Objective: the study aimed to ascertain the pattern and the prevalence of partial edentulism among Egyptian patients.
Materials and Methods: An observational cross-sectional study was conducted by screening patients attending out-patients clinics of three prosthodontics departments of dental faculties in Egypt. The prevalence of partial edentulism among all patients was recorded. Patients were grouped into four groups according to the age into Group I: 21–30 years, Group II: 31–40 years, Group III: 41–50 and Group IV: over 50 years. The pattern of partly edentulous arches was identified using Kennedy's classification. To eliminate the complexity, the assessment did not consider the modification areas. Data was analyzed using IBM SPSS Statistics for Windows, Version 23.0: IBM Corp.
Results: Kennedy Class I partial edentulism was 30.92%,(17.83 ,13.09) in the mandible and the maxilla, followed by class III that was 30.73%,(17.73 ,13.00) in the mandible and the maxilla, followed by class II that was 27.11%,(15.60 ,11.51)in the mandible and the maxilla,and finally class IV was 11.23%,(6.04 ,5.20)in the mandible and the maxilla and Kennedy's Class III was the most common partially edentulous pattern (11.05 %,9.56%) between ages (20-30 and 31-40) years , Kennedy's Class I,II was the most common partially edentulous pattern (12.81 %,7.99 %) (11.33%,9.10%,) between ages (41-50)(over50) years.
Conclusions: With increasing age, there is a rise in Classes I , II ,IV Kennedy classification and a drop in Classes III. Class III was more prevalent in the younger population, but Class I was more prevalent in elder patients.
