Prevalence of apical periodontitis and frequency of root‐filled teeth in an adult Spanish population

Abstract

The prevalence of AP in root-filled and untreated teeth, and the frequency of root-filled teeth were comparable to those reported in previous similar studies carried out in European countries. The prevalence of root-filled teeth with AP was found to be higher compared to that demonstrated in other epidemiological studies.

Epidemiological evaluation of apical periodontitis prevalence in an urban Brazilian population

“…Previous surveys that have reported similar results explained this gender discrepancy as occurring because women have a greater interest in receiving dental care. 19,20 The present study showed a significant difference in AP between men (37.59%) and women (62.41%) (p < 0.05), which may be explained by the smaller number of males in this sample.…”

“…7,13,19,20,21 The results presented herein revealed that the prevalence of apical periodontitis among teeth with previous endodontic treatment or teeth referred for endodontic treatment was highest in the 40-49 age group, followed by the 30-39 age group. Both the 50-59 and the 60+ age groups contained fewer patients with AP.…”

“…Differences in health care system, age, and methodology are likely to contribute to discrepancies. 19,20 The number of individuals aged 40-49 years was significantly higher than that for the other age groups, with the exception of the 30-39 age group, suggesting that individuals of this age more frequently seek dental service. The mean age of the population described in the present study (37.1 ± 16.4 years) is similar to that described by Eriksen et al 7 but is lower than those reported by Tsuneishi et al 13 (50.8 years of age) and Georgopoulou et al 20 (48.0 years of age).…”

“…4,6,21,22,24,25 Certain studies have described a higher prevalence of apical periodontitis (60%-67.5%). 19,20 According to Khabbaz et al, 26 poorer dental health and inappropriate techniques may contribute to this higher prevalence.…”

“…This finding is supported by several epidemiological studies. 4,6,7,11,19,20,22,24,26,27,28,29,30,31 Ng et al 32 demonstrated the need to improve the technical quality of root fillings performed by undergraduate students, especially in molars. The technical quality of the root canal treatment and coronal restoration has a significant impact on the periapical health of root-filled teeth.…”
