Comparison of the Morphological Dimensions of Primary Molars with Kids Stainless Steel Crowns in a Sample of Iranian Children.
Aim: This study aimed to assess the morphological dimensions of primary molars in a sample of Iranian 4-9-year-old children for evaluating their compatibility with the size of Kids stainless steel crowns (SSCs).
Materials and methods: This descriptive-analytical cross-sectional research assessed 128 maxillary and mandibular primary molars of boys and girls presenting to the Pediatric Dentistry Department of Isfahan University of Medical Sciences in 2020. Impressions were made with silicone impression material, and the mesiodistal (MD) and buccolingual (BL) dimensions of upper and lower primary molars and the Kids SSCs were determined using a digital caliper accurate to 0.01 mm.
Results: The differences were insignificant between the upper first molars and SSCs in MD and BL widths (p > 0.05). The MD (p = 0.027) and BL (p < 0.001) dimensions of the Kids SSCs were significantly larger than the corresponding values in upper second molars. The difference in MD width was not significant between the lower first molars and SSCs (p > 0.05); however, the BL width of the SSCs fell significantly below that of lower first molars (p < 0.001).
Conclusion: The MD and BL dimensions of the Kids SSCs perfectly matched those of upper primary first molars. High compatibility was also noted between the MD width of SSCs and lower first molars and the BL width of SSCs and mandibular second molars. However, the MD and BL dimensions of SSCs were significantly larger than upper second molars.
Clinical significance: The findings indicate that Kids SSCs showed significant dimensional adaptation with the primary teeth in Iranian children and can be used as an alternative for 3M crowns. The best adaptation of Kids SSCs was seen in the upper primary first molars, and the least adaptation was seen in the upper primary second molars.

期刊介绍：
The Journal of Contemporary Dental Practice (JCDP), is a peer-reviewed, open access MEDLINE indexed journal. The journal’s full text is available online at http://www.thejcdp.com. The journal allows free access (open access) to its contents. Articles with clinical relevance will be given preference for publication. The Journal publishes original research papers, review articles, rare and novel case reports, and clinical techniques. Manuscripts are invited from all specialties of dentistry i.e., conservative dentistry and endodontics, dentofacial orthopedics and orthodontics, oral medicine and radiology, oral pathology, oral surgery, orodental diseases, pediatric dentistry, implantology, periodontics, clinical aspects of public health dentistry, and prosthodontics.
