The risks should be explained to patients and surgeons, and the treatment of these patients should be decided taking into consideration all the factors. Frequent visits to the dentist would be suitable for these patients sellckchem to emphasize the importance of extraordinary oral hygiene to prevent dental decay and periodontal disease.
Gemination is an uncommon anomaly caused by the incomplete attempt of a single tooth bud to form two teeth.1 Geminated teeth are found more frequently in primary dentition than permanent dentition.2�C4 The prevalence in the latter ranges from 0.07% to 2.1%.5�C7 Maxillary central incisors were found to be the most commonly affected by gemination.6,7 Gemination causes aesthetic problems, bad positioning, and impaction of adjacent teeth because of the greater volume of the geminated tooth crown.
8 Talon cusps are also uncommon dental anomalies manifesting as an accessory cusp-like structure projecting from the cingulum area or the cemento-enamel junction of a maxillary or mandibular anterior tooth in either primary or permanent dentition.9,10 The prevalence of talon cusps in permanent dentition differs among populations, ranging between 0.6% 7.7%.11�C16 The clinical problems associated with talon cusps include food stagnation; caries periapical lesions; tongue irritation; breast feeding problems; compromised aesthetics; occlusal interference, which may lead to accidental cusp fracture; displacement of the affected tooth; dental sensitivity, temporomandibular joint pain; and periodontal problems because of excessive occlusal force.
10,11,17 Even though talon cusp may occur in isolation, it may also be associated with other variations in crown anatomy, such as peg-shaped crown, supernumerary teeth, and dens invaginatus.10,18�C22 A talon cusp on a geminated tooth is a very rare finding. Five cases of unilateral geminated teeth with talon cusps20,23�C26 have been reported, and no cases of bilateral geminated teeth with talon cusps have been reported in the literature. This article aims to describe an unusual case of bilateral geminated teeth with talon cusps and the multidisciplinary treatment administered in this case. CASE REPORT A 17-year-old boy complained of poor dental aesthetics. He had no history of any severe illness or orofacial trauma, and his physical development appeared normal for his age.
Clinical examination revealed that the crowns of his maxillary central incisors were very large (Figure 1). Since he had a normal number of teeth, the shape anomaly of the crowns was attributed Dacomitinib to ��bilateral gemination.�� The mesiodistal diameters for the right maxillary incisor and left maxillary central incisor were 12.1 mm and 12.7 mm, respectively. The mesiodistal widths of the crowns were significantly greater in the incisal third than the cole region, which created a fan-like shape. Both central incisors had a distinct groove in the enamel that ran buccolingually.
