Résumé
Many children with a habit of placing various objects in the oral cavity eventually end up with foreign body lodgement into the pulp chamber or root canal leading to pain and infection. This case reports babool thorn (Acacia nilotica) as foreign body in the root canals and the successful removal of thorns by nonsurgical technique and its management is presented. A 13 year old boy reported with chief complain of pain and swelling in an upper front tooth region since 1 month. A detail history elicited from the patient that he had suffered dental trauma 4½ years back. Both 11, 21 teeth were discoloured and non vital (Ellis Class IV #). During the biomechanical preparation, Babool thorns were accidentally found from 21, in total 12 babool thorns were recovered and both the teeth were further managed by successful apexification procedure with Biodentine (Septodont) followed by RCT and full crown restoration.
