Incidence and distribution of pulp stones among Southern Saudi Arabian sub-population.

Purpose: To assess the incidence of pulp stones in molar and premolar teeth of Southern Saudi Arabian adult sub-population.

Materials And Methods: Six hundred patient files were randomly selected from the database (records) of the College of Dentistry outpatient department screened by Oral Medicine and Radiology division. Orthopantomogram and bitewing radiographs using radiovisiographs of first and second maxillary and mandibular molars and premolars were interpreted by three examiners. Pulp stones were identified as definite radiopaque masses and scored as present or absent. Data were subjected to statistical analysis using SPSS version 19.

Results: Out of total 600 patients, pulp stones were found in 88 (14.7%) patients. Females showed statistically significant higher presence of pulp stones in mandibular molars than males. The patients belonging to middle age group (31-40 years) showed statistically significant higher presence of pulp stones than the other two groups in all first and second molar teeth in both arches. The presence of pulp stones was observed to be higher in maxillary arch than mandibular arch with left side having more frequency than the right side of the arch.

Conclusion: The prevalence of pulp stones in the study population was found to be 14.7%, and it was higher in molars than premolars. It is quite significant to know the frequency distribution of pulp stones especially for an endodontist or a dentist to plan the root canal treatment of such teeth accordingly.
