Mandibular molar crown-topography, a biological predisposing factor to development of caries – a post-mortem analysis of 2,500 extracted lower permanent molars at the dental centre, University of Benin teaching hospital

  • IU Madukwe


The mandible molars are the biggest in the human mandibular arch. This study revealed susceptibility of different molar surface. A total of 2500 lower permanent molar teeth extracted and collected for teaching of oral biology were analyzed for caries attack. This number yielded a study crown surface area of 12,500 (5 crown surface per tooth). The result showed medical surface attack 1,572 (12.57%), distol surface attack 1,528 (12.22%) buccal surface attack 926 (7.40%), lingual surface attack 59 (0.47%) occlusal surface attack 6540 (52.32%). 1875 (15%) surface were unaffected. This studies will guide preventive health policies as regards clinical projections and management of carious attack in communities.
