Level of awareness of oral cancer and oral potentially malignant disorders among medical and dental undergraduates.

The aim of this study was to investigate the awareness of oral potentially malignant disorders (OPMD) and oral cancer among medical and dental students of the University of Peradeniya. A pre-tested, self-administered questionnaire was used among 1006 students. Majority were medical students (74.3%), females (60.5%), and in the second year (25.2%). About 54% of respondents had poor knowledge. Dental students had a significantly higher knowledge and female students showed greater awareness. About 90% of medical students had never examined a patient with OPMD, and 79.5% of them had not examined one with oral cancer. Medical undergraduates must receive adequate education about OPMD and cancer.

Living in limbo: Ethics and experience in a conversation about persistent oral lesions.

This case report presents a conversation that the authors had with a patient who is suffering from oral lichen planus and oral cancer. The reason that the authors approached the patient for an interview was to find out why he decided to enroll in an experimental study related to his oral cancer. The patient reported that it was "the waiting" that led him to enroll in this study--that is, the pressure of waiting for oral cancer to reemerge was simply unbearable, and enrolling in this experimental study enabled him to take a more proactive approach to his illness. The authors view this "waiting" as a "limbo experience" and reflect on the implications of this limbo experience for dental ethics and research ethics.

Patients' awareness of the potential benefit of smoking cessation. A study evaluating self-reported and clinical data from patients referred to an oral medicine unit.

The present study analyzed history of smoking and willingness to quit smoking in patients referred for diagnosis and treatment of different oral mucosal lesions. Prior to the initial clinical examination, patients filled in a standardized questionnaire regarding their current and former smoking habits and willingness to quit. Definitive diagnoses were classified into three groups (benign/reactive lesions, premalignant lesions and conditions, and malignant diseases) and correlated with the self-reported data in the questionnaires. Of the 980 patients included, 514 (52%) described themselves as never smokers, 202 (21%) as former smokers, and 264 (27%) as current smokers. In the group of current smokers, 23% thought their premalignant lesions/conditions were related to their smoking habit, but only 15% of the patients with malignant mucosal diseases saw that correlation. Only 14% of the smokers wanted to commence smoking cessation within the next 30 days. Patients with malignant diseases (31%) showed greater willingness to quit than patients diagnosed with benign/reactive lesions (11%). Future clinical studies should attempt (1) to enhance patients' awareness of the negative impact of smoking on the oral mucosa and (2) to increase willingness to quit in smokers referred to a dental/oral medicine setting.

Impact of chronic oral mucosal disease on daily life: preliminary observations from a qualitative study.

OBJECTIVE: To explore the experience of daily life of persons with chronic oral mucosal conditions. METHODS: Purposive sampling was used to recruit patients from the Oral Medicine Unit of Cork University Dental School and Hospital. An experienced independent facilitator convened the focus groups and conducted individual interviews in a non clinical setting. Focus groups were mixed with regard to gender, age, chronic oral mucosal condition, time since diagnosis and severity. A total of 24 patients took part, including patients with oral lichen planus, mucous membrane pemphigoid, pemphigus vulgaris, recurrent aphthous stomatitis and orofacial granulomatosis. RESULTS: Analysis of the interviews revealed that patient views could be divided into the following themes - biopsychosocial issues, treatment limitations and side effects, unpredictability of the conditions and the potential for malignant transformation and issues for the healthcare professionals. CONCLUSION: Chronic oral mucosal conditions impact upon the experience of daily life of patients in a variety of areas from physical health and functioning, to concerns about their future. The role of the oral medicine practitioner in treating patients with chronic oral mucosal diseases extends beyond active management and symptomatic relief to the management of all aspects of these conditions that impact upon their daily lives.

Psychiatric morbidity among patients with oral sub-mucous fibrosis: a preliminary study.

BACKGROUND: Oral submucous fibrosis (OSF) is a chronic oral mucosal condition with pre-malignant potential. The association between psychiatric morbidity and OSF has been sparsely studied. METHODS: This cross-sectional study included 33 consecutive subjects clinically diagnosed with OSF who attended an academic tertiary care dental centre. General Health Questionnaire-28 was administered to assess the psychological morbidity. Dependence to areca products was assessed using the ICD-10 criteria. Patient group was compared with an age and gender matched control group (n=33) from the same hospital that comprised patients who had dental diseases other than OSF and had no areca/tobacco habit. RESULTS: Total mean scores (SD) of GHQ-28 for study group and control group respectively were 48.2 (18.1) vs. 24.2 (6.5) (P<0.001). Among the patient group, the mean total GHQ scores were significantly higher in those with functional stage C (those with worst functional staging) of OSF 63.4 (15.2) when compared with those with stage B 54 (14.2) and stage A 38.7 (17) (d.f.=2; P=0.005). 22 (66.7%) of patients met ICD-10 criteria for dependence to areca products. CONCLUSIONS: OSF may be associated with considerable psychological morbidity. This morbidity may be significantly more in patients with worst functional staging. It is difficult to determine whether this is the cause or effect of the disease. Further systematic studies are urgently needed to address this issue.

Web-based information on oral dysplasia and precancer of the mouth - Quality and readability.

OBJECTIVES: The numbers of individuals with oral cancer are increasing. This cancer is preceded by oral epithelial dysplasia (OED). There remains no detailed study of the online information presently available for patients with OED or indeed what information such patients may require to be appropriately informed regarding their condition. Hence, the aim of the present study is to assess the patient-oriented web content with respect to OED. METHODS: The first 100 websites yielded from nine searches performed using different search terms and engines were considered. These were assessed for content, quality (DISCERN instrument, Journal of the American Medical Association benchmarks, and Health on Net seal) and readability (Flesch Reading Ease Score and Flesch-Kincaid Grade Level). RESULTS: There was a general scarcity of OED content across the identified websites. Information about authors, sources used to compile the publication, treatment, and shared decision were limited or absent. Only 6% and 27% of the websites achieved all the four JAMA benchmarks and HON seal, respectively. The average readability level was at 10th grade (US schools), which far exceeds the recommended levels of written health information. CONCLUSION: At present patients seeking information on OED are likely to have difficulty in finding reliable information from the Web about this disorder and its possible impact upon their life. Further work is thus required to develop a web-based resource regarding OED that addresses the shortfalls demonstrated by the current study.

Knowledge of Oral Precancerous Lesions Considering Years Since Graduation Among Dentists in the Capital City of Iran: a Pathway to Early Oral Cancer Diagnosis and Referral?

Background: Late diagnosis and improper treatment lead to many avoidable deaths in patients suffering from oral cancer. This study evaluated the knowledge and perceptions of general dentists regarding oral precancerous lesions and oral cancer risk factors with reference to early diagnosis and referral. Materials and Methods: In this descriptive study, 200 private general dental practitioners were randomly selected in Tehran, Iran. Demographic information and years since graduation were recorded; knowledge levels were evaluated with a standardized questionnaire consisting of 15 closed-response item questions about precancerous lesions and oral cavity cancer. Each correct answer got one point. Results: Out of 200 selected dentists, 153 returned completed questionnaires. The average age of participants was 36 and the average achieved score was 7.96 out of 15 (Min 3, Max 13). Most (64.7%) of participants were in the group that graduated within the previous 10 years, 23.5% between 10 and 20 years since graduation, and 11.8% more than 20 years previously. There was a statistically significant difference between the most recently graduated group (< 10 years) and the other two groups. The dentists' awareness was also significantly dependent on age. There was no statistically significant difference in awareness between male and female dentists. Conclusion: As professional oral health care providers, dentists should be aware of all aspects regarding precancerous lesions in order to optimize early diagnosis and referral of oral cancer patients. Training courses and continuing education seem to be an essential strategy to increase and maintain knowledge of this group.

Assessing oral cancer knowledge among dental students in South Carolina.

BACKGROUND: Because South Carolina has the fourth highest mortality rate for oral cancer among the 50 states, dental students in the state must be knowledgeable about prevention and early detection of the disease. METHODS: In 2002, the authors surveyed 163 students using a written questionnaire (response rate, 79.1 percent). The questionnaire included questions about oral cancer risk and nonrisk factors as well as oral cancer diagnostic signs, symptoms and examination procedures. The authors performed univariate and bivariate analyses (alpha < or = .025). RESULTS: At least 93 percent of the students replied that tobacco, alcohol and previous oral cancer lesions were risk factors. One hundred six students (65 percent) knew that the most likely site for oral cancer is the ventrolateral border of the tongue. Students differed in their overall knowledge of risk factors (P = .002), nonrisk factors (P < .001) and diagnostic procedures (P < .001). CONCLUSION: Although students' level of knowledge increased with academic year, educators and policy-makers need to place greater emphasis on oral cancer education and training in dental schools. PRACTICE IMPLICATIONS: Morbidity and mortality are likely to be reduced if dentists know how to prevent and detect oral cancer.

Awareness and Knowledge of Oral Cancer and Potentially Malignant Oral Disorders among Dental Patients in Far North Queensland, Australia.

BACKGROUND: Public awareness/knowledge on oral and pharyngeal cancer (OPC), potentially malignant disorders (PMODs) and their risk factors is crucial for prevention and early detection of OPC and PMODs. Yet, there are no published data available on the awareness and knowledge of OPC and PMODs among people living in Far North Queensland, Australia. MATERIALS AND METHODS: This study was conducted as a cross sectional survey. A self-administered questionnaire was designed and consisted of relevant questions to ascertain socio-demographic information, awareness and knowledge of OPC, PMODs and risk factors and questions on participant's exposure to risk factors and dietary history were also included. Survey was carried out at the Dental Clinic of the James Cook University School of Dentistry (JCU Dental), Cairns, Australia. Subjects above the age of 20 years (n=366) were randomly selected during the period from 31st July to 6th September 2013 and questionnaire was distributed to complete while they are waiting for treatment. Data analysis was carried out using SPSS version 21 and the chi -squared test was employed to compare groups. P<0.05 was considered statistically significant. RESULTS: The study revealed that 52.3% of the respondents were aware of the existence of OPC but only 19.0% were aware of PMODs. Of those who were aware of oral cancer, 92% agreed or strongly agreed that smoking is a strong risk factor for OPC. Similarly a relatively high proportion of the respondents agreed or strongly agreed that tobacco chewing (84%), tobacco chewing with areca nut (68%), chewing areca nut alone (51%) and exposure to actinic radiation (71%) as risk factors. However, the results for alcohol intake, age, and HPV infection were found to be relatively poor with proportions 33%, 34%, and 23% respectively. CONCLUSIONS: This study revealed an alarming lack of awareness and knowledge of OPC and PMODs.

Psychoneuroimmunology in oral biology and medicine: the model of oral lichen planus.

Rheumatoid arthritis involves psychoneuroendocrine-immunopathological comorbidities. In the stoma, patients with rheumatoid arthritis frequently show signs of periondontal disease consequent to elevated levels of crevicular proinflammatory cytokines. It is not clear whether rheumatoid arthritis may manifest in association with immunopathological manifestations of the oral soft mucosa. Oral lichen planus (OLP), first described by E. Wilson in 1859, is a T-cell-mediated inflammatory disease whose lesions characteristically lack B cells, plasma cells, immunoglobulin. or complement. It is increasingly well characterized and recognized as a model for psychoneuroimmunology research in oral biology and medicine. To date, we have shown an association between changes in hypothalamic-pituitary-adrenal (HPA) regulation, systemic markers of cellular immunity and mood states, with clinical stages of OLP (i.e., atrophic vs. erosive vs. bullous lesions). We report significant associations (p < 0.05) between the stage of OLP, HPA deregulation, and altered distribution and functional responses of naïve CD4(+) cells. We emphasize the need to study in greater details the psychoneuroendocrine-immune inter-relationships in OLP, and we propose a novel neuroimmune hypothesis for OLP.

[Tobacco-associated lesions of the oral cavity and motivation for smoking cessation: a study of 121 cases]. / Lésions buccodentaires dues au tabac et motivation au sevrage : etude de 121 cas.

UNLABELLED: Tobacco use produces many changes to the oral cavity including non-malignant, precancerous, and malignant lesions. Most of these oral lesions and changes can be detected by a simple visual inspection of the oral cavity. METHODS: We evaluated the motivation for smoking cessation of patients with oral lesions. RESULTS: Visual inspection of the oral cavity in 121 patients made 58 % of them motivated to smoking cessation. DISCUSSION: Inspection of oral cavity showing lesions caused by tobacco is a good way to initiate tobacco cessation.

Oral mucosal lesions and risk habits among men in an Italian study population.

A randomly selected study population of 118 male subjects (> or = 40 years) living on the Mediterranean island of Pantelleria (southwest of Sicily, Italy) was examined for the presence of oral mucosal lesions, with particular emphasis on the early diagnosis of oral precancerous and cancerous lesions. The study population was interviewed for socioeconomic and behavioural information, and clinically examined using WHO criteria. The prevalence of oral mucosal lesions observed, and data obtained about oral hygiene, tobacco smoking, alcohol drinking and exposure to actinic radiation, were analysed. Alcohol drinking was the most common habit in the study population (73%), followed by tobacco smoking (58.5%, of whom 96% were cigarette smokers). Only 3% showed good oral hygiene and 25% were edentate. Oral lesions were observed in 81.3% of the study group, mainly coated tongue (51.4%), leukoplakia (13.8%), traumatic oral lesions (traumatic ulcers and frictional white lesions) in 9.2%, actinic cheilitis (4.6%), and squamous cell carcinoma in one case (0.9%). Statistically significant associations were found between the prevalence of coated tongue and tobacco smoking (P<0.0001), and between the prevalence of actinic cheilitis and tobacco smoking/alcohol drinking (P<0.05). Analysis of clinical and anamnestic data underlined the effective presence, in the population examined, of the behavioural risk factors for oral precancerous and cancerous lesions, and the lack of cultural motivation towards primary prevention activities, such as the elimination of risk habits.
