Abstract
Background
No long-term dental studies have been conducted on tooth eruption in patients with Trisomy 9p syndrome.
Case presentation
We report a case of a child with a duplication restricted to p24.3 of chromosome 9 and a severe delayed eruption of permanent teeth. Timely extraction of the deciduous teeth prevented the need for orthodontic treatment to address the impacted permanent teeth.
Conclusion
Achieving healthy dentition and occlusion can contribute to overall health, significantly enhancing the quality of life. Therefore, treatment strategies to allow the eruption of permanent teeth from an early age are crucial in this syndrome.
