Effect of voxel size on detection of fenestration, dehiscence and furcation defects using cone-beam computed tomography
ConclusionSmaller voxel size had higher sensitivity and lower specificity for detection of all defects except for grade I furcation defects, for which the smaller voxel size had higher sensitivity and higher specificity. (Source: Oral Radiology)

Osteolipoma: a review of the literature and a rare case report
ConclusionDifferential diagnosis includes a wide range of lesions; therefore, the clinical and radiographic evaluation should be confirmed by histopathological examination. The suggested treatment is complete surgical excision and follow-up, and the prognosis is generally good. (Source: Oral Radiology)

Ultrasound dimensional changes of the anterior belly of the digastric muscle induced by orthognathic surgery and botulinum toxin A injection in Class II malocclusion
ConclusionsPostoperative ultrasound (US) follow-up measurements in patients with Class II malocclusion, orthognathic surgery and intraoperative BTX-A injection in the ABDM, showed dimensional changes of the muscle, with elongation and thinning. The muscular modifications were more pronounced at 6 months postoperatively, indicating consistency and potential benefit of using BTX-A in reducing the risk of surgical relapse. Further data on longer-term follow-up and larger number of cases are necessary. (Source: Oral Radiology)

Nature and clinical significance of incidental findings in maxillofacial cone-beam computed tomography: a systematic review
ConclusionMost IFs in maxillofacial CBCT are either normal variants or findings that do not require referral or treatment. There was no clear consensus on the recommended management of most common IFs. The lack of consensus on clinical significance emphasizes the importance of collaboration between medical and dental specialties to establish professional guidelines for the management of commonly encountered IFs in CBCT.

Shear wave elastography of temporomandibular joint disc and masseter muscle stiffness in healthy children and adolescents: a preliminary study
ConclusionThe stiffness of the TMJ disc was significantly lower in the posterior part than in the anterior or middle parts. The mean stiffness was significantly higher in the open mouth than in the closed mouth position. Neither elasticity nor velocity were associated with age, height, weight, or BMI.

Ultrasound-guided sialo-irrigation for the treatment of chronic sialodochitis with sialolithiasis
AbstractSialolithiasis is one of the most common causes of salivary duct obstruction. In the last 20 years, minimally invasive procedures like sialendoscopy, extracorporeal lithotripsy, and basket snaring are increasingly being used for the treatment of salivary gland duct stones. Sialo-irrigation of the salivary gland is an effective procedure for treating inflammation and providing symptomatic relief. This procedure can be employed for the treatment of sialolithiasis using the back pressure of instilled saline. Sialo-irrigation under ultrasound (US) guidance allows for dynamic studies showing real-time images during di...

Pre-treatment MRI predictor of high-grade malignant parotid gland cancer
ConclusionsMorphological assessment on MRI and texture parameters alone is not sufficient to estimate the grade of parotid cancer. MRI findings of neck lymph node metastases, as well as patient characteristics such as age (older patients) and gender (male) can be suggestive of high-grade parotid gland cancer in pre-treatment evaluation.

Tomographic evaluation of buccal bone in different skeletal patterns and incisors inclination
ConclusionsKnowledge of alveolar bone height and thickness can alter the treatment plan in orthodontics. During orthodontic treatment, more attention should be paid to the lower incisors and vertical teeth because of poor BB conditions, especially in class III skeletal patterns. (Source: Oral Radiology)

Ghost cell odontogenic carcinoma arising in the background of a calcifying odontogenic cyst
This report highlights an additional case of a GCOC arising from a pre-existing COC after 3 years in an adolescent male. The patient initially presented with a painless swelling of the right mandibular corpus. Panoramic radiographic examination showed an expansive unilocular radiolucent lesion. After 3 years, the radiographic features appeared more aggressive with increased expansion an d cortical perforation. A wide surgical resection was performed, whereby the lesion was diagnosed as a GCOC. Due to the rarity of these malignant neoplasms, limited information is available regarding their biological behaviour. One-year...
