Knowledge, Attitude, and Practice of Dutch Dentists on Oral Leukoplakia and Their Possible Role in Its Follow-Up.

Objective: To assess the knowledge, attitude, and practice of Dutch dentists on oral leukoplakia (OL) and to what extent these aspects are related to whether or not dentists regularly monitor patients with OL.

Material And Methods: A self-developed questionnaire was distributed via a web survey among a sample of dentists participating in an intervision program. Of 1626 invited dentists, 437 (26.

Nasal Septal Abscess Caused by Protrusion of a Dental Implant Into the Nasopalatine Duct: A Case Report.

Objective: A nasal septal abscess after placement of a dental implant is seldom seen and is usually caused by an infection around the implant. A septal haematoma following dental implantation leading to septal abscess formation has never been reported.

Methods And Results: We present a case of a patient who developed a septal abscess after dental implantation without accompanying signs of infection around the implant.

Motor vehicle accidents-related maxillofacial injuries: a multicentre and prospective study.

Objectives: The purpose of this European multicenter prospective study was to obtain more precise information about the demographic characteristics and etiologic/epidemiologic patterns of motor vehicle accidents (MVA)-related maxillofacial fractures.

Study Design: Of the 3260 patients with maxillofacial fractures admitted within the study period, 326 traumas were caused by MVAs with a male/female ratio of 2.2:1.

Global incidence and profile of ameloblastoma: A systematic review and meta-analysis.

Objectives: To evaluate the global incidence of ameloblastoma and to provide a profile of ameloblastoma patients.

Material And Methods: A systematic review and meta-analysis was conducted. Searches were performed in PubMed, EMBASE, SCOPUS, and Web of Science for articles published from 1969 to 2018 for the global incidence and from 1995 to 2018 for the profile of ameloblastoma patients.

Global incidence of oral and oropharynx cancer in patients younger than 45 years versus older patients: A systematic review.

Head and neck squamous cell carcinoma (HNSCC) is typically regarded as a disease of elderly people. However, increasing numbers of patients worldwide with HNSCC at younger age (defined as <45 years old) have been reported in recent years. To assess geographical variations and trends worldwide in incidence of oral and oropharyngeal cancer in young patients, a systematic review was conducted in PubMed and Google scholar databases from 1975 to June 2016.

Complications of Sialendoscopy in Patients With Sjögren Syndrome.

Purpose: Recent literature suggests that sialendoscopy of the major salivary glands could alleviate symptoms of Sjögren syndrome (SS) and restore salivary function. The aim of this study was to evaluate the authors' experience of sialendoscopy of the salivary glands in patients with SS.

Materials And Methods: In this retrospective case series study, the surgical data of patients with SS who had undergone sialendoscopy at the VU University Medical Center (Amsterdam, The Netherlands) from November 2014 through April 2015 were used.

Fracture of the genial tubercles of the mandible: case report and review of the literature.

Fracture of the genial tubercles is a rare occurrence and can occur as a solitary fracture or an associated fracture of the mandible. A solitary fracture seems to be associated with severe atrophy of the mandible. A report of a case of fractured genial tubercles in an 80-year-old edentulous female patient is described and a review of the literature is presented.

[A woman with a pigmentation of the hard palate].

A bluish flat pigmented lesion of the hard palate of a 51-year-old woman was excised to exclude malignancy, in particular oral malignant melanoma. On histopathological examination, depositions of black pigment were seen accompanied by several foreign body giant cells. Probably due to a childhood trauma, a pencil point had penetrated the hard palate.

[Sialendoscopy for obstructive disorders of the salivary glands].

Obstructive disorders of the salivary glands usually manifest as a swelling which is associated with meals ('mealtime syndrome') as well as inflammation of the gland. Obstruction of the salivary ducts of the parotid and submandibular glands is usually caused by a salivary stone, mucous plug or by a stenosis. Until recently, the options for diagnosis and treating these conditions were limited.

Traumatic lingual ulceration in a newborn: Riga-Fede disease.

Riga Fede disease is a reactive mucosal disease as a result of repetitive trauma of the tongue by the anterior primary teeth during forward and backward movement. Although the aspect of the lesion might be impressive, its nature is relatively benign. The history and clinical features are most often so typical that there is seldom a need for addititonal histopathological examination.

18F-FDG PET as a routine posttreatment surveillance tool in oral and oropharyngeal squamous cell carcinoma: a prospective study.

Unlabelled: The purpose of this study was to evaluate the role and timing of serial (18)F-FDG PET scans as routine surveillance for detecting early locoregional recurrence, distant metastases, and second primary tumors in patients treated for advanced squamous cell carcinoma (SCC) in the oral cavity or oropharynx during the first year after completion of their curative treatment.

Methods: Forty-eight consecutive patients with SCC in the oral cavity or oropharynx were included after completing their initial therapy with curative intent. Prospective follow-up of the participants was 2-fold: regular follow-up (history and physical examination) and serial (18)F-FDG PET scans.

Primary malignant melanoma of the vermilion of the lip.

Malignant melanoma of the vermilion of the lip is a rare entity, and because of the common occurrence of other benign pigmented lesions, it is easily overlooked. Early diagnosis is of the utmost importance, in the first instance to minimise the risk of haematogenous, lymphatic, perineural and trans- (salivary) ductal spread. The second reason for early diagnosis is that surgery is the only effective form of treatment.

Frozen section examination of the margins for resection of squamous cell carcinoma of the lower lip.

Objectives: Our goal was to evaluate the role of frozen section margin examination in the surgical management of squamous cell carcinoma of the lower lip.

Materials And Methods: We reviewed frozen section examination of the resection surfaces of 131 consecutive patients surgically treated for squamous cell carcinoma of the lower lip during the period January 1980 to January 1999. When invasive carcinoma or carcinoma in situ was present at the resection surface, the margin was defined as positive and re-resection was performed.

Ectomesenchymal chondromyxoid tumor of the anterior tongue. Report of two cases.

The ectomesenchymal chondromyxoid tumor (ECT) of the tongue is a recently proposed entity that presents clinically as a slow-growing, painless, firm, submucosal nodule of the anterior dorsum of the tongue. The lesion is histologically characterized by a well-circumscribed lobular proliferation of ovoid and round cells growing in net-like sheets in a chondromyxoid background; there may be scattered multilobulated nuclei and occasional foci of atypia. The tumor is characterized immunophenotypically by a mesenchymal and neurogenic profile with positivity for vimentin, S-100, and GFAP.

Supraomohyoid neck dissection in the management of cervical lymph node metastases of squamous cell carcinoma of the lower lip.

Background: Supraomohyoid neck dissection (SOHND) is generally considered an adequate staging procedure in selected patients with squamous cell carcinoma (SCC) of the lip and oral cavity, with clinically negative nodes in the neck that are at increased risk for occult metastatic disease. The potential role of SOHND as a therapeutic surgical procedure for cervical metastasis limited to level I is controversial.

Methods: A series of 44 patients with clinical cervical lymph node metastases at level I from SCC of the lower lip is reported to evaluate the results of a treatment protocol consisting of therapeutic SOHND on indication followed by radiotherapy.
