    Purpose: The aims of this study were to determine the prevalence of pulp stones in a group of Turkish dental patients using panoramic radiographs and dental records, and to report any associations between the presence of pulp stones and age, sex, tooth type, dental status, dental anomalies or systemic diseases. Materials and Methods: Data were collected through radiographic examination of panoramic radiographs and dental records of 4798 dental patients. The presence of pulp stones was recorded. Chi-square analyses were used to compare the frequency of occurrence o75f pulp stones between the parameters. Results: Pulp stones were identified in 168 (3.5%) patients examined. Six hundred twenty (0.5%) of 122405 teeth had pulp stones. Gender, tooth type and dental status were correlated with the presence of pulp stones (p< 0.05). No significant association existed between pulp stones and age, dental anomalies or systemic diseases (p>0.05). Conclusion: Under the limitations of the present study, pulp stones were detected in 3.5% of 4798 patients and 0.5% of 122405 teeth examined using panoramic radiographs. Molars contained significantly more pulp stones than other tooth types. Carious and/or restored first and second molars exhibited a significantly higher prevalence of pulp stones than intact molars. Further studies are needed to clarify the higher pulp stone prevalence in molars and the possible association between the occurrence of pulp stones and pulpal irritations.

    A comparison of the use of cone-beam computed tomography and panoramic radiography in the assessment of pre-eruptive intracoronal resorption
    (Taylor & Francis Ltd, 2016) Demirtas, Omer; Dane, Asim; Yildirim, Eren
    Objective: This study aimed to investigate the prevalence of pre-eruptive intracoronal resorption (PIR) using cone beam computed tomography (CBCT) and panoramic radiography and to compare the findings of these imaging techniques.Methods: This retrospective study consisted of 733 patients who had at least one unerupted tooth and had undergoneimaging with both three-dimensional (3D) CBCT and two-dimensional (2D) panoramic radiography. In all the images, the number of teeth with intracoronal resorption, affected tooth type and number, and size and location of the PIR defects were recorded. The McNemar test was used to compare the prevalence of PIR in the CBCT and panoramic images.Results: Fewer PIR defects were detected in the panoramic images (3.1% of the patients) than in the CBCT images (9.5% of the patients) (p<.001). According to the CBCT images, the distribution of PIR defects was as follows: third molars (59.5%), canine teeth (11.4%), second molars and premolars (7.6% for both), supernumerary teeth (5.1%), second molars (3.8%), central incisors (2.5%), and first premolar and primary second molar teeth (1.5% for both). According to the scoring classification system for PIR defects, PIR 1 defects were the most common (65.8%), followed by PIR 3 (24.1%) and PIR 2 (10.1%). Of these defects, 69.6% were located in the central aspect of the crown. Ectopically positioned teeth showing intracoronal resorption accounted for 51.9% of the cases of PIR.Conclusions: CBCT detected more cases of PIR than panoramic radiography. The mandibular third permanent molar was the most commonly affected tooth.
