The reason why we perform crown lengthening in an RCT (root canal treatment) with post and core because crown lengthening is often necessary to ensure adequate crown length and the ferrule effect, both of which are crucial for a successful restoration with a post and core and dental crown.
Crown lengthening is performed for two main reasons: to achieve the ferrule effect and to ensure adequate crown length. The ferrule effect is essential for the stability of the restoration, as it provides a 360-degree band of tooth structure for the crown to grip onto. This increases the strength and longevity of the restoration. Adequate crown length is necessary to provide proper support for the crown and to ensure sufficient tooth structure above the gumline, which helps prevent complications such as decay and tooth fracture.

Pregnant patient presents w/ unilateral flank pain radiating to the groin. UA shows microscopic/moderate hematuria. Negative for nitrates or leukocyte esterase. Next step?
The next step would be to order a renal ultrasound to evaluate for possible renal calculi.
Unilateral flank pain that radiates to the groin, along with microscopic or moderate hematuria, are classic symptoms of a kidney stone. The absence of nitrates or leukocyte esterase suggests that there is no concurrent urinary tract infection. Renal ultrasound is the first imaging modality of choice for evaluating suspected renal calculi due to its non-invasiveness, lack of radiation exposure, and ability to detect most types of stones. Other imaging modalities, such as CT scans or MRI, may be considered if the diagnosis remains unclear or if there are specific indications for their use. However, given the patient's pregnancy, radiation exposure should be minimized, making renal ultrasound a safer and more appropriate first step.

The rate of onset of anesthesia relies on which 3 characteristics?
Lipid solubility, blood flow and Molecular weight and chemical structure on these 3 characteristics the rate of onset of anesthesia releases.
The rate of onset of anesthesia relies on three key characteristics:
Lipid solubility: The degree to which an anesthetic agent can dissolve in lipids (fats) greatly affects its onset. Highly lipid-soluble agents can easily cross cell membranes, including the blood-brain barrier, and reach their target sites in the central nervous system (CNS) more rapidly.Consequently, the greater the lipid solubility of an anesthetic, the faster its onset of action.
Blood flow: The rate of blood flow to a particular body area or organ influences the delivery of anesthetic agents. Tissues or organs with high blood flow, such as the brain, heart, and lungs, receive anesthetic agents more quickly than those with lower blood flow.This, in turn, affects the onset of anesthesia. In general, increased blood flow accelerates the onset of anesthesia, while decreased blood flow delays it.
Molecular weight and chemical structure: The size and shape of anesthetic molecules impact their ability to diffuse through tissues and cell membranes. Smaller molecules typically diffuse more rapidly than larger ones, leading to a faster onset of anesthesia.Additionally, the chemical structure of an anesthetic agent may influence its binding to specific receptors in the CNS, which also plays a role in determining the rate of onset.
In summary, the rate of onset of anesthesia depends on the lipid solubility of the anesthetic agent, the blood flow to the target site, and the molecular weight and chemical structure of the agent. Understanding these factors can help guide the selection and administration of anesthetics to achieve the desired level of anesthesia within the appropriate timeframe.

what is the difference between preseptal and postseptal cellulitis?
Preseptal cellulitis refers to an infection of the tissues in front of the orbital septum, which is a layer of connective tissue that separates the eyelid from the eye socket.
This type of cellulitis is usually caused by a bacterial infection from an insect bite, scratch, or other injury to the eyelid. Preseptal cellulitis is less severe than postseptal cellulitis and typically does not involve the eye or vision.
Postseptal cellulitis, on the other hand, is a more severe infection that occurs behind the orbital septum, involving the eye and the tissues around it. This type of cellulitis can be caused by a variety of factors including sinusitis, trauma to the eye, or spread of infection from the teeth or nasal cavity. Postseptal cellulitis requires urgent medical attention as it can lead to serious complications such as vision loss, meningitis, or brain abscess if left untreated. Treatment for postseptal cellulitis often involves hospitalization and intravenous antibiotics.
The difference between preseptal and postseptal cellulitis lies in the location and severity of the infection. Preseptal cellulitis affects the eyelid and surrounding tissues anterior to the orbital septum, while postseptal cellulitis, also known as orbital cellulitis, involves infection posterior to the orbital septum within the orbit. Postseptal cellulitis is typically more severe, with potential complications like vision loss, and may require more aggressive treatment.
