LEGAL TALK with Hahn & Hahn Attorneys: PIE Amendment Bill

This week we focus on the PIE Amendment Bill and what it changes in South Africa’s eviction laws. We look at why the Bill is needed, what new offences and penalties it introduces, and how it affects municipalities and state responsibilities. We also examine whether vulnerable occupiers are still protected and what the broader impact will be on property owners, developers, and the economy. Joining Eon is Nirvana Nothnagel of Hahn & Hahn Attorneys. Legal Talk is aired every Wednesday morning at 10:00 on eRadio and available as a podcast thereafter.

The OPTISMILE Podcast 109 - Airway Orthodontics & Palatal Expanders

Introduction A child's upper jaw shapes far more than the alignment of their teeth. It forms the floor of the nasal cavity and directly governs how easily they breathe, how deeply they sleep, and how their face grows over a lifetime. A narrow palate is not simply a cosmetic orthodontic concern — it is a functional one with wide-reaching consequences for health, behaviour, and development. In this episode, Dr Clifford Yudelman of OptiSmile Advanced Dentistry and Implant Centre in Sea Point, Cape Town, explains what palatal expanders are and how they work, the differences between fixed metal and Invisalign-based expansion systems, the critical window for intervention in growing children, and why early expansion can prevent extractions, surgical procedures, and a cascade of harder problems later in life. Topics covered include the relationship between a narrow palate and nasal airway resistance, the surprising link between jaw width and bed wetting in children, what happens to the face profile when teeth are extracted unnecessarily, the current limits of adult expansion, and the specific signs parents should look for at home right now. Episode Questions and Answers Question 1  (1:06) How does a narrow palate affect a child's ability to breathe? The palate forms the floor of the nasal cavity, so a narrow palate directly constricts the nasal passages. Children develop increased nasal resistance, become habitual mouth breathers, and are vulnerable to poor sleep, snoring, behavioural issues, and altered facial growth. Question 2  (2:31) What on earth is a palatal expander, and does it hurt? An orthodontic appliance that widens the upper jaw by separating the mid-palatal suture. In children the suture is still flexible, so expansion is biologic rather than surgical. Most children feel pressure rather than pain, with mild tightness after activation that settles quickly. Question 3  (3:51) What is the Invisalign Palatal Expander and how is it different from metal ones? The traditional metal expander is fixed to the molars and turned daily by a parent. The Invisalign system uses a digitally planned series of removable clear expanders. It is more comfortable, easier to clean, and better accepted by children. Correct diagnosis and timing matter more than the device chosen. Question 4  (5:19) Can expanding the jaw prevent the need for removing teeth later? In most cases, yes. Widening the arch increases both width and perimeter, giving teeth space to erupt naturally. Multiple studies confirm early expansion reduces the need for future extractions. Unnecessary extractions narrow the arch and can flatten the facial profile significantly. Question 5  (7:12) How is bed wetting linked to airway issues and even narrow jaws? Nocturnal enuresis can be linked to sleep-disordered breathing. Poor oxygenation and frequent sleep arousals disrupt the hormonal signals involved in bladder control. Improving airway patency through nasal breathing can help in airway-related cases. Question 6  (8:10) Is there an age limit for expanding the palate? Expansion is most effective in children and early adolescents while the mid-palatal suture is still open. As skeletal maturity increases, non-surgical expansion becomes less predictable. An orthodontic screening at around age seven is the recommended starting point. Question 7  (9:20) How does airway orthodontics improve sleep quality for children? Palatal expansion increases nasal airway volume and reduces airflow resistance. This supports deeper, more stable sleep cycles. Parents typically report reduced snoring and improved daytime focus and behaviour. Sleep studies confirm measurable improvements in airflow after expansion. Question 8  (10:16) Can adults benefit from expansion or is it surgery only for them? Adults can benefit but the fused suture means conventional expansion tends to tip teeth rather than widen the skeleton. Surgery-assisted or TAD-supported expansion can achieve skeletal change. Dr Yudelman cautions that this is being heavily oversold and would not currently refer his own patients for the surgical route. Question 9  (11:18) Does expansion change the shape of the face or even the cheekbones? In growing children, expansion supports more balanced facial development and a broader smile. Changes are gradual and harmonious. Claims of dramatic adult facial transformation should be treated with scepticism. Function is the primary goal; aesthetics are secondary. Question 10  (12:10) What signs should parents look for to know if their child needs this? Watch for chronic mouth breathing, snoring, a narrow smile, crowded teeth, dark circles under the eyes, and frequent fatigue. A simple home check: tilt the child's head back. A flat, wide palate is normal; a deep V-shape is a prompt to see the dentist. Outro Airway orthodontics may be one of the most underappreciated areas in modern dental practice. A child who breathes better sleeps better, learns better, and grows better — and the window for non-surgical palatal expansion is narrow and biologic, which is why early screening matters so much. The dentist who looks at a seven-year-old's crowded smile and sees only teeth is missing most of the picture. Look at the airway. An orthodontic assessment at around age seven allows for the simplest, safest, and most effective interventions — ones that can prevent years of complex and expensive treatment later. Next week's episode covers TADs — temporary anchorage devices — the small titanium screws used in orthodontics to create fixed points that help move teeth predictably.

The OPTISMILE Podcast 108 - Biological vs Evidence-Based Dentistry

Intro The biological dentistry movement is everywhere on social media, with claims that fluoride is toxic, silver fillings poison the body, and root canals cause cancer. None of these claims hold up under scientific scrutiny, yet they continue to drive patients into expensive and often unnecessary treatments. In this episode, Eon Engelbrecht speaks with Dr Clifford Yudelman about the difference between biological dentistry as a philosophy and evidence-based dentistry as a discipline, and how patients can tell them apart. They cover fluoride, amalgam removal, root canals, biocompatibility claims, ozone therapy, metal-free marketing, and the question of whether a modern practice can be both high-tech and genuinely whole-body aware. 10 Questions with Summary Answers 1. [0:41] What is the difference between a biological dentist and a traditional dentist? Biological dentistry is a philosophy, not a formally recognised specialty or regulated discipline. At its best it reflects a genuine interest in how dental treatments affect the whole body; at its worst it drifts into claims unsupported by evidence. Evidence-based dentistry, by contrast, is clearly defined: it combines the best available scientific research with clinical expertise and patient values, and is endorsed by international dental organisations and taught at universities worldwide. The fundamental difference is that evidence-based dentistry asks what high-quality research shows is safe and effective, while biological dentistry sometimes starts with a belief and then looks for supporting arguments. 2. [2:14] Why is there so much controversy around fluoride in the biological community? Fluoride is one of the most studied substances in public health, and decades of high-quality research show that at appropriate doses it significantly reduces tooth decay. The controversy largely stems from a misunderstanding of dose versus toxicity. Almost any substance, including water, can be harmful at extreme levels, but the fluoride concentrations in toothpaste and community water are far below toxic thresholds. Systematic reviews from reputable organisations consistently conclude that fluoride is safe and effective when used as recommended, and claims linking it to widespread systemic disease are not supported by robust evidence. 3. [3:32] What is the scientific stance on amalgam fillings and routine removal? Dental amalgam contains mercury in a stable, bound form, and large-scale studies have found no evidence that amalgam fillings cause systemic illness in the general population. Unnecessary removal can actually increase mercury exposure temporarily and damages otherwise healthy tooth structure. There are valid clinical reasons to replace amalgam fillings such as fractures, decay, or cracking, but routine wholesale removal as a supposed cure for arthritis, joint problems, or other systemic conditions is not supported by science. The clinical principle is straightforward: replace amalgam for a clinical reason, not because of a promise that it will detoxify the body. 4. [5:53] Are root canals really as toxic as some documentaries claim? No, and the documentaries claiming otherwise are based on poorly designed studies from over a century ago that have been repeatedly disproven. Root canal treatment is one of the most thoroughly studied procedures in dentistry, and high-quality evidence shows that a properly performed root canal removes infection, eliminates pain, and preserves the natural tooth. Modern microbiology, imaging, and materials have dramatically improved outcomes. The fear-based content circulating online relies on outdated and misrepresented data rather than current science. 5. [7:28] What does biocompatible actually mean when you choose dental materials? Biocompatible means a material performs its intended function without harming surrounding tissues. All modern dental materials are tested extensively for biocompatibility before approval. No material is completely inert, but the goal is predictable performance, durability, and minimal adverse response. Marketing sometimes misuses the term biocompatible to imply superiority without evidence. Material selection should be guided by clinical indication, longevity, and proven outcomes, not by labels or testimonials. 6. [9:44] At OptiSmile, how do you balance holistic health with scientific evidence? Whole-body health is inseparable from oral health, and the links between gum disease, diabetes, and cardiovascular disease are well supported by research. The balance lies in respecting these links without overreaching. Dr Yudelman regularly refers patients for blood tests, sleep studies, ENT input, or cardiology assessment when warranted, but is clear that dentists specialise in the oral cavity and should not be diagnosing conditions outside it. The approach is integrative but conservative, guided by science and tailored to each individual patient. 7. [11:21] What is ozone therapy, and does it actually work for teeth? Ozone has antimicrobial properties and has been studied as an adjunct in dentistry, with some evidence it can reduce bacteria in certain situations. Current systematic reviews do not support ozone as a replacement for conventional treatment such as cleaning out a cavity and placing a filling. Claims that ozone alone can heal a cavity without restorative work are not mainstream and lack solid research support. Dr Yudelman has not found a useful clinical role for it in his own practice. 8. [13:14] Why should patients be wary of metal-free claims if they are not backed by science? Metal-free marketing capitalises on the genuinely poor reputation of older base metals like nickel-containing alloys, but modern restorative materials are very different. Lithium disilicate (Emax) and zirconia bond well, are extremely strong, and are highly inert; zirconia in particular integrates so well that the gum almost glues itself to a zirconia crown. The absence of metal does not automatically make a restoration safer or healthier — every material has strengths and limitations. The biggest concern is when metal-free messaging extends to discouraging titanium implants, which are the most thoroughly researched implant material in medicine and are routinely used for hip replacements and fracture fixation. 9. [16:02] Is it possible for dentists to be both high-tech and holistic? Yes, and modern dentistry increasingly blends advanced technology with preventive, patient-centred care. A proper new-patient examination at OptiSmile takes around 90 minutes and covers digital imaging, saliva, occlusal forces, diet, oral hygiene, gum measurements, AI-assisted x-ray analysis, and discussion of broader health factors such as blood sugar. The distinction Dr Yudelman draws is between a holistic approach grounded in science and an ideology that rejects established treatments wholesale. Good clinicians can do both; ideologues only do one. 10. [19:06] What questions should patients ask to ensure they are not getting quackery? The most useful question is simply: what evidence supports this treatment, and is it backed by peer-reviewed research? Modern AI tools like ChatGPT, Gemini, and Claude can summarise the published literature on any specific claim, such as whether titanium implants are toxic or whether ceramic implants are genuinely better. A useful sanity check is the global consensus test: if every major dental organisation in the world recommends one approach and a single practitioner in town claims to be the only one who is right, that imbalance is a signal, not a selling point. Transparency and willingness to explain the evidence are the hallmarks of ethical, evidence-based care. Outro This episode draws a clear line between two very different approaches to dentistry. Evidence-based dentistry combines high-quality research with clinical experience and patient values. Biological dentistry, in its more extreme forms, starts with a belief and looks for supporting arguments afterwards. Both can sound caring on the surface, but only one is grounded in science. For any treatment that sounds like a miracle cure, the right questions are simple: what evidence supports this, is it peer-reviewed, and do other major dental organisations agree? If one practitioner is the only one in town claiming to be right, that should be a signal rather than a selling point.
