Atypical MRI and Histopathological Findings in Dermoid Cyst.

Bull Tokyo Dent Coll 2018 ;59(3):207-212

Department of Oral and Maxillofacial Radiology, Tokyo Dental College.

On images, a dermoid cyst is often described as resembling a "sack of marbles" or "marbles in a bag". Typically, it comprises an inhomogeneity filled with multiple nodules in a fluid matrix on both computed tomography and magnetic resonance imaging (MRI). How it appears, however, will vary depending on its histological contents, which may cause confusion in arriving at a diagnosis. Read More

Sublingual gland excision for the surgical management of plunging ranula.

Am J Otolaryngol 2018 Sep - Oct;39(5):497-500. Epub 2018 May 26.

Department of Otolaryngology, Massachusetts Eye and Ear, Boston, MA 02114, United States; Division of Head and Neck Surgery, Massachusetts Eye and Ear, Boston, MA, 02114, United States. Electronic address:

Objective: A plunging ranula is a pseudocystic collection of mucin extravasated from the sublingual gland into the floor of mouth and through the mylohyoid muscle into the neck. While the lining of a ranula is non-secreting and resection of the sublingual gland is adequate for simple sublingual mucoceles, many surgeons attempt to address plunging ranulas with extensive transoral and transcervical dissections. We review our experience managing plunging ranulas with intraoral sublingual gland excision and ranula drainage alone. Read More

Giant Epidermoid Cyst of the Maxillary Sinus: A Postoperative Complication?

J Craniofac Surg 2018 Sep;29(6):e607-e608

Department of Otorhinolaryngology, Near East University, Faculty of Medicine, Nicosia, Cyprus.

Epidermoid cysts are benign lesions, which are usually detected on the floor of the mouth in the head and neck region. They can develop from abnormal epithelial components of an ectoderm tissue during the embryological life or alternatively they can arise from the implanted epithelium after trauma or surgery. The diagnosis of an epidermoid cyst in the maxillary sinus can be challenging and it could be easily mistaken for any benign or malign lesion of the nasal cavity and paranasal sinuses. Read More

Oral Health Disparities Across the Life Span.

Dent Clin North Am 2018 04;62(2):177-193

UNC School of Dentistry, The University of North Carolina at Chapel Hill, Koury Oral Health Sciences Building, Room 4508, Chapel Hill, North Carolina 27599-7450.

Despite improvements in the oral health status of the US population as a whole, a disproportionately higher burden of oral diseases and disorders are borne by those individuals from low-income and racial and ethnic minority groups. These differences in health status, health outcomes, or health care use between distinct socially disadvantaged and advantaged groups are well documented and known as health disparities. It is vital that members of the dental profession understand the distribution of oral health and disease across different populations and the life span and participate in developing innovative and sustainable approaches to eliminate oral health disparities.
