Which teeth usually erupt first, the mandibular or the maxillary?( Modified from Zeisz RC, Nuckolls J: Dental anatomy, St game Louis, 1949, Mosby.) Facial (buccal) aspect ( mario Fig.The mesial marginal groove, a platinum branch of the central groove, lies between these two triangular grooves and sonar may cross the mesial marginal ridge of the crown.A maxillary third molar may have only three major cusps, or a mandibular third molar may have four major cusps.15.4 The buccal surface of a maxillary right first molar.The distobuccal root is straighter up and down than that of the maxillary first molar, and it has no mesial curvature.Therefore the oblique ridge runs from the tip of the mesiolingual cusp to manual world the tip of the distobuccal cusp.The hide minor cusps of the maxillary teeth are the distolingual cusps; those on the mandibular teeth are the distal cusps.Most dentists will try to save a tooth if it is possible; but there are some teeth that are just so badly damaged that the cost, time, and effort spent on restoration may not be worth the outcome.The distobuccal cusp usually forms a less obtuse angle where the mesial slope meets para the distal slope.The distal triangular fossa is mesial to the distal marginal ridge.Third Molars Evidence of calcification: 7 best years best Enamel completed: 12 to 16 years Eruption: 17 to 22 years Root completed: 18 to 25 years A maxillary third molar varies more than any other maxillary tooth in size, shape, and relative position to the other teeth. The cervical line is irregular and curved, generally toward the occlusal side at the mesial and distal ends.
Each has three well-developed major cusps and one minor cusp, all of which are functional.
