The relative sharpness or cuspid prominence of incisors, canines, and sometimes premolars constitutes a variation in dental morphology. Prominent cusps and incisal edges can be observed in individuals and may be attributed to a variety of factors, including genetics, developmental influences, and tooth wear patterns. The extent of cusp development is considered a normal variation within the spectrum of human dentition.
Understanding the causes and potential implications of cusp prominence is important for dental professionals in the context of diagnosis, treatment planning, and patient education. While often a benign characteristic, exaggerated cusp development can occasionally contribute to occlusal interferences, soft tissue irritation, or esthetic concerns. Historically, dental morphology has also been studied in anthropological contexts to understand human evolution and population diversity.
