Abstract
BACKGROUND To assess the influence of diagnosis and referral provided by specialists in oral diagnosis on disease-free survival and overall survival of patients with oral cancer. METHODS A cohort of 282 patients with oral cancer treated at a regional cancer hospital from 1998 to 2016 was analyzed retrospectively. The referral register of the patients was analyzed and assigned to two groups: (1) those referred by oral diagnosis specialists (n = 129), or (2) those referred by nonspecialized professionals (n = 153). The cancer treatment evolution was assessed from the patients' records, and the outcome was registered concerning cancer recurrence and death. Sociodemographic and clinicopathological variables were explored as predictors of disease-free survival and overall survival. RESULTS Group 1 exhibited lower T stages and a reduced incidence of regional and distant metastases. Surgery was performed in 75.2% of cases in Group 1, while in Group 2, the rate was 60.8%. Advanced T stages and regional metastases reduced the feasibility of surgery. Higher TNM stages and tumor recurrence were associated with decreased disease-free survival, while surgical intervention was a protective factor. Higher TNM stage had a negative impact on the overall survival. CONCLUSION Specialized oral diagnosis did not directly impact disease-free survival and overall survival and did not influence the indication of surgery in oral cancer; however, it was associated with the diagnosis of early tumors and better prognosis.

Experiences, perceptions, and decision-making capacity towards oral biopsy among dental students and dentists. Sci Rep 2023; 13:22937. [PMID: 38129588 PMCID: PMC10739868 DOI: 10.1038/s41598-023-50323-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Accepted: 12/18/2023] [Indexed: 12/23/2023] Open
Abstract
The dentist plays a crucial role in identifying oral lesions as it is their responsibility to conduct the clinical examination for diagnosing diseases in this anatomical region. Dentists should be able to perform simple oral biopsies when this procedure is necessary. However, several studies point out that dentists lack experience and perceive themselves incapable of performing biopsies. This analytical cross-sectional study aimed to assess participants' experiences and perceptions regarding a continuing education activity focused on the biopsy procedure. The secondary aim was to evaluate their ability to determine when a biopsy is indicated. The sample consisted of 228 individuals: 143 dentists and 85 undergraduate dental students who completed questionnaires related to a lecture held in May/2021, as part of the continuing educational activities of the "Red May" Project. Participants completed two questionnaires: the first assessed their experience and self-confidence in performing oral biopsies, whereas the second evaluated their capacity to define when the biopsy is indicated by means the evaluation of 10 clinical cases. The results reveal no significant difference in the percentage of correct answers between dental students and dentists. Regarding the frequency of performing the biopsy procedure, most respondents (69.7%) reported doing so rarely or never. Furthermore, while 31.6% of the participants stated that they perform biopsies depending on the case, 68.4% prefer to refer patients to specialists, such as professionals in Stomatology/Oral Medicine. These findings highlight limitations in the educational preparation of the study population concerning biopsy procedures, oral lesions, and their management. They also indicate a concerning tendency to overestimate knowledge in this area. Thus, this study emphasizes the importance of continuing education and underscores the need to revise academic curricula and provide complementary education for all dental professionals.

Abstract
The objective of this study was to develop and validate an App for identifying risk factors for oral cancer. To this end, we developed an App (OCS: Oral Cancer Screening) with predictors of Oral Cancer (OC) and algorithm assembly to estimate the risk of its development. METHODOLOGY Simulated clinical cases were designed so that 40 professionals with expertise in oral diagnostics could validate the algorithm and test its usability (SUS: System Usability Score) and acceptability (TAM: Technology Acceptance Model). Cronbach's alpha coefficient, Friedman/Dunn tests, and Spearman correlation evaluated the SUS and TAM scales. ROC curve was plotted to estimate the cutoff point of the algorithm in suggesting a high risk for OCS of the simulated cases. Chi-square and Fisher's exact tests were additionally used (p<0.05, SPSS v20.0). RESULTS Professionals with expertise in oral diagnosis had usability of 84.63±10.66 and acceptability of 84.75±10.62, which correlated positively (p<0.001, r=0.647). Acting in clinical areas of dentistry (p=0.034) and history of performing OC risk factor orientation (p=0.048) increased acceptability while acting in higher education increased usability (p=0.011). The cutoff point suggested by the App after validation of the simulated clinical cases showed high sensitivity of 84.8% and lower specificity of 58.4%. CONCLUSION The OCS was effective and with adequate sensitivity, usability, and acceptability and may contribute to the detection of early oral lesions.

Abstract
Background: Oral cancer is a frequent neoplasm worldwide, and socioeconomic factors and access to health services may be associated with its risk. Aim: To analyze effect of socioeconomic variables and the influence of public oral health services availability on the frequency of new hospitalized cases and mortality of oral cancer in Brazil. Materials and Methods: This observational study analyzed all Brazilian cities with at least one hospitalized case of oral cancer in the National Cancer Institute database (2002-2017). For each city were collected: population size, Municipal Human Development Index (MHDI), Gini Coefficient, oral health coverage in primary care, number of Dental Specialized Centers (DSC) and absolute frequency of deaths after one year of the first treatment. The risk ratio was determined by COX regression, and the effect of the predictor variables on the incidence of cases was verified by the Hazard Ratio measure. Poisson regression was used to determine factors associated with higher mortality frequency. Results: Cities above 50,000 inhabitants, with high or very high MHDI, more unequal (Gini > 0.4), with less oral health coverage in primary care (<50%) and without DSC had a greater accumulated risk of having 1 or more cases (p < 0.001). Higher frequency of deaths was also associated with higher population size, higher MHDI, higher Gini and lower oral health coverage in primary care (p < 0.001). Conclusions: The number hospitalization and deaths due to oral cancer in Brazil was influenced by the cities' population size, the population's socioeconomic status and the availability of public dental services.

Abstract
Objectives The purpose of this project was to determine the level of mouth cancer awareness and to investigate the associated factors in a United Kingdom (UK) general population sample. Material and Methods Adult Dental Health Survey (2010) was conducted in a sample of 3,353 adult residents in the Grampian region of the UK (adjusted participation rate 58%). Participants completed a questionnaire consisting of questions on oral health, health behaviour, quality of life and cancer awareness. Results Overall, 81% of participants were aware of mouth cancer. This was associated with younger age, higher levels of education and better general health. Current smokers and alcohol drinkers were more aware of mouth cancer. When asked about risk factors for mouth cancer, the following were identified by the respondents: smoking (84%), poor oral hygiene (60%), drinking alcohol heavily (59%), poor diet (37%), stress (15%), being overweight (6%), drinking hot liquids (5%), eating spicy food (3%), using mouthwash (2%) and kissing someone (1%). Smokers were more likely to identify smoking as a risk factor for mouth cancer. Similarly, those who consumed alcohol almost daily were more likely to identify heavy alcohol drinking as a risk factor. Conclusions Awareness of mouth cancer is high in respondents from the general population, and participants were able to identify the most important risk factors. Knowledge of tobacco and alcohol as risk factors was highest amongst those exposed to them. The study proposed that the prevention strategies should focus not only on increasing knowledge, but also on changing health behaviour.

Abstract
OBJECTIVE The aim of the present study was to identify the profile of patients diagnosed with oral squamous cell carcinoma (SCC) and factors associated with the clinical stage of the disease. MATERIALS AND METHOD A cross-sectional study was conducted with a sample of 293 medical charts of patients with SCC treated at an oncology reference center in the city of Campina Grande (Brazil) between 2000 and 2006. Descriptive and inferential statistics were performed with robust Poisson regression (α=5%). RESULTS Males (56.6%), non-white individuals (49.0%) and individuals over than 60 years of age (74.1%) were the most affected by SCC. The tongue (35.1%) and palate (21.5%) were the most common sites. A large portion of the patients were smokers (37.6%) and 60.2% were in an advanced stage of the disease. Clinical staging was not associated with sex, age, skin color or drinking and/or smoking habits. CONCLUSION There was a higher incidence of SCC in men, older patients, non-white individuals and smokers. Clinical staging was not associated with the variables analyzed.

Abstract
The aim of this study was to assess oral cancer awareness among dentists who attended 101st FDI World Dental Congress, İstanbul, Turkey. Among 170 dentists who agreed to participate, there were 13 oral surgeons, 6 restorative dentists, 4 endodontists, 4 orthodontists, 6 periodontists, 5 pedodontists, and 14 prosthodontists. Knowledge of oral cancer risk factors and diagnosis procedures, dentists' attitude towards oral cancers, management practice regarding oral cancer, and oral cancer information sources were assessed using 25 questions. The data were analyzed with IBM SPSS Statistics 22.0 program. Among 170 participant dentists, there were 69 (40.6%) male dentists and 101 (59.4%) female dentists. Largest number of them identified tobacco (98.8%) and alcohol usage (91.2%), prior oral cancer lesions (95.3%), viral infections (90.0%), UV exposure (86.5%), and betel quid chewing (80.6%), and lower numbers reported older age (56.5%) and low consumption of fruit and vegetables (52.4%). Oral medicine specialists scored marginally higher in indicating erythroplakia and leukoplakia most likely to be precancerous and squamous cell carcinoma as the most common form of oral cancer (p < 0.01). This study highlighted the importance of improved educational methods for dentists on oral cancer detection and prevention.

Abstract
The present study assessed the level of dentists' knowledge regarding oral cancer in the city of São Paulo, Brazil. A questionnaire was used to compare the level of knowledge among newly graduated and senior clinicians. A total of 20,154 e-mails were correctly delivered to the dentists registered in the database of the Regional Dentistry Council of São Paulo, and 477 (2.36%) responses were received. This sample consisted of 84 newly graduated clinicians and 105 senior clinicians. For the statistical analysis, the chi-square test and the logistic regression analysis were performed with α = 0.05, and the results were described herein. According to their knowledge level, the results were statistically different between the groups, since 19% of the newly graduated clinicians were evaluated with knowledge grade A (excellent) in comparison to 6.7% of the senior clinicians. In spite of the results indicated that newly graduated clinicians' knowledge regarding oral cancer was 2.1 times higher, 34.5% of the professionals in this group had regular or poor knowledge on the subject, and several questions relating to clinical characteristics and risk factors indicated that there still exist some knowledge gaps, demonstrating that there is a need for further studies and information activities addressing oral cancer.

Abstract
The objective of this study was to assess the oral health status of users of illicit drugs such as marijuana and cocaine/crack and compare it with individuals not using these chemical substances. Questionnaires were applied to 35 illicit drugs users to gather information on demographic status, general health, and use of drugs. Then, a clinical assessment of the oral health condition was performed to collect data on decayed, missing and filled teeth (DMFT) index, salivary flow rate (SFR), and mucosal lesions. The control group was composed of 35 non-illicit drug users. In the experimental group, 91.43% were males, 80% were smokers, and 42.85% were alcoholics. Cocaine was the most common drug used (77.15%), followed by marijuana (68.6%), and crack (51.4%). The average DMFT index was 9.8 and the SFR was reduced in 60% of subjects. Mucosal alterations were detected, but no potentially malignant disorders or oral cancer were diagnosed. Compared to control group, significantly higher values for gender (40%, p = 0.0001), smoking (22.86%) and heavy drinking (5.7%) habits (p = 0.0001), SFR (31.4%; p = 0.0308), and oral lesions (p = 0.0488) were found for the experimental group, although significantly higher values were found in the control group for DMFT index (p = 0.0148). It can be concluded that the use of illicit drugs contributed to an increased prevalence of oral mucosa lesions. In addition, a decline on SFR and a reduced DMFT index was observed for illicit drug users.

Abstract
Background Oral cancer is a potentially fatal disease, especially when diagnosed in advanced stages. In Brazil, the primary health care (PHC) system is responsible for promoting oral health in order to prevent oral diseases. However, there is insufficient evidence to assess whether actions of the PHC system have some effect on the morbidity and mortality from oral cancer. The purpose of this study was to analyze the effect of PHC structure and work processes on the incidence and mortality rates of oral cancer after adjusting for contextual variables. Methods An ecological, longitudinal and analytical study was carried out. Data were obtained from different secondary data sources, including three surveys that were nationally representative of Brazilian PHC and carried out over the course of 10 years (2002–2012). Data were aggregated at the state level at different times. Oral cancer incidence and mortality rates, standardized by age and gender, served as the dependent variables. Covariables (sociodemographic, structure of basic health units, and work process in oral health) were entered in the regression models using a hierarchical approach based on a theoretical model. Analysis of mixed effects with random intercept model was also conducted (alpha = 5%). Results The oral cancer incidence rate was positively association with the proportion of of adults over 60 years (β = 0.59; p = 0.010) and adult smokers (β = 0.29; p = 0.010). The oral cancer related mortality rate was positively associated with the proportion of of adults over 60 years (β = 0.24; p < 0.001) and the performance of preventative and diagnostic actions for oral cancer (β = 0.02; p = 0.002). Mortality was inversely associated with the coverage of primary care teams (β = −0.01; p < 0.006) and PHC financing (β = −0.52−9; p = 0.014). Conclusions In Brazil, the PHC structure and work processes have been shown to help reduce the mortality rate of oral cancer, but not the incidence rate of the disease. We recommend expanding investments in PHC in order to prevent oral cancer related deaths.

Abstract
Some evidence suggests that the early detection of oral cancer (OC) during surveillance might improve survival rates. In addition to this, interventions aimed at enhancing public awareness and knowledge of signs, symptoms and risk factors of OC are thought to decrease the burden of disease. Nevertheless, there is much controversy with regard to the cost-effectiveness of population-based strategies for OC screening. Here, we present and briefly discuss timely findings that have put under scrutiny the applicability of approaches targeted at the early identification of patients with OC.

Abstract
This cross-sectional study evaluated the relationship between primary and secondary oral health care in Brazil. For this purpose, data from the National Program for Improving Access and Quality of Primary Care were used. Dentists from 12,403 oral health teams (OHTs) answered a structured questionnaire in 2012. The data were analyzed descriptively and by cluster analysis. Of the 12,387 (99.9%) OHTs that answered all the questions, 62.2% reported the existence of Dental Specialties Centers (DSCs) to which they could refer patients. The specialties with the highest frequencies were endodontics (68.4%), minor oral surgery (65.8%), periodontics (63.0%), radiology (46.8%), oral medicine (40.2%), orthodontics (20.5%) and implantology (6.2%). In all percentiles, the shortest wait time for secondary care was for radiology, followed by oral medicine and the other specialties. In the 50th percentile, the wait for endodontics, periodontics, minor oral surgery and orthodontics was 30 days, while for implantology, the wait was 60 days. Finally, in the 75th percentile, the wait for endodontics, orthodontics and implantology was 90 days or more. Two clusters, with different frequencies of OHT access to specialties, were identified. Cluster 1 (n = 7,913) included the OHTs with lower frequencies in all specialties except orthodontics and implantology compared with Cluster 2 (n = 4,474). Of the Brazilian regions, the South and Southeast regions had the highest frequencies for Cluster 2, with better rates for the relationship between primary and secondary care. This study suggests certain difficulties in the relationship between primary and secondary care in specific specialties in oral health, with a great number of OHTs with limited access to DSCs, in addition to different performance in terms of OHT access to DSCs across Brazilian regions.

Abstract
RATIONALE AND OBJECTIVE Central and South America comprise one of the areas characterized by high incidence rates for head and neck cancer. We describe the geographical and temporal trends in incidence and mortality of head and neck cancers in the Central and South American region in order to identify opportunities for intervention on the major identified risk factors: tobacco control, alcohol use and viral infections. METHODS We obtained regional- and national-level incidence data from 48 population-based cancer registries in 13 countries and cancer deaths from the WHO mortality database for 18 countries. Age-standardized incidence (ASR) and mortality (ASMR) rates per 100,000 person-years were estimated. RESULTS Brazil had the highest incidence rates for oral and pharyngeal cancer in the region for both sexes, followed by Cuba, Uruguay and Argentina. Cuba had the highest incidence and mortality rates of laryngeal cancer in the region for males and females. Overall, males had rates about four times higher than those in females. Most countries in the region have implemented WHO recommendations for both tobacco and alcohol public policy control. CONCLUSION Head and neck squamous-cell cancer (HNSCC) incidence and mortality rates in the Central and South America region vary considerably across countries, with Brazil, Cuba, French Guyana, Uruguay and Argentina experiencing the highest rates in the region. Males carry most of the HNSCC burden. Improvement and implementation of comprehensive tobacco and alcohol control policies as well as the monitoring of these factors are fundamental to prevention of head and neck cancers in the region.
