rooth surfac edepression on the max 1st molar posses a concavity travelling from C/3 of crown on to root surface... which 1 is this.../L/M/F/ DB/ DL:confused:.. i thing it be DL what say.???

21.primary molar having a transverse rodge, oblique ridge and a disto lingual groove is Max 2nd(anss:confused:) / or Mandb 1st...??/(Transverse ridge in lower 1st molar / DL in Max 2 nd and oblique ridge in Max 2... am i rigth... ) how cum????

51/ crown outline of mand 2 nd molar is ...... square:confused: / pentagonal(ans).. but i think it shld ne square .. what say????

K/ 2/29. IN CROSS SECTION THE PULP CHAMBER IS ROUND IN Max CI/ Max LI/ Mand CI:confused:/ Mand Canine i think it be mabd CI... what say guys??????

R/4/3. from the buccal aspect Mand 2nd molar typically has a enamel crevical extension centerally on the root trunk.. T/F

6/13. opposing occlusal contacts in CO occurs in deglutation / respiration/ mastication/ clenching/ incising.... which oneS....???

8/18. in normal arrangement of teeth which is a proximal surface all mesial and disatl surfaces T:confused:/F

MAND{{largets to smallest.. MB ML DL DB D}}
MAX {{ ML MB DB DL}}correct or not??

structures exhibited by mand Incisors are allexcept. marginal ridges:confused: / lingual fossa/ imbrication lines IL(i read in some previous post that the ans is IL.... but these are present in all teeth..????)

Incremental lines in the dentin and cementum of the tooth reflect variations in mineralisation during dentin formation


Mandibular Central Incisor
Facial: The mandibular central incisor is the smallest tooth in the dental arch. It is a long, narrow, symmetrical tooth. The incisal edge is straight. Mesial and distal outlines descend apically from the sharp mesial and distal incisal angles.
Lingual: The lingual surface has no definate marginal ridges. The surface is concave and the cingulum is minimal in size.
Proximal: Both mesial land distal surfaces present a triangular outline. Incisal: The incisal edge is at right angles to a line passing labiolingually through the tooth reflecting its bilateral symmetry.
