BACKGROUND Dens evaginatus, or DE, is an uncommon dental anomaly, in which an extra cusp or tubercle protrudes from the occlusal surface of posterior teeth, as well as the lingual surface of anterior teeth. Tubercles frequently are susceptible to fractures and pulpal complications. METHODS A 9-year-old Hispanic girl presented for six emergency visits over a five-week period. Her chief complaint was of pain associated with a maxillary primary second premolar. Clinically, the tooth appeared to be noncarious, but it had an abnormal-appearing root. It was extracted after the patient presented with a left facial cellulitis. CONCLUSIONS DE often challenges the practitioner with its frequent and early pulpal complications. The signs and symptoms in this case resulted in a difficult diagnosis and limited treatment options.

UI	MeSH Term	Description	Entries
D010482	Periapical Abscess	Acute or chronic inflammation of tissues surrounding the apical portion of a tooth, associated with the collection of pus, resulting from infection following pulp infection through a carious lesion or as a result of an injury causing pulp necrosis.

D003731	Dental Caries	Localized destruction of the tooth surface initiated by decalcification of the enamel followed by enzymatic lysis of organic structures and leading to cavity formation. If left unchecked, the cavity may penetrate the enamel and dentin and reach the pulp.

D003743	Dental Enamel	A hard thin translucent layer of calcified substance which envelops and protects the dentin of the crown of the tooth. It is the hardest substance in the body and is almost entirely composed of calcium salts. Under the microscope, it is composed of thin rods (enamel prisms) held together by cementing substance, and surrounded by an enamel sheath.

D003790	Dental Pulp Necrosis	Death of pulp tissue with or without bacterial invasion. When the necrosis is due to ischemia with superimposed bacterial infection, it is referred to as pulp gangrene. When the necrosis is non-bacterial in origin, it is called pulp mummification.

D001641	Bicuspid	One of the eight permanent teeth, two on either side in each jaw, between the canines (CUSPID) and the molars (MOLAR), serving for grinding and crushing food. The upper have two cusps (bicuspid) but the lower have one to three. (Jablonski, Dictionary of Dentistry, 1992, p822)	Premolar,Bicuspids,Premolars
D014082	Tooth Fractures	Break or rupture of a tooth or tooth root.	Fracture, Tooth,Fractures, Tooth,Tooth Fracture
D014092	Tooth Root	The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots.
