sps from each other. (e) mesiodistal developmental grooves extend toward the mesial and distal marginal ridges. (f) the mesial marginal ridge also extends toward the occlusal surface. (g) a mesial fossa may be present, with two supplemental grooves running toward the margin. (h) occasionally, these grooves traverse the entire marginal ridge, creating interruptions. these natural variations help avoid an artificial appearance in restorations. occlusal surface characteristics of the mandibular second molar (a) the occlusal surface has a relatively square-shaped appearance. m indicates the mesial side. (b) the central fossa is located near the center of the occlusal surface but appears slightly lingualized from an occlusal view. (c) grooves defining the four cusps radiate outward from the central fossa. (d) the mesial and distal marginal fossae, from which supplemental grooves emerge, are positioned approximately 1.5 mm from the marginal ridge. mandibular premolars occlusal features of the mandibular first premolar (a & …
