title: Prevalence and analysis of factors related to ooccurrence of pulp stone in adult restorative patients.
abstract: BACKGROUND
  Pulp stone, though of an unclear aetiology, is clinically common. It potentially poses procedural difficulty to the endodontist and may also be a marker of an underlying systemic condition.
  
  
  OBJECTIVE
  The study investigated pulp stone occurrence in adult restorative patients. It also highlighted the relationship between pulp stone and pristine posterior teeth, chronic periodontitis and posterior teeth with abrasion, as well as the effect of age and gender on pulp stone occurrence.
  
  
  METHODS
  Three hundred subjects, aged 18-60 years participated in the cross sectional study. Pristine teeth, teeth with chronic periodontitis and those with abrasion were recruited.
  
  
  RESULTS
  Pulp stone was seen more often in the 41-50 years age band, in molars and in teeth with chronic periodontitis but less often in teeth with abrasion. In addition, coronal and free form of pulp stone were more popular.
  
  
  CONCLUSIONS
  It is recommended that researchers should pay special care in case selections, and during biomechanical coronal instrumentation.
