It is mesial from both mandibular lateral incisors. The mesial and distal contacts are more cervical than the central incisor. Epilepsy of the mesial temporal lobe is associated with HHV-6 infection. Premolars are found distal to canines and mesial to molars. BPOP is located in the parasagittal and mesial regions of the parieto-occipital cortex. The abutment tooth may be mesial or distal to the pontic. Along the mesial and distal sides are slightly raised portions called marginal ridges. The mesial view shows a slight tipping of the crown to the lingual. The mesial incisal angle is sharper than the distal incisal angle. The distal and mesial marginal ridges are evident and the cingulum is prominent. Their mesial and distal proximal contacts are located in the incisal third. A common associated brain abnormality is mesial temporal sclerosis. There are two marginal ridges, mesial and distal, present on all teeth. Furcation involvement should be checked from the mesial and the distal aspects of the tooth. The words mesial and distal are also used as descriptions.
