Pulp Polyp Exhibiting a Unique Worm-shaped Presentation in an Ectopic Deciduous Tooth: A Novel Case Report

Pulp polyp is a reactive lesion that occurs as a result of chronic long standing caries. Dental caries is common in children for a variety of reasons, including increased bacterial colonisation, frequent exposure to dietary sugars, improper bottle feeding technique, low community water fluoride levels, inadequate tooth brushing, and a lack of parental knowledge about oral health. Failure to treat such carious lesions during childhood will result in chronic long-term caries leading to pulpal necrosis or reactionary proliferations of pulpal tissue known as pulp polyp. Apart from caries, trauma can also lead to hyperplastic behaviour of the pulp. Pulp polyps are most commonly found in the molars due to their abundant blood supply, whereas their presence in the anterior teeth is considered uncommon. Pulp polyp can cause anxiety among parents when they spot it in their child's oral cavity. This is due to the unique clinical appearance, discomfort while having food and occasional bleeding while irritated. This case report presents an unusual presentation of pulp polyp in an 11-years-old female patient with a chief complaint of pain, discomfort, and bleeding on irritation. Its peculiar worm-shaped clinical appearance in the anterior attached gingival region imposed a diagnostic dilemma which on histological examination was confirmed to be pulp polyp and was excised subsequently. Therefore, emphasises the fact that pulp polyps are not only limited to the occlusal surface of posterior teeth with a typical mushroom-shaped appearance but also have a wide range of presentations regardless of their location and appearance.

Automated summary

Pulp polyp is a reactive lesion that can occur as a result of chronic caries or dental trauma. It is commonly found in molars and rarely in anterior teeth. This case report presents an unusual presentation of pulp polyp in an 11-year-old girl, causing pain, discomfort, and bleeding on irritation. The unique worm-shaped appearance posed a diagnostic dilemma, but was confirmed through histological examination.
