Activated charcoal HP paste was prepared for both groups. The laser enhanced 6% HP group received a dosage of 90 J/cm² per bleaching cycle using 810nm diode laser. Tooth colour was measured at the beginning and end of each session registering parameters L*, a* and b*, and tooth sensitivity. The calculated difference between these parameters, ΔΕ, was the primary data focus. The mean ΔΕ over the treatment duration was used to answer the research question by a t-test to evaluate group differences at 5% significance level. RESULTS: The analysis revealed that the null hypothesis could not be rejected and the results were inconclusive. CONCLUSION: The observations expound the idea of an absorption enhancement mechanism, rather than a free radical activation, as the technique for improving bleaching outcomes. <![CDATA[<b>Examining the effect of exposure time on the erosive potential of sour candy</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162021000200005&lng=pt&nrm=iso&tlng=pt AIM: This study aimed to evaluate the erosive potential of sour candy at a different time of exposure within a laboratory-based setting. MATERIALS AND METHODS: Fifty human anterior tooth samples were randomly assigned into three groups, namely: sour candy, regular candy A, and deionized water (n=15). Each tooth samples was exposed to a solution containing the sample groups at different time intervals. Vickers hardness tester was used to measure the surface hardness pre- and postexposure. The mean surface hardness value measured was compared using a paired sample test (α = .05). Raman spec-troscopy was used to study the change in the enamel structure in all sample groups. RESULTS: A significant difference in the surface hardness value was measured pre and post-exposure in all the sample groups (P<0.01). The samples exposed to sour candy had the highest tooth surface loss. In terms of the time of exposure, it was found that prolonged exposure had a significant effect on the surface hardness (P<0.01). The Raman intensity change confirmed that samples exposed to sour candy, after 2hrs of exposure, had the highest loss of structural integrity. CONCLUSION: The study conclude that sour candies are very erosive and its impact enhances with time. <![CDATA[<b>Botox in periodontics - Exploring new avenues</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162021000200006&lng=pt&nrm=iso&tlng=pt From a periodontal point of view, various factors contribute to facial aesthetics. In the recent past, studies have revealed that excessive gingival display is a factor that influences an individual' smile line. Some literature exists to support that more than excessive gingival display of more than 3mm is considered unaesthetic and termed a 'gummy smile' (GS). The prevalence of gummy smile' has been 10% and to be more common in females. Gingival hyperplasia altered passive eruption, vertical maxillary excess, and upper-lip hypermobility can all result in excessive gingival display when a patient smile. To select the correct treatment protocol, accurate diagnosis is essential. Various techniques have used to treat gummy smile which includes surgical and non-surgical methods. Recently nonsurgical method using Botulinum toxin gained polarity considering that the method is minimally invasive. <![CDATA[<b>Review of the radiographic modalities used during dental implant therapy - A narrative</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162021000200007&lng=pt&nrm=iso&tlng=pt The introduction of digital x-ray receivers which replaced conventional films was a significant radiographic development that is commonly used in daily dental practice. Dental implant therapy (DIT) is a sought after dental therapeutic intervention and dental radiography is an essential component contributing to the success of treatment. Dental radiographs taken in daily practice are generally conventional two-dimensional images and/or three-dimensional images. Ideally, the choice of radiographic technique should be determined after a thorough clinical examination and comprehensive consideration of the advantages, indications, and drawbacks. Digital three-dimensional modalities that have emerged over the last decade have been incorporated into DIT with the assumption that treatment outcomes will be improved. These modalities are constantly being reassessed and improved but there is a paucity of published information regarding the assessment of variables such as dosages and dimensional accuracy, suggesting that further research in these matters is necessary. This is crucial in order to obtain evidence-based information that may influence future radiographic practices. In this narrative, the authors present the most commonly used dental radiographic modalities currently used in DIT. <![CDATA[<b>Macrodontia and Dens Invaginatus- Review of the literature and a case report</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162021000200008&lng=pt&nrm=iso&tlng=pt Disturbances in histodifferentiation and morphodifferentia-tion may include genetic or environmental factors. These disturbances often lead to dental anomalies. This paper reviews the aetiology, clinical and radiographic appearance, diagnosis and treatment options for macrodontia and dens invaginatus respectively. A rare case is presented in which the two anomalies occurred directly next to each other in the anterior dentition of a young boy. The diagnostic process and management are reported with a detailed explanation of the use of modern diagnostic aids and equipment. The procedure of apexification is also described in detail as both anterior teeth were still immature when they turned necrotic. A 2-year follow up reported the successful treatment resolution of infection and associated symptoms, as well as restoration of function and aesthetics. <![CDATA[<b>What's new for the clinician? - Excerpts from and summaries of recently published papers</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162021000200009&lng=pt&nrm=iso&tlng=pt Disturbances in histodifferentiation and morphodifferentia-tion may include genetic or environmental factors.
