Abstract:

Presently, cancer one of the most prevalent types of disease is a growing health problem around the world and is one of the leading causes of death. Oral cancer is the sixth most common cancer which occurs worldwide and continues to be the most prevalent cancer which develops in multistep process from pre-existing potentially malignant lesions. The most common precancer is leukoplakia which represents 85% of such lesions and 95% of oral cancers are squamous cell carcinomas (OSCC). In India, the incidence of oral submucous fibrosis (OSMF) and OSCC is also increasing like an epidemic and vast majority of OSCC arises from pre-existing leukoplakia. Several studies have reported that 1-18% of premalignant oral lesions will develop into malignant form. C. albicans has also been identified as a possible factor in development of oral leukoplakia and its malignant transformation. Candida species, dimorphic harmless eukaryotic organism are members of phylum Ascomycota. In healthy individuals, it mostly resides as a part of normal commensal microbial flora on mucosal surfaces of oral cavity. C. albicans grows as a filamentous form, capable of forming true hyphae and is one of the only Candida species. Hyphae play important roles in adhesion and invasion into epithelium. It contributes many virulence attributes like adherence to host tissue and release of some hydrolytic enzymes. It is still unclear, how an increased amount of C. albicans in oral cavity influence the progression of pre-cancer to malignancy. A higher level of C. albicans is present in precancerous and OSCC patients. C. albicans is most pathogenic and significantly more successful pathogen in oral malignancy transformation. There are no drugs which can effect extremely to treat oral cancers. There is a general call for new emerging drugs that are highly effective towards cancer, possess low toxicity, and have a minor environment impact. Novel natural products offer opportunities for innovation in drug discovery. Natural compounds isolated from medicinal plants, as rich sources of novel anticancer drugs, have been of increasing interest. The alarming reports of cancer cases increase the awareness amongst the clinicians and researchers pertaining to investigate newer drug with low toxicity.

Mridula Goswami is Professor & Head, Dept. of Pedodontics & Preventive Dentistry, Maulana Azad Institute of Dental Sciences, New Delhi, India. She has her passion in being with children and expertise in Paediatric Dentistry practice since last 18 years. She is involved in teaching undergraduate and postgraduate courses. Her academic career has many medals & awards. She has to her credit the “Fellowship of International College of Dentists”. Now she is involved in research of her current interest topics which are regenerative endodontics, trauma in children, special need children and lasers in pediatric dentistry.

Abstract:

Statement of the Problem: Pulpal necrosis in an immature tooth with an open apex can have devastating consequences for paediatric dental patients and presents a distinctive challenge for the dentists. Earlier clinicians relied on traditional apexification procedures or the use of apical barriers to treat immature teeth with pulpal necrosis. The latest treatment modalities consist of regeneration-based approaches of tissue engineering.

Theoretical Orientation & Method: Regenerative endodontics is a promising development in the field of tissue engineering involving the diseased or necrotic pulp to be removed and attempted to be replaced with healthy pulp in order to revitalize the teeth. The concept involved in the procedures based on regenerative endodontics is that the platelets in the blood play an important role in hemostasis and wound healing. Dental stem cells and the pulpal connective tissue play a major role in these techniques. Periapical tissues around immature teeth have a rich blood supply and contain stem cells that have relative potential to regenerate in response to tissue injury. This presentation describes two Regenerative Endodontic Techniques i.e. Revascularization procedure and technique using platelet-rich fibrin (PRF). Through clinical case results, it describes the current concepts, treatment approaches and recent developments in the field of ‘Regenerative Endodontics’.

Results: Treatment aims to allow continuation of root development and to regenerate the pulp inside the damaged tooth, preventing the need for routine endodontic treatment. Series of clinical case outcomes show healing of apical periodontitis, promotion of continued root development and restoration of the functional competence of pulpal tissue.

Conclusion & Significance: Continued research, knowledge and understanding can aid in handling scientific challenges of regenerating dental tissues and validating the success of these procedures as an alternative to apexification. With focused research, regeneration of pulp/dentine is likely to be a predictable clinical procedure than a mere vision.

Biography:

 I’m a Kuwaiti dentist, born in Kuwait in 1979. I got my BDS from Cairo University, Egypt in 2001. Since 2001 I’m appointed by the Ministry of Health- Kuwait. In 2002, I worked at the School Oral Health Program as a general pediatric dentist. I participated in a survey in 2004 as an examiner for oral screening of school children. From 2006 to 2016 worked as the Oral Health Education and Prevention team leader. I got MFDS from the RCSI in 2011 and in 2014 Kuwait Board Dental Program Part I. Currently; I’m the Head of Al-Jahra School Oral Health Program.

Abstract:

Objective: The aim of this study was to assess the oral health related quality of life of adults in Kuwait.

Method: A cross- sectional study was done among adults during oral health education activities done by Capital School Oral Program 2012. Self-reported questionnaire was distributed. A convenience sample (N=503) participated in this study. The questionnaire had six sections. One section was about the OHRQoL that consisted of nine questions.

Result: The mean age of participated adults was 35.1±11.08. Females were 43% and 52% were males. Most of participants were healthy. Sixty three percent of participants have college or higher than college level of education. Approximately, quarter of participants (71%) were married with the mean number of children was 3.4±1.6. The OHRQoL measurements showed that 95% of participants enjoyed eating and they liked their smile (80%). Only, 3% had speech difficulties. More than half of participants reported that they never had any social disabilities related to their oral health (62.5%). Most of participants mentioned that they never had any psychosocial disabilities regarding their oral health (79.5%). Overall, 79% of participants judged their oral health as excellent, very good, or good. Seventy nine percent of participants were satisfied about their oral health.

Conclusion: OHRQoL of adults in Kuwait was satisfactory in functional and psychosocial factors related to oral health. Results also indicate that some participants had social disabilities. This can be attributed to high levels of oral diseases among them. National oral health survey among adults should be done to establish this relationship.

Abstract:

Objectives: Leukocyte and Platelet-Rich Fibrin (L-PRF) is a 3-D autogenous biomaterial obtained via the simple and rapid centrifugation of whole blood patient samples, in the absence of anti-coagulants, bovine thrombin, additives or any gelifying agents. A relatively new “revolutionary” step in second generation platelet concentrate-based therapeutics, the clinical safety more so, efficacy and effectiveness of L-PRF remains highly-debatable, whether due to preparation protocol variabilities, limited evidence-based scientific and clinical literature and/or inadequate understanding of its bio-components. This critical review provides an update on the application and clinical potential/effectiveness of L-PRF during oral surgery procedures, limited to evidence obtained from human Randomized and Controlled Clinical Trials. Recent functional recommendations on L-PRF preparation protocols are provided to the interested clinician as well as the involved researcher.

Data: All available/accessible clinical trials.

Sources: PubMed (from Jan 2014 – Feb 2016).

Study Selection: Eligibility criteria included: “Human Randomized Controlled Clinical Trials” and “Use of Choukroun’s classic L-PRF preparations only”.

Conclusions: Autologous L-PRF is often associated with early bone formation and maturation; accelerated soft-tissue healing; and reduced post-surgical pain, edema and discomfort. Preparation protocols require revision and standardization. Well-designed RCTs (according to the CONSORT statement) are also needed for validation. Furthermore, a better analysis of rheological properties, bio-components and bioactive function of L-PRF preparations would enhance the cogency, comprehension and therapeutic potential of the reported findings or “observations”; a step closer towards a new era of “super” dental bio-materials and -scaffolds.

Clinical Significance: L-PRF is a simple, malleable and safe biomaterial suitable for use in oral surgery. An innovative tool in Regenerative Dentistry, L-PRF seems a robust and possibly a cost-effective biomaterial alternate for oro-dental tissue repair and regeneration.

He is an Associate Professor at National Yang-Ming University, and the Director of Education and Research Department of Taipei City Hospital, Taiwan. He has published more than 50 papers in reputed journals and has been serving as an Editorial Board Member of Journal of Dental Sciences and other reputated professional journals.    

Abstract:

Background & Purpose: According to the results of 2012 national survey in Taiwan, the mean DMFT among 12-year-old school children was 2.50, indicating a significant potential of improvement to be made.

Materials & Method: We used structured questionnaires and standardized oral health check for selected school children to investigate potential risk factors of dental caries, including: caries prevalence, use of fluoride and other prevention measures, caries experience, daily consumption of sugar sweetened food, knowledge and attitude of oral health of main carers, influence of peers, periodic oral health check and self care.

Results: 1856 selected school children of grade 2 and 3 took part in the oral health check, and their parents completed the questionnaires. 965 (51.99%) were boys, mean and SD of age were 8.19 and 0.71 respectively. Those of deft were 4.10±3.21; DMFT 0.90±1.40. The prevalence of caries experience in primary dentition was 82.70%, and permanent dentition 40.84%. Most (1222, 65.84%) of the questionnaires were answered by mothers. 43% of the carers agreed that “water fluoridation is a safe, economic, and effective measure to prevent dental caries”. Similarly, 72% agreed that “fluoride toothpaste is a safe, economic, and effective measure to prevent dental caries”. Multiple regression analysis showed that factors associated with deft of school children were: Gender, age, father’s education, have sugar sweetened drinks, the degree of sweetness of the drinks, and fond of sweets.

Discussion & Suggestions: Our study results showed that most parents had a good understanding for topical fluoridation, and the negative influence of sweets to dental caries. However, only 37% of children used fluoridated toothpaste. There is a gap between what people know and what they do for their children’s oral health. The government, the dental society, and the parents need to take more actions to promote children’s oral health.

Abstract:

Introduction: Age estimation is determination of person’s age by using various methods of age estimation for adult and children. The age estimation by using teeth is widely used by many methods and of these methods is the Demirjian method which firstly was introduced in 1973 and used to estimate the age in children.

Aim: The aim of the study was to test the Demirjian method of dental age estimation in Sudanese children population aged (3-16 years).

Methodology: The study design was descriptive retrospective cross sectional hospital based study. The sample was selected using a simple random sampling technique consisting of 500 orthopantograms, (243 boys and 257 girls) collected from Dental Hospital of University of Science and Technology, Esthetica, Almazin and Salah Dafallh’s dental centers. The developmental stages were assessed for each OPG in the left seven mandible permanent teeth and the EA was obtained using Demerjian method and then compared with the chronological age.

Result: The results showed that Demirjian method was not applicable on Sudanese population. It overestimated the age of female samples by about (0.13) years, and under estimated the age of male samples by about (0.46) years. Demirjian method was more reliable in females than males.

Conclusions: Generally Demirjian method was more applicable in females than males and it was more reliable to females in the age group of 15–16 years.

Abstract:

Background

Breakfast cereals remain popular with children and although they are mainly eaten at breakfast time they are regularly eaten between meals because they are quick and easy to prepare. In the UK breakfast cereals are promoted using a wide variety of marketing techniques via a range of media (e.g. TV, radio, magazines, social media) concepts such as the “healthy breakfast option” and a good way to start the day or “fuel your day” predominate. However, many breakfast cereals contain high levels of sugar, some reaching 35% or more. Regular consumption of high sugar breakfast cereals is of concern both from a dental and a general health perspective because of the relationship with dental caries and excess energy intake which could potentially lead to obesity and/or diabetes.

Aim/Objectives: The aim of this study was to ascertain how breakfast cereals in the UK are specifically marketed to children in terms of the nutritional messages portrayed, especially in terms of oral health, both via the written word and visual images. 

Methods: 13 of the most popular UK children’s breakfast cereals, including branded and supermarket own-brand versions, were selected for this study. A content analysis was performed using the packaging of each breakfast cereal type; which involved a detailed analysis of the imagery and claims made, together with an assessment of the nutritional content.  An additional case study of the most popular brand was undertaken to assess wider media advertising via the internet and social media.

Results: Four of the nine breakfast cereals contained high levels of sugar, according to the UK Traffic Light System which categorises high as in excess of 22.5%; Kellogg’s Frosties contained 37% sugar. The remaining 5 cereals had between 4.4% and 21.4%.  With regard to salt and fat, all cereals analysed were labelled as either containing low or medium levels. Supermarket own-brand versions did not differ in nutritional content when compared with the market leader. Nutritional claims focussed on vitamins especially folic acid, iron, whole grains, and no artificial colours or flavours and these were legitimate in terms of nutritional content. Only two opted for the voluntary Front of Pack traffic-light system and these were the supermarket own-brands. A range of marketing techniques were employed, e.g. cartoon characters, royal endorsements, QR codes.  The imagery surrounding portion size was grossly misleading.

Conclusion: Some breakfast cereals marketed to children in the UK have very high levels of sugar and the manufacturers use legitimate claims about other nutritional constituents to potentially mislead consumers into thinking the breakfast cereals are healthy. Furthermore, the imagery surrounding portion size is of particular concern when actual portion sizes should be at least a third less than those portrayed on food packaging.  Dental and other health professionals need to be aware of the high sugar content of these cereals and the marketing techniques employed by their manufacturers when giving nutritional advice to children and parents.

Abstract:

Abstrcat:

Oral cavity  squamous cell carcinoma (OC-SCCa) accounts for  nearly 1/3 of all head and neck squamous cell cancers in the US however with significant international geographic variation due to carcinogen exposure and availability. The mainstay of treatment for resectable disease had been surgery with postoperative radiation based on specific clinical and pathologic features.   Survival rates have little improved prior to the use of concurrent postoperative chemoradition.   Since 2009, we have employed induction chemotherapy (ICT)  as an option to be added to the comprehensive treatment of OC-SCCa. A review of our outcomes was conducted.

Patients/Methods:  Retrospective review from 2010 -2015 of  patients with stage IV OC-SCCa with minimal 24 month follow-up who received  ICT and with no previous history of treated head & neck SCCa.  59 patients were identified however 6 met inclusion criteria.  All received 2 to 3 cycles of ICT consisting of cisplatin and either fluorouracil and/or a taxane.  Following IHC, all underwent surgical resection.

Results: Survival from OC-SCCa was 100% with 4 patients NED and 2 patients DOC/NED.  Median survival was 54.3 months.  Three patients had ICT complications but recovered and proceeded to surgery.  There were 3 surgical complications in 2 patients.  Historic literature based on AJCC data has survial at 4.5 years to be approximately 29%.

Conclusions: Though the study size is small, ICT demonstrated excellent tumor response in our patient population with enduring and superior disease free survival.  A larger multicenter trial would be required to confirm these results and outline chemotherapy drug selection.
