Abstract

The purpose of this study was to identify the prevalence of molars with furcation involvements grades II and III in adults participating in the Jönköping Oral Health Study 2003. The second aim was to study correlations between different variables and the presence of furcation involvement in these individuals. The present study was performed using bitewing and apical radiographs from 329 subjects. Furcations were considered healthy if the furcation was filled with bone up to the fornix. Two thousand fourteen molars fulfilled the inclusion criteria. The prevalence of molars with furcation involvements was 8.3%. Univariate analysis showed that plaque, age, and presence of periodontal pockets were significantly correlated with furcation‐involved molar/s (P ˂ 0.0001). Gingivitis and education were also significantly correlated to the presence of furcation involvement (P ˂ 0.006) and (P ≤ 0.01), respectively. Gender had no association with presence of involvements. Multivariate analysis showed that age and presence of periodontal pockets were significantly correlated with furcation involvement (P ˂ 0.0001). Smoking was also found to be associated with furcation involvement (P ˂ 0.04). The tooth most frequently and least likely displaying furcation involvement was the maxillary first molar and the mandibular second molar, respectively. Periodontal pockets, age, and smoking were risk indicators for furcation involvement.

Highlights

The most frequently lost teeth in a population are the first and second molars (Corraini et al 2008)
Larato studied the prevalence of molars with furcation involvement in 305 dry adult skulls
He found that the maxillary first molar was the tooth that most frequently displayed furcation involvement and mandibular second molars were the least frequent

Summary

Introduction

The most frequently lost teeth in a population are the first and second molars (Corraini et al 2008). Furcation involvement is frequently more common in maxillary molars than in mandibular molars (Ross & Thompson 1980, Svardstrom & Wennstrom 1996, Dannewitz et al 2006). A study by Ross and Thompson (1980) found that the prevalence of furcation involvement in maxillary molars was 90%; compared with 35% in mandibular molars. Studies on dry skulls have found that maxillary first and second molars have a higher risk for furcation involvement than mandibular molars. Radiographs have been used to determine the presence or absence of furcation involvements with different results (Rees et al 1971, Deas et al 2006). The agreement on the absence of furcation involvement was 92.2%
