What is the relationship between overbite and overjet in primary dentition?

  1. Significant overbite and increased overjet

  2. Minimal overbite and anterior edge-to-edge

  3. No overbite and no overjet

  4. Deep overbite and deep overjet

The correct answer is: Minimal overbite and anterior edge-to-edge

In primary dentition, the relationship between overbite and overjet is best understood as minimal overbite and anterior edge-to-edge. This option refers to the ideal relationship between the horizontal and vertical overlap of the upper and lower teeth in primary dentition. Options A and D describe more severe overbite and overjet relationships, which may indicate malocclusion or misalignment of the teeth. Option C is also incorrect as it describes no overlap of the upper and lower teeth, which is not possible in normal occlusion. Therefore, option B is the correct answer as it accurately describes the relationship between overbite and overjet in primary dentition.
