The vitality of the profession rests in each succeeding crop of graduates, an injection of youthful vigour and enthusiasm which the Schools are proud to contribute to the country each year. Emerging from the rigours of the demanding dental curriculum, our new colleagues are eager to embrace the profession and to put their hard won expertise to work. That many may find it difficult to enjoy the full spectrum of treatment possibilities in Community Service is a passing problem, for the future beckons with wider options.

September, National Oral Health Month, was marked by SADA encouraging members to meet the challenge of educating their patients and members of the public about proper dental routine and conveying the message of good oral health. It is surprising - and not a little disheartening- to learn that after all these years those routines are not as thorough nor as commonplace as should be for basic and necessary oral hygiene.

There appears to be still some confusion about the difference between the professional indemnity cover and subscription rates provided by Dental Protection Limited (DPL) for state employed dentists and private practitioners in South Africa.There is also some uncertainty about exactly what members are getting for their money and what cover is provided. Private practitioners are also under a common misconception that they are somehow 'subsidising' state-employed members for most of the rates paid by state employed dentists are significantly lower than those paid by dentists working in the private sector.
The use of textural analysis to test the hardness and penetrability of three types of gutta percha cones when exposed to two endodontic solvents : researchSource: South African Dental Journal 71, pp 346 –350 (2016)More Less
Aim: Gutta-percha (GP) is removed from root canals by mechanical instrumentation used in conjunction with solvents such as Xylene and Eucalyptus oil. This study used textural analysis to test changes in the penetrability and hardness of Conventional GP, Thermafil® and Guttacore? when exposed to these solvents: rigidity was used for hardness and deformation energy and resilience for penetrability.
Methods: GP cones (n=81) were tested prior to, and following, solvent exposure. For each outcome variable, results were tabulated by group. Between-group differences were assessed employing a General Linear Model, with the outcome as the dependent variable and the solvent, GP type and solvent-GP type interaction as the independent variables.
Results: Significant differences in rigidity and deformation energy were observed. Resilience decreased in Thermafil and Guttacore, but increased in Conventional GP. A greater reduction in the hardness of Thermafil was observed with Eucalyptus oil. Conventional GP was susceptible to both solvents but penetrability decreased with Xylene. Guttacore was significantly altered by both solvents.
Conclusions: Considering the toxicity profile of Xylene, and the biocompatibility and antimicrobial effects of Eucalyptol, Eucalyptus oil is recommended for use during endodontic retreatment.

Regenerative and stem cell therapy is a new field in dentistry. The opinions of dentists and their acceptance of the concepts are important in successful clinical implementation of these procedures.
Objectives: To determine the levels of awareness, attitudes and knowledge concerning the therapeutic potential of stem cells in regenerative dentistry among dentists and to determine whether a need exists for additional training in the field.
Materials and Methods: A questionnaire on regenerative dentistry was distributed to 140 dentists in the private sector in South Africa, consisting of three broad sections: Professional status; Opinions and Beliefs; and Clinical Practice. 130 copies were returned anonymously. A descriptive analysis of the frequencies was performed.
Results: The majority of the dentists (90%) had not received any training on stem cell therapies but many (73%) were interested in attending further training. Almost all participants (95%) would recommend regenerative therapies to their patients. The majority (80%) were willing to save teeth in cell banks for future therapeutic purposes.
Conclusions: Dentists are supportive of using stem cell and regenerative dental procedures and most are willing to undergo more training in regenerative dentistry. A majority felt that the topic should be included in the undergraduate course.
The capacity of the Oral Health Centre, University of Pretoria, to complete root canal treatments : researchSource: South African Dental Journal 71, pp 356 –360 (2016)More Less
Introduction: The University of Pretoria Oral Health Centre (UPOHC) is inundated by patients presenting with toothache, many requiring emergency pulpectomies (EPs). To date, the outcome of these procedures performed at this academic/public health facility, remains unknown.
Aims and objectives: To determine the completion rate of treatment of teeth that had received EPs at the UPOHC.
Study design: A retrospective survey of data obtained from electronic and paper records of 498 randomly selected teeth from the 1050 that had undergone EPs between 1 July 2012 and 30 June 2013 at the UPOHC, followed to 30 June 2014.
Methods: The outcome of treatment was recorded as "no treatment after initial pulpectomy", "pulpectomy repeated", "tooth was removed" or "root canal treatment (RCT) was completed by student or dentist".
Results: Of the 498 teeth included, 224 (44.98%) were obturated, 35 (7.03%) were retreated, forty two (8.43%) teeth were referred for extraction and 197 (39.56%) remained untreated. After 16.56 (SD 6.19) months, treatment remained incomplete in 46.58% (n=232) of cases.
Conclusions: The UPOHC lacked capacity to complete all RCTs that were started. A primary health care approach focussed on prevention combined with an integrated resource plan for oral health in the region is recommended.

If you have read this far - then you are ready to Research! So where, and how do you start? This paper is intended to guide and to stimulate novice researchers to take the plunge and delve into the exciting world of research and publication. A brief look at the "Instructions to Authors" of any reputable journal will give an indication of the many different types of papers that can be written, ranging from: Research and Education; Clinical Research; Case Reports; Dental Techniques; Material Sciences; Systematic Reviews; down to interesting or helpful Tips From Readers. The first step is to identify a problem, a clinical dilemma, a need, a new material or product to test, a novel idea, or an interesting clinical patient scenario to report on. You are now on your way to become the SMARTEST researcher - this acronym will be used as a guide on how to proceed.
Insights into the clinical effectiveness of whitening products - Part 1: dentist-supervised-at-home bleaching product : insightsSource: South African Dental Journal 71 (2016)More Less
This section of the report is about the success of a dentist-supervised-at home tooth whitener, giving the results of a clinical study. Opalescence PF 10% was applied for 14 days and the colour change followed over a 14 month period. It could be concluded that: a) Opalescence is a good tooth whitener, b) the time of re-bleaching should actually depend on the colour choice expressed by the patient. Overall re-bleaching should only be done after six months and not on a monthly basis, otherwise enamel damage may become a problem. Remember that peroxide, which is responsible for the bleaching process, is a strong oxidizing agent. Furthermore, A2 and darker teeth showed more aesthetically observable colour changes.

Anaphylaxis is a medical emergency that requires immediate recognition and intervention. Equipment and medication should be readily available. Early administration of adrenalin is the key to survival. In this paper we discuss the critical aspects of anaphylaxis: the definition, presentation, the pathophysiology, the best emergency management and measures to prevent recurrence.

A dentist places temporary crowns and a follow up appointment is made to place the permanent crowns, which are manufactured and ready for that appointment. Before the date of the appointment, the patient advises the dentist that he/she has consulted with another practitioner who has now placed the permanent crowns. This is done without the patient terminating the contract with the dentist or settling outstanding fees due.
