Deep Margin Elevation Vs Crown Lengthening

Biological Evaluation of Indirect Restorations in Endodontically-treated Posterior Teeth With Deeply Located Proximal Margins Following Deep Margin Elevation Versus Surgical Crown Lengthening: A Randomized Controlled Trial

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 20 (actual)
• Sponsor: Cairo University · Academic / Other
• Sex: All
• Age: 18 Years – 40 Years
• Healthy volunteers: Accepted

Summary

The present clinical trial will be conducted to reject or accept the null hypothesis that in endodontically treated posterior teeth with deeply located proximal margins, will the Deep Margin Elevation will have better results from surgical crown lengthening in terms of biological criteria?

Conditions

• Endodontically Treated Teeth

Interventions

Type	Name	Description
PROCEDURE	Deep Margin Elevation using resin composite	After completion of the root canal treatment of the offended tooth and comprehensive evaluation of the obtained treatment, the randomly allocated patients will undergo deep margin elevation procedure where rubber dam isolation will be accomplished Followed by proper matricing and wedging ) followed by selective enamel etching for 10 seconds then universal adhesive application following the manufacturer instructions followed by application of flowable resin composite for the first 1 mm and light cured for 20 seconds according to the manufacturer recommendations followed by application of packable bulk fill composite to elevate the margins and light cured following the manufacturer instructions.
PROCEDURE	Surgical Crown Lengthening	Participants in this group will undergo surgical crown lengthening in which an internal bevel incision will be done buccally and lingually followed by full thickness flap reflection using mucoperiosteal elevator, then interproximal bone removal will be done using end cutting bur to the planned position away from the margins by 3 mm. The flap will be displaced apically with apically positioned sutures. Postoperative instructions will be given to the patient aiming to control postsurgical complications including pain and swelling. Suture removal and assessment of the surgical site will be done after two weeks
