Radiographic Assessment of the Prevalence of Pulp Stones in a Yemeni Population Sample

Cone-Beam Computed Tomography-Based Investigation of the Prevalence and Distribution of Pulp Stones and Their Relation to Local and Systemic Factors in the Makkah Population: A Cross-Sectional Study

Objectives This study aimed to assess the prevalence and distribution of dental pulp stones and evaluated their possible associations with local and systemic factors in the Makkah population in Saudi Arabia. Materials and methods Archived cone-beam computed tomography (CBCT) images for 390 patients, from the electronic health records (EHR) in the Dental Teaching Hospital, Umm Al-Qura University, were used. Images were examined in all planes (coronal, sagittal, and axial) for a discrete radiopaque mass in the pulp of all teeth, in both arches. The teeth conditions (the presence of caries, restoration, the periodontal condition, and the presence of pulp stones) were recorded. Additional patient information, including age, gender, and medical condition, was obtained from the patients' archived files. The collected data were statistically analyzed using the Statistical Package for Social Sciences (SPSS) (IBM SPSS Statistics, Armonk, NY) software; a p-value of ≤ 0.05 is considered statistically significant. Results Pulp stone prevalence was 78.97% of the subjects (308 out of 390) and 15.92% of the examined teeth (1644 out of 10326). There were statistically significant differences regarding nationality (p=0.043) and age (p=0.023) but no significant difference between males and females (p=0.876), maxillary and mandibular teeth (p=0.392), and right and left sides (p=0.222) in pulp stone prevalence. Significant differences were found between pulp stone prevalence of sound versus and carious and restored teeth and between periodontally affected teeth and periodontally healthy teeth (p=0.031). Conclusion The prevalence of pulp stones in the Makkah population is high. A positive association was found between nationality, age, tooth restorations, caries, periodontal diseases, and pulp stone prevalence, but no correlation was found with patients' health or gender. The molars were the most affected teeth, while the incisors were the least.

The prevalence of pulp stones in a Turkish paediatric cohort from the Isparta district: an 8-year retrospective radiographic study

PURPOSE

To evaluate the prevalence of pulp stones in a Turkish paediatric cohort from the Isparta district using panoramic radiographs.

METHODS

Panoramic radiographs of 19,857 children and adolescents between the ages of 9 and 18 years were retrospectively analysed to determine the prevalence and distribution of pulp stones. Teeth with pulp stones were classified in terms of dentition, location, dental status and complete or incomplete root formation. Statistical analysis was carried out by applying Chi‑square and Mann-Whitney U. Univariate logistic regression analysis was applied to determine the factors affecting pulp stone status. Differences were considered as significant when p < 0.05.

RESULTS

Out of a total of 19,857 patients, pulp stones were identified in 6.5%. Among the 548,415 teeth examined, 0.96% had pulp stones. The incidence of pulp stones in girls (7.4%) was higher than in boys (5.7%) (p < 0.001). The prevalence of pulp stones increased with age and was significantly higher in molar teeth. A significant difference existed in the incidence of pulp stones according to the jaws (p < 0.001). In both jaws, no statistically significant difference was observed in terms of teeth with pulp stones being on the right and left (p = 0.834). Of molars with pulp stones, 91.8% had completed root formation. The majority of patients (37.7%) had pulp stones in four teeth.

CONCLUSION

Knowing the incidence of pulp stones in paediatric patients by dentists, endodontists, and paediatric dentists will help prevent complications that may occur during applications by facilitating the determination of appropriate methods, especially during endodontic procedures.
