Effect of extraction in the late mixed dentition on the eruption of the first premolar in Macaca nemestrina

Abstract

The effect of deciduous tooth extraction in the late mixed dentition on the eruption of succedaneous teeth was studied in ten Macaca nemestrina. Nineteen deciduous teeth were extracted: nine maxillary and ten mandibular left deciduous first molars. Regardless of sex, arch, chronologic or dental age, all first premolars on the experimental side erupted before those on the control side and this pattern was statistically significant. Extraction of deciduous molars in the late mixed dentition is seen to accelerate eruption of first premolars in Macaca nemestrina. This could be the result of eliminating the need for deciduous tooth root resorption during the normal process of eruption.
