  • Oral Care for Children with Leukaemia
    Oral care in children with leukaemia Oral care for children with leukaemia SY Cho, AC Cheng, MCK Cheng Objectives. To review the oral care regimens for children with acute leukaemia, and to present an easy-to- follow oral care protocol for those affected children. Data sources. Medline and non-Medline search of the literature; local data; and personal experience. Study selection. Articles containing supportive scientific evidence were selected. Data extraction. Data were extracted and reviewed independently by the authors. Data synthesis. Cancer is an uncommon disease in children, yet it is second only to accidents as a cause of death for children in many countries. Acute leukaemia is the most common type of malignancy encountered in children. The disease and its treatment can directly or indirectly affect the child’s oral health and dental development. Any existing lesions that might have normally been dormant can also flare up and become life- threatening once the child is immunosuppressed. Proper oral care before, during, and after cancer therapy has been found to be effective in preventing and controlling such oral complications. Conclusion. Proper oral care for children with leukaemia is critical. Long-term follow-up of these children is also necessary to monitor their dental and orofacial growth.

  • A Qualitative and Comprehensive Analysis of Caries Susceptibility for Dental Fluorosis Patients

Previous studies mainly focused on the acid resistance of fluorotic enamel and failed to reach a consensus on the topic of the caries susceptibility of DF patients. In this review, we discuss the role of DF classification in assessing this susceptibility and follow the “four factors theory” in weighing the pros and cons of DF classification in terms of host factor (dental enamel and saliva), food factor, bacteria factor, and DF treatment factor. From our analysis, we find that susceptibility is possibly determined by various factors such as the extent of structural and chemical changes in fluorotic enamel, eating habits, fluoride levels in diets and in the oral cavity, changes in quantity and quality of saliva, and/or oral hygiene. Thus, a universal conclusion regarding caries susceptibility might not exist, instead depending on each individual’s situation.

  • Full Mouth Rehabilitation in a Medically Compromised Patient with Fluorosis D Entistry S Ection
    Case Report DOI: 10.7860/JCDR/2014/9148.4594 Full Mouth Rehabilitation in a Medically ection Compromised Patient with Fluorosis S entistry D RAMTA BANSAL1, ADITYA JAIN2, SUNANDAN MITTAL3, TARUN KUMAR4 ABSTRACT Severely worn out dentition needs to be given definite attention as it not only affects aesthetics but can also cause psychological distress to the affected individual. It can cause chewing difficulty, temporomandibular joint problems, headaches, pain and facial collapse. Before any attempt to restore severely worn dentition, aetiology of excessive tooth wear should be established. Severe wear can result from chemical cause, mechanical cause or a combination of various causes. Dental fluorosis can also result in severe wear of teeth. Teeth sometimes become extremely porous and friable with a mottled appearance ranging from yellow to brown-black. There occurs loss of tooth substance and anatomic dental deformities resulting in un-aesthetic dentition requiring full mouth rehabilitation. Here a similar case of full mouth rehabilitation of severely worn dentition due to dental fluorosis in a 27-year-old patient is presented. This case report conjointly presents the uncommon association of diabetes insipidus with dental fluorosis. Diabetes insipidus through its characteristic symptom of polydipsia can result in intake of more than permitted dose of fluoride thus causing dental fluorosis. In literature only few cases have been reported of dental fluorosis in association of diabetes insipidus. Full mouth rehabilitation of the patient was successfully accomplished through well-planned systematic approach to simultaneously fulfill aesthetic, occlusal and functional parameters. Keywords: Dental fluorosis, Diabetes insipidus, Rehabilitation, Tooth wear, Vertical dimension of occlusion CASE REPORT history of excessive fluoride intake related to diabetes insipidus.

Beltagy*, Enas A. El-Gendy**, Emad F. Essa*** and Ibrahim A. Kabbash**** ABSTRACT Background: The prevalence studies on common pediatric oral lesions (POLs) are still rare compared with those on dental caries and periodontal diseases. POLs vary among different geographic regions, age, racial and lifestyle of each population. The purpose of this study was to determine the most common 5 POLs referred to 5 different dental and medical branches in Middle Nile Delta, Egypt. Materials and methods: A qualitative study design was used depending on expert opinions on oral lesions in children (aged 0-14 years). A total of 1164 dental and medical staff members, dentists and physicians at the hospitals of Universities and Ministry of Health, and Specialized Medical Centers & hospitals in the Middle Nile Delta region were included. The target population of the study was experts in 5 branches: Pedodontics, Oral Medicine and Periodontology, Oral and Maxillofacial Surgery, Pediatrics, and Dermatology and Venereology. Data were collected using a checklist including the common diseases within the scope of the study and each expert was asked to give percentages for children seen with each disease entity in his/her branch. Data analysis: Data were statistically analyzed using Statistical Package for the Social Sciences version 19. For each disease, the number and percentage were calculated and differences between observation recorded by health care workers in University and Ministry of Health were tested by chi-square test.

  • Policy and Practice
    Policy and Practice Theme Papers The global burden of oral diseases and risks to oral health Poul Erik Petersen,1 Denis Bourgeois,1 Hiroshi Ogawa,1 Saskia Estupinan-Day,2 & Charlotte Ndiaye3 Abstract This paper outlines the burden of oral diseases worldwide and describes the influence of major sociobehavioural risk factors in oral health. Despite great improvements in the oral health of populations in several countries, global problems still persist. The burden of oral disease is particularly high for the disadvantaged and poor population groups in both developing and developed countries. Oral diseases such as dental caries, periodontal disease, tooth loss, oral mucosal lesions and oropharyngeal cancers, human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)-related oral disease and orodental trauma are major public health problems worldwide and poor oral health has a profound effect on general health and quality of life. The diversity in oral disease patterns and development trends across countries and regions reflects distinct risk profiles and the establishment of preventive oral health care programmes. The important role of sociobehavioural and environmental factors in oral health and disease has been shown in a large number of socioepidemiological surveys. In addition to poor living conditions, the major risk factors relate to unhealthy lifestyles (i.e. poor diet, nutrition and oral hygiene and use of tobacco and alcohol), and limited availability and accessibility of oral health services. Several oral diseases are linked to noncommunicable chronic diseases primarily because of common risk factors. Moreover, general diseases often have oral manifestations (e.g. diabetes or HIV/AIDS). Worldwide strengthening of public health programmes through the implementation of effective measures for the prevention of oral disease and promotion of oral health is urgently needed.

There are also other deficiencies which may occur in a large number of people. Some may cause irreversible changes in the body while others may not cause irreversible complications. Yet, these can interfere with the normal functions of the body. Some vitamin deficiencies are important examples. In this unit, we will discuss vitamin deficiencies like ariboflavinosis, beriberi, scurvy. You will also learn about fluorosis and lathyrism. The latter two diseases are not deficiency diseases. Lathyrism is caused by a toxin present in a foodstuff. On the other hand, fluorosis occurs because of excessive consumption of fluoride in water and foods. Objectives After studying this unit, you will be able to : describe vitamin deficiencies like ariboflavinosis, beriberi, scurvy, rickets and pellagra discuss the major features of fluorosis and lathyrism caused by consumption of excessive amounts of a nutrient (fluoride) or a toxin and enumerate the measures taken to treat and prevent, these disorders.

Nutter, D.A. Honors Director _______________________________ Date ORAL HEALTH IN AFRICA 3 Abstract The African continent has continuously suffered from poverty, poor sanitation, and malnutrition, leaving it an open feeding ground for infectious disease and premature death. Along with poor oral hygiene and an unavailability of dental clinics, oral disease is allowed to thrive and cause great harm. In the last two decades, the World Health Organization and others have tried to implement better systems of oral health care for the African people and have advocated for more well-trained dentists, dental clinics, equipment, and affordable dental care. Progress has been made in some African countries, but the continent is still in serious need of an oral health care system that will deliver quality, affordable dental care, with equal access for all people. ORAL HEALTH IN AFRICA 4 The State of Oral Health on the African Continent The field of dentistry has seen great advancements in recent years. From invisible braces to teeth whitening, new types of fluoride treatments to electronic toothbrushes, dentistry in America is quickly advancing and offering novel and exciting treatments and products for the middle class consumer.
