Day 1 :
Dental core Training at Kings college Hospital, UK
Keynote: Catastrophizing, pain self-efficacy and acceptance in patients with Burning Mouth Syndrome
Time : 09:00-09:30
Pavneet is currently completing her dental core training at King’s College Hospital in Oral Surgery. She has a keen interest in facial pain and has published multiple times in peer reviewed journals on the topic.
burning mouth syndrome (BMS) can negatively impact health-related quality of life (HRQoL) and is linked to anxiety and depressive disorders. Less is known about pain-related cognitions in BMS and how they affect mood and health.
Objectives: To describe pain catastrophising, pain self-efficacy and chronic pain acceptance in BMS patients and explore associations with affective function and HRQoL.
Methods: A cross-sectional study of 36 BMS patients (31 female) referred to an Orofacial Pain Clinic completed the Pain Catastrophizing Scale, the Pain Self-Efficacy Questionnaire and the Chronic Pain Acceptance Questionnaire-8 in addition to standardised self-reported questionnaires measuring mood and oral and generic HRQoL.
Results: Pain catastrophising levels were markedly higher than (nonclinical) population norms, with 32.0% of patients reporting clinically relevant levels. Pain self-efficacy and chronic pain acceptance varied widely; 24.0% evidenced low confidence to cope with pain and 53.8% reported low activity engagement and/or low pain willingness. Catastrophising showed moderate-to-strong associations with measures of anxiety (r=0.63), depression (r=0.80), and oral (r=0.61) and generic HRQoL (rho=-0.84). Self-efficacy and acceptance were also closely related to levels of depression (r/rho=-0.83 to -0.73) and generic HRQoL (r/rho=0.74 to 0.75). These associations were stronger than those between pain severity and affective function/HRQoL and persisted after controlling for pain severity.
Conclusions: A significant number of BMS patients evidence maladaptive pain-related cognitive responses, which is closely related to affective disorders and impaired HRQoL. As such, treatment approaches targeting catastrophising, pain self-efficacy and acceptance may prove beneficial in improving mood and quality of life in BMS patients
dental hygienist at Stamitoles Dental Center, USA
Keynote: Review of the Importance of Aerosol Reduction and Proper Infection Control
Time : 09:30-10:00
Ella Peskova has obtained her dental degree at Belgorod State National Research University, Russia, completed her PhD at the age of 28 years from First Moscow State Medical University, Russia, and got Associate Degree in Science in Dental Hygiene at Pensacola State College, USA. She is certified registered dental hygienist at Stamitoles Dental Center, USA. She has published more than 15 papers in reputed journals and 2 monographies. She is a member of American Dental Hygienist Assosiation.
The goal of this article to educate dentists, hygienists, and assistants on the importance of aerosol reduction and proper infection control.
While treating the patients with ultrasonic or high-speed handpiece, aerosols and spray are formed. Aerosols can remain airborne for extended periods of time and may be inhaled. Aerosols consist of particles less than 10 microns in diameter and are not typically visible to the naked eye. About 95% of aerosols are 5 micrometers or less. Most aerosols lie within 1m in front of the patient.
A high-volume evacuator (HVE) is a suction device that draws a large volume of air over a period of time. This differs from a low-volume evacuator (LVE), which pulls a significantly lower volume of air. HVE devices typically have large, single-bore or multiple openings, whereas LVE devices have a much smaller bore size. HVE remove 90-98% of aerosols regardless of source. An HVE device (left), a saliva ejector (center), and an HV evacuation mirror (right) are used to draw up the salt particles at the same speed (pic.1). Note the differences in the widthoftheirpaths. Safety precautions/infection control measures (during any hand piece, ultrasonic, or polishing).
Risk of exposure is significantly higher for dentists and hygienists using powered instrumentation such as ultrasonic and air polishers. Bacteria and viruses can spread rapidly through splatter and aerosols produced by these types of treatments. Aerosol particles can linger in the operatory for an hour or more while splatter lands on the surfaces immediately surrounding the treatment area. This poses a risk for the spread of the common cold and influenza viruses, herpes viruses, pathogenic streptococci or staphylococci, severe acute respiratory syndrome (SARS), and tuberculosis (TB).
As there is no single solution that will provide complete protection, a combination of personal protective equipment (PPE), preprocedural rinses, prepolishing, an advanced air filtration system, and an HVE offers the most effective and practical method of reducing the overall risk of infection.
The dental office required that clinicians use PPE, such as masks, gloves, eye protection, and proper lab coats; however, the office did not require a HVE as recommended in the CDC guidelines as a part of its safety protocol for working with powered instruments. Saliva ejectors and isolation devices offer no safety protection from contaminated aerosols.Additional Precautions. Change masks every 20 min in high aerosol environment, every patient, or every hour. Mask levels include 1-3: the higher the mask level, the more protectionAgainst aerosols, more filtration but less breathable
director of department of dental public health
Keynote: Association and socioeconomic status and caries among Chinese preschool children: A cross-sectional national study
Time : 10:00-10:30
Xiaojuan Zeng has completed her PhD at the age of 45 years from University College London. He is the director of department of dental public health. He has published more than 37 papers in dental public health and science of dentistry.
Objectives: To assess the association between child caries status and socioeconomic status (SES) in China. Methods: Data from the 4th National Oral Health Survey of China, which was done in 2015. The sampling process was conducted by a multistage stratified cluster method, comprising of 40,360 children aged 3-5 years. Caries indicators included untreated caries, dental pain and dmft (number of decayed, missing and filled teeth). SES was measured by parental education level and household income. The bivariate association between the participants’ characteristics and dmft was analyzed using non-parametric tests, while the untreated caries and dental pain were analyzed using Pearson’s chi-square tests. Negative binomial regression and Poisson regression models were used to analyze association between SES and oral health by regulating confounders. Results: There were significant associations between SES and all oral health indicators (p<0.05). And the trends of oral health for different SES remained significant. The prevalence of untreated caries, dental pain and dmft of children from the lowest parental education were 1.19, 1.10 and 1.19 times higher than those from the highest parental education. And the prevalence of untreated caries, dental pain and dmft of children from the lowest household income families were 1.12, 1.11 and 1.24 times higher than those from the highest household income families. Conclusions: There were consistently wide socioeconomic inequalities in child oral health in China, posing challenges for designing public health strategies and social policies.

‘Per occlusion’ in my lecture would refer to the relationship of Periodontium to Occlusion. Many questions still remain unanswered in context to relationship of occlusion to periodontal disease and vice versa. A short attempt to understand the following dilemmas:
•Whether occlusal trauma is noteworthy in the aetiology of periodontal disease?
•Whether occlusal treatment is suggested for patients suffering from periodontal disease?
• Making a correct diagnosis of trauma from occlusion.
•Tooth mobility and occlusal equilibration.
• Is splinting of teeth necessary?
•Important guidelines for good occlusal considerations in periodontics and oral Implantology.
Paulo Sergio Souza Pina
MD, PhD Student at University of São Paulo
Keynote: Clinic and histopathologic aspects of chronic hyperplastic candidiasis in oral mucosa
Time : 11:00-11:30

Candida is a dimorphic microorganism commonly found in the gastrointestinal tract, skin and mucous membranes of humans. In the yeast phase, the fungus is not pathogenic and may be present in the oral cavity of healthy individuals. Oral candidiasis is generally classified into four groups, and the hyperplastic variant is represented by a chronic infection, characterized by an epithelial hyperplasia of the host. Specifically, these lesions are difficult to differentiate from leukoplakias and they also have been associated with an increased chance of developing dysplasias and malignant lesions. The aim of this work was to analyze the incidence of chronic hyperplastic candidiasis in an Oral Pathology Service, intending to demonstrate the occurrence of these infections in the oral cavity as well as to evaluate the histology of the specimens to define the anatomopathological aspects that better characterize them. For the characterization of the samples, the clinical data of the patients and the aspects of the lesions were collected. Subsequently, the histopathological analysis of the sections was performed under light microscopy, and the hematoxylin-eosin and periodic acid Schiffer staining were used to evaluate the microscopic characteristics and the presence of Candida, respectively. The professionals who performed the biopsies were contacted to obtain information about the evolution of the lesion and the patient. In general, clinically, the lesions appeared as an asymptomatic nodule or white plaque on the tongue or buccal mucosa. Histologically, the presence of epithelial hyperplasia, exocytosis and mononuclear inflammatory infiltrate were the most noted. After contacting the professionals, some “follow-ups” were obtained

Background: The perceived need for dental care for children with special healthcare needs (CSHCN) exceeds the need for either preventive or specialty medical care.
Objective: To assess the oral health status among hospitalized and non-hospitalized children with SHCN in Riyadh, Kingdom of Saudi Arabia
Method: This case - control study assessed the oral health status in SHCN children by measuring the prevalence of DMFT, def., GI, PI, and oral lesions and relates it to hospitalization. the sample size is 300 participants aged 2-18 years old were divided into 150 hospitalized children, and 150 non-hospitalized children from several governmental and private hospitals in Riyadh. Oral examination was done after receiving consent from the legal guardians who were interviewed using the self-administered 28 item questionnaire assessing demographics, hospitalization characteristics, oral hygiene practices, dental visits, dietary behaviors, medical conditions, medication use and self-reported recurrent pathos stomatitis. Chi square test was used to compare the incidence of dental, periodontal diseases and oral lesions to hospitalization.
Results: Caries was present more in controls (non hospitalized) than cases (hospitalized). Moderate gingivitis was more prevalent in cases; however, mild gingivitis was more prevalent in controls. Plaque scores were found to be better in cases than controls, controls showed poor plaque scores.
Conclusion: The prevalence of dental caries and plaque accumulation were significantly poorer in non-hospitalized children compared to hospitalized patients. Whereas, gingival health was shown to be more deteriorated in hospitalized children in Riyadh city
Bashair Ahmed Rangoonwala
Student at Jinnah Medical and Dental College, Karachi, Pakistan
Keynote: Novel Covid-19 & it’s affect on Dental Healthcare
Time : 1:00-1:30pm
Bashair Ahmed is a 22 year old final year dental student currently enrolled in Jinnah Medical and Dental College, Karachi, Pakistan. With the ongoing pandemic which took a huge toll on everybody’s lifestyle, she used her research skills and personal hands on experience in treating dental patients to review how COVID-19, which is here to stay, has affected dental setting around the world
Novel Covid-19 has taken the world by storm with 41,104,946 confirmed cases of Covid-19, including 1,128,325 deaths as of October 22, 2020 after it was firstly reported in Wuhan, China. According to biological and clinical research, the mode of transmission of this zoonotic virus has confirmed to be through respiratory droplets which leaves the dental healthcare professionals under the high risk category of contacting the virus as dentistry involves the use of rotary dental and surgical instruments i.e. hand pieces or ultrasonic scalers which create a visible spray that can contain particle droplets of saliva, water, blood & microorganisms. Once present in the human body, SARS-CoV-2 is present abundantly in nasopharyngeal and salivary secretions of affected patients who can be either symptomatic or asymptomatic. Additionally, with basic surgical masks not being 100 percent effective against the aerosols dental practitioners were left ill-fitted to combat the virus during the initial surge when treating dental emergencies such as dent alveolar trauma and progressive facial space infection. This article, based of literature review & experience, describes how Covid-19 has brought changes in dental healthcare for both dental learning students and professionals in terms of continuing education/learning hands-on, in patient screening as the oral symptoms of Covid-19 such as xerostomia and loss of taste distinct to normal flu-like symptoms can help with diagnosis, how practice of strict infection control strategies with correct donning and doffing of PPE is now more important than before and a different approach to patient management protocol.
