The four pelvic types are gynecoid, android, anthropoid, and platypelloid. The AP diameter versus the transverse diameter varies for each type.

The human pelvis is a bony structure that supports the lower part of the body and connects the legs to the spine. There are four different types of pelvic shapes: gynecoid, android, anthropoid, and platypelloid. These shapes are determined by the ratio of the anteroposterior (AP) diameter to the transverse diameter.

The gynecoid pelvis is the most common type and has an AP diameter that is equal to or greater than the transverse diameter. The android pelvis has an AP diameter that is greater than the transverse diameter, while the anthropoid pelvis has an AP diameter that is smaller than the transverse diameter. The platypelloid pelvis is the least common type and has a transverse diameter that is greater than the AP diameter.

The differences in pelvic types can affect childbirth and may require special delivery techniques. For example, women with a gynecoid pelvis have a higher chance of delivering vaginally, while women with an android pelvis may require a cesarean section. Understanding a woman's pelvic type is crucial for healthcare providers during pregnancy and childbirth.

In internal root resorption, the odontoblastic layer in pulp is damaged. In external root resorption, the cementoblastic layer in PDL (periodontal ligament) is damaged.

The cementum of the tooth is attached to the jaw bone with the help of a group of small fibres called the periodontal ligament. This helps to keep the tooth firmly in the socket where it belongs. Therefore, it can be said that the periodontal ligament serves as the tooth's support system.

In order to facilitate the severing of the periodontal tissue that connects the tooth particle to the surrounding alveolar bone along the superficial region of the tooth root, the elevator is utilised to impart a dislocation force to the tooth particle.

A sharp device called a periodontal knife has fewer blade dents than an elevator.  In order to release the tooth before extraction, it is utilised to cut or sever the Sharpie fibres in the periodontal tissue.

After the tooth has been removed, the periodontal ligament and potentially up to 1 mm of cancellous bone in the socket are removed using a long shaft surgical round bur.

The gingiva is shaped, incisions are chamfered, and interdental tissue is removed with a periodontal knife.

If a patient complains of extreme sharp pain in the calf muscle during a stress test, this is an indication of peripheral artery disease (PAD) or muscle strain.

During a stress test, patients may experience discomfort or pain due to increased physical activity. However, if a patient complains of an extreme sharp pain in the calf muscle during the test, it could be an indication of peripheral artery disease (PAD) or muscle strain. PAD occurs when there is a buildup of plaque in the arteries, leading to reduced blood flow to the legs and feet. Muscle strain, on the other hand, is caused by overuse, injury, or excessive stretching of the muscles.

It is crucial to monitor patients closely during a stress test and to stop the test immediately if the patient experiences severe pain, discomfort, or any other symptoms. The healthcare provider will perform a thorough physical examination and medical history review to determine the underlying cause of the pain. The provider may also order diagnostic tests such as an ankle-brachial index (ABI) or a vascular ultrasound to confirm the diagnosis of PAD.

Early detection and treatment of PAD can prevent complications such as heart attack, stroke, or limb amputation. Treatment options may include lifestyle changes such as exercise, diet, and smoking cessation, medication, or surgery.

HIV prophylaxis is crucial for individuals with low CD4 counts to reduce the risk of opportunistic infections and maintain overall health. The specific prophylaxis treatments depend on the CD4 cell count and the associated risks at each threshold.

HIV prophylaxis, or preventive treatment, is initiated when an individual's CD4 cell count decreases, as this indicates a weakened immune system. CD4 cells are essential for a healthy immune response, and HIV targets these cells, reducing their number over time.

When the CD4 count falls below 200 cells/mm³, prophylaxis against Pneumocystis pneumonia (PCP) is usually started, often with medications like trimethoprim-sulfamethoxazole. This threshold indicates a higher risk of developing opportunistic infections.

If the CD4 count drops below 100 cells/mm³, additional prophylaxis measures may be introduced to prevent other infections, such as toxoplasmosis. At this stage, the immune system is even more compromised, making the individual more susceptible to illnesses.

Lastly, when the CD4 count is less than 50 cells/mm³, prophylaxis against Mycobacterium avium complex (MAC) may be initiated. This is a severe stage of immune suppression, and the risk of acquiring opportunistic infections is significantly higher.

The worst instrument to clean a Class II furcation would be a toothbrush

A Class II furcation refers to a specific type of periodontal defect where there is a loss of bone and periodontal support, leading to a pocket formation between the roots of multi-rooted teeth. In this case, the worst instrument to clean a Class II furcation would be a toothbrush.

A toothbrush is designed primarily for cleaning the exposed surfaces of teeth and removing plaque from the gingival margins. However, it is not the most effective tool for reaching the depths of a Class II furcation. The bristles of a toothbrush are typically too large and lack the necessary flexibility to access and properly clean the furcation area.

Floss, on the other hand, can be more effective at cleaning interdental areas and may provide some level of cleaning for Class II furcations. Waterpik devices use pressurized water to clean interdental spaces and can also help in reaching furcation areas, although they might not be as effective as specialized periodontal instruments. Rubber stimulating tips are useful for massaging the gum tissue and promoting circulation but do not provide significant cleaning benefits for Class II furcations.

In conclusion, a toothbrush is the worst instrument for cleaning a Class II furcation due to its inability to access and clean the area effectively. More specialized periodontal instruments or techniques, such as periodontal scaling and root planing, would be more appropriate for addressing this type of periodontal defect.
