Objectives: This study compares reduction of strong metal artifacts from large dental implants/bridges using spectral detector CT-derived virtual monoenergetic images (VMI), metal artifact reduction algorithms/reconstructions (MAR), and a combination of both methods (VMI) to conventional CT images (CI).

Methods: Forty-one spectral detector CT (SDCT) datasets of patients that obtained additional MAR reconstructions due to strongest artifacts from large oral implants were included. CI, VMI, MAR, and VMI ranging from 70 to 200 keV (10 keV increment) were reconstructed. Read More

Malignant tumors of the salivary gland are rare, clinically diverse group of neoplasms, among which mucoepidermoid carcinomas (MECs) are reported to be most frequently occurring epithelial carcinomas. MEC at times misleads the clinician because of its atypical location and innocent appearance. Here, we report a case of low-grade MEC in a 70-year-old female patient in the floor of the mouth mimicking as ranula clinically. Read More

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

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

The biological process of epithelial-to-mesenchymal transition (EMT) has been studied in oral squamous cell carcinoma (OSCC) metastasis, but it is rarely evaluated at several stages of oral carcinogenesis. This study aimed to analyze the presence of SNAIL and E-cadherin proteins, markers of EMT, in the development and progression of OSCC, evaluating excised specimens of potentially malignant lesions (oral leukoplakia with and without dysplasia-OL and OLD, respectively), tumor tissues (OSCC), metastatic lymph nodes (LN), and normal oral mucosa (NOM) by immunohistochemistry, considering subcellular localization. Additionally, SNAIL and E-cadherin transcripts were evaluated in vitro by qPCR, using SCC-9 cell line in comparison to human keratinocytes (HPEC). Read More

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

Facial artery perforator flaps have been recently reported by different authors for perioral, nasal alar and cheek defects, but not for intraoral reconstruction. We have extended the use of the facial artery perforator flap in a 56-year-old man with a squamous cell carcinoma of left mouth floor, who was submitted to tumor resection with marginal mandibulectomy and left supraomohyoid neck dissection. The flap was designed according to the size of the defect (5 × 3 cm), centered on the perforator to create a symmetric flap and was tunnelled intraorally by means of a 90° rotation. Read More

Background: Defects following resection of tumors in the head and neck region are complex; more detailed and defect-specific reconstruction would likely result in better functional and cosmetic outcomes. The objectives of our study were: 1) to improve the understanding of the two- and three-dimensional nature of oral cavity and oropharyngeal defects following oncological resection and 2) to assess the geometric dimensions and the shapes of fasciocutaneous free flaps and locoregional tissue flaps required for reconstruction of these defects.

Methods: This study was an anatomic cadaveric study which involved creating defects in the oral cavity and oropharynx in two cadaveric specimens. Read More

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.
