Impact of DME on Pulpal and Periodontal Health at Varying Gingival Seat Level

The classical idea was to keep the biologic width untouched in order to maintain periodontal health but the newer case reports have given a new dimension to this concept, stating that a limited extension into STA can be used as an alternative for invasive procedures like SCL. The periodontal tissues can still tolerate subgingival margin placement in biologic width when restorations are free of overhangs which are real culprit for providing room for plaque retention and further inflammation. There are no sufficient clinical studies with good sample size to prove the significance of this concept. Hence, we are performing a Non Randomized Controlled trial by placing gingival margins at various levels above the alveolar crest and restoring it with composite and further evaluate the periodontal tissue health, pulpal health, restoration quality and significance of DME.

Rct Deep Margin Elevation by Self Adhesive Composite

This study intend to study the development and introduction of new efficient approaches to overcome the problems of technique sensitivity of deep margin elevation by conventional flowable composite. This new class of Self- adhesive composites that have been developed and were marketed as flowable, low viscosity resin composites does not require any etching or bonding strategy before cavity filling and the ability to wet and adapt easily.The procedure is simplified by eliminating the adhesive application, which is the most technique sensitive step. (Fu J, Kakuda S, Pan F, e t al. 2013). DME addresses multiple clinical problems associated with sub-gingival margins which pose a challenge due to limited access, rubber dam slippage over the margin and subsequent persistent saliva, crevice fluid and blood leakage. There are uncertainties within the profession in providing DME, and it is still considered a new approach. A recent survey revealed 78% of dentists had more than one concern about the procedure, ranging from isolation and inspection, marginal adaptation, microleakage. (Taylor, Burns, 2024) FIT SA™, a new comprehensive self-adhesive flowable restorative with bioactive Giomer Technology inside. FIT SA has eliminated the need for the technique sensitive bonding procedure. FIT SA offers superior strength and polishability, and the unique filler structure combines the light transmission and diffusion properties of enamel and dentin to blend well withthe surrounding dentition.

The Effect of Bulk Filling Flowable Composite on Caries Recurrence in Deep Marginal Elevation: A Randomized Clinical Trial

Deep marginal elevation usinge a bioactive dental material in deep subgingival Class II restorations, S-PRG filler-containing materials offer significant benefits due to their bioactive properties, Their ability to release fluoride, remineralization potential and acid neutralization, reducing the risk of recurrent caries, particularly at the gingival margin(Imazato et al. 2023). The antibacterial and antifungal effects help inhibit biofilm formation, enhancing the longevity of restorations. Additionally, these materials support better marginal adaptation by reducing microleakage and improving bond durability (Imazato et al. 2023) This type of composite may improve the outcomes of deep subgingival margin elevation, benefiting both restorative success and periodontal health(Imazato et al. 2023).

Clinical Performance of High Viscosity Bioactive Injectable Composite in Deep Marginal Elevation

Using a bioactive resin composite in subgingival Class II cavities can provide enhanced caries resistance by releasing multiple ions, including fluoride. This approach offers greater resistance to caries due to the incorporation of surface pre-reacted glass filler (S-PRG) technology (Imazato, Nakatsuka et al., 2023). This type of composite may improve the outcomes of deep subgingival margin elevation, benefiting both restorative success and periodontal health.
