Aim: The purposes of this study were to review all the studies that calculated the intermaxillary tooth-size ratios in Saudis, to review how gender and malocclusion groups influence tooth-size ratios, and to review the measurement methods for mesiodistal tooth width. Materials and Methods: MEDLINE, PubMed, Google Scholar, Saudi Dental Journal, and King Saud University Journal of Dental Sciences were searched for published studies reporting the intermaxillary tooth-size ratios of Saudis. No period of time for published studies was determined. The inclusion criteria were well-defined Saudi sample, reliable measurement method, and malocclusion classification determined for the study sample. Results: The searching process ended with five studies that met the final inclusion criteria. Gender and malocclusion groups are unlikely to have a significant influence on tooth-size ratios. Class III malocclusions cases have larger ratios. The anterior ratio and the overall ratio of Saudis seem not to be significantly different when compared with the Bolton results. Conclusion: All the studies that investigated tooth-size ratios in Saudis were conducted in major cities only. Until conducting more studies representing the overall population of Saudi Arabia, Bolton’s results can be used with caution for Saudi patients.
