Background: We conducted research to investigate the effects of the eruption sequence of
posterior teeth, arch dimensions, and incisor inclination on dental crowding. Material and Methods:
A cross-sectional analytic study was performed on 100 patients (54 boys and 46 girls; mean ages: 11.69
and 11.16 years, respectively). Seq1 (canine-3-/second premolar-5-) or Seq2 (5/3) eruption sequences
were recorded in maxilla, and Seq3 (canine-3-/first premolar-4-) or Seq4 (4/3) eruption sequences
in mandible; tooth size, available space, tooth size-arch length discrepancy (TS-ALD), arch lengths,
incisor inclination and distance, and skeletal relationship were noted. Results: The most common
eruption sequences in the maxilla and mandible were Seq1 (50.6%), and Seq3 (52.1%), respectively.
In the maxilla, posterior tooth sizes were larger in crowded cases. In the mandible, anterior and
posterior tooth sizes were larger in crowded patients. No relationship between incisor variables and
the maxillo-mandibular relationship and dental crowding was found. A negative correlation between
inferior TS-ALD and the mandibular plane was found. Conclusions: Seq1 and Seq 2 in the maxilla
and Seq 3 and Seq 4 in the mandible were equally prevalent. An eruption sequence of 3–5 in the
maxilla and 3–4 in the mandible is more likely to cause crowding.
