When the root is incompletely formed in adolescents and an infection occurs, apexification can be performed to maintain the tooth in position as the roots develop. In case of non-vital pulp: 1. Isolate the tooth with a rubber dam 2. perform root canal treatment. 3. Mix MTA and insert it to the apex of the tooth, creating a 3 mm thickness of ...
Exposure of the pulp causes pulpitis (an inflammation which can become irreversible, leading to pain and pulp necrosis, and necessitating either root canal treatment or extraction). [1] The ultimate goal of pulp capping or stepwise caries removal is to protect a healthy (or reversibly inflammed) dental pulp, and avoid the need for root canal ...
They are commonly used as pulp capping agents and lining materials for silicate and resin-based filling materials. [3] Calcium-silicate liner used as a pulp capping material. It is usually supplied as two pastes, a glycol salicylate and another paste containing zinc oxide with calcium hydroxide. On mixing, a chelate compound is formed.
Other ingredients can be added to the gelling agent solution including plasticizers such as glycerin or sorbitol to decrease the capsule's hardness, coloring agents, preservatives, disintegrants, lubricants and surface treatment. Since their inception, capsules have been viewed by consumers as the most efficient method of taking medication.
1.09 Alkylating agents: Altretamine: PO Alkylates DNA. Recurrent or advanced ovarian cancer Myelosuppression, peripheral neuropathy, seizures and hepatotoxicity (rare). Bendamustine: IV: Alkylates DNA. Chronic lymphocytic leukaemia, mantle cell lymphoma and non-Hodgkin's lymphoma. Myelosuppression, hypokalaemia and tachycardia. Busulfan: IV, PO ...
An Ag + species and a capping agent are added (although the polyol itself is also often the capping agent). The Ag + species is then reduced by the polyol to colloidal nanoparticles. [ 25 ] The polyol process is highly sensitive to reaction conditions such as temperature, chemical environment, and concentration of substrates.
The O 6 modifications are rapidly removed by treatment with the capping reagent as long as the capping step is performed prior to oxidation with I 2 /water. The synthesis of oligonucleotide phosphorothioates (OPS, see below) does not involve the oxidation with I 2 /water, and, respectively, does not suffer from the side reaction described above.
An example of this is adding a functional group such as decanoate. [2] The combination of an oil base and modification to decrease metabolic activation prevent medications from being fully released. [2] [3] This can result in length of activity of 2–4 weeks or more. [2] [3]
