Prefabricated CAD/CAM PEEK Crowns For Primary Molars Restoration

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.
