What is Augmented Reality?

Overview

Augmented reality(AR) can be described as the use of technology to overlay information on the real world that we can see. It is akin to virtual reality, but it aims at replicating the real-life environment on a computer. For instance, it superimposes sounds and images over what a user hears or sees. A good example of augmented reality and its defining concept of interactivity is what can be observed in the ‘Ironman’ movies.

Development

To many of us, augmented reality may appear to be very futuristic technology, but this may not be entirely true. Technology that applies some form of augmented reality has been with us for some years now. Looking back to the 90s,a lot of fighter aircraft were equipped with heads-up displays that displayed information pertaining to the plane’s altitude, speed and direction.Later, the displays were improved to show the pilot which objects appearing in the viewing field were to be considered targets.

 

Even further back in 1965,Ivan Sutherland of the University of Utah and a pioneering computer scientist gave a description of a wearable gadget that used a head-mounted display unit that employed half-silvered mirrors which allowed the wearer to view a virtual world that was overlaid on the real world. Three years later, he demonstrated his idea, and it was nicknamed the ‘Sword of Damocles’.

Over the last couple of years, a number of companies and tech labs have attempted to design devices that provide users with augmented reality. In 2009, Media Lab’s Fluid Interfaces Group of The Massachusetts Institute of Technology developed a device called the SixthSense. It hangs from the chest of the user and it uses a tiny projector, a mirror and a smartphone. There are four sensors on the fingers of the user through which they can manipulate the images that are projected by the device.

In 2013,Google Glass was rolled by Google, turn

ing the focus of augmented reality towards the more wearable interface of glasses. The device features a small screen on the lens through which a small projector displays images. It responds to voice commands and superimposes videos, images and sounds on the screen. However, the device was pulled from the market in December 2015- but plans are underway to design a new version.

Applications

In the recent past, various augmented reality applications have been developed for a number of industries. This has been helped by the increase in the popularity of smart devices and the general advancement in computing technology. This means the technology has immense potential in the consumer world of today. Education and gaming are two major areas that have experienced a lot of commercial growth in augmented reality. PlayStation and Xbox, the major video game consoles have incorporated augmented reality features in their last two generations of consoles.

In education and medicine,augmented reality using 3D models is being applied to enable better understand human anatomy or even help in surgery using infrared scanning imagery. In the military, heads-up displays can view information that is tagged onto real world objects.
Mobile phones like the iPhone have apps that enable users to view computer generated images that are overlaid on real life images. For instance there is an app that can help you locate a restaurant by displaying restaurant logos as you move in a specific direction.

The future

The cost and size of the basic apparatus needed for augmented reality such as computers, cameras and connectivity is reducing. At the same time their accuracy, resolution and speed is increasing rapidly. This means we are headed to an era where wearable computers will become a trendy accessory, helping to mediate our interaction between the digital and analog worlds.

Stress is a term used when you feel that everything is becoming too much on you. In the medical world, stress can be referred to as a reaction to a destabilization of both physical and mental equilibrium. When under duress or whatever stressing situation you are in; the body undergoes a ‘fight or flight’ mode triggering the release of hormones such cortisol and adrenaline. Well, that is a jargon for those who never did biology but simple enough to make you understand.

Mark you; stress is a normal part of life if managed well but can get out of hand and cause adverse effect to your health.

What causes stress?

There is no single collection of things that can be said to cause stress. Some people are stressed by small things in their life while it takes a tragic thing for others to be stressed. While stress can be caused by a myriad of things, here are a few common causes you should be aware of;

  • Poor health: conditions such as diabetes, heart diseases and arthritis among others are known to cause stress.

  • Positive thinking: even at the middle of problems you should see yourself as a winner. Do not give in to fate.
  • Keep good company: those around you would either help you deal with stress or make it worse. A good company is a plus if you want to beat depression.
  • Lead a healthy lifestyle: eating balanced diet, exercising, avoiding alcohol and finding time for fun would go a long way to help you evade or deal with stress.
  • Staying away from what stresses you. If you do some soul searching you will definitely find the things that stress you up. The solution is simple: stay away from them.

The Best Tooth Pain Remedies Available

Tooth Pain

Tooth pain can vary greatly from unbearable throbbing pain to mild soreness in your teeth or around your jaws. The causes of the pain on the other hand may range from problems like tooth sensitivity, trauma, dental abscess, infection, dental caries to periodontal disease. Fortunately, there are so many tooth pain remedies available but we are only going to look at a few. These remedies have been tried and tested to be safe so the next time you or your loved one experience a tooth pain, try one of these remedies and you will not be disappointed.

1. Clove oil

Clove oil contains a chemical compound called eugenol which is a natural anesthetic and has antioxidant properties. What’s more, clove oil is antibacterial in nature so it can also help you in reducing the risk of bacteria infections too. However, clove oil needs to be used carefully so it doesn’t come in contact with other sensitive areas of your mouth because it can make the pain worse. So to get rid of the pain, put a drop or two of the oil onto a cotton ball and place it against the tooth itself to numb the area until the pain recedes.

2. Vanilla extract

Alcohol is one of the main active ingredients in vanilla extract hence plays a big role in relieving tooth pain by acting as a numbing agent. On the other hand, the therapeutic properties of this remedy are also as a result of eugenol, a natural anesthetic. To use vanilla extract for tooth pain, you can either dab a small amount on your finger and rub it around the affected area or apply it to a cotton ball and place it on the affected area. And if the pain doesn’t go away completely, you can repeat the process 2 to 3 times a day.

3. Garlic and Onion

Use of garlic and onion can also provide immense relief from tooth pain. Garlic has some antibiotic and anti-inflammatory properties effective in getting rid of the pain while onions have bactericidal and antiseptic properties that can provide relief by killing the germs causing the infection. To alleviate the pain, chew or place a slice of onion directly on the affected tooth or gum for just a few minutes (if you’re not able to chew it) or chew one or two cloves of garlic to relieve the pain.

4. Asafoetida

This is a gum resin that is believed to be rich in both minerals and vitamins. It is also believed to have some therapeutic properties which is the reason it is one of the best tooth pain remedies. For the remedy to be effective, you need to make paste by mixing a few drops or two teaspoons of lemon juice with a pinch of powdered asafoetida and then soak a clean cotton pad in the paste to apply it on the affected tooth. This will give you quick relief from pain.

5. Over-the-counter painkillers

Over-the-counter pain medication can also be taken to get relief from the tooth pain. However, sometimes this is definitely not the best treatment option. The best remedy would be to consult a dentist so the underlying cause of pain is identified and treated at the earliest. This is especially if the pain is accompanied by swelling around the affected area, fever or even headache.

Bottom Line

Tooth pain is more likely to affect people who don’t follow a proper dental hygiene regimen. So it is very important to maintain good oral hygiene by brushing your teeth at least twice a day and going for dental checkups at least twice a year.

How Dental Health Affects Your Body

Oral Health

Your dental health is very vital than you might realize. Your dental health has significance to your overall body health. If you have good dental health, it means that you also have good overall body health. This is why it is necessary to ensure that you maintain good dental health. To help you gain more understanding, here are some of the ways on how dental health affects your body.

This happens because gum diseases enhance the inflammation throughout your body, leading to cardiovascular disease. Studies have shown that people suffering from periodontal disease are at higher risk of suffering from heart diseases and fatal heart attack. Gum disease as a result of extended bacterial exposure can cause cardiovascular disease.

Dental health and diabetes

It is known that people suffering from diabetes have higher risk of suffering from gum disease. However, studies have also shown that severe gum disease can also lead to diabetes as it affects the control of blood glucose in the body. Since periodontal disease is a type of infection, bacterial produce toxins that has effects on carbohydrate metabolism in the cells. This increases insulin resistance leading to diabetes.

Lung infections and oral health

People suffering from dental health issues such as periodontal disease have high number of bacteria breeding in their mouths. This also increases inhaling of germs leading to lung infections such as pneumonia. For those with preexisting problem of the lungs, gum disease makes the problem worse.

Dental health, pregnancy and your baby Studies have revealed that pregnant women suffering from progressive gum disease have high risk of suffering from gestational diabetes. They also have higher risk of delivering low birth weight or pre-term baby. During pregnancy, it is important to have regular dental checkups with a hygienist and dentist. Babies that are born with low birth weight have higher risks of developing complications such as asthma, infections of the ear, behavioral difficulties and birth abnormalities. Teeth grinding and joint health In most cases, bruxism is mild. However, when it is severe and frequent, teeth grinding can lead to aggravation of joints in your lower jaw. This leads to tightness or pain in the joint area, headaches and earaches. Bruxism can also lead to wearing down of your enamel leading to more tooth sensitivity and broken teeth.

Common Oral Surgery Procedures

Oral care, as an essential part of overall health, sometimes entail having to undergo surgery. Various procedures may be performed in accordance with several conditions, and there’s no harm in ensuring you are prepared when the need arises by knowing some facts and what you can typically expect at the clinic. Here are the most common dental surgery procedures that oral surgeons perform:

Tooth Extraction

The most common of all procedures would be tooth extractions, especially when the third molar or wisdom tooth is impacted. This occurs between the gums and the jawbone, wherein the tooth forms in a position where it can’t grow into the bite properly. It does not fully erupt or may not be properly aligned, thus affecting surrounding teeth. Even if symptoms are actually not yet prominent. minor surgery would be required to remove impacted wisdom teeth, often done in the dental office using sedation dentistry techniques.

Corrective Jaw Surgery

There are instances wherein orthodontics alone cannot address the problem when a person’s jaws are not properly aligned, Whether due to congenital abnormalities, skeletal problems, or a severe orthodontic condition, it causes major issues in both function and appearance. Surgical treatment is usually necessary in order to correct this problem and restore functionality. Jaw surgery is typically performed under general anesthesia, whereby the bones of the face and jaw are reshaped and repositioned, as well as the teeth and jaw realigned.

Dental Implants

Missing teeth does not only affect aesthetics, but a person’s confidence as well aside from potential issue detrimental to oral and general health. A dental implant is a permanent solution to replace a missing tooth, which is the closest you can get to the looks and feel of natural teeth. A metal post is surgically implanted into the jawbone, which will eventually be fused with the gum tissue and bone to create a strong foundation that will securely hold the artificial tooth in place. Depending on the jawbone condition, either it’s not thick enough or too soft, bone grafting may be required prior to the dental implant procedure itself.

Oral Biopsies

If there’s an unusual lesion in the mouth which cannot be diagnosed based on history and clinical findings alone, a biopsy can be performed as a diagnostic tool. A small piece of tissue will be removed during dental surgery, which will then be sent to the lab for assessment and analysis of the lesion, and checked for oral cancer

Obstructive Sleep Apnea

In cases where conservative treatments are unable to help serious sleep apnea sufferers, then dental surgery can be a good option. Upper airway surgery can be performed or excess tissue from the back of the throat may be removed to significantly reduce the symptoms of this obstructive condition.

Reconstructive Surgery

One of the common dental surgery procedures done to replace missing or damaged teeth, or tooth that has been knocked out due to facial injury is reconstructive surgery. Everyday functions such as eating and speaking can be quite a challenge, and reconstructive treatment can effectively repair jawbone and gum damage as well as jaw joint issues.

If you’re looking for a qualified oral or dental surgeon and you live in the Orange County or specifically the Garden Grove area, you should consider inquiring at a local Garden Grove dental service if you have any questions. The best thing you can do as an oral surgery candidate is to educate yourself on the procedures detailed above, and ask the right questions. This will give you more confidence before going into your oral surgery procedure.

Consider The Following When Looking For A Dentist

dentistThere are many things that should be taken into account as you look for a dentist. You need to start by finding a Dentist that is going to be able to provide you with incredible services at a cut cost. There are many things that need to be taken into consideration as you are looking at different dentists, in order to find the right one for yourself. A few of the things that you should be taking into account when you are evaluating dentists include price.

Start By examining the price. A large majority of people are going to have dental insurance, which means that their insurance is going to be paying for most of their dental procedures. However, this is not going to be the case for everyone. There is always going to be some people that are going to have a number of problems, and they especially need to be paying special attention to the price.

Dental procedures can be very expensive. If you are not going to be able to pay for dental procedures, you need to find a dentist that is going to allow you to pay for things with the cash discount. If you do not have insurance that covers dental, then there is a number of options available to you. Sometimes, you can purchase only dental insurance for a very low cost, or you can agree to cover amounts of two a few hundred dollars, with only the larger examinations and surgeries coming out of the insurance. This can help you to reduce your rate, and still get the dental care you need.

Availability

Also, take the availability of any dentist into account. Remember that if you are having an emergency, you will often need dental work right away. This means that your dentist needs to be willing to be on call at times, or have a very flexible schedule with his other appointments. For instance, some dental surgeons are not going to be able to move appointments, which means that you will not be able to see the dentist for quite some time. You need to make sure that you can always get access to them when you require it, and that they are always going to work to ensure that you are able to get the care that you need, whenever you need it.

Experience

You should also be looking for a dentist that has a lot of experience in the field, as well as a lot of satisfied customers that have been happy with their work. If they are unable to provide you with exactly what you are looking for, then you should always be willing to make changes to your schedule. Take your time, and make sure that you are looking at all available options, and are not jumping to any conclusions throughout the process. Finding the right dentist can save you a lot of headaches down the road, so make sure that you are taking your time to find the right one now.
