Dental X-rays are a common feature of routine dental visits, but the debate around their necessity and safety keeps resurfacing time and again. Over the years, concerns about their overuse, potential health risks, and financial costs have prompted questions about whether these radiographs are truly necessary or not. In 2012, a study published in the peer-reviewed journal Cancer suggested that dental X-rays could cause meningioma, a type of tumour that grows in the membranes that cover the brain and spinal cord. However, later scientists pointed out the study’s flaws, including its reliance on patients' recollection of their X-ray history—a method prone to inaccuracies. Further research found no significant link between full-mouth X-rays, which deliver higher radiation doses, and meningioma. The debate reignited in 2016 when a health economist highlighted the financial incentives of routine X-rays. Most recently, a 2024 article in Ars Technica questioned the evidence supporting routine dental X-rays, prompting discussions on whether these procedures should be reconsidered.

Here's What Science Says

Dental X-rays, particularly bitewing X-rays, are commonly used to detect cavities and monitor oral health. However, some studies suggest they may not always be necessary. A Brazilian trial on preschoolers found that visual inspections by dentists often matched or even outperformed X-rays in detecting early cavities. Similarly, reviews by the Cochrane Collaboration noted that X-rays can sometimes miss cavities or provide false negatives. Despite these findings, much of the research on dental X-rays is of low quality or conducted on extracted teeth rather than live patients, making it difficult to draw definitive conclusions.

What Are The Risks?

Dental X-rays are performed by emitting a controlled burst of radiation, which passes through the jaw and teeth to create detailed images of their internal structures. However, the radiation exposure from dental X-rays is minimal. A single bitewing X-ray delivers a dose of 0.3 to 5 microSieverts (µSv), far lower than a chest X-ray (100 µSv) or a head CT scan (1,000 µSv). Even dentists who perform multiple X-rays daily are exposed to radiation levels well below the permissible limits for healthcare workers. Modern practices, such as digital X-rays, further minimize radiation exposure.

How Can You Ensure A Safe Dental X-Ray?

Dental associations emphasize that X-rays should not be taken routinely or based on fixed schedules. Instead, dentists should assess a patient's risk factors, oral health, and symptoms before recommending radiographs. For example, the American Dental Association suggests intervals of 6 months to 3 years between bitewing X-rays, depending on a patient's age and risk for cavities.

While some dentists may overprescribe X-rays for financial gain, others adhere to the ALARA principle-Low As Reasonably Achievable. This approach ensures radiation exposure is minimized without compromising diagnostic accuracy.

Routine dental X-rays can help monitor oral health, but their necessity depends on individual circumstances. If you are concerned about radiation or cost, do not hesitate to ask your dentist about the rationale behind their recommendation. More robust research is needed to determine the true benefits and risks of frequent dental X-rays, but for now, the dose remains minimal and unlikely to harm most patients.

We have all have experienced fevers, there are many different beliefs about it in different cultures and multiple ways to treat it, ranging from modern medicine to ancient practices. When one has a fever, their body feels warm and weak, they also do not have energy to do extended movements. As fevers are a range, some being slight to others being signs of dangerous conditions, dealing with them can be tricky. Things like fever dreams, conversations and thoughts are often incoherent. There are things called fever hallucinations as well, but why does this happen?

Fever means your body temperature has gone above what's normal. But what's "normal" can be a bit different for everyone and can change based on how active you are and the time of day. Generally, a fever is when your temperature is higher than 99 degrees Fahrenheit in the early morning or above 100 degrees Fahrenheit at any other time.

Do Fevers Make Us More Irritable?

In a 2013 review published in the Journal of Pain and Symptom Management, the researchers found that not only do fevers cause people to feel cold, weak and other bodily sensations, but the participants also expressed emotional changes, vivid dreams/hallucinations.

In one of the interview with a participant from the study, researches noted them experiencing feelings of anxiousness, crabby, angry and frustrated, “Like I said, I think fever is really tied in to how you feel emotionally. Because I know every time I have a fever, I just get snotty, for lack of a better term, because I'm just really agitated.”

“I feel tired. I feel irritable”

How Is Body Heat And Brain Health Connected?

Harvard Heath explains a part of your brain called the hypothalamus acts like a thermostat for your body. When you're healthy, it keeps your body at its usual temperature. A fever happens when the hypothalamus gets set to a higher temperature than normal. This change in the brain's thermostat is usually caused by tiny things in your blood called pyrogens.

According to a 2023 review by Yale School of Medicine heat can change things in the environment, it can also change how our brains work. In a study, researchers found that even small increases in temperature while the brain is active can really change what the brain does, and sometimes these changes can be negative.

Experts from Yale explain that changes in temperature in the brain also affect how our nerve cells (neurons) fire signals. These cells have tiny pumps that give them electrical energy, which they release when the brain is active. The researchers found that if brain cells get heated up too fast, faster than these pumps can adjust, the cells might become more active or less active than usual.

Even tiny temperature changes from brain stimulation can lead to big changes in neuron activity. As neurons get warmer, they can even stop working, and when they cool down again, they can become very easily excited.

Fever Hallucinations and other Psychological Affects

According to an Infections & Chemotherapy 2022 review, fevers can cause febrile convulsions, which is a seizure caused by a fever in young kids. It can also cause confusion, like not understanding where you are, not recognizing your surroundings. It can also cause unstable emotions, conscious and cognitive disturbances like illusions on hallucinations.

These can also be symptoms for things like influenza infections or encephalitis. Like the Yale experts explained even small temperature changes can have such a big impact on brain activity, we need to start paying attention to these small changes. He points out that it's a basic rule of physics that when you send electricity through wires to stimulate the brain, you will create heat, both in the wires and in the brain tissue itself.

Researching more on these matters can help us find better treatments and help doctors change the course of several procedures to help their patients.

Turkey has banned elective caesarean surgeries for childbirth at private hospitals and healthcare centres. "Planned Caesarean sections cannot be performed in a medical centre," said a gazette entry outlining new regulations governing private healthcare institutions in Turkey. It came as the country's president, Tyyip Recep Erdogan, has been pushing hard to have women give natural births, asserting that C Section surgeries promoted Western culture.

The move has triggered massive criticism from the opposition and right-wing organisations. "As if the country had no other problems, male football players are telling women how to give birth," Gokce Gokcen, deputy chair of the main opposition CHP, on X. Meanwhile, many human rights and women's rights organisations have also raised their voices against this new law, calling it out for restricting women's rights and liberty.

What Is A C-Section Birth?

C-section or caesarean birth is a surgical procedure wherein a baby is delivered through incisions made in mother's abdomen and uterus. The name caesarean comes from the Latin word "caedare" which means "to cut." Interestingly, there are rumours that link the name to Roman emperor Julius Caesar, stating that he was the first person to be born via this procedure. However, there are no records of this.

However, there are many cases where a caesarean section surgery becomes almost necessary. A doctor may order a C-section if:

• Your baby is breech, or the lower part of the body is in the birth canal instead of the head.
• Your baby is in a transverse position, or lying sideways in the birth canal.
• Your baby’s head is unusually large.
• Your baby’s heartbeat is slowing down, or there is a problem with oxygen delivery to your baby.
• You are giving birth to more than one baby. Sometimes one baby will be in an abnormal position, so all of the babies are then born via C-section.
• Your baby has a birth defect that makes vaginal delivery unsafe.
• You have umbilical cord issues.
• You have health conditions that make vaginal delivery unsafe. These include high blood pressure, HIV, open herpes lesions, or heart problems.

What Are The Complications Of Having a C-Section Surgery?

There are many complications that come with this method of delivering a child. They include:

• Reactions to the medicines used during surgery
• Bleeding
• Abnormal separation of the placenta, especially in women with previous cesarean delivery
• Injury to the bladder or bowel
• Infection in the uterus
• Wound infection
• Trouble urinating or a urinary tract infection
• Delayed return of bowel function
• Blood clots

Bottom Line

Despite the potential risks and complications, C-sections are much safer than they once were. With evolution in medical science, doctors are now taking great care to make incisions that will reduce the risk of nicks to the baby and infections to the mother. Meanwhile, the use of anaesthesia, also reduces the pain of the childbirth.

Being dishonest doesn’t come naturally to people, it is a learned virtue, whether out of necessity or pleasure. When kids lie, a lot of it stems from them not wanting to get in trouble, for example, breaking a household item or doing something they were told not to do like running around inside the house. However, when people do learn to tell lies, it can become like a go to tendency for many. It is easier to make something up rather than explaining complex truths.

According to a study published in the Psychological Science 2015, kids start lying around the age of two to three years old. Their habit then progresses rapidly, till the age of 3 and 7.

Not all lies are the same, some are really small and don't hurt anyone, like saying you like someone's new haircut even though you don't. These little white lies often just help keep things smooth and make people feel good. Then there are much bigger lies, like saying someone else did something wrong when they didn't, or lying to people about money. These kinds of lies can cause a lot of damage and have bad consequences for people's lives.

Stress Response of Lying

When we know that being dishonest could really hurt how others see us, the act of lying itself makes our bodies feel stressed. When we tell a lie, things start to happen without us even thinking about it. A 2015 review published in the Current Opinion in Psychology explains that our heart might beat faster, we might start to sweat a little and our mouth can feel really dry. These physical changes are what those old-fashioned lie-detector tests used to try and pick up on.

Some people don't feel as much empathy as others, and they might not have the usual stressed reaction when they lie. The American Psychological Association explains that some people can learn to control their bodies really well and might be able to lie and still pass a lie-detector test. On the other hand, someone who is telling the truth but is just really nervous about being tested might look like they are lying.

Gut-Brain Connection and Extreme Reactions

While it's not common, some people might have a really strong physical reaction to lying, like feeling sick to their stomach or even throwing up a lot. This shows how connected our gut and our brain are. When we feel really anxious, like when we are worried about getting caught in a lie, it can actually make our stomach feel bad. So, for someone who is constantly lying and worried about it, this anxiety could potentially lead to physical sickness.

Living a life where you are often not telling the truth can actually take a toll on your health over time, not just in the moment. Research has suggested that people who lie a lot might have problems like high blood pressure, their heart might beat faster more often, their blood vessels could get tighter, and they might have more stress hormones in their bodies on a regular basis.
