This study aims to identify the molars based on the width of the occlusal plane. The study was designed using a group design. The object of the study was the lower jaw bone (os mandibula) of CE goats aged three to four years without distinguishing gender. Measurements were also made on the maxillary molars (maxilla) from several skulls without mandibles of 14 each. Measurements were made on one side of the mandible (mandibular) or maxilla (maxilla) assuming symmetry. Measurements were done using a caliper. The target measured was the largest total width of the crowns of the I,2, and 3 molars (MMb11, MMb12; MMb21, MMb22, and MMb31, MMb32). The measurement data are recorded, tabulated, and presented in the form of mean and standard deviation. Size differences between molar width, molar notch, and molar plane were analyzed by two-way analysis of variance without interaction. The difference in width is significant if the test results have an error probability of less than five percent. If the test results are significant, it is tested with Duncan to see the difference in the pair at the five percent level. Conclusion, it was found that there was no difference in the indentation width between the molars, five of the fourteen molars examined, M1 showed no crypts.
