The Effect of Functional Crown Lengthening Versus Deep Margin Elevation on Periodontal Tissues
20 participantsStarted 2026-02-01
Plain-language summary
The present study will evaluate and compare the effect of functional CL and DME in the treatment of posterior teeth with class II caries clinically and on the level of TNF-α in the GCF of treated teeth.
Clinical evaluation of periodontal tissue in the form of probing depth as a primary outcome, clinical attachment level, plaque index, bleeding index, gingival index, pink aesthetic score, Radiographic evaluation of biological width and the level of TNF-α in the GCF as a secondary outcome.
