Prevalence of Kennedy Classification in Partially Edentulous Patients - A Retrospective Study

Abstract

The aim of the study is to evaluate the prevalence of partial edentulism according to Kennedy's classification in the South Indian population. A retrospective study was done in which 1419 removable partial dentures were fabricated from 1 June 2019 till 1 March 2020 were included. Data was reviewed from the patients records and analysed the data of 86,000 patients between June 2019 and March 2020 that were documented in a private institution. The data was analyzed using descriptive statistics and Chi square test and pearson correlation was done for checking correlation between age, gender and type of classification. Out of 1419 removable partial dentures, 58.4% were fabricated for males. Class III had the highest prevalence overall and in males and females. There was no significant relation between the type of Kennedy classification of partially edentulous patients with age and gender. Prevalence of Kennedy's Class III was the most common in the South Indian population. The prevalence was more in patients above 50 years of age. Male had more prevalence than females. Gender and age did not affect the prevalence of types of Kennedy's classes.

“…The most common form of edentulism in both maxillary and mandibular arches is Kennedy's Class III, and similar findings were found in studies done by Madhankumar et al, 3 Vadavadagi et al, 4 Shah et al, 6 Gopal et al, 9 Araby et al, 14 Future research in this field should focus on the socioeconomic status of the study group, the availability of oral health care services in their area, quality of life changes before and after tooth extraction and replacement, and patients' willingness to preserve their teeth.…”

“…The Kennedy's Class III pattern of partial edentulism predominates in the current study group, which could be related to patients' willingness to extraction of carious and periodontally affected tooth rather than definitive treatment to preserve tooth. The other most common causes of Class III dominance are failure of root canal treatment, which encourages patients to extraction, and the first molar, which is the first permanent tooth to erupt into the oral cavity, with a higher caries rate and a higher probability of extraction10 .The second most common edentulism in class II in both maxillary and mandibular arches with a value of 38 and 45, respectively, which is in agreement with studies conducted by Vadavadagi et al,4 Shah et al,6 Gopal et al,9 Araby et al,14 but in the study conducted by Madhankumar et al3 the second most common is Kennedy's Class IV in both arches. In our study, Kennedy's Class IV is the least common in the Maxillary arch with 14 people in the study population present with it, but in the Mandibular arch it corresponds with Kennedy's class I with a value of 18.…”
