Little of the mesial and distal surfaces may be seen from this aspect.
The mesiodistal dimension cervically is greater than that of the first molar.
2-The contact areas are more noticeable from this
aspect, and they are slightly more cervically
positioned than those of the first molar.
1-The buccal cervical ridge is less pronounced
compared to the first molar.
2-The mesial root has a somewhat pointed apex.
From this aspect, this tooth is similar in form to the first molar except for the absence of a distal cusp and The contact area is centered on the distal surface bucco-lingually and is centered between the cervical line and the marginal ridge.
1- The occlusal surface is rectangular in shape.
2- The small distal cusp is not present and there is no distobuccal groove.
3-The buccal and lingual developmental grooves meet the central developmental groove at right angles at the central pit. These grooves form a cross, dividing the occlusal surface into four parts that are nearly equal.
4- Unlike the first molar, the occlusal surface is not smooth but is roughened
by many supplemental grooves radiating from the developmental grooves.
