Many variations in crown morphology are seen. The most common among these are accessory cusps present on the crown surface. These accessory cusps most commonly occur on the molars (cusp of Carabelli), incisors (Talonʼs cusp) and premolars (Leongʼspremolar). To date, the dental literature has reported very few cases with a morphological variation on the mesio-buccal cusp of the deciduous molars. We herein present 2 cases where we observed an extra cusp on the buccal surface of the deciduous maxillary first molar adjacent to the mesio-buccal cusp. A groove separates this cusp from the mesiobuccal cusp. This cusp was present bilaterally in one case and unilaterally in the other.Presence of this anomaly may necessitate modification of treatment plans and treatment procedures in children.
