Dens invaginatus is a condition which occurs as a result of invagination of the enamel organ and the reported prevalence of adult teeth affected is 0.3-10%. It frequently leads to pulpal and periodontal involvement due to bacterial microleakage which can be challenging to diagnose and treat due to unusual canal morphology. This case study looks at the sequalae and management of endodontic infection in an immature, maxillary left lateral incisor (UL2) with dens invaginatus. A 19-year-old male was referred by his dentist due to recurrent buccal swellings and a sinus tract associated with the UL2. The patient reported no history of trauma and at examination was asymptomatic, but recalled having one course of antibiotics in the past. The UL2 had a palatal fissure sealant and had no mobility, periodontal pocketing, tenderness or discoloration. The response to pulp sensibility testing was negative and a periapical radiograph revealed a large periapical radiolucency associated with the UL2, an open apex and immature root formation. A diagnosis of UL2 necrotic pulp and Chronic Apical Abscess was made. Primary root canal treatment was performed under a split dam technique using ProRoot MTA as an apical plug and thermo-plasticized gutta percha for obturation. Knowledge of advancements in endodontic materials is important for all practitioners advising patients of treatment options and gaining consent, therefore, this case aims to give an overview of the steps involved in the treatment of non-vital teeth with immature root formation and open apices. Current evidence based on various randomised controlled trials shows that MTA is associated with better outcomes compared to the traditional approach of apexification using calcium hydroxide. It provides the advantage of sooner apical closure and so limits the risk of coronal or radicular fracture. Should this treatment fail in the future, a surgical approach may be considered.

The Royal Gwent Hospital in Newport is providing an exciting new service that will allow patients to take advantage of innovative technology and avoid major surgery and hospital admission. The new service is for patients who are experiencing problems with their saliva glands and offers them the option of outpatient treatment.

In 2007 NICE endorsed these techniques in the management of salivary gland problems.
