Can we use calcium hydroxide under amalgam?
Studies have shown that calcium hydroxide “softens” under amalgam and resin-based composite restorations. When calcium hydroxide is used, a less soluble high-strength base material such as glass ionomer may be placed to overlie the calcium hydroxide.
What does calcium hydroxide do to pulp?
The initial effect of calcium hydroxide applied to exposed pulp is the development of a superficial three-layer necrosis. The firm necrosis causes slight irritation and stimulates the pulp to defense and repair. The observed sequence of tissue reactions is that which is expected when con- nective tissue is wounded.
What is the difference between Apexification and Apexogenesis?
Apexification is a method of inducing a calcified barrier at the apex of a nonvital tooth with incomplete root formation. Apexogenesis refers to a vital pulp therapy procedure performed to encourage physiological development and formation of the root end.
What does calcium hydroxide do in RCT?
The goal of endodontic treatment is the prevention and control of pulpal and periradicular infections. Calcium hydroxide (Ca(OH)2) has been widely used in endodontics as an intracanal medicament to eliminate the remaining microorganisms after chemomechanical preparation.
What is the most suitable solvent for calcium hydroxide?
PEG 400 is a suitable solvent for calcium hydroxide, and gives superior ion release into roots than a water solvent [31,39,40].
What is the solubility of calcium hydroxide?
WaterCalcium hydroxide / Soluble in
Description: A white, dry fine powder, free from lumps, possessing an alkaline, slightly bitter taste. Solubility in water: 1 g/630 ml at 25°C, 1 g/1,300 ml at 100°C.
What is calcium hydroxide solution?
calcium compounds Calcium hydroxide, also called slaked lime, Ca(OH)2, is obtained by the action of water on calcium oxide. When mixed with water, a small proportion of it dissolves, forming a solution known as limewater, the rest remaining as a suspension called milk of lime.
When do you use apexification and Apexogenesis?
Apexogenesis, which can be used when the pulp is injured but not necrotic, leaves the apical one-third of the dental pulp in the tooth, allowing the root to complete formation. Apexification stimulates cells in the periapical area of the tooth to form a dentin-like substance over the apex.
Why root canal treatment is necessary after Apexogenesis?
Healthy tissue then allows for continued root development. When root development is complete, a traditional root canal can be performed. Immature root, open apex, and inflamed pulp. Apexogenesis has resulted in root development, allowing a root canal to be performed.
When do you put calcium hydroxide in a root canal?
For such teeth, application of calcium hydroxide in the canal after drying with sterile absorbent paper points is helpful. This is because of its high alkalinity, which changes the acidic pH of periapical tissues to a more basic environment [2] [5] .
How is calcium hydroxide powder used in dentistry?
Prepare a moderately stiff paste by mixing Calcium Hydroxide Powder with sterile water. 4. Introduce the paste into the canal, packing the paste against the periapical tissue. Close the tooth with a temporary filling material and recall the patient in 2 weeks.
How do you increase the solubility of calcium hydroxide in water?
Just cool the solution. Calcium hydroxide is Retrograde soluble, meaning it’s solubility increases with lowering of temperature. At 0 Deg C, 20 Deg C and 100 Deg C, solubilities are 1.89, 1.65 and 0.66 gm/Liter, respectively.
What is the best material for apexogenesis and apexification?
Calcium hydroxide is the gold standard material used in apexogenesis and apexification. New technologies are promoting the growing interest in strategies used for vitality preservation and pulp regeneration.
What is apexogenesis?
Apexogenesis is a procedure that addresses the shortcomings involved with capping the inflamed dental pulp of an incompletely developed tooth. The goal of apexogenesis is the preservation of vital pulp tissue so that continued root development with apical closure may occur.
When should apexogenesis be initiated in pulp removal?
74. Conclusion The practitioner should strive to achieve root development through apexogenesis wherever possible. If this treatment fails or pulp is necrotic, apexification should be initiated.
What is apexogenesis/vital pulp therapy?
Apexogenesis/ vital pulp therapy The current terminology is vital pulp therapy (Walton and Torabinejad) “Apexogenesis is defined as treatment of a vital pulp in an immature tooth to permit continued root growth and apical closure. A vital pulp of an immature tooth may have a small exposure after trauma.”
