Abstract

Instrument separation is a nightmare for dentists. It blocks the canal preventing further cleaning and shaping. This may lead to failure of root canal treatment. This case report presents successful management of instrument separation in mesiolingual canal of mandibular first molar. Retrieval of a instrument fractured below the curvature and extending periapically is a very difficult task. Ultrasonic technique along with dental operating microscope was used in this case. Keywords: Ultrasonics, Dental operating microscope, Instrument separation.

Abstract

Dens invaginatus is a rare malformation of teeth with a large variation in tooth morphology. Maxillary lateral incisors are the most commonly affected teeth. This article demonstrates management of maxillary central incisor with type II dens invaginatus (DI) with open apex and periapical lesion. Calcium hydroxide was used as intracanal medicament for apexification followed by obturation with guttapercha. CBCT (Cone Beam Computed Tomography) was used for diagnosis and treatment planning. One year follow up shows good periapical healing. Keywords: Dens Invaginatus, Calcium Hydroxide, Cone Beam Computed Tomography.
