About

management of endodontically treated first permanent molar with deep dental caries is one of the challenging procedure that the operator face. Using resin endocrown or stainless steel crown restoration to make comparison which one is more successful in children.

Full description

Diagnostic procedure:

Diagnosis of the cases will be performed according to guidelines of AAPD 2017 for treatment of irreversible pulpitis and necrotic pulp therapy in mandibular first permanent molar . Preoperative periapical radiograph will be taken

Intra operative procedure:

Local anaesthesia administration using articaine 4% with epinephrine 1:100000. Rubber dam application and access cavity preparation will be established using a sterile bur. Root Canal Treatment will be done and then the dental orifices of the pulp chamber will be sealed using a flowable composite.

The immediate postoperative radiograph will be done to reveal optimal root canal treatment.

In the intervention group:

The preparation of cavity design will be as following:

Preparation of occlusal surface will be done with wheel stone to create 2 mm occlusal clearance; the occlusal surface will be prepared flat to create a butt-joint. The junction between the occlusal and mesial cavity will be rounded to produce cervical side walk. • Divergence of the inner cavity walls will be obtained using a tapered stone with a rounded end (TR- Dia Bur Mani).

Impression will be taken for the prepared tooth structure using addition silicone material (Elite HD Zermach, Italy), stone model will be poured for fabrication of endocrown to allow for blockage of any undercuts in the pulp chamber cavity. Finished final endocrown restoration will be cemented in place using self-adhesive universal dual cured resin cement (rely X Unicem, 3M, USA).

In the control group tooth preparation will be made as follow:

By reducing mesial, distal and occlusal surface. The crown margin will be placed just apically to the gingival margin and carefully adjusted to give an accurate fit in this region. The crown will be cemented with glass ionomer cement.

Follow up:

Clinical and evaluation will be performed at 1 st week, 3, 6, 9 and 12 months. Radiograph evaluation will be performed at, 1 st week, 6 and 12 months
