Diagnosis
ReferenceDiagnosis
Z. Qiu and G. Storch 2000Large-sized; M1 and M2 of subequal size. Occlusal outline of M1 and M2 square. Protocone and hypoconeof M1-3 inflated. Two strong lophs (protolophule I and II) on M2-3, connecting paracone with anterior and posterior arm of protocone. Sinus wide mesiodistally on M1 and well developed on M2; M3 with shallow protoflexus and sinus. Tendency to develop longitudinal spurs on meso-, meta-, and posteroloph of M1-2. Ectolophid of m1-2 oriented parallel to long axis of tooth. m1 without distinct mesoconid, reduced anteroconid, inflated hypoconid, and connection between protoconid and ectolophid. m3 conspicuously tapering posteriorly, with strong connection between metaconid and mesolophid and reduced posterolophid.
