MATERIALS AND METHODS: A retrospective observational cohort study of patients treated at a surgical private practice. Primary outcomes were three year cumulative implant and prosthesis survival. Secondary outcomes were surgical or prosthetic complications not resulting in implant or prosthesis loss. Marginal bone loss, measured on standardized panoramic radiographs was recorded if the loss exceeded Albrektsson's standards (less than 1 mm in the first year and maximum of 0.2 mm per year thereafter). RESULTS: Twenty-five patients (15 women, 10 men) were reviewed, with 124 implants supporting 31 full-arch fixed prostheses. Twenty had greater than three year follow-ups (range 40.7-139.7 months, mean 96.9 months), comprising 96 implants, and 26 jaws. Three implants failed in two patients, (survival rate 97.9%). One prosthesis failed (96.2% survival rate). Two patients required prosthesis replacement due to implant loss. One abutment screw fractured, which required replacement. A total of seven implants, in four different patients, had marginal bone loss in excess of the Albrektsson norm. CONCLUSION: This study found that the reliability and predictability of the All-on-4® concept is verifiable for the treatment of total edentulism. <![CDATA[<b>The antibacterial effect of herbal alternatives, Triphala and Turmeric, on Enterococcus <i>faecalis</i> - an <i>in vitro </i>study</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000600005&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Disinfection and shaping of the canal with a combination of chemical agents and endodontic instruments play important roles in the success of endodontic therapy. Root canal irrigants aid in achieving disinfection in canal systems inaccessible to biomechanical preparation A wide variety of synthetic irrigants are available today but some may be ineffective, and there may be safety concerns and side effects. Herbal alternatives may be advantageous. AIMS AND OBJECTIVES: To evaluate the antibacterial properties of herbal extracts, namely turmeric and triphala as irrigants during endodontic treatment in comparison with the conventional irrigating solutions. MATERIALS AND METHOD: Agar well diffusion assay and MIC methods were used to determine the efficacy of the experimental irrigant in removing E. faecalis. The difference between groups was statistically analysed. RESULT: 2% chlorhexidine showed the highest zone of inhibition against E. faecalis followed by triphala. There was no significant difference between triphala and turmeric but triphala showed more inhibition effect against E. faecalis because of chelating properties CONCLUSION: Chlorhexidine has significant antimicrobial efficacy against E. faecalis. Considerable reduction in growth of E. faecalis was seen in the herbal extract groups and considering their non-toxic nature and other physiological benefits, further studies are warranted. <![CDATA[<b>Prevalence of peri-implant mucositis at single tooth bone level dental implants in a South African population</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000600006&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Peri-implant mucositis (PIM) is characterized by inflammation of the soft tissues surrounding dental implants. It affects 43% of implant patients on average and despite its reversible nature, it can, if left untreated, progress to peri-implantitis and potentially implant failure. To date, there is a paucity of data on the prevalence of PIM in South Africa AIMS AND OBJECTIVES: To determine the prevalence of peri-implant mucositis in patients from the Faculty of Dentistry of the University of the Western Cape, and to evaluate potential risk factors including systemic (smoking, diabetes), implant-related (implant position and diameter, connection and crown) and soft tissue-related (keratinized gingiva, oral hygiene) issues. DESIGN: Cross-sectional cohort study METHODS: A total of 74 partially edentulous patients with at least one implant that had been restored with a single crown for at least 12 months were clinically examined. RESULTS AND CONCLUSIONS: PIM was highly prevalent (70.3% of the sample), highlighting the need for maintenance programs for the long-term success of dental implants. Anterior location of the implant, poor oral hygiene, pre-operative oral hygiene instructions and a wide band of KM were associated with PIM. However, due to the limited sample size, these findings should be interpreted with caution. <![CDATA[<b>Prevalence of impacted third molars in the South African Indian population of the eThekwini Metropolitan Region</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000600007&lng=pt&nrm=iso&tlng=pt INTRODUCTION: An impacted tooth is partially erupted or un-erupted, positioned against another tooth, bone or soft tissue in such a way as to prevent further eruption. Normal dental arch relationships are disrupted This study investigated the prevalence of impactions of third molar teeth amongst Indians residing in the greater eThekwini Metropolitan area. MATERIALS AND METHODS: A sample of 274 digital panoramic radiographs was examined. Impacted third molars were identified on 222 scans. The impactions were classified using Winter's, and Pell and Gregory's schemes. Statistical analysis was applied to determine any relationship between impac-tions and sex and age. RESULTS: Eighty-one percent of individuals presented with at least one impacted third molar, mandibular frequency being significantly higher in both sexes (p-value = 0.000). The most prevalent types of impaction were mesio-angular (mandibular)and vertical angulation (maxillary For level of impaction, Class B and Class A were respectively most prevalent in the mandible and the maxilla. With the exception of angulation of impacted mandi-bular third molars on the right side, all parameters showed a statistically significant correlation with age (p-value=0.000). CONCLUSION: The high frequency of these eruption problems in this study may alert maxillo-facial and dental surgeons, and forensic investigators, to potential clinical challenges <![CDATA[<b>Dental malpractice cases in South Africa (2007-2016)</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000600008&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Malpractice complaints against oral health professionals (OHPs) are increasing globally, and include breach of confidentiality, failure to obtain valid informed consent, issuing fraudulent medical certificates, claiming for services not rendered and violating regulations governing the dental profession South African dentists were most commonly charged with clinical complaints (59%) whilst 29% of dental cases and 46% of dental therapist cases were for fraud. AIMS: To analyse the nature and outcome of malpractice by OHPs as reported by the Health Professions Council of South Africa (HPCSA). METHODS: A cross sectional descriptive survey of the data between 2007-2016. RESULTS: 118 cases and 198 counts of dental malpractice were identified, predominantly by dentists (74.6%), then specialists (17%) and dental therapists (11%). Males recorded 77.1% of complaints, Gauteng practitioners, 53.4%, and 53.8% were OHPs who had worked for 10 years or more. Approximately a third (37%) of the OHPs had more than one count of malpractice. Mean ages for independent practice were calculated. Fraud, clinical misconduct and unprofessionalism constituted 66.7%, 23.2% and 10.1% of all counts of malpractice respectively, while there were significant differences between the involved dentists and dental therapists. CONCLUSION: Fraud remains the most serious and ever increasing form of malpractice among Oral Health professionals. <![CDATA[<b>Cephalometric analysis: manual tracing of a lateral cephalogram</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000600009&lng=pt&nrm=iso&tlng=pt Cephalometric analysis remains a preferred tool in the diagnosis and treatment planning of orthodontic and of orthognathic surgical cases. A cephalometric tracing can be prepared and analysed manually or by a computer using cephalometric tracing software. A number of software programmes on cephalometric analyses have been introduced but their widespread use has been restricted by cost factors, especially in situations having a constraint on resources. This report will give a step-by-step procedure to enable the identification of cephalometric points and planes used in orthodontic diagnosis and treatment planning and to facilitate the manual tracing of a lateral cephalogram. <![CDATA[<b>Age estimation of the skeletal remains of a child</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162019000600010&lng=pt&nrm=iso&tlng=pt Cephalometric analysis remains a preferred tool in the diagnosis and treatment planning of orthodontic and of orthognathic surgical cases.
