Children have a habit of ingestion or aspiration of foreign object, which pose severe danger to the child as well as parents. However the insertion of objects into the tooth is not very common and most of the time parents are unaware as children fear to reveal. Such objects act as a site of infection and may lead to discoloration of the tooth as well as abscess.

In the present case child presented with a discoloured maxillary right lateral incisor. Radiograph revealed presence of a metallic object inside the root canal of the same tooth, which neither the patient was aware nor the child disclosed during history taking. Hence early diagnosis and treatment is necessary to avoid future dreadful situation to child as well as patient. Parents should also be instructed to maintain a nonjudgmental and non-authoritarian approach to handle children, so that kids won’t be fearful to discuss their problems.

Accidental ingestion of foreign body by children is a pediatric emergency. It causes panic for children as well as parents. Children have a tendency to ingest marbles, toys, coins, keys and pins [1]. However insertion of foreign body in tooth by children is highly uncommon phenomenon. Open carious tooth in oral cavity acts as a site for insertion of foreign body leading to pain, swelling and abscess [2]. Proper history, detailed clinical examination and radiographs are necessary to detect the cause and give an appropriate diagnosis. A radiograph is also necessary to detect the correct size, type and position of the foreign object. This case report describes occurrence of stapler pin in deciduous maxillary right central incisor and its subsequent management.

Case Report

8-year-old girl with her parents reported to our dental department with the chief complaint of pain in upper right front teeth past one week. Parents also gave the history of pus discharge from the same tooth past three days. On clinical examination there was blackish discoloration on right deciduous lateral incisor i.e. 52. The pulp chamber of the tooth 52 was open with food lodgment (Figure 1). Labial vestibule in relation to the same tooth had a draining sinus (Figure 2). Intraoral periapical radiograph in relation to 52 showed a radiopaque twisted wire like unusual object in the pulp chamber as well as root canal (Figure 3). On enquiring the possible history of a metallic object inside the root canal parents mentioned that the child has a habit of putting stapler pins inside the mouth. As the permanent lateral incisor was erupting during the time of presentation of the case, we decided to extract 52 after informing the parents and taking their consent. Extraction was done under local anesthesia. After extraction the foreign object was removed from the tooth and it was found to be a stapler pin (Figure 4).
