Teeth health

Implants are great for replacing missing teeth. It is important that you have enough bone in the area of the missing teeth for the implants to be attached to. Implants are not only used to replace one tooth, but rather people missing most, if not all, of their teeth benefit greatly as well. Implants are increasingly being used to replace certain types of bridges and removable partial dentures.

There are no known health risks of receiving composite fillings. If such a filling is not going to be enough to protect your damaged tooth, or if your tooth enamel is thin and will easily fracture, or if your tooth has had a root canal that weakened your tooth condition, your tooth may require additional protection such as a crown.

In other instances, crowns are used to replace a actual missing tooth. These crowns are anchored to the teeth on either side, with a bridge section connecting the two crowns. Instead of bridges, single tooth dental implants may be used that eliminate the need for supporting the crowns.

Take care of your skin

Skin has pigmentation, provided by melanocytes, which absorbs some of the potentially dangerous radiation in sunlight. It also contains DNA repair enzymes which reverse UV damage, and people who lack the genes for these enzymes suffer high rates of skin cancer. One form predominantly produced by UV light, malignant melanoma, is particularly invasive, causing it to spread quickly, and can often be deadly. Human skin pigmentation varies among populations in a striking manner. This has sometimes led to the classification of people on the basis of skin color. See the article on human skin color.

The dermis lies below the epidermis and contains a number of structures including blood vessels, nerves, hair follicles, smooth muscle, glands and lymphatic tissue. It consists of loose connective tissue otherwise called areolar connective tissue - collagen, elastin and reticular fibres are present. Erector muscles, attached between the hair papilla and epidermis, can contract, resulting in the hair fibre pulled upright and consequentially goose bumps.

Your skin is your armor, your shield from the elements. Yet when was the last time you really thought about what you need to do to take care of it? Throughout your life, genetic and environmental factors will cause a lot of wear and tear to your skin. But you are never too young or too old to start taking care of your skin.

Learn anxiety disorders

While both fear and anxiety can provoke an arousal response, their other effects diverge. Very intense fear sometimes serves to "freeze" the body to protect it from harm, causing little or no change in heart rate and blocking the impulse to move. In anxiety, the physical changes caused by arousal lead to a second stage marked by thought patterns such as worry, dread, and mental replays of anxiety-arousing events.

Psychoanalytic theory holds that anxiety stems from unconscious conflict arising from discomfort or distress during childhood. Once the source of the anxiety is identified, it can be eliminated by resolving the underlying conflict. However, most studies find that people with anxiety disorders come from stable homes, with childhood backgrounds similar to those of people without anxiety disorders.

Psychiatrists or other physicians can prescribe medications for anxiety disorders. These doctors often work closely with psychologists, social workers, or counselors who provide psychotherapy. Although medications won't cure an anxiety disorder, they can keep the symptoms under control and enable you to lead a normal, fulfilling life.

Medication is most helpful when there is clear disorder or, sometimes, a specific target symptom for a particular drug. Usually, a pattern of symptoms point to a specific chemical imbalance. Whenever an imbalance appears evident through a person's disordered behavior and emotional state, medication centers on modifying the strength of the signal or readjusting the balance among them.

Psychologists, social workers, and counselors sometimes work closely with a psychiatrist or other physician, who will prescribe medications when they are required. For some people, group therapy is a helpful part of treatment.

It's important that you feel comfortable with the therapy that the mental health professional suggests. If this is not the case, seek help elsewhere. However, if you've been taking medication, it's important not to discontinue it abruptly, as stated before. Certain drugs have to be tapered off under the supervision of your physician.
