Aim: This study aimed to evaluate the prevalence of partial edentulism among patients
attending Faculty of Dentistry, Cairo University. Materials and Methods: This cross-sectional study included 362 partially edentulous patients
aged from 18 to 80 years. A recording sheet (a self-designed proforma) was utilized to gather data. Theprevalence of Kennedy's classification and which class was determined by a visual examination using the dental mirror while the patient was seated on a dental chair. Results: The recruited sample included a total number of 220 females and 142 males. There were 239 urban subjects and 123 rural subjects in total. 256 patients had partial edentulism in the
mandibular arch while 172 patients had partial edentulism in the maxillary arch. Total classes included 145 CI, 149 CII, 105 CIII, and 29 CIV. 63.3% of the patients lost their teeth because of caries. Conclusion: Within limitations of this study, class II was the most common in both dental
arches. Partial edentulism in the mandible was found to be more common than in maxilla. Middle and senior age groups were most susceptible to tooth loss, with partially edentulous females being more prevalent than males, and caries being the most common cause.
