TYPE OF PARTIALLY EDENTULOUS MANDIBULAR ARCHES SEEN AMONG PATIENTS AT THE DENTAL CLINICS OF RAK COLLEGE OF DENTAL SCIENCES

Abstract

 The objective of this study was to establish a relationship between the frequency of tooth loss and partial edentulism (according to Kennedy’s classifications) among different age groups for both gen­ders seen at RAK College of Dental Sciences (RAKCODS). In this cross sectional retrospective study 200 patients were selected randomly and were used to collect the data. The study was conducted from February 2016 to May 2016. The selected participants were divided into different age groups. Frequency of missing teeth was noted between different age groups and the frequency of various Ken­nedy’s classifications and modifications were also noted. Out of 200 patients, 136 were males and 64 were females with age ranging from 18 to 51+ years. Kennedy’s class 3 was the most occurring class (45.5%). In the age group of 21-30 years Kennedy class 3 was noted 17% and Kennedy class 4 was 8%. In the age group of 31-40 years occurrence of Kennedy class 2 was 12%. Kennedy class 1 had the highest occurrence in the age group of 51+ years for both genders. Kennedy class 3 was common in 58 male patients out of 136 and in 33 female patients out of 64. A significant association between age and the occurrence of the different Kennedy’s classifications was observed (p = 0.004). No association with gender was observed in the occurrence of the different Kennedy’s classifications (p = 0.298). 147 patients (73.5%) had partially dentate arches with no modifications. 53 patients (26.5%) were seen with Kennedy class with 1st modification. No association with gender was observed in the occurrence of modification 1, 2 and 3 (p = 0.358).

It was concluded that the highest percentage of tooth loss was among patients aged between 31-40 years, and Kennedy’s Class 3 was the most frequently seen tooth loss.
