Comparative evaluation of the outcomes of endodontic treatment of abutment teeth under fixed prosthetic constructions in urban and rural patient populations over a 7–8-year follow-up perio

   The aim of this study was to compare the rate of favourable outcomes of endodontic treatment of abutment teeth for fixed prosthetic restorations in urban patients (Grozny) and rural patients (Kurchaloyevsky district, Chechen Republic) over a 7–8-year follow-up period.

   Materials and methods. The urban group comprised 91 patients (mean age 36.7 ± 5.0 years, 187 abutment teeth) and the rural group comprised 79 patients (mean age 44.6 ± 9.5 years, 176 abutment teeth). Outcomes were assessed using WHO (1995) clinical and radiographic criteria.

   Results. Favourable outcomes were recorded in 91.5 % of urban teeth vs 62.5 % of rural teeth (χ² = 44.0; p < 0.001; RR = 1.47; 95 % CI: 1.29–1.66). At patient level, ≥2 unfavourable teeth were observed in 3.3 % of urban vs 25.3 % of rural patients.

   Conclusion. The findings confirm significant disparities in endodontic treatment efficacy related to differences in healthcare accessibility and technological resources.
