Abstract
Aim: This study aimed to evaluate the prevalence of partial edentulism among patients of Faculty
of Dentistry Cairo University.
Methodology: This cross-sectional study included 362 partially edentulous patients aged from 18
to 80 years old, Data were collected using a recording sheet (a self-designed proforma). Visual
examination was then done by seating the patient on the dental chair and using the dental mirror for
determining the prevalence of Kennedy’s classification and determination of which class.
Results: Total number of females were 220 and males were 142. Five patients were within the age
range of (18-30), fifty patients were within age range (31-40), ninety-four patients were within age
range (41-50), one hundred and ten patients were within age range (51-60), eighty-five patients
were within age range (61-70) and eighteen patients were within age range (71-80). The total
number of urban subjects was 239 and rural subjects were 123. Patients having partial edentulism
in the maxillary arches were 172, while in the mandibular arches were 256, thus indicating a higher
incidence in the mandibular arch than in the maxillary arch. Total classes included 145 (33.9%) CI,
149 (34.8%) CII, 105 (24.5%) CIII and 29 (6.8%) CIV. 229 patients lost their teeth due to caries,
55 patients due to PDL disease, six patients due to trauma, 70 patients due to both caries and
periodontal disease, 1 patient due to trauma and PDL disease, while 1 patient due to other reasons.
Conclusion: Kennedy’s Class II was the most common in both dental arches. Neither
gender nor age had any significant effect on the prevalence of various Kennedy’s classes.
Mandibular partial edentulism was found to be more common than maxillary partial edentulism.
Caries was the most common cause of teeth loss.
