  Abstract 


Aim and Objectives:In West Bank, Palestine, there are no studies that have investigated the prevalence of different Kennedy's classifications and their relationship with age, gender, and location of the edentulous arches.
Materials and Methods: This study group consists of 716 patients (463 males and 253 females). The patients were clinically examined to determine the Kennedy classification in Department of Prosthodontics, College of Dentistry, Arab American University.
Results: A total of 716 participants were enrolled in this study; males (62) exhibited higher tooth loss than females (37). Among the Kennedy's classification, Class III was found to be most common in the maxilla (41%) and Class I in the mandible (39%). The least common class was Class IV in both arches.
Conclusions: Kennedy's Class III partial edentulous type was most commonly found in the maxilla and Class I in the mandible.

Keywords: Age, edentulous arches, gender, oral hygiene, partially edentulous jaw, tooth loss

  Introduction Top


Teeth are considered the main component of the oral cavity. Several studies have investigated and reported that the risk of vascular diseases and peripheral arterial diseases increases by tooth loss. Dental caries, periodontal diseases, education level, advanced age, trauma, and smoking are considered the important causes of tooth loss.[1],[2] Various literatures have shown that tooth loss is more common in the maxilla than in the mandible.[3],[4],[5] Kennedy's classification is widely studied and clinically accepted by the dental community. As per the Kennedy's classification, there are four main types of partially edentulous arches such as Class I, Class II, Class III, and Class IV. The Kennedy's classification is widely accepted due to its advantages of immediate visualization and recognition of prosthetic support.[6] The aim of this study was to investigate the prevalence of different Kennedy's classifications and their relationship with age, gender, and location of the edentulous arches in Palestine.


  Materials and Methods Top


This study group consists of 716 patients (463 males and 253 females). The patients were clinically examined to determine the Kennedy's classification in the Department of Prosthodontics, College of Dentistry, Arab American University. A record chart was used to identify age, gender, and location of edentulous arches and Kennedy's classification type. Only partially edentulous patients who had attended the prosthetic dental clinic between the years 2009 and 2015 were included in the study. The survey was based on intraoral examination and digital images of each arch. A computer software Statistical Package for the Social Sciences version 17.0 (SPSS Inc., Chicago, Ill., USA). was used to calculate the overall prevalence of Kennedy's classification, frequency, and percentage.


  Results Top


Out of the 716 partially edentulous patients, 463 were males and 253 were females, with age range from 20 to 70 years. The mean age of the patients was 45 years. Males (62%) exhibited higher tooth loss than females (37%) [Table 1] and [Table 2]. Among the Kennedy's classification, Class III was found to be most common in the maxilla (41%) [Table 3] and Class I in the mandible (39.3%) [Table 4]. The least common class was Class IV in both arches.

  Discussion Top


This is the first study conducted in Palestine which has reported the prevalence of different Kennedy's classifications in partially edentulous patients at the Department of Conservative Dentistry and Prosthodontics, College of Dentistry, Arab American University. According to the present study, there were significant gender differences in partially edentulous patients (35% females and 64% males). This may be because females take more care of their oral health than males and in rural areas, females are not concerned about their oral hygiene. In our study, most of the patients came from rural areas. Our study results are similar to those of various studies, which shows higher edentulousness in males as compared to females.[7],[8] In contrast, many studies have reported that females have higher proportion of edentulousness than males.[9],[10] Our study represents that the frequency of maxillary edentulism (53.5%) is higher than that of mandibular edentulism (46.5%). This is in agreement with various studies.[5],[11] In this study, in the maxilla, the frequency of Class III pattern was most common (41%) and the least common pattern was Class IV (14.9%) and Class II (15.8%). Kennedy's Class I was found to be the most common pattern in the mandible (39.3%) followed by Class III (22%) and Class IV (21.4%) and the least one was Class II.

The study concluded that Kennedy's Class III partial edentulous type was most commonly found in the maxilla and Class I in the mandible.
