health maintenance, but do not provide optimal aesthetics. The current study aims at evaluation of finish line exposure with retraction cord placement in esthetic procedures in Saveetha dental college and hospitals from April 2020 to February 2021. Materials and Method: It is a single cantered retrospective study conducted in a private dental institution, Chennai. The data was collected from the dental hospital management system. The data included a varied population predominantly south Indian. All the details of the patients from April 2020 to Feb 2021 were collected. The internal validity included diagnosed cases as per criteria, medical history, chief complaints and clinical findings. Inclusion criteria include patients above age of 18, type of finish line and finish line exposure in patients who had undergone veneers. Exclusion criteria include presence of systemic disorders, type of material used for veneers. Results: In the current study, it was found that subjects aged 19 to 25 and 26 to 30 had superior finish line exposure with retraction cord placement than subjects of other ages, which was statistically significant and there was no statistically significant difference in finish line exposure with retraction cord positioning between males and females. Conclusion: Within study limits, it is concluded that intermediate exposure of the finish line was observed more in all the patients who underwent esthetic procedures.
