Introduction:

Partial edentulism is a final condition to the presence of dental caries related to various social, demographic and cultural factors. Currently, there are few studies that assess the state of partial edentulism and its association with the socioeconomic cultural level.

Objective:

To determine the frequency of the type of bimaxillary partial edentulism according to Kennedy´s Class and its possible association with the socioeconomic cultural level in patients treated in the clinic of the Faculty of Dentistry of the National University of San Marcos in 2016.

Material and methods:

A descriptive, observational and cross-sectional study was conducted. The sample consisted of 100 randomly selected partial edentulous adult patients who were evaluated by means of a survey and an oral clinical examination. The survey was made up of the data that relate socioeconomic cultural level. The clinical examination was evaluated with an odontogram to determine the type of edentulism according to Kennedy´s classification.

Results:

The most frequent type of partial edentulism was Kennedy's Class III in the maxillary arch (50%) and in the mandible (49%), which was mainly present in patients that belonged to the average socioeconomic cultural level (83%). There was no statistically significant association between the socioeconomic cultural level and the type of partial edentulism according to Kennedy´s Class in both dental arches.

Conclusions:

In the studied population, there is a greater frequency of partial bimaxilar edentulism according to Kennedy's Class III and a preponderance of the socioeconomic cultural level. However, there is no association between the type of partial edentulism according to Kennedy´s Class and the socioeconomic cultural level.
