- In dentistry, a Bolton discrepancy refers to a significant size difference between the upper and lower teeth1. The discrepancy is determined using a Bolton analysis, which calculates the ratio of the mesiodistal widths of the maxillary teeth to the mandibular teeth2. A ratio greater than 91.3% indicates that the mandibular teeth are larger than normal, while a ratio smaller than 91.3% indicates smaller mandibular teeth3. This analysis is important for proper dental health and aesthetics.
