“…Tonsilloliths were detected in 300 (13.4 %) and 914 (40.7 %) of the 2244 individuals on panoramic radiographs and CT, respectively in the Takahashi et al study (15). In the present study on CBCT images, the prevalence of palatine tonsil calcifications was 20.4 %, which was higher than that reported by Aspestrand and Kolbenstvedt (16%) and lower than Fauroux et al (24.6%) on CT scans (16,17).…”

“…Comparing the number of calcifications detected, the present study showed that enhanced digital panoramic radiographs allowed for an increase in the detection of soft tissue calcification in 60.18%. This prevalence may have been different than those of other studies (Sutter et al, ; Takahashi et al, ) that assessed limited types of calcification and used non‐enhanced digital images or conventional radiographs. The present authors stated that the possibility of adjusting the image at different levels of brightness and contrast allows for the visualization of calcifications at different stages of mineralization; probably for this reason, a higher number of calcifications were detected when the images were enhanced.…”

“…Comparing the number of calcifications detected, the present study showed that enhanced digital panoramic radiographs allowed for an increase in the detection of soft tissue calcification in 60.18%. This prevalence may have been different than those of other studies (Sutter et al, 2018;Takahashi et al, 2017) prevalence by creating false-positive. We consider that adjustments did not create a soft tissue calcification, because the examiners considered the format, aspect, and localization to classify a high-density area as soft tissue calcification and not only the density.…”

“…Soft tissue calcifications are common in the maxillofacial region, with a detection rate in panoramic radiography of about 19%–19.7% (Ribeiro et al, ; Sutter et al, ). Among the main calcifications visualized on the images, calcified atheroma, calcified lymph, tonsilloliths, antroliths, rhinoliths, sialoliths, phleboliths, and stylohyoid ligament calcification are most frequently observed (Garay, Netto, & Olate, ; Takahashi et al, ).…”

Objective To assess the influence of subjective enhancement of brightness and contrast of digital panoramic radiographs on the detection of soft tissue calcifications. Materials and Methods In this observational study, 500 digital panoramic radiographs were evaluated by two examiners in consensus, who scored the images for the presence of calcifications for each right and left side of the image. After 30 days, all images were revaluated under subjective manipulation of digital brightness and contrast. Calcifications were classified based on the diagnostic hypothesis: sialolith, tonsillolith, calcified atheroma, phlebolith, rhinolith, maxillary sinus antrolith, synovial chondromatosis, lymph node calcification, stylohyoid ligament, triticeous cartilage, or/and upper horn of thyroid cartilage calcification. For intra‐examiner agreement, 20% of the sample was reevaluated. The Kappa test and McNemar test were used (α = 0.05). Results In original images, calcifications were observed in 44.2% of the patients, and in enhanced images, this number was 70.8%. Many calcifications were detected only in enhanced images, mainly in the diagnostic hypotheses of calcified atheroma and stylohyoid ligament. Intra‐examiner agreement was excellent for the detection of soft tissue calcifications (0.82) and for the classification (0.81). Conclusion Subjective enhancement of brightness and contrast alters the detection of soft tissue calcifications in digital panoramic radiograph.

“…Smallsized tonsilloliths are usually asymptomatic, but large ones may present several symptoms such as irritation, pain, discomfort and foreign body sensation, swallowing and eating difficulties, bad breath, bad taste, ear pain, and ulceration [1,2]. Palatine tonsilloliths may cause orofacial pain and glossopharyngeal neuralgia [3]. They may be single or multiple and unilateral or bilateral [4].…”

Significance of the Study• The aim of this study was to compare cone-beam computed tomography (CBCT) and panoramic radiography (PR) for the detection of tonsilloliths. • The detection rate of tonsilloliths was 33.2% on CBCT. • Only 51.4% of the tonsilloliths detected on CBCT were identified by PR. • PR was not adequate to detect tonsilloliths 1 mm or smaller in size. AbstractObjective: A tonsillolith is a concretion of the tonsillar crypt. The aim of this retrospective study was to compare panoramic radiography (PR) and cone-beam computed tomography (CBCT) for the detection of tonsilloliths. Materials and Methods: The CBCT images of 527 patients with maxillofacial volume were evaluated retrospectively. Of these, 175 patients (81 females, 94 males; mean age 51.05 years) had unilateral or bilateral tonsilloliths. In total, 151 of them (67 females, 84 males; mean age, 51.03 years) had PR images performed in the same period and were included in the study. The PR images were examined to ascertain whether known tonsilloliths (from CBCT images) could be detected. The location (unilateral; left or right and bilateral), size, and number of the tonsilloliths were examined on both CBCT and PR images. Descriptive analysis, Spearman's rho correlation coefficient, and χ 2 tests were used for the statistical analysis. Results: The detection rate of tonsillolith was 33.2% on CBCT images. Only 51.4% of the tonsilloliths detected on CBCT were evaluated by PR; the correlation between CBCT and PR was found to be significant (Spearman's r = 0.399, p = 0.000). PR was not adequate to detect tonsilloliths 1 mm or smaller in size. All the calcifications larger than 5 mm were detected on PR images. Conclusion: The results of this study showed that more than half of the tonsilloliths observed in CBCT were also detected in PR. Tonsilloliths larger than 2 mm were more likely to be detected on PR images.
