The study was carried out to deduce the tooth occlusion pattern among the Hausas in Zaria, Nigeria. A total of 384 subjects made up of 184 males and 200 females within the ages of 20-49 years participated in this study. Data was collected by means of questionnaire. Results revealed that mild overbite type is the commonest (male = 33.6%, female = 32.6%) which was followed by edge to edge bite (male = 13.3%, female = 10.4%). The incidence of the severe overbite was observed more in males (3.4%) than females (2.1%). The incidence of negative overbite was observed more in females (2.9%) than males (1.8%). The results showed no significant gender difference (p≥0.05) in the tooth occlusion pattern. The tooth occlusion pattern of the Hausas in Zaria, Nigeria is such that some occlusion types are relatively more common in females than the male counterparts and vice versa. The mild overbite type of occlusion is the commonest among the Hausas in Zaria, Nigeria. The negative overbite is the least common tooth occlusion pattern among the Hausas in Zaria, Nigeria.

Background: Fracture is a commonly associated medical condition with osteological structures. It is caused as a result of high stress or impact forces acting on bone. This study is aimed at evaluating the types and prevalence of bone fractures in Celian Clinic, Ughelli in Delta State, Nigeria. Materials and Methods: This survey is a one-year retrospective study which comprised 256 patients (160 males and 96 females) managed at Celian Clinic. Ethical Consent was obtained from the Research and Ethics Committee of Human Anatomy and Cell Biology Department, Delta State University, Abraka. Data were sourced from the Orthopaedic Department and patient’s information such as age, sex, cause and bones fractured. Data were analysed and chi-square test used in evaluating relationship between variables. Results: Findings showed males (62.5%) having a higher prevalence of facture than females (37.5%). It was also observed femur (19.9%) was the most prevalent bone fractured which was followed by tibia/fibula (16.0%). Findings also indicated individuals within the ages of 21-40years (37.9%) was the most affected followed by age group of 41-60years (29.3%). Results also showed road traffic accidents (62.5%) were the most predominant causes which was followed by fracture with unknown aetiology (19.9%) with the least causative factor being assault (2.0%). Significant association with a p-value of 0.004 was observed in a test of association between age and class of bone fracture. Conclusion: In conclusion it was observed that bone fractures had a higher predisposition to the male gender (62.5%) than the female (37.5%) with its commonest etiological factor being road traffic accident (62.5%).
