RESUMEN
INTRODUCTION: The incidence of human papillomavirus (HPV)-related oropharyngeal cancer is rising, thus the understanding of HPV infection and vaccination among oral healthcare professionals is becoming increasingly important. This study aimed to investigate the knowledge of Dutch dental hygiene students on HPV infection and vaccination and assessed various aspects of HPV-related oropharyngeal cancer. METHODS: This descriptive cross-sectional study invited the entire Dutch dental hygiene student population registered in September 2016 to complete an online questionnaire concerning the knowledge of HPV infection and vaccination, including the aspects of HPV-related Oro-Pharyngeal Squamous Cell Carcinoma (OPSCC). Data were analysed using t-tests, Mann-Whitney U tests and Chi-square tests. RESULTS: Invited were all 1248 Dutch dental hygiene students and 232 (18.6%) students completed the questionnaire. More than 95% of the students indicated HPV infection as a risk factor for OPSCC and 48.7% was aware of the availability of HPV vaccination. Additionally, students considered it important to discuss HPV as a risk factor for oropharyngeal cancer with their patients. In general, the students scored highest on the questions about risk factors for OPSCC and poorest on the questions about general HPV knowledge and HPV vaccination. Although the mean overall knowledge score was significantly higher in senior compared with junior students, knowledge scores of senior students remained insufficient. CONCLUSION: This study identified deficits in knowledge of HPV and HPV vaccination among Dutch dental hygiene students. Future research should focus on improving the content of dental hygiene curricula and development of ongoing educational tools for dental hygienists.

OBJECTIVES: To identify possible associations between patients' demographics and habits and the clinical aspects and histopathological characteristics of oral leukoplakia (OL) at patients' first visit. METHOD: A total of 140 consecutive patients with OL at a single institute between 1997 and 2019. All biopsies were microscopically examined for classic dysplasia (CD) (WHO definition oral epithelial dysplasia) and differentiated dysplasia (DD) known from differentiated vulvar intraepithelial neoplasia. Clinical characteristics were correlated to histopathological diagnosis and odds ratios (OR) were calculated. RESULTS: A total of 96 females and 44 males, mean age 58 years, were presented. OLs were found mainly on the tongue (41%) and floor of mouth (FOM) (18%). Homogeneous OLs (58%) were associated with smoking, FOM and size <2cm and non-homogeneous OLs (42%) with non-smokers. No dysplasia was present in 40% and any dysplasia (AD) in 60%. Tongue OLs were correlated with AD (OR:6.0) and CD (OR:5.7). FOM OLs were correlated with CD (OR:4.5). DD was correlated with non-homogeneous OLs (OR:2.6). CONCLUSIONS: CD was most frequently observed in tongue and FOM OLs, while DD was associated with non-homogeneous OLs. In this series of patients, there was no consistent reliable association between the clinical and histopathological features and clinical characteristics can therefore not substitute microscopic examination of biopsies.

OBJECTIVES: Evaluate whether regular follow-up of oral leukoplakia (OL) resulted in early detection of malignant transformation (MT). METHOD: Two hundred and twenty-two consecutive patients with OL (147 females, 75 males); median follow-up period of 64 months (range: 12-300). Three groups were distinguished: group A (n = 92) follow-up at the hospital; group B (n = 84) follow-up by their dentist; group C (n = 46) lost to follow-up. RESULTS: OLs in group B compared to group A, were smaller in size (<2 cm; p < 0.001), showed more hyperkeratosis (p < 0.001) and less moderate/severe dysplasia (p < 0.001). MT occurred in 45 (20%) patients: 32 (35%) in group A, five (6%) in group B and eight (17%) in group C. There was no significant difference in clinical tumour size between group A (median: 15 mm, range: 1-40) and group B (median: 10 mm, range: 3-25; p = 0.496). Tumour size was smaller for patients in groups A and B (median: 10 mm, range 1-40) compared to group C (median: 33 mm, range: 3-100; p = 0.003). There was a positive correlation between tumour size and interval between the last visit in all patients (p = 0.022). CONCLUSION: Regular follow-up of OL resulted in early detection of MT. If properly selected, follow-up of OL performed by the dentist seems feasible.
RESUMEN
AIM: In Europe, approximately 150.000 patients are diagnosed with head and neck cancer annually. Dentists play an important role in prevention and detection at an early stage when survival rates are best. This study aims to evaluate content of head and neck cancer education curricula of European dental schools. MATERIALS AND METHODS: A questionnaire, comprising 20 questions about content of curricula and teaching methods, was distributed to the deans of all 234 members of the Association for Dental Education in Europe. RESULTS: The response rate was 24%. All dental schools included head and neck cancer screening practices in their curricula, two-thirds had their students perform this screening on all patients routinely and education was mostly divided over various courses (65%). A variation in content of education in screening practices and counselling patients about various risk factors was reported. Alcohol and tobacco use were included in most curricula as risk factors for head and neck cancer (98%), gastro-oesophageal reflux was less frequently included (41%). The human papillomavirus (HPV) as a risk factor for oropharyngeal cancer was included in 94% of curricula and 87% also contained education about strategies to discuss prevention of HPV-related cancer. No association was found between curricula containing strategies about discussing HPV-related cancer and inclusion of the HPV vaccine in national immunisation programmes. CONCLUSION: Head and neck cancer teaching programmes show a considerable variation across European dental schools. Development of a unified teaching programme suitable for all European dental schools seems warranted.

OBJECTIVES: Although bowel symptoms are often predominant, inflammatory bowel disease (IBD) patients can have several oral manifestations. The aim of this study was to investigate the prevalence of dental caries and periodontal disease in patients with Crohn's disease (CD) and ulcerative colitis (UC) compared to an age and gender-matched control group of patients without IBD. MATERIAL AND METHODS: The DMFT (Decayed, Missing, Filled Teeth) scores and the DPSI (Dutch Periodontal Screening Index) of 229 IBD patients were retrieved from the electronic health record patient database axiUm at the Academic Centre for Dentistry Amsterdam (ACTA) and were compared to the DMFT scores and DPSI from age and gender-matched non-IBD patients from the same database. RESULTS: The total DMFT index was significantly higher in the IBD group compared to the control group. When CD and UC were analyzed separately, a statistically significant increased DMFT index was observed in CD patients but not in UC patients. The DPSI did not differ significantly between the IBD and non-IBD groups for each of the sextants. However, in every sextant, IBD patients were more frequently edentulous compared to the control patients. CONCLUSION: CD patients have significantly more dental health problems compared to a control group. Periodontal disease did not differ significantly between IBD and non-IBD groups as determined by the DPSI. CLINICAL RELEVANCE: It is important that IBD patients and physicians are instructed about the correlation between their disease and oral health problems. Strict oral hygiene and preventive dental care such as more frequent checkups should be emphasized by dental clinicians.

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. RESULTS: Seven studies on the incidence rate of ameloblastoma were included in the meta-analysis. These studies only covered Europe, Africa, and Australia. The pooled incidence rate was 0.92 per million person-years (95% CI: 0.57-1.49), with significant heterogeneity between studies. Forty-two articles provided profile data of 6,446 ameloblastoma patients. Mean age was 34 years and the peak age incidence in the third decade of life. In Europe and North America, ameloblastoma mostly occurred at an older age when compared to Africa and South America. A slight male preference (53%) was found, and the mandible appeared to be the preferred site. The most common type of ameloblastoma was multicystic. The histopathologic patterns were mostly follicular and plexiform. CONCLUSIONS: This is the first study assessing the global incidence of ameloblastoma. The pooled incidence rate was determined to be 0.92 per million person-years.

Objectives The aim of this retrospective study was to determine whether there is a difference in oral health between recreational ecstasy users and non-recreational drug users.Study design In a cross-sectional study, dental records of 149 individuals visiting an academic dental clinic in Amsterdam who reported recreational ecstasy use, defined as no more than twice a week, were systematically analysed and compared to a group of age- and sex-matched non-drug users randomly selected from this institute. The parameters retrieved from the dental records were decayed, missed and filled teeth index (DMFT), number of endodontically treated teeth, presence of active caries lesions, periodontitis, tooth wear, xerostomia and self-reported use of oral hygiene devices.Results Periodontitis, active caries lesions and xerostomia were statistically significantly more present in ecstasy users. Ecstasy users brush their teeth significant less frequently per day than non-recreational drug users. There were no significant differences in DMFT and in the devices used for brushing/interdental cleaning and frequency of use of these interdental devices between both groups.Conclusion Periodontitis, active caries lesions and xerostomia are more frequently present in recreational ecstasy users compared to age- and sex-matched non-users.

Background: Gastrointestinal diseases can have oral manifestations. The aim of this study was to investigate the knowledge of gastroenterologists and dentists about gastrointestinal diseases with oral manifestations and to assess the frequency, extent and content of communication between gastroenterologists and oral healthcare professionals. Methods: Separate questionnaires were developed and sent to all 523 gastroenterologists and a random selection of 500 dentists in the Netherlands. Both questionnaires contained questions about demographic characteristics of the participants, 10 statements about gastrointestinal diseases with possible oral manifestations and questions about the communication between gastroenterologists and oral healthcare professionals. Additionally, the questionnaire for gastroenterologists contained 9 statements about general dentistry and the questionnaire for dentist had 9 questions about gastrointestinal diseases. Results: Gastroenterologists answered 47.6% ± 31.9% of the questions correct about gastrointestinal diseases with possible oral manifestations and 57.5% ± 27.9% of the questions correct about general dentistry. Dentists answered 26.6% ± 20.5% of the questions correct about possible oral manifestations of gastrointestinal diseases and 50.3% ± 18.7% of the questions correct about gastrointestinal diseases. Gastroenterologists and dentists valued interdisciplinary consultation as very useful with scores of 4.07 ± 0.70 and 4.67 ± 0.49 on a 5-point Likert scale, respectively, but the frequency of consultation was considered insufficiently with a mean score of 2.88 ± 1.01 and 2.24 ± 1.05 on a 5-point Likert scale, respectively. Conclusions: This study suggests that the knowledge of gastroenterologists and dentists about gastrointestinal diseases with oral manifestations could be improved. Interdisciplinary consultation was considered valuable for the optimal treatment of their patients but was assessed as insufficient.
RESUMEN
OBJECTIVES: Numerous clinical and histopathological characteristics have been associated with malignant transformation (MT) of oral leukoplakia (OL), including classic and differentiated epithelial dysplasia, but MT predictions remain suboptimal. The objective of this study was to determine the annual MT rate of OL and to identify clinicopathological risk factors associated with MT. PATIENTS AND METHODS: 170 patients with OL were included in this retrospective cohort study, 117 females and 53 males. Follow-up ranged from 12 to 219 months (median 54). The analyzed variables included age, gender, smoking habits, clinical presentation, subsite, size and treatment. In a subgroup of 140 patients, histopathological diagnoses were reviewed with regard to the presence of dysplasia, discerning both classic dysplasia and differentiated dysplasia. RESULTS: MT occurred in 23% of the patients, resulting in an annual MT rate of 4.9% (95% CI: 3.5 - 6.6) which remained consistent. High-risk subsite (tongue and floor of mouth) was the only clinical predictor for MT (Hazard Ratio = 2.7, 95% CI: 1.3 - 5.5, p = 0.007). In 140 patients, classic dysplasia (Hazard Ratio = 7.2, 95% CI: 1.6 - 33.1, p = 0.012) and differentiated dysplasia (Hazard Ratio = 6.6, 95% CI: 1.2 - 25.4, p = 0.026) were predictors for MT. Binary grading between dysplasia and no dysplasia was significant for predicting MT (Hazard Ratio = 6.4, 95% CI: 1.5 - 27.5, p = 0.013). CONCLUSION: Since annual MT rate of OL remains stable during follow-up, regular long-term or even life-long follow-up is advocated. Specific oral subsites and epithelial dysplasia are predictors for MT of OL.

OBJECTIVES: Patients with inflammatory bowel disease have an increased risk of developing oral health problems. The aim of this study was to investigate whether oral diseases in these patients are related to inflammation of the intestine and if there is a correlation between inflammatory bowel disease-specific health-related quality of life (IBD-HR-QOL) and oral health problems. STUDY DESIGN: The study was a cross-sectional survey and analysis of self-reported oral health of individuals with a stoma for Crohn's disease (CD), ulcerative colitis (UC), and treated colon cancer (CC). Validated international questionnaires were sent to members of the Stoma Federation of The Netherlands. Because there was an unequal distribution of male and female patients with CD and CC, data of 169 age-matched female patients with CD, UC, and CC with a stoma were analyzed. RESULTS: Patients with CD had significantly more oral health problems compared with those with UC or CC. Patients with CD and UC both had significantly more gingival-related problems compared with patients with CC. There was a significant negative correlation between IBD-HR-QOL and oral health problems. CONCLUSIONS: In the 3 distinguishable groups of patients with a stoma, patients with CD had an increased risk for oral health problems, independently from surgical removal of (a part of) the inflamed intestine, suggesting a general increased susceptibility of patients with CD for oral health problems.

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. RESULTS: The maximum incidence was found in Zagreb (Croatia) (18%) and the minimum in Bergen (Norway) (0%). The most frequent mechanisms were car accidents, with 177 cases, followed by motorcycle accidents. The most frequently observed fracture involved the mandible, with 199 fractures, followed by maxillo-zygomatic-orbital (MZO) fractures. CONCLUSIONS: In all the 3 groups (car, motorcycle, and pedestrian), mandibular and MZO fractures were the 2 most frequently observed fractures, with some variations. The importance of analyzing MVA-related facial injuries and their features and characteristics should be stressed.

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.
