title: A survey report on effect of root canal fillings and coronal restorations on the periapical status of endodontically treated teeth in a selected group of population.
abstract: OBJECTIVE
  A cross-sectional radiographic orthopantomogram (OPG) survey was done to determine the prevalence of apical periodontitis (AP) in root canal-treated teeth in a selected population, and to evaluate the influence of the coronal restorations (CR) and root canal fillings on the periapical status.
  
  
  METHODS
  A total of 250 OPGs were evaluated out of which root canal treatment (RCT) had been performed in 438 teeth which was taken as the sample size.
  
  
  METHODS
  Chi-square test, odds ratio and p-values were recorded.
  
  
  RESULTS
  The results showed that 53.1% of the endodontically treated teeth presented with AP radiographically. Incidence of AP among teeth with acceptable RCT (32.3%) was significantly lower than those suffering from unacceptable RCT (92.7%). Moreover, adequate CR demonstrated a significantly better periapical status (83.2%) compared to teeth with inadequate CR (37.2%). Also, the combination of adequate CR and adequate root filling resulted in significantly reduced incidence of AP (21.6%) compared to the presence of AP (97%) when both parameters scored as inadequate.
  
  
  CONCLUSIONS
  RESULTS hence demonstrated that a well-performed RCT and well-sealing CR are both essential for the overall success of endodontic treatment. Therefore, a considerable improvement in the quality of RCT and CR in general dental practice is required to promote oral/periapical health.
