Objectives: This study compared the dimensions of two SSC brands with the dimensions of the maxillary and mandibular primary molars in order to determine the SSC with better adaptation in the Iranian population.

Materials and Methods: In this analytic cross-sectional study, 224 primary molars were evaluated. Impressions were taken and casts were poured with dental stone casting material. Teeth were divided into 4 groups: the upper first molar, the upper second molar, the lower first molar, and the lower second molar. Then, each group was divided into left and right subgroups. Mesiodistal (MD) and Buccolingual (BL) dimensions of teeth were measured using a digital caliper with 0.01 mm accuracy. MD and BL dimensions of SSCs from two different brands (MIB and 3M) were also measured. The acquired dimensions of teeth and the related crown were compared. Data were assessed using an independent t-test at a significance level of 0.05.

Results: The greatest and least MD dimensions respectively belonged to the lower second molar and upper first molar. Also, the greatest and least BL dimensions respectively belonged to the upper second molar and lower first molar. The similarity of teeth and the SSC dimensions were better in the MIB group than in the 3M group. The similarity of teeth and the SSC dimensions were significantly different based on gender in the maxillary left second primary molar (MD), maxillary right first primary molar, mandibular left first primary molar, maxillary right second primary molar and mandibular right second primary molar (BL).

Conclusion: MIB crowns are recommended over 3M crowns as in most cases MIB has similar dimensions to primary molars of the Iranian population.
