摘要: Introduction: This cross-sectional survey determined the dental prevalence of apical periodontitis (AP) in selected Iranian population, and evaluated influence quality root canal treatment (RCT) their coronal restorations (CR) on periapical status. Materials Methods: A total 1064 panoramic radiographies were by two observers during 2009. The RCT i.e. length/density fillings CR addition to status endodontically treated teeth recorded. Their interrelationship was analyzed Chi-squared, logistic regression Spearman's rho statistics. Hosmer Lemeshow tests used for assessing fitness model one sample k-s test evaluating normality data. Results: Our results showed that 527 (52%) presented with AP radiographically. percentages which fulfilled criteria an acceptable or radiographically 42.3 62.5 respectively. Incidence among (29.1%) significantly lower than those suffering from unacceptable (68.8%) (P<0.001). Moreover, adequate demonstrated a better (58.6%) compared inadequate (30.3%) incidence ranged 25.6% (good qualities) 79.5% (bad Cases both RCT/CR 11 times more likely have cases RCT/CR. found impact health teeth. Conclusion: There are significant high number technically endodontic restorative treatments Iran; therefore considerable efforts needed improve standards treatments.
