  2. 2. Dr. Rooban Thavarajah Deciduous Dentition Maxillary teeth Mandibular teeth
  3. 3. Dr. Rooban Thavarajah Mandibular Lateral Incisors  ~ central incisor but larger  Wider and longer than central incisors  Cingulum more developed than central incisors  Root of mandibular lateral incisor is longer, narrower and more tapered than that of the central  Less blunt at apex than mandibular central  Mesial depression on lateral incisor only  Distal longitudinal groove lateral incisor only
  4. 4. Mandibular Lateral Incisors  From labial or lingual aspect, incisal outline slopes slightly toward distal, with a resultant distoincisal angle which is more rounded, as is distal margin of crown.  Distal margin is also a little shorter.  Cingulum and marginal ridges are usually a little larger, and lingual fossa is a little deeper. Dr. Rooban Thavarajah
  5. 5. Mandibular Lateral Incisors  From incisal, crown is not quite symmetrical like the central, since cingulum bulges toward distal  Root may present a distal curvature in its apical third & has a distal longitudinal groove Dr. Rooban Thavarajah
