| It appears as a small bilateral papule with a distinctive location at the lingually attached gingiva, apical to the mandibular canine. |
| Lingually, these cusps are flat or slightly concave from apex to base, while their labial sides are convex along their height and in cross section. |
| A complete furcation closure was obtained lingually. |
| In lizards, actively foraging insectivores identify animal prey using lingually sampled chemical cues, but ambush foragers do not. |
| Access to the mesial furcations is best from the lingual surface because the furcation entrance is located lingually and not directly in the midline. |
| Lingually, this ridge crosses the paracone near its base and joins with the anterior cingulum. |
