Efficacy of Conventional versus Cordless Displacement System on Gingival Retraction for Use with Intra-Oral Scanner: A Clinical Study

A BSTRACT Aim: The present clinical study aimed to assess the efficacy of conventional versus cordless displacement systems on gingival retraction for use with an intra-oral scanner and changes in periodontal indices. Materials and Methods: A total of 20 participants were selected for a split-mouth study (20 sites – Group Sc, 20 sites – Group Es). The outcomes were measured at day 0, day 1, and day 7 of follow-up in terms of Immediate horizontal displacement, Plaque Index, and Bleeding Index. Unpaired and Paired t -test was used as the parametric tests and statistical analysis was performed. Results: A statistically significant change was observed in terms of BI on day 0, but no statistically significant change was observed for either group in terms of IHD and PI. Conclusion: The cordless material caused the least trauma to gingival tissue and was more compatible with intra-oral scanning devices.
