Abstract

Background: Oral biology deals with development, structure, and functions of oral tissues, their interrelationship and relationship with other tissues/organs in health and disease. This study was on the collected human specimen for teaching of oral biology to dental students.


Methodology: 2,765 teeth were collected from the Department of Oral Surgery and Pathology, University of Benin and Department of Oral Pathology and Oral Biology, University of Port-Harcourt. These teeth were preserved in 10% formalin bottle. The teeth were collected over 10-year period and were sorted by tooth-type into deciduous and permanent teeth, using size, shape, colour and specific tooth indices as parameters. Deciduous teeth were sorted into deciduous anteriors and molars. The tooth-type was sorted into carious, periodontal disease, avulsion, and exfoliated teeth. Avulsion due to assault related and crime cases were excluded to avoid spuriousness. Result: Study revealed that posterior teeth (67.5%) were lost, more than anterior teeth (32.5%). Sorting by tooth-type
showed greater mortality of the molars; deciduous molars (4.52%) and permanent molar (48.98%). Dental caries was the main cause of tooth mortality (50.02%); followed by periodontal disease (41.52%), Avulsion contribution was (6.51%) and least was exfoliation (1.7%).
Conclusion: Dental specialist have important positive role in improving dental education, oral health practices, stimulating dental research and defining quality expectations in their areas of expertise.
