It is important to diagnose DE early and provide appropriate treatment to help prevent periodontal disease, caries, pulpal complications and malocclusion. It occurs on the cingulum/occlusal surface of the teeth. The extra cusp can cause occlusal interference, displace of the affected tooth and/or opposing teeth, irritates the tongue when speaking and eating and decay the developmental grooves. Temporomandibular joint pain could be experienced secondarily due to occlusal trauma caused by the tubercle. This cusp could be worn away or fractured easily. In 70% of the cases, the fine pulpal extension were exposed which can lead to infection, pulpal necrosis and periapical pathosis.
