Devising a pro forma for dental screening of patients before invasive cardiac surgery.

Certain types of invasive cardiac surgery can place patients at risk of developing infective endocarditis from dental pathology or dental treatment. University Hospital Bristol and Weston NHS Foundation Trust is the regional centre for cardiac surgery in the South West of the UK and is part of the South Wales and South West Congenital Heart Disease Network. As part of this network, the Special Care Dental Department within Bristol Dental Hospital provides dental screening for patients pending invasive cardiac surgery. These are conducted to identify dental pathology in individuals who will be at risk of infective endocarditis, so where possible, they are rendered dentally fit before their surgery.Presented is the information that led to the creation of a screening pro forma, for the dental assessment of patients before invasive cardiac surgery, suitable for use in primary or secondary care. This was produced following an audit, to ensure that along with identifying sources of dental pathology, the dental screening is also documenting the risk of dental pathology and modifiable risk factors. This enables tailored preventative advice which is important to help reduce a patient's lifetime risk of infective endocarditis from dental pathology. Other information used to help develop the pro forma taken from the audit, regional and national guidance is also discussed.

Effect of dental screening on cardiovascular risk: A nationwide cohort study.

To evaluate the effect of dental screening on the risk of cardiovascular disease (CVD) using data from a nationwide population-based cohort. This retrospective cohort study extracted data of 478,245 individuals aged 40-79 years who participated in a health screening programme during 2002-2003 from the National Health Insurance Service-National Health Screening Cohort. Based on screening experience, participants were classified into the non-screening, general screening only, and dental screening groups. Using Cox proportional hazard models, hazard ratios (HRs) were determined for major adverse cardiovascular events (MACE) during each group's 11-year follow-up period. The risk of MACE in the dental screening group was 10% lower than that in the non-screening group (adjusted HR, 0.90; 95% confidence interval [CI], 0.87-0.93; p < .001) and 9% lower than that in the general screening only group (adjusted HR, 0.91; 95% CI, 0.89-0.94; p < .001). Dental screening was associated with a lower MACE risk; however, decreases in CVD-related healthcare utilization and costs were not clinically significant. The association could be attributed to healthy habits of participants in the dental screening group; nevertheless, it is conceivable that the improvement of oral health through dental screening influenced CVD prevention.

Implementation and Effectiveness of School-Based Dental Screening

The majority of children and youth attend school, and timely detection of health and developmental difficulties through school-based dental screening offers a chance for prompt intervention, enabling kids to attain their full potential in terms of development and functional health. Delays in prompt intervention incur significant financial, social, and personal costs for the community, government, and healthcare infrastructure. School-based dental screening initiatives have the ability to get around many of the logistical challenges that vulnerable communities face when trying to get primary preventative dental care. Additionally, schools have the power to influence cultural norms surrounding healthy habits and connect families to care systems. To screen for dental illness and conditions, a visual dental examination of school aged children is used. Parents of children who test positive are notified and urged to send their child to a primary care facility for additional testing of their child's dental health condition and any required medical care. Consequently, screening has two goals: to recognize test-positive cases, and to guarantee that these are followed up on for the proper management. School-based dental screening is typically a component of school health services, and its model, procedure, and goals differ based on the national policies of each country's healthcare delivery system. Effectiveness research has shown that school dental screening has not been highly successful in the study groups at reducing untreated dental caries in either the primary or permanent dentition of young children. Additionally, population-level dental attendance has not been found to increase by screening. Limited number of positively-screening children have been observed to visit a dentist post screening. Among the small percentage of the positively-screening students who visit a dentist, only a fraction has been noted to go on to receive the necessary care in follow-ups.

Pediatrician Knowledge, Attitude and Practices on Children's Oral Health in a Tertiary Public Hospital in the Philippines: A Descriptive Study.

Dental caries is a tolerated and overlooked chronic disease in the Philippines. The 2018 National Survey on Oral Health of the Department of Health found that 85.2% of Filipino children aged five years old have dental caries. Prevention and management of this disease can be established early with better collaborations between dental professionals and pediatricians who generally see children promptly in their well-baby check-ups. The study aimed to evaluate pediatricians' knowledge, attitude, and practices on dental caries prevention among their child patients. A cross-sectional descriptive study was conducted in March 2017 among pediatricians working in a tertiary public hospital in Metro Manila through a self-administered questionnaire. The questionnaire gathered data on knowledge about dental caries prevention, attitude towards the importance of dental screening and oral hygiene instructions, and dental health practices. Among the 122 participants, 67.8% scored high in the oral health knowledge part, 85.0% revealed a positive attitude toward dental caries prevention, and many claimed that they frequently included dental caries risk assessment and preventive oral health education in their clinical practices. Most pediatricians had high knowledge and a positive attitude toward dental caries prevention, although responses varied in the practice component. It will be valuable to continue improving the oral health proficiency of pediatricians to benefit early dental caries prevention in young patients.

Prevalence of Molar Incisor Hypomineralization in over 30,000 Schoolchildren in Switzerland.

To quantify the prevalence of Molar Incisor Hypomineralization (MIH) in the canton of Geneva, Switzerland. Thirty-eight dentists of the state school dental services were trained to detect and classify MIH cases. All children (32,142) from age 4 to 12 were examined during the annual dental screening offered by the state. Cases were scored as mild, moderate or severe. The prevalence of hypomineralizations was found to be 7.45% when all hypomineralized teeth were taken into consideration. MIH cases were found to be at 6.6%. Out of the MIH cases, 51% scored as mild, 36% as moderate and 13% as severe. The mean prevalence of MIH in Geneva school children was found to be 6.6%. This seems to be lower than the European and the global average. However, with almost half cases being moderate or severe, asserting a proper management protocol is necessary.

Immune Thrombocytopenic Purpura – A Case Report and Narrative Review

An autoimmune bleeding disorder, formerly known as idiopathic thrombocytopenic purpura is characterized by isolated thrombocytopenia which is not associated with any other systemic illnesses. ITP in adults is often considered an autoimmune disorder, as the body produces antibodies that damage some of its own products-in this case, blood platelets. It is recorded that immune thrombocytopenic purpura occurs in about 2 in 1,00,000 adults. The course is more chronic although spontaneous remission can also occur within months of initial diagnosis. A thorough and timely workup of thrombocytopenia is necessary as it is considered as a diagnosis of exclusion to rule out other differentials of ITP. The present case report emphazises a case report and review on immune thrombocytopenic purpura in a 24- years old female who was identified in our hospital who visited for a normal dental screening

Reviewing Teledentistry Usage in Canada during COVID-19 to Determine Possible Future Opportunities.

During the COVID-19 pandemic, the limited in-person availability of oral health care providers resulted in an unprecedented utilization of the teledentistry tool. This paper reviews how Canadian organizations supported teledentistry and what can be expected about its usage in the post-pandemic era. An environmental scan across relevant Canadian federal, provincial, and territorial organizations was conducted to review pertinent publicly available documents, including dental regulators’ or associations’ COVID-19 guidance documents, government documents, and media articles. Almost all jurisdictions promoted teledentistry for triaging dental emergencies and screening patients for COVID-19 symptoms but not even half of them have developed guidelines in terms of modalities of usage, handling of personal information, informed consent process, or maintaining standards of practice. During the COVID-19 recovery phase, these advances across Canada will support in developing a comprehensive guidance for teledentistry and possibly specific codes for its utilization. This can create a niche for teledentistry as an adjunct to the main stream dental care delivery where some visits can always be accommodated virtually, reducing disparities in oral healthcare between rural and urban communities. Ultimately, this can potentially make oral health care delivery more effective, efficient, and environmentally friendly in Canada.

A nationwide cohort study on growth impairment by cleft lip with or without palate

There are very few nationwide studies discussing the height, weight, head circumference, and dental screening of children with cleft lip with or without palate (CL/P), with most reports on this subject based on a 1900s cohort. This study aimed to characterize CL/P children in the 2000s in terms of height, weight, head circumference, and dental screening. This nationwide population-based study evaluated the National Health Insurance Service-Infants and Children’s Health Screening (NHIS-INCHS), specifically the height, weight, and head circumference of millions of children. Dental screening data, including the status of each tooth and comprehensive dental judgment, were also evaluated. Syndromic and nonsyndromic CL/P children had lower height, weight, and head circumference than no CL/P children until the age of 66–71 months. Children with cleft palate only or both cleft lip and palate showed similar results. Regarding dental screening, the primary teeth of CL/P children erupted later and fell out faster than no CL/P children. Dental caries was also more common in CL/P children. Children with CL/P had inferior general growth, regardless of palatoplasty surgery. More aggressive dental treatment was required for CL/P children due to the instability of primary teeth and tendency for caries.

Early Childhood Caries in 4- to 5-Year-Old Children in Erzurum, Turkey.

Introduction: Early childhood caries is tooth decay seen in children under 72 months old. It is associated with multiple predisposing factors and has a negative impact on quality of life. In this study, our aim was to assess the oral health conditions and prevalence of early childhood caries (ECC) in children in the city of Erzurum, Turkey.Materials and Methods: This cross-sectional epidemiological study was conducted in Atatürk University, Faculty of Dentistry, Pediatric Dentistry Department/Erzurum-Turkey, in the 2015–2016 academic year. A total of 1,156 children (588 girls and 568 boys), with mean age of 4.9 ± 0.3 years (min 4, max 5) were included in the study. Restorative index (RI), deft, significant caries index (SiC), SiC10, treatment needs, number of lost primary teeth per 100 children, care index, and prevalence of carious primary teeth were evaluated. Data were analyzed by Chi-square test and Mann–Whitney U test (p < 0.05).Results: A total of 73.3% prevalence of ECC was observed in preschool children with a mean deft score of 3.9±4 and an increase in ECC with age. RI was 2.2%, SiC was 8.5, SiC10 was 12.3, caries treatment needs was 93.5%, care index was 2.1%, and number of lost primary teeth per 100 children was 0.9 tooth.Conclusion: High level of ECC indicates the necessity of starting an oral health education program for mothers and dental screening of children, and the demand for improving oral and dental services.

Relationship of Personal Hygiene and BMI with OHI-S Scores among Primary School Children in a District in North India

INTRODUCTION: Malnutrition, among children can lead to various morbidities, and some of its consequences can be fatal. AIM: To assess Hygiene with Nutrition &amp; Morbidity among school children in district Ambala, Haryana, India. MATERIALS AND METHOD: Data was collected through a health check-up program for primary school children studying in class I and class III (aged only between 6-9 years) using a pre-tested and pre-designed questionnaire, weighing scale, measuring tape and dental screening instruments. The investigators were duly standardized and concerned instruments were duly calibrated. No names and personal information was collected and before the student was sent for examination, his I-card was removed. Data cleaned and analyzed using SPSS version 22.0. Shapiro wilk-test for data normalcy revealed a parametric distribution of the data and hence, the student’s t-test and multiple logistic regression were applied. RESULTS: The study included 216 males and 106 females, and the maximum unfavourable score (unclean hands, feet and skin) was observed in 40.1% of the children. Difference between favourable and unfavourable scores with OHI-S ≤2 was found to be 65.3% (p=0.02) and maximum students (68.9%), reported having a good favourable OHI-S score (p=0.01). It was observed that maximum males (43.1%) and females (48.1%) belonged to the “Normal” category of BMI, while lesser females (6.7%) were overweight in comparison to their male counterparts. Multivariate logistic regression revealed that OHI-S scores were significantly associated with BMI status (p=0.05) of the children, indicating that children with higher BMI scores have a tendency to have “fair” and “poor” OHI-S scores. CONCLUSION: Based on the results, appropriate measures can be undertaken to ensure that schools as well as healthcare professionals undertake more stringent measures to educate parents, children as well as teachers regarding the relationship between poor oral health and increased BMI values.

Effectiveness of School Dental Screening to Reduce Untreated Caries: A Cluster-Randomized Controlled Trial

The aim of the study was to evaluate the effectiveness of dental screening plus referral to a specific treating facility (intervention arm) against screening plus advice letter to see a dentist (traditional screening, and control arm) on changes in untreated caries among primary schoolchildren. A cluster-randomized, assessor-blinded, controlled trial was conducted in 16 public schools in Riyadh city, Saudi Arabia. Children aged 6–11 years without any compromising medical condition were eligible for inclusion. Children were examined for dental caries at baseline and 12 months later. Parents reported their socio-demographic characteristics and their child use of dental services at baseline and follow-up. Differences in the number of decayed primary and permanent teeth between trial arms were assessed using 3-level mixed-effects models to account for the clustering of children within schools and baseline demographic differences between arms. Data from 1,098 children (537 in the intervention and 561 in the control arm) were analysed. In the mixed-effect model, no differences in the increment of decayed primary and permanent teeth were found between the intervention and control arms (rate ratio: 0.88; 95% CI: 0.53–1.06). No differences between arms were found in the proportion of children visiting the dentist either (secondary outcome). The findings of this trial provided no support for the effect of post-screening referral to a specific dental hospital, compared to traditional screening, on changes in untreated dental caries among primary schoolchildren.

Association between first oral examination characteristics and dental treatment needs in privately insured children: A claims data analysis

BackgroundEarly childhood caries (ECC) remains the most common, preventable infectious disease among children in the United States. Screening is recommended after the eruption of the first tooth, but it is unclear how the age at first dental examination is associated with eventual restorative treatment needs. The authors of this study sought to determine how provider type and age at first dental examination are associated longitudinally with caries experience among children in the United States. MethodsDeidentified claims data were included for 706,636 privately insured children aged 0 through 6 years as part of the nationwide IBM Watson Health Market Scan (2012-2017). The authors used Kaplan-Meier survival analysis to describe the association between the age of first visit and restorative treatment needs. ResultsA total of 21% of this population required restorative treatment, and the average age at first dental examination was 3.6 years. A multivariable Cox proportional hazards model showed increased hazard for restorative treatment with age at first dental visit at 3 years (hazard ratio, 2.05; 95% CI, 1.97 to 2.13) and 4 years (hazard ratio, 3.99; 95% CI, 3.84 to 4.16). ConclusionThe high proportion of children requiring restorative treatment and late age at first dental screening show needed investments in educating general dentists, medical students, and pediatricians about oral health guidelines for pediatric patients. Practical ImplicationsCommunicating the importance of children establishing a dental home by age 1 year to parents and health care professionals may help reduce disease burden in children younger than 6 years.

Effect of Oral Health Promotion on Caries Experience and Oral Cleanliness of School Children in Kerung, Nepal: A Prospective 6-month Follow-Up Study.

A longitudinal oral health promotion project on caries experience and oral cleanliness was performed in a remote village in Nepal. The aim of this 6-month prospective survey was to investigate the impact of an oral health promotion project on caries experience, oral health-related behaviour, and general knowledge about oral health in Kerung, a remote village in Nepal. A prospective study was conducted in a convenience sample of children from the local school in Kerung. At baseline and after six months, dental plaque scores and caries experience scores were measured by calibrated examiners. Validated questionnaires on oral health habits and knowledge on oral health were taken. In addition, an oral health promotion program was developed. At baseline, 359 children were included, of which 266 could be surveyed after six months. A statistically significant decrease in the mean plaque score was found at after six months with a higher reduction for boys. A significant decrease in caries prevalence, as well as a significant increase in knowledge about oral health, was observed. Furthermore, after six months there were significantly more children reporting that they brushed their teeth for at least two minutes. Dental screenings and a comprehensive educational program resulted in a significant improvement of oral health.

Comparison of a full arch digital photographic assessment of caries prevalence in 5-year-old children to an established visual assessment method: a cross-sectional study

IntroductionDigital epidemiology in dental disease screening has a number of advantages which warrant further exploration.AimThis study aimed to test the examination accuracy of digital images to evaluate child oral health by comparing the new method to a gold standard method. It also investigated the levels of diagnostic accuracy between different examiners, including dental care professionals and a lay examiner, when quantifying dental disease using images.MethodsA calibrated dental examiner inspected forty 5-year-olds. In addition, three sets of digital images were taken per child. These images were assessed by six examiners. Sensitivity and specificity of caries diagnosis and inter-examiner reliability were calculated to compare the caries scores derived from examination of the images to those of the gold standard examinations.ResultsThe mean values for sensitivity and specificity scores were 48.0% and 99.1%, respectively. The mean value for kappa showed moderate agreement between 0.43 and 0.73 (0.57). Mean values for agreement using intra-class coefficients were excellent (0.78) and good (0.73) for dt and dmft, respectively. No statistical difference in the validity of the caries scores was shown between the different image assessors.ConclusionsThese data demonstrate the feasibility of using digital images to screen child oral health and for nondental professionals to be recruited to carry out digital epidemiology for the oral health surveillance of children.

Comparative Evaluation of Salivary Sialic Acid Levels Among Beedi Rollers and Tobacco Users in Mangalore, South India.

Introduction: According to World Health Organization, the global cancer burden is estimated to have risen to 18.1 million new cases and 9.6 million deaths in 2018. Tobacco use is a leading cause of cancer and of death from cancer. Beedis are the most popular smoking form of tobacco in India. Thirty-four percent of the tobacco produced in India is used for making beedis. The beedi sector is agroforestry-based and the second largest industry in India with approximately 4.4 million full-time beedi workers in India. Toxic constituents present in tobacco are released into the ambient air during the processing of beedis.Methods: A descriptive cross-sectional study was conducted to assess and compare salivary sialic acid levels among beedi rollers, tobacco smokers, smokeless tobacco users and individuals with no tobacco exposure. The study sample comprised of 140 individuals who were 30 to 60 years old, who attended dental screening and treatment camps in rural and urban areas in Mangalore, conducted by the Department of Public Health Dentistry, Yenepoya Dental College and patients who visited the Department of Oral Medicine and Radiology of Yenepoya Dental College. Saliva was collected by passive drool method into a sterile container. Biochemical analysis of salivary sialic acid was done using the acidic ninhydrin method. Continuous variables are expressed in terms of mean and standard deviation. Categorical variables are expressed in terms of frequencies and percentages. To compare salivary sialic acid levels between the groups ANOVA was used. The Chi-square test was used to compare categorical variables between the groups.Results: A total of 140 participants, 35 beedi rollers, 35 smokers, 35 smokeless tobacco users and 35 individuals with no tobacco exposure participated in the study. Among the 140 participants, 90 participants were males and 50 participants were females. There was a statistically significant difference in the mean salivary sialic acid level between the different groups (p<0.001) with smokeless tobacco users having the highest (10.60 mg/dL) mean salivary sialic acid level. It was found that the mean salivary sialic acid level reduced as the age progressed, even though there was no statistically significant difference. There was a statistically significant difference in the mean salivary sialic acid level between the different groups (p=0.010) with participants with 11 to 20 years of exposure to tobacco having the highest (8.67 mg/dL) mean salivary sialic acid level and participants with no tobacco exposure having least (3.06 mg/dL) mean salivary sialic acid level.Conclusion: The salivary sialic acid level was more in beedi rollers than individuals with no tobacco exposure, even though the difference was not statistically significant. The results showed elevated levels of salivary sialic acid in smokeless tobacco users followed by tobacco smokers. This may be an indication that smokeless tobacco use has harmful effects similar to or more than tobacco smoking since salivary sialic acid levels in smokeless tobacco users were higher than those in smokers.

Assessment of the oral cancer control activities through care seeking behavior of hospital attendees and their level of awareness

Oral cancer is the most common cancer among males in the Sri Lankan population. The aim of this study was to assess the health seeking behaviors and associated factors for OPMD.A hospital based descriptive cross-sectional study was conducted among Out Patients Department attendees of the Institute of Oral Health, Maharagama, from July 1, 2018 to December 31, 2019 by administering a questionnaire followed by an intra oral examination.The total number of 110 OPMD/oral cancer patients were identified. Awareness on OPMD was that 40 ​%. Majority were unaware of the danger of areca nut and alcohol use. Out of the identified cases during oral examination, 47.3 ​% were incidental findings while only 7.3 ​% were referred by the General Medical Practitioners (GMP). None were referred by the Primary Health Care (PHC) staff.The level of awareness on OPMD and its risk factors were very low. Incidental findings during the dental screening being the main mode of detection of OPMD, highlights the importance of conducting opportunistic screening at dental settings. Implementation of the Risk Factor Model (RFM) approach for the early detection of oral cancer through PHC staff and GMP is validated to encourage more early referrals.

A multi-centre survey reveals variations in the standard treatments and treatment modifications for head and neck cancer patients during Covid-19 pandemic

BackgroundThe onset of the COVID-19 pandemic necessitated rapid changes to the practice of head and neck oncology in UK. There was a delay between the onset of the pandemic and the release of guidelines from cancer societies and networks, leading to a variable response of individual centres. This survey was conducted to assess the pre-Covid-19 pandemic standard of practice for head and neck oncology patients and the treatment modifications introduced during the first wave of the pandemic in UK. MethodologyThe UK National Cancer Research Institute (NCRI) Head and Neck Clinical Studies Group initiated a multi-centre survey using questionnaire to investigate the effect on feeding tube practice, radiotherapy (RT) fractionation and volumes, use of chemotherapy in the neo-adjuvant, concurrent and palliative setting, the use of immunotherapy in the palliative setting, access to radiology and histopathology services, and availability of surgical procedures. Results30 centres were approached across UK; 23 (76.7%) centres responded and were included in the survey. There were differences in the standard practices in feeding tube policy, RT dose and fractionation as well as concurrent chemotherapy use. 21 (91%) participating centres had at least one treatment modification. 15 (65%) centres initiated a change in radical RT; changing to either a hypofractionation or acceleration schedule. For post-operative RT 10 centres (43.5%) changed to a hypofractionation schedule. 12 (52.2%) centres stopped neo-adjuvant chemotherapy for all patients; 13 (56.5%) centres followed selective omission of chemotherapy in concurrent chemo-radiotherapy patients, 17 (73.9%) centres changed first-line chemotherapy treatment to pembrolizumab (following NHS England’s interim guidance) and 8 (34.8%) centres stopped the treatment early or offered delays for patients that have been already on systemic treatment. The majority of centres did not have significant changes associated with surgery, radiology, histopathology and dental screening. ConclusionThere are variations in the standard of practice and treatment modifications for head and neck cancer patients during Covid-19 pandemic. A timely initiative is required to form a consensus on head and neck cancer management in the UK and other countries.

Training dental hygienists to place interim therapeutic restorations in a school‐based teledentistry program: Oregon's virtual dental home

The objectives of this study on Oregon's virtual dental home were to: 1) demonstrate the feasibility of pilot project training of existing Expanded Practice Dental Hygienists (EPDHs) to perform interim therapeutic restorations (ITRs) in the community settings after diagnosis by the supervising dentist via teledentistry and 2) evaluate satisfaction of parents/guardians of children participating in a pilot program that provides school-based/on-site preventive dental care services utilizing expanded scope EPDHs to conduct dental screenings and place ITRs. This demonstration project was a 4-years longitudinal cohort study (2016-2019) in the school/community-based settings focusing on children in kindergarten to 3rd grade. EPDHs and dentists from a Dental Care Organization were trained to utilize teledentistry and EPDHs were trained to place ITRs, the latter provided onsite dental care. Data was collected regarding child's demographics and oral health status; and parents reported level of satisfaction from services received by their children. Data analysis included descriptive statistics and logistic regression analysis to assess the relative importance of demographic and clinical factors on caries status. Onsite dental care was provided to 759 children. Of repeat patients (n = 377), 201 (53.3%) children had untreated decay at their first visit. Of these, 13% saw improvements in oral health status at their most recent visit (MRV). There were 162 ITRs planned out of which 50 patients received 99 ITRs. No adverse events were experienced. Of the repeat children receiving ITRs (n = 43), 28% saw improvement in their caries status at their MRV. Parents reported very high levels of satisfaction with the dental care program. Oregon's virtual dental home project was successful in training EPDHs to perform ITRs safely in school settings after caries diagnosis by the supervising dentist via teledentistry and in integrating this component into a regular school-based preventive dental program.

Consequences of the COVID-19 Pandemic and Governmental Containment Policies on the Detection and Therapy of Oral Malignant Lesions-A Retrospective, Multicenter Cohort Study from Germany.

Simple SummaryDue to the COVID-19 pandemic, the oncology community was challenged with the need to protect a vulnerable population from a potentially fatal infection without jeopardizing cancer treatments. The impact of the crisis on the medical care of patients with oral cancer is largely unexplored. This multicenter cohort study from Germany aims to assess the consequences of the COVID-19 pandemic by comparing the healthcare of patients during the lockdown and post-lockdown periods in 2020 with the corresponding periods in 2018/19. We found the closure of dental practices during lockdown to possibly delay the diagnosis of oral cancer. Even if during this period no higher incidence of oral cancer was observed, data point to potentially fatal consequences for longer periods of treatment delay.(1) Background: In response to the global COVID-19 pandemic, governmental measures have been undertaken. The impact of the crisis on the healthcare of patients with cancer is largely unexplored. This multicenter cohort study aimed to investigate a potential screening delay and its consequences in patients with oral cancer (OC) during the pandemic. (2) Material and Methods: Data of patients who were first diagnosed with OC during different periods were collected, especially in terms of OC incidence, tumor stage/entity and time to intervention. The periods lockdown (LD) (13 March–16 June 2020), post-lockdown (PLD) (17 June–1 November 2020), and the corresponding equivalents in 2018/19 were differentiated and compared. (3) Results: There was no obvious trend towards a higher incidence of OC or higher tumor stages, whereas a trend towards a shorter time to intervention during the LD2020 could be observed. Subgroup analyses revealed an increased incidence in OC within the PLD2020 in Mainz, which might be explained by the partial closure of dental practices in this federal state during LD. (4) Conclusions: While there was no overall higher incidence of OC, we found closure of practices during LD to possibly delay cancer diagnosis. Therefore, measures must be taken to identify patients at risk and to ensure basic healthcare, especially in the context of dental screening measures.
