Diagnosis
ReferenceDiagnosis
H. Erten 2017The occlusal surface exhibits complete stephanodonty. The cusps t1, t2 and t3 have strong connections on M1. A connection in the form of a longitudinal crest exists between t1-t5 and t3-t5. A strong and garland-type connection exists between t4-t5-t6-t9-t8 and t7 or t4-t7 connection is absent while the other cusps are strongly connected. A cir- cular island shaped neoenterostyle is observed in the lingual part of the tooth. tma is absent on m1, and c1 and c2 are connected to each other (Figure 3).
