Metal restorations, such as amalgam or metal crowns, are considered to be completely radiopaque in dental radiography, meaning that they absorb all of the X-rays and appear as a very bright white or opaque image on the radiograph.
Radiopaque objects or materials appear light or white on a radiograph because they absorb a significant amount of X-rays and prevent them from reaching the image receptor. In contrast, radiolucent objects or materials appear dark or black on a radiograph because they allow X-rays to pass through with little or no absorption.
In dental radiography, the degree of radiopacity or radiolucency of different structures and tissues can be used to identify and diagnose various dental and periodontal conditions, such as caries, periodontitis, and bone loss. Metal restorations are used in dentistry because of their radiopacity and durability, which allows them to be easily identified on radiographs and withstand the forces of chewing and biting.

Major symptom associated w/ leiomyomas (fibroids)?
The major symptom associated with leiomyomas, or fibroids, is heavy menstrual bleeding.
Leiomyomas, commonly known as fibroids, are non-cancerous growths that develop in or around the uterus. They can vary in size and number, and they may be located within the uterus, on the outside of the uterus, or within the uterine wall. Fibroids are very common, with up to 70% of women developing fibroids during their lifetime.
The most common symptom associated with fibroids is heavy menstrual bleeding, also known as menorrhagia. Women with fibroids may experience prolonged or frequent periods, with bleeding that lasts longer than usual or occurs more frequently than normal. This can lead to anemia and fatigue, as the body loses iron from the excessive bleeding.
Other symptoms of fibroids may include pelvic pressure or pain, which can feel like a dull ache or heaviness in the lower abdomen. Women with fibroids may also experience urinary frequency or urgency, which is caused by the fibroids pressing on the bladder. Constipation may occur if the fibroids are pressing on the bowel. Back pain is another common symptom of fibroids, which can be caused by the fibroids pressing on the nerves that run along the back. Painful intercourse, also known as dyspareunia, may also occur if the fibroids are pressing on the cervix or uterus.
It is important to note that some women may have fibroids without experiencing any symptoms. Fibroids are often discovered during a routine gynecological exam or imaging studies for other medical conditions. The symptoms and severity of fibroids can vary depending on the size, number, and location of the fibroids. Treatment options for fibroids may include medication, non-invasive procedures, or surgery, depending on the size and location of the fibroids, as well as the woman's age and desire for future fertility.

what causes _______ during ortho:
MOBILITY ?
PAIN?
INFLAMMATION?
During orthodontic treatment, mobility, pain, and inflammation are commonly caused by the movement of teeth and the pressure applied by orthodontic appliances.
Mobility occurs as the teeth are gradually repositioned, causing slight loosening in their sockets. This is a normal part of the orthodontic process, and as the teeth shift into their new positions, the mobility will subside.
Pain can occur due to the pressure and movement of the teeth. As the teeth shift, the surrounding tissues and ligaments may become sore and inflamed, resulting in discomfort. This is typically temporary and can be managed with over-the-counter pain relievers or orthodontic wax to alleviate any discomfort.
Inflammation can also occur as a result of the pressure applied by orthodontic appliances. This can lead to redness, swelling, and tenderness in the gums and surrounding tissues. Proper oral hygiene, including brushing and flossing regularly, can help reduce inflammation and keep the teeth and gums healthy during orthodontic treatment.
During orthodontic treatment, the following factors can cause mobility, pain, and inflammation:
1. Mobility: Orthodontic forces applied by braces or other appliances move teeth through the bone. As teeth shift, the periodontal ligament is compressed on one side and stretched on the other, temporarily causing tooth mobility.
2. Pain: The pressure exerted by orthodontic appliances on the teeth can stimulate nerve endings within the periodontal ligament, causing discomfort or pain. This is a common and temporary side effect of orthodontic treatment.
3. Inflammation: The movement of teeth can cause an inflammatory response in the surrounding tissues, as the body works to remodel the bone and periodontal ligament. Proper oral hygiene and anti-inflammatory medications can help manage inflammation during orthodontic treatment.

The ankle-brachial index can be measured by the blood pressure of the artery of the ankle to the blood pressure of the artery of the arm.
The ankle-brachial index test is a non-invasive diagnostic test. It is used to estimate the blood flow in the legs and feet. It is commonly used to analyze peripheral artery disease (PAD). It is a situation in which the blood vessels in the legs and feet become narrowed or stopped.
During the ABI test, a blood pressure cuff and a Doppler ultrasound device are used by the healthcare provider to measure the systolic blood pressure in the arm and at the ankle.

what is most common donor site for both FGG and CTG
The most common donor site for both Free Gingival Grafts (FGG) and Connective Tissue Grafts (CTG) is the palate, specifically the palatal mucosa.
This area provides a thick and keratinized tissue which is ideal for grafting procedures. Additionally, the palatal mucosa has a rich blood supply which aids in the healing process. While other donor sites such as the tuberosity and maxillary buccal mucosa may also be used, the palate remains the most commonly used and preferred donor site for FGG and CTG procedures.
It is important to note that the choice of donor site may depend on the specific needs of each patient and their individual anatomy. Therefore, a thorough evaluation by a periodontist or oral surgeon is necessary before deciding on the donor site for a grafting procedure.

3-4 wall intrabony defects by flap debridement and expanded
how to treat it?
3-4 wall intrabony defects refer to bone loss around a tooth that affects three or four sides of the tooth socket. These defects are usually caused by advanced periodontal disease or trauma. To treat 3-4 wall intrabony defects, a periodontist may recommend flap debridement.
Flap debridement is a surgical procedure that involves lifting the gum tissue and removing the infected or damaged tissue underneath. During this procedure, the periodontist will use special tools to remove the plaque and calculus from the tooth root surface and smooth out any rough areas. This will allow the gum tissue to reattach to the tooth and promote the growth of new bone and soft tissue. After flap debridement, the periodontist may also recommend an expanded procedure, such as guided tissue regeneration or bone grafting, to further promote the regeneration of lost bone tissue. Guided tissue regeneration involves the use of a membrane to direct the growth of new bone and soft tissue, while bone grafting involves adding bone tissue to the area to promote regeneration.
