The mandibular second molar is the tooth located distally (away from the midline of the face) from both the mandibular first molars of the mouth but mesial (toward the midline of the face) from both mandibular third molars..
Most mandibular first molars have five cusps, and most mandibular second molars have four cusps.
The mandibular first molar has the largest mesiodistal dimension of any tooth.Sep 12, 2021.
Mandibular second premolars have three cusps.
There is one large cusp on the buccal side (closest to the cheek) of the tooth.
The lingual cusps (located nearer the tongue) are well developed and functional (which refers to cusps assisting during chewing)..
Mandibular second molars usually have two roots with three root canals, two in the mesial root and one in the distal root; however, these teeth can present severe anatomical variations, such as the presence of three canals in the mesial root, two canals in the distal root, or supernumerary roots [2].Sep 1, 2021.
The mandibular second molar is the tooth located distally (away from the midline of the face) from both the mandibular first molars of the mouth but mesial (toward the midline of the face) from both mandibular third molars.
This is true only in permanent teeth..
The mandibular second molar resembles the mandibular first permanent molar, except that the primary tooth is smaller in all its dimensions.
The buccal surface is divided into three cusps that are separated by mesiobuccal and distobuccal developmental grooves.
The cusps are almost equal in size..
A mandibular second premolar has a single root and root canal in the majority of the population [5].
The second premolars have only one root canal at the apex in 97.5% of the teeth and two canals in only 2.5% [6, 7]..
