Item What should I do when I suspect a child patient is being abused?(South African Dental Association, 2010) Naidoo, SudeshniThe warning signs of abuse should be considered every time an injured patient is seen. Repeated injuries, multiple bruises, or injuries with uncertain explanations may signal instances of abuse.Item Dental ethics case 2: What are your responsibilities to patients who may have an eating disorder?(South African Dental Association, 2010) Naidoo, SudeshniEating disorders are a serious concern and can also have significant consequences on oral health. They represent a clinical challenge to dental professionals because of their unique psychological, medical, nutritional and dental patterns as well as their distinctive characteristics.Item Dental ethics case 3: informed consent: risks and benefits of treatment(South African Dental Association, 2010) Naidoo, SudeshniStudies have shown that pre-operative patient education, providing coping strategies and/or reasonable expectations regarding the post-operative course can help lessen patient anxiety and decrease pain, complications and recovery time.Item Perceptions of intimidation and bullying in dental schools: a multi-national study(Wiley, 2010) Rowland, Michael; Naidoo, Sudeshni; AbdulKadir, Rahimah; Moraru, Ruxandra; Huang, Boyen; Pau, AllanObjectives: To determine first year dental students' perceptions of intimidation by instructors and bullying by fellow students. Methods: Data were collected through a cross-sectional survey of first year dental students from seven dental schools representing five countries; one each from Romania, South Africa, Australia and the USA, and three from Malaysia. Self-report questionnaires were administered to participants at least six months after they had commenced their dental degree course during 2005–6. Results: Over a third (34.6%) reported that they had been intimidated or badly treated by their tutors/instructors and 17% reported that they had been bullied or badly treated by their fellow students in the recent past. There were statistically significant differences in reports of intimidation by instructors between the different dental schools. Intimidation by instructors was associated with a history of medication use for stress, anxiety and depression, and perceived stress in the past month. There were no statistically significant variations in reports of bullying by fellow students between different dental schools. Bullying by fellow students was associated with dieting to lose weight, self-reported general health and perceived stress. Conclusions: This multi-national study highlights that intimidation and bullying is prevalent within dental teaching and training environments. Future research is needed to explore their impact on students' well-being and academic progress as well as on patient care. Clinical Implications: Dentists are the best recruiters for the profession. If the dental school experience is a negative one it can have significant impact on the future of the profession.Item Why dentists should take a greater interest in sex and gender(Nature Publishing Group, 2010) Doyal, Lesley; Naidoo, SudeshniThis brief review highlights the lack of evidence relating to sex and gender differences in oral health as well as the widespread conceptual confusion and conflation that often underlies them. A broader biomedical understanding of these issues will offer a valuable framework within which differences in oral health between women and men can be further explored. This in turn would facilitate the development of the evidence base necessary to optimise the efficacy of dental practice in meeting the needs of both women and men patients.Item Dental ethics case 17: What are my obligations and ethical responsibilities when treating patients with HIV?(South African Dental Association, 2011) Naidoo, SudeshniThis ethical case is about a 20 year old female patient who had recurrent ulcers in and around her mouth. The dentist suspected that the recurrent ulcers and candidiasis were oral manifestations of HIV and confronted her with his suspicions of her being HIV-positive.Item Dental ethics case 16: Pull out my four front teeth ...(South African Dental Association, 2011) Naidoo, SudeshniThe scenario is a 14 year old girl who requests the extraction of her four front teeth, even though she has no problems with her teeth. She said it is because all her friends and some of her family members have had their front teeth extracted and she would like to do the same. Despite counselling against the removal of her teeth, she is adamant that she wants the teeth removed. A commentary is given on this scenario.Item Dental ethics case 13: what do I do when I suspect that my elderly patient is being abused?: dental ethics(South African Dental Association, 2011) Naidoo, SudeshniThe problem of elder abuse and neglect in South Africa is widespread. Elder abuse occurs across all economic, ethnic, religious, gender and cultural groups. In South Africa the problem was previously the sole responsibility of the Department of Welfare (Social Development) with the result that abuse was only dealt with in homes for the aged. With older persons encouraged to live in their communities and families as long as possible, it means that the responsibility for dealing with elder abuse has shifted to many more sectors. Elder abuse can be defined as “a single, or repeated act, or lack of appropriate action, occurring within any relationship where there is an expectation of trust which causes harm or distress to an older person”. Elder abuse can take various forms such as physical, psychological or emotional, sexual and financial abuse. It can also be the result of intentional or unintentional neglect.Item Dental ethics case 21: extreme makeovers - the ethics of aesthetic dentistry(South African Dental Association, 2012) Naidoo, SudeshniAesthetic sensibilities need to develop within the limits of physiological, morphological and occlusal parameters in restoring function and improving dentofacial and facial aesthetics.Item Dental ethics case 20 suspected malignancy: to tell or not to tell the truth?(South African Dental Association, 2012) Naidoo, SudeshniItem Dental ethics case 24: Non-therapeutic cosmetic treatments including botox(South African Dental Association, 2012) Naidoo, SudeshniItem Dental ethics case 27 - the orthodontic dilemma of non-compliance(South African Dental Association, 2012) Naidoo, SudeshniItem Academic-service partnerships, research, and the South African Dental Academic(American Dental Education Association, 2012) Grossman, Elly S.; Naidoo, SudeshniIn South Africa, academic dentistry is managed through joint agreements between the South African Department of Health (DoH) and each university, in a type of academic-service partnership. For this study, dental faculty members were surveyed to ascertain staff attitudes towards academic research in dental schools and to find out whether the joint arrangement impinges upon research activities. A survey was distributed to 200 members of the South African division of the International Association for Dental Research (SA IADR) and the academic staff of the four South African dental schools. One hundred and five responses were obtained for a response rate of 53 percent; most of the respondents were lecturers (26 percent), specialists (17 percent), heads of department (17 percent), or senior lecturers (13 percent). The majority were employed by the DoH (77 percent) and were members of the SA IADR (51 percent). Most reported feeling that research is an important issue in their school (83 percent) and perceived general research output had declined (59 percent). While 79 percent said they were concerned about the decline, many (71 percent) felt there was little they could do about it. The respondents mentioned the following as reasons for the decline: lackluster approach of DoH structures, weak university support, poor research equipment and facilities, inadequate funding, emphasis on service delivery, undergraduate teaching loads, onerous working conditions, and lack of vision, leadership, and governance by senior management. Faculty members’ twin obligations of service delivery (required by the DoH) and teaching (required by their institutions) have severely impacted South African academic dental research.Item Dental ethics case 25 the drug-abusing patient – what are my ethical obligations to treat?(South African Dental Association, 2012) Naidoo, SudeshniItem Dental ethics case 18: Use of amalgam for dental restorations(South African Dental Association, 2012) Naidoo, SudeshniA commentary is given to the scenario of patients who request that the removal of perfectly serviceable amalgam restorations and replace them with composite or tooth-coloured materials.Item Dental ethics case 26 the incompetent geriatric patient(South African Dental Association, 2012) Naidoo, SudeshniItem Cytotoxicity of seven recent dentine bonding agents on mouse 3T3 fibroblast cells(Scientific Research Publishing, 2012) Olivier, Annette; Grobler, Sias Renier; Osman, Yusuf IsmailToday it is generally accepted that most bonding agents are cytotoxic. In this study the relative cyto-toxicity of seven recent dentine bonding agents on mouse 3T3 fibroblast cells were investigated. Materials and Methods. Near-confluent mouse 3T3 fibro- blast cells were exposed to Dulbecco Modified Eagle’s Medium containing extractions from the seven different bonding agents. The cell survival rate was then determined using the standard MTT assay. Results. The cell survival rate ranking is: iBond (94%) < Gbond (78%) < Xeno V (71%) < Adper Easy Bond (63%) < Xeno V+ (61%) < Adper Scotchbond SE (33%) < XP Bond (32%). Part A of Adper Scotchbond SE had a survival rate of 35% and part B 38%. These two parts did not differ significantly. Adper Scotchbond SE and XP Bond do not differ significantly. While Xeno V+, Xeno V and Adper Easy Bond do not differ. (p < 5%; Tukey-Kramer Multiple-Comparison Test). Conclusion. All of the tested adhesive bonding agents were cytotoxic with survival rate of 3T3 cells between 94% to 31%. Of the 7 bonding agents tested iBond was found to be only slightly toxic and by far the least toxic. The two bonding agents (XP Bond and Adper Scotchbond SE) containing UDMA plus TEGDMA plus HEMA plus camphorquinone were found to be the most toxic.Item Patient’s access to records(South African Dental Association, 2013) Naidoo, SudeshniA long-standing patient in an established practice requests her dental records and x-rays from the practice receptionist. She was last seen three years ago. Despite an intensive search, the receptionist is unable to locate the file. The patient says that she is entitled by law to have access to her records at any time. The receptionist then informs her that her record might have been destroyed the previous year, since she had not been to the practice for a long time.Item How do I comment ethically on the work of colleagues?(South African Dental Association, 2013) Naidoo, SudeshniItem Practitioners enrolling their patients in clinical research(South African Dental Association, 2013) Naidoo, Sudeshni
