distolingual การใช้

• Normally, maxillary molars have four lobes, two buccal and two mesiobuccal, distobuccal, mesiolingual, and distolingual lobes ).
• The two lingual lobes are separated by the distolingual groove, and the two buccal lobes are divided by the buccal groove.
• The lingual groove runs from the more distal of the central pits in the central groove toward the lingual surface between the mesiolingual and distolingual cusps.
• The groove pattern is shaped like a  Y with the tail pointed to the lingual and placed between the distolingual and mesiolingual cusps one third of the distance form the distal to the mesial.
• 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.
