Description
Diana Mohamed Amer and Abeer Mostafa Abdellatif (2024) measure how much a child's crowned tooth wears down the tooth it bites against. Baby molars matter for chewing and alignment, yet every crown material rubs its opponent. Forty lower second primary molars, in children aged four to eight, received one of four crowns. The options were stainless steel, a commercial prefabricated zirconia crown, a locally made CAD/CAM zirconia crown, and a locally made hybrid ceramic crown. The opposing upper teeth were scanned in 3D at fitting, six months, and one year.
Scanning the natural enamel opposite each crown turns wear into a number rather than an impression. Comparing four materials in living mouths, rather than on bench machines, shows which crowns are kindest to the teeth children must keep for years. Locally milled crowns are cheaper for clinics; this trial checks whether their wear behavior matches the imported brands.
