# Spontaneous Eruption of Permanent Teeth That Had Eruption Disturbances After Extirpation of Odontomas: A Report of Two Cases

## TL;DR

This paper reports two cases where permanent teeth spontaneously erupted after removing odontomas, suggesting extraction timing may influence tooth eruption.

## Contribution

The study highlights new clinical observations on spontaneous tooth eruption following odontoma removal, challenging standard treatment assumptions.

## Key findings

- Two cases showed spontaneous eruption of permanent teeth after odontoma extirpation.
- Tooth eruption occurred without orthodontic intervention in these cases.
- The findings suggest reevaluating the criteria for tooth extraction timing.

## Abstract

Odontomas, often found adjacent to impacted teeth, are tumors of abnormal tissue morphology arising from the tooth germ and are usually asymptomatic. They are often found by accident on X-ray images, and the eruption of permanent teeth is often caused by odontomas. In most cases, the tooth is extracted with the permanent tooth or orthodontic treatment is performed after extraction. However, the criteria are not clear. We encountered two cases of dental eruption in which permanent teeth, which originally seemed to be suitable for orthodontic treatment, spontaneously erupted after odontoma removal. It is necessary to examine the indications and timing of tooth extraction.
