distobuccal การใช้

• The distobuccal groove runs from the distal pit in the central groove distobuccally separating the distal and distobuccal cusps.
• The distobuccal groove runs from the distal pit in the central groove distobuccally separating the distal and distobuccal cusps.
• Normally, maxillary molars have four lobes, two buccal and two mesiobuccal, distobuccal, mesiolingual, and distolingual lobes ).
• It is formed by the union of the distal cusp ridge of the mesiolingual cusp and the triangular ridge of the distobuccal cusp.
• The buccal groove runs from the more mesial of the central pits in the central groove toward the buccal surface between the mesiobuccal and distobuccal cusps ending in the buccal pit.
• Viewed from the top of the tooth ( occlusal view ), the mandibular first molar is pentagonal ( five sided ) in shape and tapers toward the lingual, with the sides being the buccal surface, the mesial surface, the lingual surface, distal surface, and the distobuccal surface.
• Anatomy : The mandibular first molar has five cusps : the mesiobuccal ( MB, toward midline and cheek ), mesiolingual ( ML, toward midline and tongue ), distolingual ( DL, away from midline and towards tongue ), distobuccal ( DB, away from midline and toward cheek ), and distal ( D, away from midline ), listed in order of decreasing size.
