PDF: Dentoalveolar Abscess in a First Molar Eruption: A Rare Case of Pericoronitis Progression



Erupting permanent mandibular first molars typically go unnoticed in the absence of pathology, yet their unique anatomical and developmental context places them at a clinically important cusp of risk.

In the article titled “Dentoalveolar Abscess Caused by Pericoronitis of an Erupting First Molar”, the authors present a compelling case of a 7-year-old patient who developed a dentoalveolar abscess originating from pericoronitis around an erupting first molar.


In most paediatric settings, pericoronitis is observed around third molars and tends to resolve spontaneously or with minimal intervention.

However, in this report, the sequence evolved into a bone-defect-associated abscess confirmed by cone-beam computed tomography—despite an initially normal panoramic radiograph.

The significance of this finding cannot be overstated: it underscores the necessity of heightened vigilance during the eruption phase of first molars, incorporation of advanced imaging modalities where clinically justified, and reinforced oral hygiene strategies among younger patients whose manual dexterity may not yet be sufficient for effective plaque control.


For clinicians in paediatric dentistry, general practice and interdisciplinary care, this case serves as a timely reminder that eruption-associated soft-tissue inflammation may occasionally precipitate more complex sequelae.

Early recognition, appropriate imaging, surgical-interventional management and educational measures for guardians and children are integral to optimal outcomes.

👉 Dear dental professionals around the world: we invite you to Read the full open-access article in PDF format for a detailed exploration of the clinical presentation, imaging findings, surgical management and follow-up of this rare case.

This deeper insight will enrich your clinical acumen when managing erupting first molars and potential complications.
