The maxillofacial region is composed of various anatomical structures that are observed as different densities on radiographs. In addition to teeth, bones and soft tissues, variations and pathological conditions also contribute to this density range. Radiographic interpretation may challenge practitioners to determine an exact diagnosis. It is difficult to diagnose calcifications caused by pathological conditions, especially areas that neighbour teeth and bone. 1,2 Idiopathic and dystrophic calcifications are seen in maxillofacial soft tissues. Dystrophic calcifications are the most common type. 3,4 Calcifications visualised on dental images are tonsilloliths, sialoliths, phleboliths, artery calcifications, adenoliths and lymph node calcifications. Tonsilloliths are composed of calcium and magnesium salts; the exact pathogenesis is not defined. 5 They are sometimes in concordance with clinical symptoms but may be asymptomatic. 6 Sialoliths are idiopathic calcifications in salivary glands. The submandibular gland is a favoured location because of its mucous secretions, narrowed orifice and opposite flow to gravity. 7 Phleboliths in the head and neck region can be observed in all age groups. Vascular malformation areas and thrombosis provide bases for their formation, with deposition of calcium phosphate and carbonate. In extreme examples, they may cause aesthetic problems, disrupt blood flow and lead to harmful inflammation, although they are generally

“…Calcifications in maxillofacial region such as tonsilloliths may be incidental findings in X-ray panoramic radiographs in daily practice, whenever there is an indi-cation [18]. Previous studies reported that the detection of palatine tonsilloliths varies, and the prevalence in CT is 16.0-46.6% and in panoramic radiographs -7.3-13.4% only [7]. Two-dimensional image, superimposition of structures, distortion, and magnification may be diagnostic challenges in interpretation of panoramic radiographs [2,9,13,19].…”

“…They may be asymptomatic or cause dysphagia, globus sensation, halitosis, otalgia, peritonsil-lar abscess, swelling in the tonsillar fossa, glossopharyngeal neuralgia, orofacial pain, upper airway obstruction, and sleep breathing disorders. They may be incidentally found in three-and two-dimensional radiological examinations [1][2][3][4][5][6][7][8][9][10][11][12][13]. TLs appear as small opacities, overlapping the middle portion of mandible ramus, or as multiple poorly defined radio-opacities, which may be oval, round, or irregular in shape, superimposed on the soft tissues' shadows.…”

Introduction: Calcifications found in the crypts of palatal tonsils, called tonsilloliths, are considered an incidental finding in panoramic radiographs. Dentists and radiologists should be aware of their radiological appearances in order to avoid diagnosis of different calcifications. Objectives: The objective of the research was to examine the prevalence and characteristics of tonsillar calcifications visible in panoramic radiographs in a sample of Polish population. Material and methods: The study included one thousand consecutive digital dental panoramic radiographs taken with Planmeca Prostyle X-ray machine in 577 females and 423 males aged from 5 to 88 years. The presence of tonsilloliths, their characteristics (single or multiple) as well as localization according to 6 regions (1-3 shadows cast on the mandibular ramus above, at and below the level of soft palate, 4-below mandible, 5-below and posterior to mandibular angle, 6-posterior to mandibular ramus) were assessed. Results: Tonsilloliths were detected in over 24% of panoramics. Prevalence in females and males was comparable. Findings were more prevalent in the following age groups: 30-39 years, 50-59 years (37.5%), and 40-49 years (35%). They were far less frequent in patients below 30 years of age. Tonsillar calcifications were found in 511 regions in 242 patients, and in 116 cases they were single. Almost 30% of calcifications were detected in region 2 and 25% in region 3. Over 65% of tonsilloliths were found bilaterally. Conclusions: Tonsilloliths are frequent incidental finding in X-rays. About one-quarter of analyzed panoramics revealed the presence of stones.

Background The treatment of CT remains controversial. The aim of this study was to retrospectively evaluate the pain and functional outcomes of arthroscopic excision with or without rotator cuff repair for treating calcified tendinitis of the rotator cuff.Methods Between Jan 2015 and Apr 2018, a total of 38 patients with 39 shoulders CT of the rotator cuff underwent arthroscopic surgery and were followed for at least two years. The clinical outcomes were evaluated at intervals of 2, 4, and 8 weeks and 3, 6，12 and 24 months after the surgery and annually thereafter. The efficacy measures included the visual analogue scale (VAS) score, University of California at Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score and radiographic outcomes.Results All patients underwent follow-ups, and the mean follow-up time was 45.38 months. The VAS score significantly decreased from 73.59±11.35 mm before the surgery to 26.41±10.63 mm at 6 months after surgery and continued to decrease to 5.64±5.02 mm at the end of the follow-up period (all p < 0.01). This result was supported by a significant increase in both the UCLA score and ASES score (all p<0.01) after surgery. Plain radiographs after surgery revealed complete calcification removal in all patients. No recurrence was observed during the follow-up period.Conclusions Arthroscopic excision can relieve pain and improve shoulder joint function in patients with CT. Additional randomized controlled studies need to be conducted to confirm our findings.
