Prefabricated CAD/CAM PEEK Crowns For Primary Molars Restoration
Sponsor: Arab International University
Summary
This Split-mouth randomized clinical trial aims to evaluate CAD/CAM prefabricated Polyether ether ketone crowns for primary molars restoration after pulpotomy compared to Stainless steel crowns Over follow-up periods of 3, 6, and 12 months, the sample included 60 children aged 5-9 years who had bilateral mandibular second primary molars. Each child received a pulpotomy treatment followed by the placement of a stainless steel crown on one side and a PEEK crown on the contralateral side, distributed randomly. Clinical parameters were subsequently evaluated during the three follow-up periods, including the gingival index, plaque index, bleeding on probing index, restoration retention and integrity, marginal adaptation, color stability, and both parental and child satisfaction.

Interventions
Prefabricated CAD/CAM PEEK with 0.2 mm thickness
The pulpotomized molar assigned to experimental group will be received A Polyether ether ketone prefabricated crown with 0.2mm thickness on one side of mandibular arch, and the other side will be received a Stainless steel crown as control group.
Prefabricated CAD/CAM PEEK with 0.4 mm thickness
The pulpotomized molar assigned to experimental group will be received A Polyether ether ketone prefabricated crown with 0.4mm thickness on one side of mandibular arch, and the other side will be received a Stainless steel crown as control group.
CAD/CAM-fabricated PEEK Crowns
The pulpotomized molar assigned to experimental group will be received A CAD/CAM fabricated Polyether ether ketone crown on one side of mandibular arch, and the other side will be received a Stainless steel crown as control group.
Satinless steel crowns
The pulpotomized molar assigned to control group will be received a Stainless steel crown as control group on one side of mandibular arch, and the other side will be received one of the arm 1, 2, or 3
